Background: The purpose of this study was to investigate whether decision-making regarding implant selection affects the reimbursement margins for the surgical fixation of ankle fractures. Methods: All ankle fractures treated between 2010 and 2017 within a single-insurer database were identified via Current Procedural Terminology codes by review of electronic medical record. Implant cost was determined via the implant record cross-referenced with the single contract institutional charge master database. The Time-Driven Activity-Based Costing (TDABC) technique was used to determine the costs of care during all activities throughout the 1-year episode of care. Statistical analysis consisted of multiple linear regression and goodness-of-fit analyses. Results: In all, 249 patients met inclusion criteria. Implant costs ranged from $173 to $3944, averaging $1342 ± $751. The TDABC-estimated cost of care ranged from $1416 to $9185, averaging $3869 ± $1384. Finally, the total reimbursed cost of care ranged between $1335 and $65 645, averaging $13 954 ± $9445. The implant costs occupied an estimated 34.7% of the TDABC-estimated cost of care per surgical encounter. Implant cost, as a percentage of the overall TDABC, was estimated as 36.2% in the inpatient setting and 33% in the outpatient setting, which was the second highest percentage behind surgical costs in both settings. We found a significant increase in net revenue of $1.93 for each dollar saved on implants in the outpatient setting, whereas the increase in net revenue per dollar saved of $1.03 approached significance in the inpatient setting. Conclusion: There is a direct relationship between intraoperative decision-making, as evidenced by implant choices, and the revenue generated by surgical fixation of ankle fractures. Intraoperative decision-making that is cognitive of implant cost can facilitate adoption of institutional cost containment measures and prompt increased healthcare value.

Background: Ankle fractures are a common injury treated by orthopaedic surgeons. Unstable, displaced ankle fractures are often fixed with open reduction internal fixation (ORIF) using different implant constructs at various cost. No study to date has looked at transparency in ankle implant costs to surgeon behavior. Our surgeons self-identified that the biggest barrier for lowering implant cost was the lack of cost transparency. This was a surgeon-led-study to evaluate whether increased transparency in implant costs affected surgeon behavior. Methods: Monthly operative logs from December 2021 to September 2022 were reviewed at our level 1 trauma center for operative fixation of ankle fractures. The cost data of each fixation construct was reported to trauma-trained surgeons at the end of each month from March 2022 to June 2022. Average costs of implants were compared before and after education. A linear mixed model was used to explore what factors were associated with changes in costs. Surgeons also participated in a poststudy survey. Results: The implant costs of 110 ankle fracture fixations were reviewed over the period before education (n = 60), during education (n = 30), and after education (n = 20). The mean implant cost difference for unimalleolar fractures was -$204.80 (P = .68), whereas the mean cost difference for bimalleolar fractures was -$9.82 (P = .98). Trimalleolar fractures had a mean cost difference of +$94.47 (P = .84). Linear mixed model demonstrated fracture pattern as the only factor significantly associated with implant costs (P < .01). Post-education surgeon survey revealed that 6 of 7 surgeons felt that monthly updates affected their implant selection. However, only 2 surgeons demonstrated a change in practice with decreased implant costs during the study. Conclusion: The majority of surgeons self-reported being influenced by the implant cost education, but the detected change in implant cost was only observed in less than one-third of surgeons. Our results suggest implant selection and related costs are not influenced by increased cost transparency education alone. [ABSTRACT FROM AUTHOR]

