Joint destruction necessitates tibiotalocalcaneal arthrodesis (TTCA) in cases of clinical deficits that cannot be controlled conservatively, possibly leading to sepsis. We aimed to compare the underlying etiology of posttraumatic joint destruction and the outcomes after TTCA in patients with a septic or aseptic history. Between 2010 and 2022, 216 patients with TTCA were retrospectively enrolled (septic TTCA (S-TTCA) = 129; aseptic TTCA (A-TTCA) = 87). Patient demographics, etiology, Olerud and Molander Ankle Scores (OMASs), Foot Function Index (FFI-D) scores, and Short Form-12 Questionnaire (SF-12) scores were recorded. The mean follow-up period was 6.5 years. Tibial plafond and ankle fractures were the most common causes of sepsis. The mean OMAS was 43.0; the mean FFI-D was 76.7; and the mean SF-12 physical component summary score was 35.5. All the scores differed significantly between the groups (p < 0.001). With an average of 11 operations until the arthrodesis was achieved, the S-TTCA patients underwent about three times as many operations as the A-TTCA patients (p < 0.001), and 41% of S-TTCA patients remained permanently unable to work (p < 0.001). The significantly worse results of S-TTCA compared to A-TTCA show the long and stressful ordeal that patients with a septic history suffer. Further attention must be paid to infection prophylaxis and, if necessary, early infection revision. [ABSTRACT FROM AUTHOR]

Purpose: Despite the extensive use of PROs in ankle fracture research, no study has quantified which PROs are most commonly used for assessing outcomes of patients who sustain fractures of the posterior malleolus. The purpose of this study was therefore to quantify which PROs are most commonly used for outcome research after posterior malleolus fractures. Methods: A systematic search was performed using the preferred reporting items for systematic reviews and meta-analyses guidelines. Articles were identified through Pubmed, EMBASE, Web of Science, and cochrane central register of controlled trials through May of 2021. Included articles were analyzed for the primary outcome of the most commonly reported PRO. Results: The American orthopedic foot and ankle ankle-hindfoot score (AOFAS) was the most commonly used PRO for assessment of posterior malleolus fracture outcomes, used in 37 of 72 studies (51.4%). The second and third most common were the olerud-molander ankle score (OMAS) (22 studies, 30.6%) and the visual analogue score (VAS) (21 studies, 29.2%). Eleven different PROs were used only once. Quality of evidence was graded as low given the percentage of studies that were observational or case series (68 of 72 studies, 94.4%). Conclusion: Investigators have used many different PROs to assess outcomes for posterior malleolus fractures, the most common of which are the AOFAS, OMAS, and VAS. Future investigators should attempt to unify outcome reporting for these injuries. [ABSTRACT FROM AUTHOR]

Introduction: Intramedullary nailing is the most frequent procedure used for the treatment of tibial fractures that do not involve the articular surfaces. The goal of this study is to analyse the clinical outcomes, time of surgery and use of fluoroscopy in patients with midshaft and distal tibial fractures treated with suprapatellar and infrapatellar nailing and compare the results between these different groups. Methods: A retrospective study was conducted, and patients were selected between the period of March 2018 and October 2019. The following variables were studied: age, gender, AO classification, time of surgery (minutes), time of fluoroscopy (seconds), quality of reduction in postoperative controls and 1 year follow-up (using the angles MPTA, LDTA, PPTA, ADTA). Functional outcomes were studied at 1 month and 1 year follow-up. The visual analogue scale was used to study and compare the postoperative pain of the patients. The Lysholm Knee Score was used to evaluate the functional outcomes of the patients. Results: A total of 80 patients meeting the inclusion criteria were included in this study. The suprapatellar approach was used in 44 patients and the infrapatellar in 36 patients. The time of surgery (p=0.008) and the mean time of use of fluoroscopy (p <0.001) difference were significant in favour of the suprapatellar approach. In the quality of reduction analysis, we have statistically significant results in the LDTA and ADTA angles. Also, in the evaluation of postoperative pain, significant difference was found in favour of the suprapatellar approach. Conclusion: In conclusion, our study compared the suprapatellar approach and the infrapatellar approach for the treatment of midshaft and distal tibia fractures with intramedullary nailing. The results showed lesser time of surgery and use of fluoroscopy, lower knee pain, and lower rate of malalignment with the suprapatellar approach than with the infrapatellar approach.

Bosworth lesions are fracture-dislocations of the ankle and are characterized by entrapment of the proximal segment of the fibula behind the posterior tubercle of the distal tibia. Treatment is challenging, mainly due to failure of a closed reduction. The aim of this study was to review the literature concerning this type of injury. A total of 103 patients with Bosworth fractures were included in the study. The analyzed studies yielded a total of 103 cases, of which 68% (n = 70) were male and 32% (n = 33) were female. Bosworth fractures are mainly due to accidental trauma (58.2%), sports-related injuries (18.4%), and traffic accidents (18.4%). More than 76% of the patients presented a Danis–Weber B fracture, 8.7% a type C fracture, and only 0.97% presented a type A fracture. In 92.2% of the patients, the attempted closed reduction was unsuccessful. A definitive treatment with open reduction and internal fixation (ORIF) was used in 96 patients (93.2%). The most frequent complication was post-traumatic arthritis (10.7%). Bosworth fractures are challenging. The available literature lacks adequate information about this fracture, and an approved standardized algorithm for treating such fractures is not available. [ABSTRACT FROM AUTHOR]

Background: Ankle fractures are among the most frequent fractures in the lower limb, predominantly affecting young people and representing approximately 9% of all fractures. Objective: To identify the factors associated with functionality in patients with closed ankle fracture. Material and methods: Observational and retrospective study. Records of people with a diagnosis of ankle fractures admitted to rehabilitation between January to December 2020 in a Physical Medicine and Rehabilitation Unit of a third level hospital were included. Age, sex, body mass index (BMI), days of disability, mechanism of injury, type of treatment, length of stay in rehabilitation, type of fracture and functionality were captured. Chi-squared and Student's t test were used to determine the association. Subsequently a multivariate analysis with binary logistic regression was performed. Results: The average age of the subjects was 44.8 years, the female sex was presented in 54.7%, the average BMI was 28.8%, 66% carried out a paid work activity, 65% received surgical treatment, the average time of disability was 140 days, the factors associated with functionality independently were age, pain, dorsiflexion and plantar flexion upon admission to rehabilitation. Conclusions: Ankle fractures occur in a young population and the factors associated with functionality were age, dorsiflexion, plantar flexion, and pain upon admission to rehabilitation.

Summary: Risk factors involved in the different osteoporotic fracture locations are not well-known. The results of this study suggest that there is not one typical profile characterising a particular fracture site but that the occurrence of a fracture may result from the combination of different bone, cognitive, and anthropometrics characteristics. Purpose: Risk factors involved in the different osteoporotic fracture locations are not well-known. The aim of this study was to identify the differences in bone, cognitive, and anthropometric characteristics between different fracture sites, and to determine whether the site of a fall-related fracture is related to a specific profile. Methods: One hundred six women aged 55 years and older with a recent fall-related fracture of the hip (n = 30), humerus (n = 28), wrist (n = 32), or ankle (n = 16) were included. Bone, cognitive, and anthropometric characteristics were first compared among the four fracture site groups. Then, a principal component analysis (PCA) was performed and a comparison was made between the four profiles identified by the first two PCA components. Results: The four fracture site groups differed significantly in their education level, bone mineral density (BMD), body mass index (BMI), fear of falling, and number of errors in the Trail Making Test B, an executive function test. Each of the four fracture sites was found in each four PCA profiles, albeit with a different distribution. The profiles differed mainly by bone, cognitive, and anthropometric characteristics, but also by fear of falling. Conclusions: The fall-related fracture sites differ significantly in anthropometric and bone parameters, in fear of falling and in cognitive abilities. There is not one typical bone, cognitive, and anthropometric profile characterising a particular fall-related site, but rather several possible profiles for a given site. This suggests that the fracture site depends on a combination of several characteristics of the patient. [ABSTRACT FROM AUTHOR]