Background: Given the increasing accessibility of Internet access, it is critical to ensure that the informational material available online for patient education is both accurate and readable to promote a greater degree of health literacy. This study sought to investigate the quality and readability of the most popular online resources for ankle fractures. Methods: After conducting a Google search using 6 terms related to ankle fractures, we collected the first 20 nonsponsored results for each term. Readability was evaluated using the Flesch Reading Ease (FRE), Flesch-Kincaid Grade Level (FKGL), and Gunning Fog Index (GFI) instruments. Quality was evaluated using custom created Ankle Fracture Index (AFI). Results: A total of 46 of 120 articles met the inclusion criteria. The mean FKGL, FRE, and GFI scores were 8.4 ± 0.5, 57.5 ± 3.2, and 10.5 ± 0.5, respectively. The average AFI score was 15.4 ± 1.4, corresponding to an "acceptable" quality rating. Almost 70% of articles (n = 32) were written at or below the recommended eighth-grade reading level. Most articles discussed the need for imaging in diagnosis and treatment planning while neglecting to discuss the risks of surgery or potential future operations. Conclusion: We found that online patient-facing materials on ankle fractures demonstrated an eighth-grade average reading grade level and an acceptable quality on content analysis. Further work should surround increasing information regarding risk factors, complications for surgery, and long-term recovery while ensuring that readability levels remain below at least the eighth-grade level.

Wound complications after surgery for ankle fractures can lead to catastrophic consequences. The purpose of this study was to evaluate the risk factors of postoperative wound complications in patients with ankle fracture and to determine their effects on prognosis. 200 patients with ankle fracture treated in our hospital from October 2021 to December 2023 were analysed retrospectively. The total incidence of postoperative wound complications was 19% (38/200). Type of complications: wound edge necrosis 15 cases (39.47%), dehiscence (reopening of wound) 13 cases (34.21%), delayed healing (>30 days) 10 cases (26.32%); Univariate analysis showed that patients' age, body mass index (BMI), current smoking, alcoholism, diabetes mellitus, injury mechanism, open fracture, wound classification, higher American Society of Anesthesiologists (ASA) score and operation time were all associated with postoperative wound complications. Multivariate Logistic regression model shows: age ≥60 years old OR3.671 (1.875–5.937), BMI OR1.198 (1.143–1.324), current smoking OR2.727 (1.251–5.602), alcoholism OR1.143 (1.034–1.267), complicated with diabetes OR2.763 (1.236–4.852), injury mechanism (high vs. low and medium energy) OR2.437 (1.238–4.786), open fracture OR1.943 (1.8262.139), wound classification (II vs. I) OR4.423 (1.73511.674), ASA score (III–IV vs. I–II) OR1.307 (1.113–2.194) was an independent risk factor for postoperative wound complications in patients with ankle fracture. Further, ROC curves showed that these nine independent influences had high accuracy and validity in predicting postoperative wound complications in patients with ankle fractures. In conclusion, independent risk factors for postoperative complications of ankle fracture were age >60 years, BMI, injury mechanism, open fracture, wound classification (II vs. I), ASA score, current smoking, and alcoholism. The wound classification (II vs. I) has the highest diagnostic value. [ABSTRACT FROM AUTHOR]

Surgical site infections (SSIs) following ankle fracture fixation pose significant challenges in patient recovery and healthcare management. Identifying risk factors contributing to SSIs can aid in developing targeted prevention and treatment strategies. This systematic review and meta‐analysis were conducted according to the PRISMA guidelines and the PICO framework. A comprehensive literature search across major databases, including PubMed, Embase, Web of Science and the Cochrane Library, was completed on September 26, 2023. The inclusion criteria encompassed peer‐reviewed studies of various designs that investigated risk factors for SSIs post‐ankle fracture fixation. Quality assessment was performed using the Newcastle‐Ottawa Scale. Statistical analyses assessed heterogeneity and calculated combined effect sizes using fixed‐ or random‐effects models, depending on the heterogeneity observed. The initial search yielded 1250 articles, with seven meeting the inclusion criteria after rigorous screening and full‐text review. The included studies, conducted between 2006 and 2019, predominantly utilized case–control designs. The meta‐analysis identified diabetes, open fractures, smoking, age, alcohol consumption, ASA score ≥3, high BMI, contaminated incisions, fracture dislocation and heart disease as significant risk factors for postoperative SSIs. Publication bias assessment showed no significant bias across studies. The identification of key risk factors such as diabetes, open fractures, smoking, advanced age, alcohol consumption, high ASA score, elevated BMI, contaminated incisions, fracture dislocation and heart disease is essential in managing SSIs post‐ankle fracture fixation. Targeted interventions addressing these risk factors are crucial to reduce the incidence of SSIs and improve overall patient outcomes. [ABSTRACT FROM AUTHOR]