Open reduction and internal fixation (ORIF) for unstable ankle fractures (AF) are relatively predictable with excellent outcomes. Rehabilitation strategies are still being debated after surgical intervention for AF: non-weight bearing and cast immobilization for six weeks after the surgical repair of unstable AF or early functional treatment with partial weight bearing. This study aimed to compare early weight bearing and functional outcomes and complications. Between April 2014 and March 2019, 1421 patients with AF underwent ORIF at 11 institutions (TRON group). The patients were divided into two groups: Group E started weight bearing within six weeks after surgery, and group L started weightbearing for more than six weeks after. To adjust for baseline difference between groups, a propensity score-matched algorithm was used to match Group E with Group L in a 1:1 ratio of 294 cases each. We compared the American Orthopedic Foot and Ankle Society (AOFAS) score as the functional outcome, the rate of wound dehiscence, superficial and deep infections, blistering, nonunion, neurapraxia, and reoperation at 3, 6, and 12 months after surgery. The mean period of non-weight bearing was significantly shorter in group E (3.68 ± 1.02 vs. 6.67 ± 1.43; P < 0.001). The mean period of cast immobilization term were shorter in group E (1.84 ± 1.35 vs. 2.65 ± 1.51; P < 0.001). There were no differences in the AOFAS score at any period. The rates of deep infection and reoperation in Group E were significantly lower than those in Group L (1.7% vs. 6.1%; P = 0.009, 2.0% vs. 7.8%; P = 0.002, respectively). There were no significant differences in superficial infection (9 vs. 15; P = 0.297), nonunion (9 vs. 15 P = 0.30), blistering (4 vs. 3; P = 1.00), neurapraxia (2 vs. 1; P = 1.00), and wound dehiscence (15 vs. 18; P = 0.72). Although functional outcome was similar depending on whether early weight bearing was allowed, the rates of deep infection and reoperation decreased in patients with early weight bearing. We recommend early postoperative weight bearing in patients with a surgically treated AF. [ABSTRACT FROM AUTHOR]

Background: Currently, the standard of treatment for trimalleolar (TM) fracture is osteosynthesis through open reduction and internal fixation (ORIF). This study assessed whether arthroscopically assisted reduction and minimally invasive surgery (AARMIS) can be an alternative surgical method for TM fractures. Methods: This retrospective cohort study included 49 patients with TM that were surgically treated. 27 patients received ORIF and 22 patients underwent AARMIS. At baseline, we recorded the patient's demographic features, fracture pattern (AO-OTA and Haraguchi classification), and surgical method. For postoperative results, we examined the patient's radiographic outcome, including time to union, quality of fracture reduction, as well as functional outcomes (American Orthopaedic Foot & Ankle Society ankle hindfoot score, ankle range of motion, and visual analog scale of pain) and perioperative complications. Results: At mean follow-up of 46.6 ± 24. 6 (ORIF) and 36.4 ± 18. 5 months (AARMIS), both groups had comparable radiographic outcomes. No significant difference in rates of early ankle OA were detected. In terms of functional outcome, VAS pain and AOFAS score at postoperative day 3, postoperative month 3, and at final follow-up were not different. In terms of range of motion, we did not find a significant difference in mean range of motion. Conclusion: Patients with TM fractures treated with AARMIS achieved satisfactory results and was not significantly different in radiographic and functional performance compared with ORIF. Level of Evidence: Level III, retrospective cohort study. [ABSTRACT FROM AUTHOR]

Recovery after ankle fracture surgery can be slow and even present functional deficits in the long term, so it is essential to monitor the rehabilitation process objectively and detect which parameters are recovered earlier or later. The aim of this study was (1) to evaluate dynamic plantar pressure and functional status in patients with bimalleolar ankle fracture 6 and 12 months after surgery, and (2) to study their degree of correlation with previously collected clinical variables. Twenty-two subjects with bimalleolar ankle fractures and eleven healthy subjects were included in the study. Data collection was performed at 6 and 12 months after surgery and included clinical measurements (ankle dorsiflexion range of motion and bimalleolar/calf circumference), functional scales (AOFAS and OMAS), and dynamic plantar pressure analysis. The main results found in plantar pressure were a lower mean/peak plantar pressure, as well as a lower contact time at 6 and 12 months with respect to the healthy leg and control group and only the control group, respectively (effect size 0.63 ≤ d ≤ 0.97). Furthermore, in the ankle fracture group there is a moderate negative correlation (−0.435 ≤ r ≤ 0.674) between plantar pressures (average and peak) with bimalleolar and calf circumference. The AOFAS and OMAS scale scores increased at 12 months to 84.4 and 80.0 points, respectively. Despite the evident improvement one year after surgery, data collected using the pressure platform and functional scales suggest that recovery is not yet complete. [ABSTRACT FROM AUTHOR]

Purpose: Trimalleolar ankle fractures (TAFs) are common traumatic injuries. Studies have described postoperative clinical outcomes in relation to fracture morphology, but less is known about foot biomechanics, especially in patients treated for TAFs. The aim of this study was to analyze segmental foot mobility and joint coupling during the gait of patients after TAF treatment. Methods: Fifteen patients, surgically treated for TAFs, were recruited. The affected side was compared to their non-affected side, as well as to a healthy control subject. The Rizzoli foot model was used to quantify inter-segment joint angles and joint coupling. The stance phase was observed and divided into sub-phases. Patient-reported outcome measures were evaluated. Results: Patients treated for TAFs showed a reduced range of motion in the affected ankle during the loading response (3.8 ± 0.9) and pre-swing phase (12.7 ± 3.5) as compared to their non-affected sides (4.7 ± 1.1 and 16.1 ± 3.1) and the control subject. The dorsiflexion of the first metatarsophalangeal joint during the pre-swing phase was reduced (19.0 ± 6.5) when compared to the non-affected side (23.3 ± 8.7). The affected side's Chopart joint showed an increased range of motion during the mid-stance (1.3 ± 0.5 vs. 1.1 ± 0.6). Smaller joint coupling was observed on both the patient-affected and non-affected sides compared to the controls. Conclusion: This study indicates that the Chopart joint compensates for changes in the ankle segment after TAF osteosynthesis. Furthermore, reduced joint-coupling was observed. However, the minimal case numbers and study power limited the effect size of this study. Nevertheless, these new insights could help to elucidate foot biomechanics in these patients, adjusting rehabilitation programs, thereby lowering the risk of postoperative long-term complications.

Background: The fixation method of syndesmotic injuries in ankle fractures remains controversial. The goal of the study was to compare radiographic and clinical outcomes between anterior inferior tibiofibular ligament (AITFL) anatomical repair with syndesmosis screw fixation in syndesmotic injuries. Methods: We analyzed 62 patients who were treated with AITFL anatomical repair or syndesmosis screw fixation for syndesmotic injuries in an advanced teaching hospital between March 2016 and March 2019. Fixation was performed with AITFL anatomical repair in 30 patients (AAR group) and syndesmosis screw in 32 patients (SS group). Radiographic evaluations were the differences in mean anterior and posterior (A difference and P difference) tibiofibular distance between injured and uninjured ankle computed tomography (CT) scan at 6 months postoperatively. Clinical evaluation of patients was done using the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle Hindfoot Score, the Olerud-Molander Ankle (OMA) score and visual analogue scale (VAS) score at 1, 3, 6 months and 1, 2 years postoperatively. Results: The A difference and P difference on CT was no differences (1.6 ± 0.8 mm, 1.3 ± 0.7 mm vs. 1.5 ± 0.7 mm, 1.2 ± 0.7 mm) between the two groups (All of P > 0.05). The AAR group had higher mean AOFAS score (65.6 ± 5.9, 82.3 ± 4.2, 87.6 ± 5.6 vs. 61.8 ± 5.2, 79.1 ± 4.0, 83.8 ± 4.9; P = 0.008, 0.003, 0.007) and higher mean OMA score (45.7 ± 8.7, 79.2 ± 6.5, 84.1 ± 5.3 vs. 40.4 ± 7.3, 74.8 ± 6.3, 80.3 ± 5.8; P = 0.012, 0.009, 0.010)) at 1, 3 and 6 months postoperatively. The AAR group had lower mean VAS scores (2.6 ± 1.2, 1.7 ± 0.7 vs. 3.4 ± 1.2, 2.2 ± 1.1; P = 0.018, 0.038) at 1 and 3 months postoperatively. Conclusions: The results of this study suggest that the AITFL anatomical repair technique could effectively improve ankle function during daily activity. Therefore, AITFL anatomical repair technique is expected to become a better fixation method for syndesmotic injuries. [ABSTRACT FROM AUTHOR]

Background: The distal tibiofibular syndesmosis (DTS) is a complex fibrous joint that contributes to the stability and weight-bearing function of the ankle. As such, repair of DTS injury is required, providing fixation strength while maintaining ankle range of motion. The aim of this study was to compare a new elastic fixation technique, using an encircling and binding technique, for DTS stabilization, compared to the traditional cortical bone screw fixation. Methods: This was a retrospective analysis of 67 patients treated for a DTS injury at our hospital, between June 2019 and June 2021. Of them, 33 were treated with encircling and binding (EB group) and 34 using a cortical screw (CS group). The following outcomes were compared between groups: time to inferior tibiofibular fixation; length of hospital stay; time to partial weight bearing; time to complete weight bearing; complications; imaging data; and functional scores. Results: Successful stabilization was achieved in all cases, with a mean follow-up period of 15.78 ± 2.97 months. Time to fixation and time to partial and complete weight bearing were shorter for the EB than that for the CS group. The length of hospital was not different between groups. With regard to complications, a superficial infection developed in one patient in each group, with wound healing achieved after active treatment. Screw fracture occurred in two patients in the CS group. At 3 months post-surgery, the American Foot Surgery Association Ankle-Hindfoot score (AOFAS) was higher and the pain score lower for the EB than that for the CS group, but with no between-group difference at the final follow-up. On imaging, the tibiofibular clear space and tibiofibular overlap were not different between groups. Conclusions: DTS fixation using encircling and binding yielded better clinical and functional outcomes than did cortical screw fixation at 3 months post-surgery, with no difference at the final follow-up. This novel fixation technique provides firm fixation, combined with earlier return to postoperative exercise and recovery of ankle function. [ABSTRACT FROM AUTHOR]

Background: Ankle fracture is a common injury that is treated at Addis Ababa Burn, Emergency, and Trauma Hospital. Previous studies show that there are mixed functional outcomes after surgically treated ankle fractures. Methods: After Ethical clearance was obtained from the ethical review committee of St. Paul Millennium Medical College, a retrospective cross-sectional study was conducted on 122 patients from September to October 2021. Patients fulfilling the inclusion criteria were called through phone and verbal consent was obtained, and the patients' responses were recorded with Olerud and Molander ankle outcome score (OMAS). For those study subjects who were unanswered to phone calls or non-functioning cell phones were repeated at least two times per week during the data collection period. The collected data were coded, entered, checked for its completeness, cleaned, and analyzed using SPSS Version 22. Descriptive statistics were presented with frequency, percentage, text, and graphs. Finally, the strength of association between functional outcome of ankle fracture and independent variables were evaluated using the Chi-square test, and a P-value < 0.05 was declared to be statistically significant. Results: Out of the total 122 patients, 72.1% of study subjects were males, and the mean OMAS for males and females was 76.79, and 75.65, respectively. Among all ankle fractures, nearly two-thirds (63.1%) of them were closed fractures, which are initially stabilized with splinting, open reduction, and internal fixation (ORIF), and external fixation were 77%, 13.9%, and 9%, respectively, whereas 83.3% definitive management of operatively treated ankle fracture was open reduction and internal fixation. In this study, the score of Olerud and Molander was 82.9% patients 'good' or 'excellent,' whereas 10.5% and 4.5% were fair and poor, respectively. In the present study patients with 40 years and younger (p-value, 0.022) and early surgical treatment (p-value 0.02) were strongly associated with the positive functional outcome of ankle surgery. Conclusion: Even though the surgical treatment of ankle fracture results in good postoperative functional outcomes, restores ankle function, and allows good mobility of the ankle joint, still some patients experience few restrictions in functional activities of 2–5-year post-surgical treatment.

Purpose: Ankle fractures may cause disability and socioeconomic challenges, even when managed in a high-resource setting. The outcomes of ankle fractures in sub-Saharan Africa are not widely reported. We present a systematic review of the patient-reported outcomes and complications of patients treated for ankle fractures in sub-Saharan Africa. Methods: Medline, Embase, Google Scholar and the Cochrane Central Register of Controlled Trials were searched, utilising MeSH headings and Boolean search strategies. Ten papers were included. Data included patient demographics, surgical and non-surgical management, patient-reported outcome measures and evidence of complications. Results: A total of 555 patients with ankle fractures were included, 471 of whom were followed up (range 6 weeks–73 months). A heterogenous mix of low-quality observational studies and two methodologically poor-quality randomised trials demonstrated mixed outcomes. A preference for surgical management was found within the published studies with 87% of closed fractures being treated operatively. A total of five different outcome scoring systems were used. Most studies included in this review were published by well-resourced organisations and as such are not representative of the actual clinical practice taking place. Conclusion: The literature surrounding the clinical outcomes of ankle fractures in sub-Saharan Africa is sparse. There appears to be a preference for surgical fixation in the published literature and considering the limitations in surgical resources across sub-Saharan Africa this may not be representative of real-life care in the region.

Purpose: The primary aim was to analyse the lateral malleolus morphology with a focus on the shape of the distal fibula for IM fixation of the fibula in infra- and transsyndesmotic fracture patterns. The secondary aim was to propose a treatment algorithm according to the lateral malleolar anatomy. Methods: 77 healthy, skeletally mature volunteers underwent CT scanning of the ankle. The fibula medullary canal and its cortical thickness were quantitatively analysed at 4 different levels measured from the fibular tip (1.5 cm, 3.0 cm, 4.5 cm, and 6.0 cm). A geometric classification was proposed, and a decision algorithm was developed. Statistical significance was set at a p-value < 0.05. Results: The smallest diameter of the medullary canal of the fibula was at 6.0 cm from the tip of the fibula, in 98.2% of the ankles. The distal fibula can be classified into triangular and rectangular type, according to the cortical thickness index (p < 0.0001). In 16.7% ankles, the internal diameter of the fibula at 6.0 cm was equal or narrower than 3.5 mm (p < 0.05). Conclusion: The shape of the distal fibula as evaluated by CT-guided analysis allows for IM osteosynthesis of the lateral malleolus in 83% of individuals. In our study, the smallest diameter of the medullary canal of the fibula was located 6.0 cm from the tip of the lateral malleolus. Coronal CT evaluation is advantageous in indicating which type of IM implant should be used safely for infra- and transsyndesmotic fracture patterns, potentially reducing intraoperative risks.

• Adolescent transitional ankle fracture is a specific type of fracture that occurs during the adolescent growth phase. • Arthrography is an important surgical method in pediatric orthopedic surgery. • In order to improve the success rate of closed reduction, we use the joystick technique to transitional ankle fracture. • The arthrography-assisted joystick technique provide an important guidance to transitional ankle fracture. To investigate the feasibility and short-term clinical efficacy of the arthrography-assisted joystick technique for the treatment of adolescent transitional ankle fracture. A retrospective analysis was performed in 10 adolescent transitional ankle fracture patients treated with the arthrography-assisted joystick technology. There were 7 male patients and 3 female patients with a mean age of 12.80 ± 1.81 years (range: 10–16 years). All cases were closed fractures, and the operation was performed after the failure of manual reduction [X-ray or computed tomography (CT) showed that the fracture gap was > 2 mm]. After the operation, X-ray or CT examination was performed to assess reduction of the fracture. Ankle function and fracture healing were evaluated by assessing the imaging indexes and evaluating the American Orthopedic Foot and Ankle Society (AOFAS) ankle score system. All patients were followed up for an average period of 12.00 ± 3.40 months (range: 8–20 months). The operation time was 40.50 ± 16.90 min (range: 25–80 min), the number of intraoperative fluoroscopy sessions was 18.70 ± 5.91 (range: 10–30 sessions), and the intraoperative blood loss was 5.90 ± 3.38 ml (range: 2–10 ml). X-ray examination showed that all cases achieved bone healing. The fracture healing time was 11.00 ± 2.45 weeks (range: 8–16 weeks). Four cases showed early closure of the epiphysis. The AOFAS scoring system evaluation results of these 10 pediatric cases were excellent. The arthrography-assisted joystick technique for the treatment of adolescent transitional ankle fracture offers advantages, such as minimal trauma, simple operation, ideal reduction effect, and the recent curative effect is satisfactory.

Metal screws are the most widely used in treating syndesmotic injuries, but failure and the rigidity of the screws can threaten the success of the treatment and increase the cost of care. We have provided an alternative with an olive wire and external fixator(OWEF) used for syndesmotic fixation. A retrospective longitudinal follow-up study was conducted. From February 2011 to January 2018, 58 of 72 patients with ankle fractures and associated syndesmotic disruption were treated with either screw or OWEF fixation. The costs, complications, and clinical outcomes using Olerud-Molander score and Visual Analog score in screw and OWEF fixation group were compared. We found the severity of the injury, BMI of the patients and the different fixation methods were determinants of the complications and clinical outcomes. But if no malreduction of the syndesmosis was present, no difference in clinical result was detected. The OWEF method appeared to be at least equally functional and effective to screw fixation while maintaining possible lower complication rate. Level 3 [ABSTRACT FROM AUTHOR]

Ankle fractures are the most common fractures of the lower extremity and occur in women and men regardless of their ages. The operative treatment is often named to be a “rookie procedure” but after careful diagnostics, more cases reveal to be more complex than assumed. Despite of being fixed correctly, 10 % of the patients suffer posttraumatic arthrosis causing significant loss of quality of life and work ability in our economic systems. In this review, we present our pathways and standards of current therapy strategies. [ABSTRACT FROM AUTHOR]