This study was designed to identify risk factors for wound complications including surgical site infection (SSI) and wound healing issues following open reduction and internal fixation (ORIF) of ankle fractures. A retrospective analysis of individuals with ankle fractures treated with ORIF was undertaken. Study subjects were divided into a wound complications (WC) group and a no wound complication (NWC) group. The WC group was further divided into an SSI group and wound healing issues group. Twenty‐one potential risk factors associated with wound complications after ORIF were tracked. Uni‐ and multivariate binary logistical regression analyses were used to identify risk factors associated with wound complications, ISS and wound healing issues. In total, 613 individuals, who had undergone surgery for ankle fractures formed the study cohort. The incidence of postoperative wound complications was 10.3% (63 cases), including 5.2% of SSI (32 cases) and 5.1% of wound healing issues (31 cases). The independent risk factors for wound complications were age 65 years or older, preoperative serum albumin level below 35 g/L, peripheral neuropathy, open fracture, fewer than seven cases per year in surgical volume, and attending surgeon level. The independent risk factors for SSI were age 65 years or older, preoperative serum albumin level below 35 g/L, open fracture and fewer than seven cases per year in surgical volume. The independent risk factors for wound healing issues were preoperative serum albumin level below 35 g/L, peripheral neuropathy, open fracture and attending surgeon level. Herein we found both factors inherent to the injury and individual and those pertaining to the surgical team affected the frequency of wound complications after ORIF of ankle fractures. Specifically, advanced age and low surgical volume were associated with a greater risk of SSI. Peripheral neuropathy and the low expertise level on the part of the surgeon were associated with a greater risk of wound healing issues. Hypoproteinaemia and open fracture were both associated with a greater risk of both SSI and wound healing issues. [ABSTRACT FROM AUTHOR]

Background: Wagstaffe fracture constitutes an indirect injury to the AITFL and can precipitate syndesmotic instability. The prevailing fixation methods often involve the use of mini-screws or K-wires, with absorbable suture repair reserved for cases with small or comminuted fragments exhibiting instability. In this study, we devised a mini-plate fixation method capable of securing the fracture fragment irrespective of its size or condition. Methods: A retrospective chart review was conducted on patients who underwent surgery for ankle fractures between May 2022 and October 2023. The surgical technique involved direct fixation of the Wagstaffe fracture using mini-plate fixation. Radiologic evaluation was performed using postoperative CT images, and clinical outcomes were assessed using the OMAS and VAS. Results: Fourteen patients with an average age of 62.5 years were included. Most fractures were associated with the supination-external rotation type. The average preoperative OMAS significantly improved from 5.95 to 83.57 postoperatively. The average VAS score decreased from 7.95 preoperatively to 0.19 postoperatively. Conclusions: The mini-plate technique for Wagstaffe fractures exhibited dependable fixation strength, effective fracture reduction, a minimal complication rate, and judicious surgical procedure duration.

Introduction: Patients recovering from musculoskeletal trauma have a heightened risk of opioid dependence and misuse, as these medications are typically required for pain management. The purpose of this meta-analysis was to examine the association between fracture type and chronic opioid use following fracture fixation in patients who sustain lower extremity trauma. Materials and Methods: A meta-analysis was performed using PubMed and Web of Science to identify articles reporting chronic opioid use in patients recovering from surgery for lower extremity fractures. 732 articles were identified using keyword and MeSH search functions, and 9 met selection criteria. Studies were included in the final analysis if they reported the number of patients who remained on opioids 6 months after surgery for a specific lower extremity fracture (chronic usage). Logistic regressions and descriptive analyses were performed to determine the rate of chronic opioid use within each fracture type and if age, year, country of origin of study, or pre-admission opioid use influenced chronic opioid use following surgery. Results: Bicondylar and unicondylar tibial-plateau fractures had the largest percentage of patients that become chronic opioid users (29.7–35.2%), followed by hip (27.8%), ankle (19.7%), femoral-shaft (18.5%), pilon (17.2%), tibial-shaft (13.8%), and simple ankle fractures (2.8–4.7%).Most opioid-naive samples had significantly lower rates of chronic opioid use after surgery (2–9%, 95% CI) when compared to samples that allowed pre-admission opioid use (13–50%, 95% CI). There were no significant associations between post-operative chronic opioid use and age, year, or country of origin of study. Conclusions: Patients with lower extremity fractures have substantial risk of becoming chronic opioid users. Even the lowest rates of chronic opioid use identified in this meta-analysis are higher than those in the general population. It is important that orthopedic surgeons tailor pain-management protocols to decrease opioid usage after lower extremity trauma. [ABSTRACT FROM AUTHOR]