Talus fractures were accompanied historically with unsatisfying results as the osseus perfusion is vulnerable. Especially dislocated neck and body fractures of the talus have high incidences of posttraumatic avascular necrosis and arthritis of the talus and ankle, respectively. Main treatment goals are exact anatomic reduction and fixation as joint in-congruency lead to early osteoarthritis. The main emphasis of this article is to give an overview of the different talar fracture types with relevant prognostic implications and to discuss the influence of immediate definitive surgical osteosynthesis of the talus. To date the more recent studies showed that after emergency reposition and immobilization delayed definitive osteosynthesis of the talus had no prognostic disadvantages. [ABSTRACT FROM AUTHOR]

Background: One of the most frequent injuries that orthopedic surgeons treat is an ankle fracture. There are more ankle fractures today prevalent in this patient population as the frequency of diabetes mellitus (DM) has increased. Objective: The current study was to look at how well for Pott's fractures, open reduction internal fixation with plates and screws were successful of the ankle joint in diabetic patients. Patients and methods: A descriptive follow up study was conducted on 30 patients with ankle Pott's fractures visiting the orthopedic outpatient clinic of Zagazig University Hospital. Internal fixation and open reduction were used to treat all patients. Operative fixation was done through ORIF by plate and screws according to AO principles of periarticular fracture fixation. Results: The high union rate occurs mainly at week 10 at higher percent (74%) in controlled diabetic patients, while union rate in uncontrolled diabetic patients was delayed till 6 months. Patients with DM experience higher complication rates with both open and closed methods for ankle fractures. People with poorly controlled diabetes who have high HbA1c levels experience more complications than those with well-controlled diabetes. Conclusion: Bimalleolar ankle fractures respond well to surgical treatment in controlled diabetic patients, providing good functional outcome. [ABSTRACT FROM AUTHOR]

Purpose: Syndesmotic screw removal following acute syndesmotic injury is a commonly performed procedure. However, recent studies suggest that the removal does not result in improved patient reported outcome, while the procedure has proved not to be without complications. The aim of this study was to present a health-economic evaluation of on-demand removal (ODR) compared to routine removal (RR) of the syndesmotic screw. Methods: Data were collected from the RODEO trial, a randomized controlled non-inferiority trial comparing functional outcome of ODR with RR. Economic evaluation resulted in total costs, costs (in Euro) per quality adjusted life year (QALY) and costs per point improvement on the Olerud Molander Ankle Score (OMAS). This included both direct and indirect costs. Results: Total costs for ODR were significantly lower with a mean difference of 3160 euro compared to RR (p < 0.001). The difference in QALY was not significant. The difference in OMAS at 12 months was 1.79 with an incremental cost-effectiveness ratio (ICER) of €-1763 (p = 0.512). The ICER was well below the willingness to pay. Although unit costs might vary between hospitals and countries, these results provide relevant data of cost-effectiveness. Conclusion: The clinical effectiveness of both ODR and RR can be considered equal. The costs are lower for patients treated with ODR, which leads to the conclusion that ODR is cost-effective.

Background: Multiple authors have highlighted the increased incidence of occult posterior malleolar fractures (PMFs) with spiral tibial shaft fractures, although other reported associated risks of intra-articular extension have been limited. The aim of our study is to investigate both PMFs and non-PMFs intra-articular extensions associated with tibial diaphyseal fractures to try to determine any predictive factors. Methods: We undertook a retrospective review of a prospectively collected database. The inclusion criteria for this study were any patient who had sustained a diaphyseal tibial fracture, who had undergone surgery during the study period and who had also undergone a CT scan in addition to plain radiographs. The study time period for this study was between 01/01/2013 and 9/11/2021. Results: Out of 764 diaphyseal fractures identified, 442 met the inclusion criteria. A total of 107 patients had PMF extensions (24.21%), and a further 128 patients (28.96%) had intra-articular extensions that were not PMF's. On multivariate analysis, spiral tibial fracture subtypes of the AO/OTA classification (OR 4.18, p < 0.001) and medial direction of tibial spiral from proximal to distal (OR 4.38, p < 0.001) were both significantly associated with PMF. Regarding intra-articular fractures, multivariate analysis showed significant associations with non-spiral (OR 4.83, p < 0.001) and distal (OR 15.32, p < 0.001) tibial fractures and fibular fractures that were oblique (OR 2.01, p = 0.019) and at the same level as tibia fracture (OR 1.83, p = 0.045) or no fracture of the fibular (OR 7.02, p < 0.001). Conclusion: In our study, distal tibial articular extension occurs in almost half of tibial shaft fractures. There are very few fracture patterns that are not associated with some type of intra-articular extension, and therefore, a low threshold for preoperative CT should be maintained. Level of evidence: 4. [ABSTRACT FROM AUTHOR]

Purpose: The anterolateral distal tibial rim (anterior malleolus, AM) is frequently fractured in malleolar fractures. The aim of this study was to evaluate the medium-term outcomes of malleolar fractures involving the AM. Methods: Among 100 patients with AM fractures that were treated over a 10-year period, 50 patients were available for follow-up. Outcome was assessed with the Olerud Molander Ankle Score (OMAS), the Foot Function Index (FFI-D), the EuroQol (EQ)-5D-5L Index, the EQ-VAS and the AOFAS Ankle-Hindfoot Score. Type 1 AM fractures (bony syndesmotic avulsions) were fixed surgically with either a suture anchor or a transosseous suture in 11 of 22 cases (50%). Among type 2 AM fractures (with incisura and joint involvement), 68% were treated surgically with screw fixation. All three type 3 AM fractures (anterolateral tibial plafond impaction) were treated surgically with either screw or plate fixation. Results: At follow-up, the median OMAS was 75, the FFI-D 19, the EQ-5D-5L-Index 0.88, the EQ-VAS 70, and the AOFAS score 93. Assuming that the fracture severity increases from Supination–External Rotation to Pronation–External Rotation and Pronation–Abduction injuries, the AOFAS score (p < 0.001), OMAS score (p = 0.009), and FFI-D (p = 0.041) all showed a significantly inferior clinical outcome with increasing fracture severity. Patients who required surgical revision (n = 5) showed a significantly inferior outcome with the OMAS (p = 0.019). Conclusions: A differentiated treatment protocol tailored to dislocation, size, incisura involvement and joint impaction leads to favourable outcomes in complex malleolar fractures involving the AM. More data are needed on the outcome of AM fractures that are still commonly underestimated and overlooked. [ABSTRACT FROM AUTHOR]

Purpose: Convolutional neural networks (CNNs) are increasingly being developed for automated fracture detection in orthopaedic trauma surgery. Studies to date, however, are limited to providing classification based on the entire image—and only produce heatmaps for approximate fracture localization instead of delineating exact fracture morphology. Therefore, we aimed to answer (1) what is the performance of a CNN that detects, classifies, localizes, and segments an ankle fracture, and (2) would this be externally valid? Methods: The training set included 326 isolated fibula fractures and 423 non-fracture radiographs. The Detectron2 implementation of the Mask R-CNN was trained with labelled and annotated radiographs. The internal validation (or 'test set') and external validation sets consisted of 300 and 334 radiographs, respectively. Consensus agreement between three experienced fellowship-trained trauma surgeons was defined as the ground truth label. Diagnostic accuracy and area under the receiver operator characteristic curve (AUC) were used to assess classification performance. The Intersection over Union (IoU) was used to quantify accuracy of the segmentation predictions by the CNN, where a value of 0.5 is generally considered an adequate segmentation. Results: The final CNN was able to classify fibula fractures according to four classes (Danis-Weber A, B, C and No Fracture) with AUC values ranging from 0.93 to 0.99. Diagnostic accuracy was 89% on the test set with average sensitivity of 89% and specificity of 96%. External validity was 89–90% accurate on a set of radiographs from a different hospital. Accuracies/AUCs observed were 100/0.99 for the 'No Fracture' class, 92/0.99 for 'Weber B', 88/0.93 for 'Weber C', and 76/0.97 for 'Weber A'. For the fracture bounding box prediction by the CNN, a mean IoU of 0.65 (SD ± 0.16) was observed. The fracture segmentation predictions by the CNN resulted in a mean IoU of 0.47 (SD ± 0.17). Conclusions: This study presents a look into the 'black box' of CNNs and represents the first automated delineation (segmentation) of fracture lines on (ankle) radiographs. The AUC values presented in this paper indicate good discriminatory capability of the CNN and substantiate further study of CNNs in detecting and classifying ankle fractures.

Introduction: Complex ankle fractures frequently include the posterior malleolus (PM). Despite advances in diagnostic and treatment strategies, PM fracture involvement still predisposes to worse outcomes. While not incorporated into the most common PM fracture classifications, the presence of an intercalary fragment (ICF) complicates treatment. This study aims to describe the incidence, morphology, and location of ICFs in PM fractures. Materials and methods: A total of 135 patients with a mean age of 54.4 (SD ± 18.9) years and PM fractures were analyzed for the presence of an ICF. Patients with an ICF were compared to those without in terms of age, gender, and treatment received. Characteristics of the ICFs in terms of location and size were assessed. Furthermore, the presence of an ICF in relation to the PM fracture classification according to Haraguchi et al., Bartoníček/Rammelt et al., and Mason et al. was investigated. Results: ICFs presented in 55 (41%) of the 135 patients. Patients with an ICF were younger, and the PM was more often operatively treated when compared to patients without an ICF. A posterolateral approach was used significantly more often in patients with an ICF. Almost all ICFs were found in the posterolateral (58%) and posterocentral (35%) regions. The majority of fragments were found in Bartoníček/Rammelt type 2 fractures, the most common fracture type. Bartoníček/Rammelt type 3 fractures had the highest relative frequency of ICFs. Conclusion: ICFs are frequently found in PM fractures; however, they are not incorporated into any of the common classifications. They are generally found in younger patients and associated with more complex PM fractures. As they can complicate reduction of the main fragment and may require direct exposure to restore joint congruency, ICFs should be considered in PM fracture classifications. Due to their location, the majority of ICFs are able to be accessed using a posterolateral approach. [ABSTRACT FROM AUTHOR]

This study reviews the current evidence on the indications and outcomes of the posterolateral approach in the treatment of posterior malleolar fractures. PubMed and Google Scholar search engines were used to construct a review of the literature for all studies detailing the posterolateral approach for posterior malleolar fracture fixation. A total of 11 studies met our inclusion criteria. In total, 332 fractures were identified. Overall superficial infection occurred in 4.5%, skin necrosis in 4.5%, and nerve injury in 4.5%. Hardware irritation that required removal occurred in 13.6%. None of the hardware removals involved posterior malleolus fixation. A total of 51 (15.4%) cases of arthritis were reported, follow-up ranged from a mean of 5.3 months to a mean 7.9 years. Regardless the majority of patient reported outcomes were excellent/good at final follow-up. Thresholds for joint reduction were not uniformly described or even quantified at all in some of the included studies. Variable indications for fixation were reported without reference to posterior malleolus fracture morphology. The posterolateral approach provides a satisfactory approach for fracture reduction with similar complication rates to that reported for other ankle fracture approaches. Further research is required on posterior malleolus fracture morphology, optimal fracture fixation and longer term functional and radiological outcomes. Levels of Evidence: Level III: Systematic review of retrospective cohort studies [ABSTRACT FROM AUTHOR]

YouTube is a non-peer-reviewed platform with a large library of healthcare-related videos which attempt to provide educational content. The goal of this study is to analyze the quality, absorbability, and educational content of videos available to patients on YouTube regarding ankle fractures. On May 31, 2022, over 550 videos populated the initial search of "ankle fracture" within YouTube's platform. The first 100 videos were reviewed, and 62 videos were included in the final analysis. Video characteristics were recorded and evaluated. Videos were assessed using three objective scoring systems: (1) the Journal of American Medical Association (JAMA) benchmark criteria, (2) the Patient Education Materials Assessment Tool for audio and visual materials (PEMAT), and (3) the novel Ankle Fracture Content Score (AFCS). Each scoring system had high internal consistency and interrater reliability. The mean JAMA, PEMAT understandability, PEMAT actionability, and AFCS were 2.92, 61.85%, 16.38%, and 4.67, respectively. No association was seen between video popularity metrics and quality of information. The understandability of the patient-targeted videos was greater than those targeted at healthcare professionals (P = 0.049). The information regarding ankle fractures available on YouTube for patient education is poor with no correlation between quality and popularity. This study illustrates the need for future collaboration between YouTube and trusted medical societies to provide patients with the highest quality information. [ABSTRACT FROM AUTHOR]

Background: Ankle fractures are among the most common physeal fractures in children. When surgical management is warranted, subsequent hardware removal remains controversial. This study was designed to determine rates of hardware removal in patients with physeal ankle fractures and identify risk factors for removal. Procedure data was utilized to compare rates of subsequent ankle procedures in patients with hardware removed and hardware retained. Methods: We conducted a retrospective cohort study utilizing data from the Pediatric Health Information System (PHIS) for the years 2015 through 2021. We longitudinally followed patients treated for distal tibia physeal fractures to determine the rates of hardware removal and subsequent ankle procedures. Patients with open fractures or polytrauma were excluded. We used univariate, multivariate, and descriptive statistics to characterize the rates of hardware removal, identify factors associated with removal, and assess the rates of subsequent procedures. Results: This study included 1008 patients who underwent surgical management of a physeal ankle fracture. The mean age at index surgery was 12.6 years with an SD of 2.2 years, and 60% of patients identified as male. Two hundred forty-two patients (24%) had their hardware removed at an average time of 276 days (range, 21-1435 days) following index surgery. Patients with Salter Harris III (SH-III) or Salter Harris IV (SH-IV) fractures had hardware removed more often than patients with Salter-Harris II (SH-II) fractures (28.9% vs 11.7%, P <.01). Four-year rates of subsequent ankle procedures are similar between patients with hardware removed and hardware retained. Conclusion: The rate of hardware removal in children with physeal ankle fractures is higher than previously reported. Patients of younger age, higher income, and with fractures involving the epiphysis (SH-III and SH-IV) are more likely to undergo hardware removal. Level of Evidence: Level III, retrospective study.

Background: In current literature, the benefit of postoperative physiotherapy versus postoperative instructions by treating specialist only remains unclear. The aim of this review is to systematically assess existing literature regarding the functional outcome of postoperative physiotherapy compared to postoperative instructions by treating specialist only in the rehabilitation of patients with an ankle fracture. The secondary aim is to determine if there is a difference in ankle range of motion, strength, pain, complications, quality of life, and patient's satisfaction between these 2 rehabilitation methods. Methods: For this review, the PubMed/MEDLINE, PEDro, Embase, Cochrane, and CINAHL databases were searched for studies that compared postoperative rehabilitation groups. Results: The electronic data search detected 20 579 articles. After exclusion, 5 studies with a total of 552 patients were included. Overall, no significant benefit in functional outcome of postoperative physiotherapy was seen compared to the instructions-only group. One study even found a significant benefit in favor of the instructions-only group. An exemption for beneficial effect of the use of physiotherapy could be made for younger patients, as 2 studies described younger age as a factor for better outcomes (functional outcome and ankle range of motion) in the postoperative physiotherapy group. Patients' satisfaction, described by one study, was found to be significantly higher in the physiotherapy group (P =.047). All other secondary aims showed no significant difference. Conclusion: Because of the limited number of studies and the heterogeneity among studies, a valid conclusion about the general effect of physiotherapy cannot be formed. However, we identified limited evidence suggesting a possible benefit of physiotherapy in younger patients with an ankle fracture in functional outcome and ankle range of motion.

Objective: Spiral fracture of tibia combined with posterior malleolar fracture (PMF) is a special and regular injury. There is no uniform fixation method for PMF in this kind of injury. Intramedullary nail is the first choice for the treatment of tibial spiral fracture. We proposed a minimally invasive percutaneous screw combined with intramedullary nail technology to fix the PMF in the tibial spiral fracture. This study aims to explore the effectiveness and advantages of this technology. Materials and methods: From January 2017 to February 2020, 116 cases of spiral fracture of tibia combined with PMF who were operated in our hospital were divided into Fixation Group (FG) and No Fixation Group (NG) according to whether PMF was fixed. After minimally invasive percutaneous screw fixation of ankle fracture in FG patients, the tibial intramedullary nail was inserted to fix the fracture. Collected the operation and postoperative recovery of the two groups of patients, including the operation time, intraoperative blood loss, AOFAS score, VAS score and dorsiflexion restriction of ankle joint at the last follow-up, and compared whether there is any difference between the two groups of patients. Results: The fracture of both groups healed.2 patients in NG had secondary displacement of PMF during operation, and the fracture finally healed after fixation. There were statistical differences between the two groups in terms of operation time, AOFAS score and weight bearing time. The operation time of FG was 67.9±11.2 min, and that of NG was 60.8±9.4 min; The weight bearing time of FG was 57.35±34.72 days, and that of NG was 69.17±21.43 days; The AOFAS score of FG was 92.50±3.46, and that of NG was 91.00±4.16. There were no significant difference in blood loss, VAS and dorsiflexion restriction of ankle joint between the two groups. The blood loss of FG was 66.8±12.3 ml, the blood loss of NG was 65.6±11.7 ml, the VAS score of FG was 1.37±0.47, the VAS score of NG was 1.43±0.51, the dorsiflexion restriction of FG was 5.8±4.1; the NG was 6.1±5.7. Conclusion: For the injury of tibial spiral fracture combined with PMF, our fixation technology can achieve minimally invasive fixation of PMF with percutaneous screws on the basis of intramedullary nail fixation of tibial fracture, promoting early functional exercise of ankle joint and early weight bearing of patients. This fixation technology is also characterized by simple and fast operation. [ABSTRACT FROM AUTHOR]