Background: Evaluating the predictors of unfavorable outcomes in patients with ankle fractures is crucial for identifying high-risk patients and implementing personalized treatment strategies. This study aimed to analyze factors that influence quality of life in patients with ankle fractures. Methods: Four databases were consulted. The main outcomes were functionality and quality of life scales combined using the standard mean difference (SMD) (Review Manager 5.4). Results: Eight studies with 2486 patients were included. A significant correlation was found between female sex and worse functionality scores (beta 4.15, 95% CI 1.84–6.46). Additionally, older age was correlated with worse functionality scores (beta −0.24, 95% CI −0.29 to −0.19). Patients with diabetes or metabolic syndrome also had worse outcomes (SMD 0.27, 95% CI 0.18–0.36). High BMI and obesity were also associated with worse quality of life scores (beta 2.62, 95% CI 0.77–4.48). Smokers had greater disability in the analyzed scales (SMD 0.22, 95% CI 0.05–0.39). No significant differences were observed with respect to syndesmotic involvement. Conclusions: Age, sex, diabetes, high BMI, and smoking negatively impact functional outcomes and quality of life in patients with ankle fractures. [ABSTRACT FROM AUTHOR]

Aim: To facilitate the posterolateral approach to the posterior malleolus patients are often positioned prone initially, then turned supine to complete fixation at the medial malleolus. We sought to define observed differences in the radiographic appearance of implants relative to the joint line, in prone and supine positions. Methods: A 3.5 mm tubular plate and a 3.5 mm posterior distal tibial periarticular plate were applied sequentially to 3 individual cadaveric legs, via a posterolateral approach. The tubular plate was positioned to simulate buttress fixation and the posterolateral plate placed more distally. Each limb was secured on a custom jig and radiographs were taken on a mobile c-arm fluoroscopy machine with a calibration ball. A series of prone AP, supine PA and mortise radiographs were taken. Prone radiographs were also taken in different degrees of caudal tilt to simulate knee flexion which occurs in practice, during intraoperative positioning. Plate tip-joint line distances were measured and Mann–Whitney U tests performed. Results: There was no statistically significant difference in plate tip-joint line distance when comparing equivalent prone and supine views (PA/AP or mortise). However, significant differences in apparent implant position were noted with alterations in caudal tilt. When taking a prone image, when the knee is flexed to 20 degrees, the plate tip will appear 6.5–8.5 mm more proximal than in the equivalent supine image where the knee is extended and the fluoroscopy beam is orthogonal to the anatomic axis of the tibia. Conclusion: Observed differences in radiographic appearance of metalwork in the prone and supine position are most likely due to knee flexion and the resulting variation in the angle of the fluoroscopy beam, rather than projectional differences between supine and prone views. Surgeons should be alert to this when analysing intraoperative images. [ABSTRACT FROM AUTHOR]

Purpose: Ankle fracture fixation is the gold standard of treatment but it does have its own complications. There is inadequate data regarding the comparative effectiveness of early vs. delayed fixation for open ankle fracture outcomes. This study compares the clinical and functional outcomes of open ankle fractures treated by early or delayed definitive fixation and identifies the limitations of both methods. Materials and Methods: All 73 patients enrolled in the study underwent surgical intervention within 24 hours of injury. The early fixation group (group A) consisting of 39 patients underwent definitive fixation as an index procedure, while the delayed fixation group (group B) consisted of 34 patients who underwent debridement and external fixator application as an index procedure and definitive fixation when soft tissue condition was conducive. All patients were evaluated at 2, 6, and 12 weeks postoperatively and then three monthly for a year. Results: Enneking and American Orthopaedic Foot and Ankle Society scores were markedly higher in the early fixation group at 6 months postoperatively (p-values <0.001 and 0.011, respectively). However, no discernible intergroup difference was evident at 12 months postoperatively. Between 6 and 12 months, group functional outcome scores were significantly different. At 6 months, there was a substantial difference in dorsiflexion between the two groups (p-values 0.001 and <0.001, respectively), but no difference was observed at 12 months postoperatively. At 6 and 12 months, group average plantar flexions were non-significantly different. Conclusion: Early definitive fixation of complex ankle fractures using a targeted approach produced promising results for lower grade open fractures (grades 1 and 2), and delayed definitive fixation, after initial external fixation to allow for soft tissue stabilization, produced promising results for higher grade open fractures (grades 3A and 3B). At 12-month follow-ups, clinical and functional outcomes achieved using these strategies were equivalent. [ABSTRACT FROM AUTHOR]

Introduction: Uncertainty regarding the timing of weight bearing following ankle open reduction internal fixation (ORIF) in patients with different ankle fracture patterns remains. Traditional rehabilitation methods, including six weeks of non-weight bearing (NWB), is still a common approach in many hospitals, while some previous evidence has shown immediate weight bearing (IWB) to be beneficial. Method: 32 adult participants with unimalleolar, bimalleolar or trimalleolar ankle fractures and stable fixation following ankle ORIF will be randomly allocated to either Immediate Weight Bearing (IWB) or Delayed Weight Bearing (DWB) groups. Stability of fixation is a subjective assessment made by the operating surgeon at the completion of fixation and is independent of fracture pattern. Participants in the IWB group will be allowed to weight bear as tolerated within 24 h, while participants in the DWB group will remain non-weight bearing for six weeks. Participants’ data including Olerud and Molander Ankle Score, Self-Reported Foot and Ankle Score, SF-36 health survey, time to return to work will be collected. X-rays will be assessed by orthopaedic team members for fixation-related complications including reduction loss, malreduction/malunion, implant failure and non-union. Participants data will be collected at six weeks, three and six-months post-surgery. We will determine the feasibility of a full RCT through assessing the recruitment rate, adherence rate, and drop-out rate. Results: Not applicable.This pilot RCT will endeavour to optimise standard rehabilitation protocols post ankle ORIF.

Aims: Ankle fracture is one of the most common musculoskeletal injuries sustained in the UK. Many patients experience pain and physical impairment, with the consequences of the fracture and its management lasting for several months or even years. The broad aim of ankle fracture treatment is to maintain the alignment of the joint while the fracture heals, and to reduce the risks of problems, such as stiffness. More severe injuries to the ankle are routinely treated surgically. However, even with advances in surgery, there remains a risk of complications; for patients experiencing these, the associated loss of function and quality of life (Qol) is considerable. Non-surgical treatment is an alternative to surgery and involves applying a cast carefully shaped to the patient’s ankle to correct and maintain alignment of the joint with the key benefit being a reduction in the frequency of common complications of surgery. The main potential risk of non-surgical treatment is a loss of alignment with a consequent reduction in ankle function. This study aims to determine whether ankle function, four months after treatment, in patients with unstable ankle fractures treated with close contact casting is not worse than in those treated with surgical intervention, which is the current standard of care. Methods: This trial is a pragmatic, multicentre, randomized non-inferiority clinical trial with an embedded pilot, and with 12 months clinical follow-up and parallel economic analysis. A surveillance study using routinely collected data will be performed annually to five years post-treatment. Adult patients, aged 60 years and younger, with unstable ankle fractures will be identified in daily trauma meetings and fracture clinics and approached for recruitment prior to their treatment. Treatments will be performed in trauma units across the UK by a wide range of surgeons. Details of the surgical treatment, including how the operation is done, implant choice, and the recovery programme afterwards, will be at the discretion of the treating surgeon. The non-surgical treatment will be close-contact casting performed under anaesthetic, a technique which has gained in popularity since the publication of the Ankle Injury Management (AIM) trial. In all, 890 participants (445 per group) will be randomly allocated to surgical or non-surgical treatment. Data regarding ankle function, QoL, complications, and healthcare-related costs will be collected at eight weeks, four and 12 months, and then annually for five years following treatment. The primary outcome measure is patient-reported ankle function at four months from treatment. Anticipated impact: The 12-month results will be presented and published internationally. This is anticipated to be the only pragmatic trial reporting outcomes comparing surgical with non-surgical treatment in unstable ankle fractures in younger adults (aged 60 years and younger), and, as such, will inform the National Institute for Health and Care Excellence (NICE) ‘non-complex fracture’ recommendations at their scheduled update in 2024. A report of long-term outcomes at five years will be produced by January 2027. Cite this article: Bone Jt Open 2024;5(3):184–201.