Background: Transsyndesmotic fixation with suture buttons (SBs), posterior malleolar fixation with screws, and anterior inferior tibiofibular ligament (AITFL) augmentation using suture tape (ST) have all been suggested as potential treatments in the setting of a posterior malleolar fracture (PMF). However, there is no consensus on the optimal treatment for PMFs. Purpose: To determine which combination of (1) transsyndesmotic SBs, (2) posterior malleolar screws, and (3) AITFL augmentation using ST best restored native tibiofibular and ankle joint kinematics after 25% and 50% PMF. Study Design: Controlled laboratory study. Methods: Twenty cadaveric lower-leg specimens were divided into 2 groups (25% or 50% PMF) and underwent biomechanical testing using a 6 degrees of freedom robotic arm in 7 states: intact, syndesmosis injury with PMF, transsyndesmotic SBs, transsyndesmotic SBs + AITFL augmentation, transsyndesmotic SBs + AITFL augmentation + posterior malleolar screws, posterior malleolar screws + AITFL augmentation, and posterior malleolar screws. Four biomechanical tests were performed at neutral and 30° of plantarflexion: external rotation, internal rotation, posterior drawer, and lateral drawer. The position of the tibia, fibula, and talus were recorded using a 5-camera motion capture system. Results: With external rotation, posterior malleolar screws with AITFL augmentation resulted in best stability of the fibula and ankle joint. With internal rotation, all repairs that included posterior malleolar screws stabilized the fibula and ankle joint. Posterior and lateral drawer resulted in only small differences between the intact and injured states. No differences were found in the efficacy of treatments between 25% and 50% PMFs. Conclusion: Posterior malleolar screws resulted in higher syndesmotic stability when compared with transsyndesmotic SBs. AITFL augmentation provided additional external rotational stability when combined with posterior malleolar screws. Transsyndesmotic SBs did not provide any additional stability and tended to translate the fibula medially. Clinical Relevance: Posterior malleolar fixation with AITFL augmentation using ST may be the preferred surgical method when treating patients with acute ankle injury involving an unstable syndesmosis and a PMF ≥25%.

Background: Trauma is still a major cause of mortality in people < 50 years of age. Biomarkers are needed to estimate the severity of the condition and the patient outcome. Methods: Cell-free DNA (cfDNA) and further laboratory markers were determined in plasma and serum of 164 patients at time of admission to the emergency room. Among them were 64 patients with severe trauma (Injury Severity Score (ISS) ≥ 16), 51 patients with moderate trauma (ISS < 16) and 49 patients with single fractures (24 femur neck and 25 ankle fractures). Disease severity was objectified by ISS and Glasgow Coma Scale (GCS). Results: cfDNA levels in plasma and serum were significantly higher in patients with severe multiple trauma (SMT) than in those with moderate trauma (p = 0.002, p = 0.003, respectively) or with single fractures (each p < 0.001). CfDNA in plasma and serum correlated very strongly with each other (R = 0.91; p < 0.001). The AUC in ROC curves for identification of SMT patients was 0.76 and 0.74 for cfDNA in plasma and serum, respectively—this was further increased to 0.84 by the combination of cfDNA and hemoglobin. Within the group of multiple trauma patients, cfDNA levels were significantly higher in more severely injured patients and patients with severe traumatic brain injury (GCS ≤ 8 versus GCS > 8). Thirteen (20.3%) of the multiple trauma patients died during the first week after trauma. Levels of cfDNA were significantly higher in non-surviving patients than in survivors (p < 0.001), reaching an AUC of 0.81 for cfDNA in both, plasma and serum, which was further increased by the combination with hemoglobin and leukocytes. Conclusions: cfDNA is valuable for estimation of trauma severity and prognosis of trauma patients. [ABSTRACT FROM AUTHOR]

Objective: The distal tibiofibular syndesmosis (DTS) is a fretting joint and it is still a hot issue how to satisfy strong internal fixation while allowing fretting. This study described and evaluated a new method for elastic fixation of DTS injury with Nice Knot. Methods: The study was designed as a retrospective study. Between June 2020 and June 2021, 31 patients who were diagnosed with ankle fracture and DTS injury without additional orthopedic injuries were enrolled in this case series. The study included 22 males and nine females, with an average age of 34.71 ± 14.66 years. All patients were treated with Nice Knot binding for DTS. Surgical time, length of stay, time of DTS fixation, total weight‐bearing time, complications, imaging parameters, and functional scores at follow‐up were recorded. Paired sample t‐tests or single factor analyses of variance were used at intra‐group comparison. Results: All patients completed surgery with normal syndesmotic parameters. The recovery of DTS injury was verified by Hook and lateral malleolus rotation tests. The average follow‐up time was 15.97 ± 3.30 months. Only one case showed superficial infection after surgery, and the wound healed after symptomatic treatment. In terms of imaging, there were no significant differences in tibiofibular clear space (TFCS), tibiofibular overlap distance (TFOS), medial clear space (MCS), and superior clear space (SCS) immediately and at different follow‐up points after surgery. All obtained excellent and good outcomes according to the AOFAS score at least follow‐up after surgery. Conclusions: Nice Knot elastic fixation of DTS injury is firm and stable while maintaining the physiological micromotion of the ankle joint. [ABSTRACT FROM AUTHOR]

Objective: Enhanced recovery after surgery (ERAS) has been successfully adopted for the improvement of medical quality and efficacy in many diseases, but the effect thereof for ankle fracture patients can vary. The aim of the present study was to explore the short‐term postoperative outcomes of ERAS among ankle fracture patients. Methods: The present study was a retrospective cohort study conducted between January 2019 and May 2019. One hundred and sixty ankle fracture participations (58 males and 102 females, aged 41.71 ± 14.51 years) were included. The participants treated with open reduction and internal fixation were divided into two groups (non‐ERAS vs. ERAS) depending on whether ERAS was applied. Postoperative outcomes included American Orthopedic Foot and Ankle Society (AOFAS) score, length of stay (LOS), hospital cost, complications, and consumption of opioids. To assess the association between the groups and outcomes, generalized estimating equation (GEE) modeling and multivariable linear regression analysis were performed. Results: The average follow‐up periods of the participations were 24 months postoperatively. No significant differences were detected between the non‐ERAS group and ERAS group with respect to the demographic of patients in terms of gender, age, Danis‐Weber classification of fracture, dislocation of ankle joint, and comorbidity (P > 0.05). Significant differences in terms of a higher AOFAS score were found in the ERAS group compared with the non‐ERAS group (6.73, 95% CI, 5.10–8.37, p < 0.001) at 3 months postoperatively (PO3M) and (4.73, 95% CI, 3.02–6.45, p < 0.001) at 6 months postoperatively (PO6M). However, similar AOFAS scores were found at 12 months postoperatively (PO12M) (0.28, 95% CI, −0.32 to 0.89, P > 0.05) and at 24 months postoperatively (PO24M) (0.56, 95% CI, −0.07 to 1.19, P > 0.05). Additionally, the GEE analysis and group‐by‐time interaction of AOFAS score revealed that the ERAS protocol could facilitate faster recovery for ankle fracture patients, with higher PO3M and PO6M (both P < 0.05). At the same time, significant differences in terms of a shorter length of stay (−3.19, 95% CI, −4.33 to −2.04, P < 0.01) and less hospital cost (−6501.81, 95% CI, −10955.21 to −2048.42, P < 0.01) were found in the ERAS group compared with the non‐ERAS group. Conclusion: By reducing LOS and hospital cost, the ERAS protocol might improve the medical quality and efficacy. The present study can provide a realistic evaluation and comparison of the ERAS protocol among ankle fracture patients, and ultimately guide clinical decision making. [ABSTRACT FROM AUTHOR]

Objective: To explore the curative effect of buttress plate and traditional internal fixation in the treatment of ankle fracture, so as to provide potential reference for the clinical treatment of this disease. Methods: This is a clinical comparative study. The subjects of this study were one hundred patients with ankle fracture treated in Mindong Hospital Affiliated to Fujian Medical University from January 2019 to December 2021. Enrolled patients were randomly divided into the control group and the experimental group. Patients in the control group were treated with traditional internal fixation, and those in the experimental group were provided with buttress plate. Patients were compared in several aspects such as the comprehensive quality of life assessment questionnaire (GQOLI-74), Baird-Jackson score and postoperative complications. Results: The experimental group showed improved Baird-Jackson score after treatment, significantly higher fracture healing rate than that of the control group three months after treatment. Besides, there was no significant difference in the complications between the two groups, with good prognosis after timely treatment. Conclusion: Internal fixation with buttress plate has obvious advantages in the treatment of ankle fractures, which can effectively improve the quality of life and promote the rapid healing of fractures. It is worthy of clinical promotion and application. [ABSTRACT FROM AUTHOR]