Introduction The optimal surgical approach for malleolar fractures and distal tibiofibular syndesmotic (DTFS) disruption remains controversial. There is no uniform treatment protocol for this type of injury. The objective was to review modern surgical treatments of the pathology and determine the optimal option. Material and methods Articles of French, English, Uzbek, Kazakh, German, Danish, Japanese and Chinese authors were retrospectively reviewed. An internet search of MedLine; PubMed; Scopus; Web of Science, CINAHL, the Cochrane Central Register of Controlled Trials databases was performed. Results Comparative studies of dynamic fixation and static fixation of the DTFS showed advantages of the dynamic methods enabling precise, anatomical syndesmotic fixation and faster healing. Dynamic fixation methods would require no implant removal, while syndesmotic screw woul be taken off to reduce compression in the ankle joint and minimize a risk of malreduction facilitating mobility of the ankle joint. Dynamic methods are associated with greater stability and less complication rate. However, static methods have the advantages of being more accessible and less expensive, which can be an important factor choosing a treatment method. Static methods are a wide application and can be used in a wide range of clinical cases. Long-term results show no statistically significant differences between dynamic fixation and static fixation. Discussion Literature review indicates the dynamic method with suture-button, a combined method and titanium cable isotonic annular fixation system as the preferred technique for surgical stabilization of distal syndesmosis associated with ankle fractures with a lower risk of postoperative complications and the possibility of short-term rehabilitation. Conclusion The choice between dynamic and static methods of distal syndesmosis fixation depends on many factors, including the complexity of the injury, the availability and cost of implants and the experience of the surgeon.

Purpose: The aim of the study was to follow the influence of the Ergon Technique on proprioception in patients after surgical treatment of bimalleolar ankle fracture. Material/Methods: 30 patients with a bimalleolar fracture in the subacute postoperative period were studied, divided as follows: control group (CG) - 15 patients and experimental group (EG) - 15 patients. In CG, a traditional model of kinesitherapy is applied, and in EG, an experimental model is applied, which includes twice a week and Ergon Technique. To monitor changes in proprioception, a test was conducted: a balanced stance on the injured leg on a hard and flat surface was performed, and the time the patient maintained balance (in seconds) was recorded. Results: The mean values (±SD) after one month of kinesitherapy application are as follows: in the control group 0,9333+0,88 sec. and 3,0 sec. in the experimental group. After three months of treatment, the results are as follows: in the control group, 3,93+2,49 sec. And 9,2+4,19 sec. in the experimental group. The values of P show that the established difference in the mean values ​​of the indicator in the two groups after three months of kinesitherapy is statistically significant and proves a higher efficiency of the experimental model compared to the traditional one applied in the control group at P

A study published in Clinical Orthopaedics and Related Research found that Medicaid insurance is associated with decreased MRI use for ankle sprains compared to private insurance. However, patients with Medicaid were more likely to undergo ankle surgery after receiving an MRI. These findings suggest a correlation between MRI utilization and insurance type, with higher utilization for those with private insurance but lower surgical yield. The study highlights the need to further investigate the disparities related to Medicaid insurance and advanced imaging usage. It also emphasizes the importance of addressing healthcare disparities and improving patient outcomes through factors such as orthopaedic clinical pathway guidelines, policy changes, and financial counseling.