Introduction: Only 6.4–17% of the load is transmitted through the fibula when weight-bearing. Plate fixation of distal fibular fractures using minifragments (≤ 2.8 mm) could lead to similar reduction with less implant removal (IR) rates, compared to small-fragment plates (3.5 mm). We hypothesized that the use of minifragment plates is at least similar in unscheduled secondary surgery. Materials and methods: In this retrospective cohort study, all patients with surgically treated distal fibular fractures between October 2015 and March 2021 were included. Patients treated with plate fixation using minifragments and patients treated with small-fragment plates were compared regarding the following outcomes: secondary dislocation, malreduction, implant malposition, nonunion, surgical site infections (SSI) and IR. Results: Sixty-five patients (54.2%) received a minifragment implant (≤ 2.8 mm) and 55 patients (45.8%) received a small-fragment implant (3.5 mm). There were no patients needing secondary surgery in the minifragment group compared to 9 patients following fixation using small-fragment implants (3 with secondary dislocation, 5 with malreduction and 1 with malposition, p = 0.001). SSI rates were 3.1% for minifragment and 9.1% for small-fragment implants (p = 0.161). Implant removal was performed significantly less often following use of minifragment implants (17.8% and 53.2%, p < 0.001). Conclusions: In this cohort, minifragment plate fixation for distal fibular fractures is an adequate fixation method offering stable fixation with significant lower need for implant removal and comparable complications to small-fragment plates, although an adequately powered randomized controlled study is needed for implementation in a clinical setting. Level of evidence: Therapeutic, III. [ABSTRACT FROM AUTHOR]

Objectives: In patients with rotational ankle fracture, we compare the rate of venous thromboembolism development between patients who received chemoprophylaxis vs those patients that received none. Design: Retrospective cohort study. Setting: Level I trauma center. Patients/participants: Between 2014 and 2018, we identified 483 patients with rotational ankle fracture that had no VTE risk factors, were under 70 years of age, and had an isolated injury. Intervention: Chemoprophylaxis vs no chemoprophylaxis after open reduction internal fixation of a rotational ankle fracture. Main outcome measurements: Development of VTE was the primary outcome. Secondary outcomes included wound problems, infection, hematoma, or non-union. Results: There were 313 patients that received no prophylaxis and 170 patients that received chemoprophylaxis after operative fixation of an isolated ankle fracture. Demographics including age, gender, body mass index, and ASA class were similar between groups. The rate of DVT/PE was 3.5% in those without DVT prophylaxis, and 4.1% in those on DVT prophylaxis with no significant differences found (p = 0.8). There was no significant difference in wound complication (no VTE prophylaxis—3.7% vs VTE prophylaxis—2.5%, p = 0.7) or infection rates (no VTE prophylaxis—3.8% vs VTE prophylaxis 4.1%, p = 1.0) between groups. Conclusions: No difference was detected in the rate of symptomatic DVT or PE in patients based on chemoprophylaxis. Our results support the conclusion that the use of chemoprophylaxis may remain surgeon preference and based on patient risk factors for VTE development. Level of evidence: Level III—retrospective cohort study. [ABSTRACT FROM AUTHOR]

• Fracture-related infection (FRI) was confirmed in 87 (9%) of 1004 patients surgically treated for ankle fractures. • The consensus definition of FRI and its diagnostic algorithm facilitate a systematical diagnostic approach to patients with signs of infection after ankle fracture surgery. • Adequate bacterial sampling of patients with suspected FRI is paramount. Surgical treatment of ankle fractures comes with a substantial risk of complications, including infection. An unambiguously definition of fracture-related infections (FRI) has been missing. Recently, FRI has been defined by a consensus group with a diagnostic algorithm containing suggestive and confirmatory criteria. The aim of the current study was to report the prevalence of FRI in patients operated for ankle fractures and to assess the applicability of the diagnostic algorithm from the consensus group. Records of all patients with surgically treated ankle fractures from 2015 to 2019 were retrospectively reviewed for signs of postoperative infections. Patients with suspected infection were stratified according to confirmatory or suggestive criteria of FRI. Rate of FRI among patients with confirmatory and suggestive criteria were calculated. Suspected infection was found in 104 (10%) out of 1004 patients. Among those patients, confirmatory criteria were met in 76/104 (73%) patients and suggestive criteria were met in 28/104 (27%) at first evaluation. Patients with clinical confirmatory criteria (N = 76) were diagnosed with FRI. Patients with suggestive criteria were further examined with either bacterial sampling at the outpatient clinic, revision surgery including bacterial sampling, or a wait-and-see approach. Eleven (39%) of the 28 patients had positive cultures and were therefore diagnosed as having FRI at second evaluation. In total 87 (9%) patients were diagnosed with FRI according to the consensus definition. Only 73 (70%) of the 104 patients with suspected FRI had adequate bacterial sampling. The prevalence of FRI, applying the FRI-consensus criteria, for patients with surgically treated ankle fractures was 9%. Twenty-two percent of patients who met the confirmatory criteria had negative bacterial cultures. The current study shows that we did not have a systematic approach to patients with suspected FRI as recommended by the consensus group. A systematic approach to adequate bacterial sampling when FRI is suspected is paramount. The consensus definition of FRI and its diagnostic algorithm facilitates such an approach.

Purpose: During study of anatomy of a fractured posterior malleolus of the ankle on CT scans, the authors noticed a prominent crest on the lateral malleolus, which they termed the lateral malleolar crest (LMC). As, in their view, LMC is a clinically important structure which was only briefly mentioned by a few authors without an official term, they focused on the anatomy of this structure. Materials and methods: A total of 352 dry fibulae were analyzed and the following parameters recorded: (F) length of the fibula, (LMC) total length of LMC, (A) length of the part of the examined crest from the superior border of the articular facet of the lateral malleolus (AFLM) to its most proximal intersection with the midline of the fibula, (B) height of the medial triangular rough surface, and (A/F) A/F ratio. Results: The crest was observed in all specimens. (F) was 346.5 ± 26 mm (95% confidence interval [CI] 344–349), (LMC) was 85.4 ± 11.6 mm (95% CI 84.2–86.6), (A/F) was 25% ± 3% (95% CI 24.7–25.3) in the whole group. (A) was 25.9 ± 6.5 mm (95% CI 24.8–26.8) in the whole group, (B) was 34.9 ± 4.7 mm (95% CI 34.3–35.5) in the whole group, 36 ± 6.1 mm (95% CI 35.1–36.9). Conclusion: LMC is an important structure on the lateral malleolus. The knowledge of its anatomy is essential for placement of syndesmotic screws or/and the fibular plate. [ABSTRACT FROM AUTHOR]

Rotational ankle fractures are one of the most common injuries of lower limbs treated by orthopedic surgeons. Open reduction and internal fixation (ORIF) is considered a gold standard treatment for unstable ankle fractures, though adjunct ankle arthroscopy is being increasingly used in cases of ankle trauma. Although the role and use of ankle arthroscopy are expanding, the clinical outcomes and cost-effectiveness of arthroscopy remain undefined. Furthermore, despite the number of clinical research studies performed on arthroscopically assisted surgery for ankle fractures, no definite guidelines have been agreed, and no consensus has been reached regarding indications. This article reviews the role, indications, operative techniques, and complications of ankle arthroscopy and compares the clinical outcomes of conventional ORIF and arthroscopically assisted ORIF.

Introduction: COVID-19 pandemic has disrupted educational activities since 2020. AO Trauma Latin American courses took place in a blended modality during 2021 and participant's feedback was positive. In this study, we aim to identify if there was any difference in learning, planning, and executing an osteosynthesis on a bone model with synchronous or asynchronous faculty support during an online asynchronous learning program. Material and methods: we designed an online asynchronous course designed for teaching about trimalleolar ankle fractures. We randomized twenty participants into two groups: the control group had synchronous faculty support and the intervention group had asynchronous faculty support. Participants were evaluated with initial and final quizzes, preoperative planning, and execution of an osteosynthesis on a bone model. Comparisons of scores between CG and IG were performed using the Mann-Whitney U test for nonparametric variables. A two-tailed p < 0.05 was considered statistically significant. Results: we did not find a significant difference between synchronous or asynchronous faculty support during our asynchronous learning program in quiz results, preoperative planning, global rating scale or the result of the osteosynthesis as compared to the preoperative plan. Conclusion: there appears to be no difference in participant learning with synchronous or asynchronous faculty support during an online, asynchronous course. Asynchronous activities appear to be effective teaching methods and should be considered in continuous medical education in orthopedics. Larger studies are needed to identify differences in participant learning outcomes between synchronous and asynchronous faculty support models. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To investigate trends in incidence rates (IRs) at various fracture sites for patients with type 1 diabetes and type 2 diabetes compared with patients without diabetes in Denmark in 1997–2017. RESEARCH DESIGN AND METHODS: Patients aged ≥18 years with a vertebral, hip, humerus, forearm, foot, or ankle fracture between 1997 and 2017 were identified from Danish hospital discharge data. IRs per 10,000 person-years were calculated over the study period. Median IRs for the first (1997–2001) and the last (2013–2017) 5 years were compared. We used Poisson models to estimate age-adjusted IR ratios (IRRs) of fractures among patients with type 1 and type 2 diabetes versus patients without diabetes. RESULTS: Except for foot fractures, fracture IRs were higher in patients with type 1 or type 2 diabetes compared with patients without diabetes. Hip fracture IRs declined between the first and last 5 years by 35.2%, 47.0%, and 23.4% among patients with type 1, type 2, and without diabetes, respectively. By contrast, vertebral fracture IRs increased 14.8%, 18.5%, 38.9%, respectively. While age-adjusted IRRs remained elevated in patients with type 1 diabetes compared with patients without diabetes, IRRs in patients with type 2 diabetes converged with those observed in patients without diabetes. CONCLUSIONS: Unadjusted fracture rates are higher in patients with diabetes but have decreased between 1997 and 2017 except for vertebral fractures, which increased in all groups. Fracture rates change after age adjustment. [ABSTRACT FROM AUTHOR]

Ankle fracture is a common injury, and depending on injury severity, treatment may be a support boot, cast or surgery. Older people, particularly those with severe injuries who are asked to restrict weight bearing, struggle with early recovery. To elicit older peoples' experience of recovery 6 months after injury, we drew on a phenomenological approach using interviews. Findings revealed that getting on with life was a way of accepting what it feels like to 'be vulnerable', needing to 'be safe' while determinedly working hard to 'be myself'. Being vulnerable identified endurance of inactivity, loneliness and dependency in the non-weight bearing period of recovery, followed by a struggle to weight bear while lacking confidence and being fearful of falling and causing further damage. Being safe conveyed fragility where sensations, pain and stiffness acted as bodily reminders of injury. Lack of function and awareness of danger led to carefulness where planning or curtailing of activities ensured their safety. Being myself showed a determination to push away from a disrupted self-identify of being older or disabled while being challenged by the continuous process of learning to be more mobile. A lack of readiness for old age created a drive to age well. Despite loss of ability, participants hoped to regain their pre-injury way of living. This study challenges practice that disregards the hard work required to recover from ankle fracture. As comorbidity increases with age, failure to consider this aspect may contribute to frailty in this group of older people. [ABSTRACT FROM AUTHOR]

A 15-year-old multisport athlete with chronic left ankle pain and instability 2 years following initial injury was diagnosed with an unstable osteochondral fracture of the lateral talar dome, osteochondritis dissecans, and lateral ligament instability. The patient underwent open surgical repair consisting of loose body excision, lateral ligament reconstruction, and talar dome debridement and microfracture followed by postoperative therapeutic exercise for 7 months. The patient successfully returned to competitive sports within a calendar year. Although not considered particularly rare among adult populations, osteochondral fracture of the talus is relatively rare in adolescents. This case demonstrates that a diagnosis of unstable osteochondral fracture and/or gross lateral ligament instability should be considered in cases involving adolescent athletes with significant ankle injury and prolonged pain and/or loss of function.

Background: Health disparities related to concussions have been reported in the literature for certain minority populations. Given the significant impact of concussions on long‐ and short‐term function, the mitigation of barriers to accessing care is an important public health objective. Objective: To determine if racial and ethnic disparities exist in patients who seek care for concussions compared to a control group with orthopedic ankle injuries (sprains and fractures) to minimize confounding factors that predispose to injury. Design: Cohort study. Setting: Single institution between February 2016 and December 2020. Patients: A retrospective review of electronic medical records was completed for patients with International Classification of Diseases, Tenth Revision (ICD‐10) diagnosis codes for concussion, ankle sprain, and ankle fracture. A total of 10,312 patients were identified: 1568 (15.2%) with concussion, 4871 (47.3%) with ankle sprain, and 3863 (37.5%) with ankle fracture. Interventions: Patients were stratified by demographic factors, including sex, ethnicity, race, and insurance type. Main Outcome Measures: Diagnosis of concussion. Results: The concussion group was the youngest (28.3 years ± 18.0) and had the fewest females (53.1%) compared to the ankle sprain (35.1 years ± 19.7; 58.7%) and fracture groups (44.1 years ± 21.3; 57.3%). The concussion group had a smaller proportion of Hispanic patients than the ankle sprain group (odds ratio [OR] 0.71, 95% confidence interval [CI] 0.55–0.92, p =.010) and fracture group (OR 0.58, 95% CI 0.44–0.75, p = <.001). In addition, the concussion group was less likely to be Asian (OR 0.70, CI 0.52–0.95, p =.023) than the sprain group and less likely to be Black/African American than both sprain (OR 0.65, 95% CI 0.46–0.93, p =.017) and fracture groups (OR 0.62, 95% CI 0.43–0.89, p =.010). There were no differences across racial groups between ankle sprains and fractures. Patients with Medicaid/Medicare and self‐pay had a higher likelihood of being in the concussion group than those with private insurance. Conclusion: Differences in concussion diagnosis may exist between certain demographic groups compared to those with ankle injuries. Efforts to mitigate disparities in concussion care are worthwhile with a focus on patient and caregiver education. [ABSTRACT FROM AUTHOR]

Purpose: A single-injection nerve block provides excellent analgesia in a short time, but rebound pain after the nerve block disappears has attracted researchers' attention. The aim of this study is to evaluate the effect of intravenous dexamethasone on rebound pain after adductor canal block (ACB) and popliteal sciatic nerve block in patients with ankle fracture. Methods: We recruited 130 patients with ankle fractures scheduled for open reduction and internal fixation (ORIF), each of whom received ACB and popliteal sciatic nerve block. Patients were divided into two groups: C (ropivacaine only) and IV (ropivacaine with intravenous dexamethasone). The primary outcome was the incidence of rebound pain. Secondary outcomes included the following: pain scores at 6 h (T1), 12 h (T2), 18 h (T3), 24 h (T4), and 48 h (T5) after operation; duration of the nerve block; number of presses of the analgesia pump and rescue analgesic consumption in the three-day postoperative period; quality of recovery scale (QoR-15 score); postoperative sleep quality; satisfaction of patients; and levels of serum inflammatory markers (IL-1β, IL-6, and TNF-α) six hours after surgery. Results: Compared with group C, the incidence of rebound pain in group IV was significantly reduced, and the duration of nerve block was extended by approximately nine hours (P< 0.05). Moreover, patients in group IV had significantly lower pain scores at T2-T4, lower levels of serum inflammatory markers (IL-1β, IL-6, and TNF-α), higher QoR-15 score two days after the operation, and satisfactory sleep quality the night after surgery (P< 0.05). Conclusion: Intravenous dexamethasone can reduce the rebound pain after adductor block and sciatic popliteal nerve block in patients with ankle fracture surgery, prolong the duration of nerve block, and improve the quality of early postoperative recovery.

To determine whether existing exercise therapies can restore the joint position sense (JPS) deficits of patients with chronic ankle instability (CAI) when compared with controlled non-training patients. Seven databases were searched using ankle, injury, proprioception, and exercise-therapy-related terms. Peer-reviewed human studies in English that used the absolute errors score of joint position reproduction (JPR) test to compare the JPS of injured ankles in CAI patients before and after exercise therapy and non-training controls were included and analyzed. Demographic information, sample size, description of exercise therapies, methodological details of the JPR test, and absolute error scores were extracted by two researchers independently. Meta-analysis of the differences in JPS changes (i.e., absolute errors after treatment minus the baseline) between the exercise therapies and non-training controls was performed with the weighted mean difference (WMD) and 95% confidence interval (CI). Seven studies were finally included. Meta-analyses revealed significantly higher improvements in passive JPS during inversion with, WMD 1.54 and eversion, of, WMD 1.80, after exercise therapies when compared with non-training controls. However, no significant changes in the impaired side active JPS were observed with regard to inversion and eversion. Existing exercise therapies may have a positive effect on passive JPS during inversion and eversion, but do not restore the active JPS deficits of injured ankles in patients with CAI when compared with non-training controls. Updated exercise components with a longer duration that focus on active JPS with longer duration are needed to supplement the existing content of exercise therapies. [ABSTRACT FROM AUTHOR]