Abstract Background Roughly 10% of fractures in adults are ankle fractures. These injuries are found in both sexes and present with different fracture characteristics. The treatment varies with the patients’ biology and fracture type, and the goals are to restore stability, prevent pain and maintain ankle function. Clinicians generally use outcomes like assessment of radiography, pain level, or function. The use of patient-reported outcome measures is increasing, and the Manchester–Oxford Foot Questionnaire (MOXFQ) has been shown to have good measurement properties when validated in patients with foot and ankle disorders. However, the instrument has not been validated for ankle fracture patients. This study aims to assess the content validity of the items in MOXFQ in surgically treated ankle fracture patients. Methods A qualitative deductive design was used to investigate patients’ response process of the MOXFQ. Individual interviews were conducted using cognitive interviewing based on the theoretical framework of the 4-step model by Tourangeau. Adult patients that were surgically treated for an ankle fracture between four weeks and 18 months were purposively sampled, and interviews followed a semi-structured interview guide. The predetermined categories were comprehension, retrieval, judgement, and response. Results Seventeen respondents (65% females) were interviewed. Respondents’ age ranged from 27 to 76 years. Some of the respondents in the early recovery phase were limited by post-operative restrictions and did not find the items in the walking/standing domain relevant. Respondents that were allowed weight-bearing as tolerated (WBAT) were able to recall relevant information for most items. Respondents with time since surgery more than 12 months had less pain and remembered fewer relevant episodes in the recall period. Items in the social interaction domain contained ambiguous questions and were generally considered less important by respondents. The summary index score lacked important concepts in measuring overall quality of life. Conclusions Pain was a central concept in the post-operative recovery of ankle fracture patients. The MOXFQ-subscales for pain and walking/standing had acceptable content validity in patients that were allowed WBAT. The social interaction-subscale and the summary index score had insufficient content validity for this patient population.

Taurolidine, known for its broad-spectrum antimicrobial properties and low toxicity, has shown promise in reducing infections in various surgical settings. However, it has not been extensively evaluated in orthopedic surgery. This study assessed the efficacy of taurolidine irrigation in reducing surgical site infections in patients undergoing ankle fracture surgery. A retrospective review was conducted for patients >20 years old who underwent ankle fracture surgery between March 2016 and March 2023, with follow-ups exceeding 6 months. Patients were classified into the following two groups: those who underwent normal saline (NS) irrigation and those who underwent taurolidine irrigation. Minor infections were defined as requiring additional oral antibiotics postoperatively, while major infections were characterized by hospitalization or reoperation due to infection within 3 months. Of 844 patients, 688 were included. The taurolidine group (n = 328) had a significant reduction in minor infections (7.3% vs. 22.5%, odds ratio = 0.410, p = 0.028) compared to the NS group (n = 360). Major infections were fewer in the NS group (1.2% vs. 0%, p = 0.051), but the number of cases was too small for reliable analysis. Taurolidine irrigation significantly reduces the occurrence of minor infections in ankle fracture surgeries when compared to normal saline irrigation.

BackgroundPatients with psychiatric comorbidities represent a significant subset of those sustaining pilon fractures. The purpose of this study is to examine the association of psychiatric comorbidities (PC) in patients with pilon fractures and clinical outcomes.MethodsA multi-institution, retrospective review was conducted. Inclusion/exclusion criteria were skeletally mature patients with a tibia pilon fracture (OTA Type 43B/C) who underwent definitive fracture fixation utilizing open reduction internal fixation (ORIF) with a minimum of 24 weeks of follow-up. Patients were stratified into two groups for comparison: PC group and no PC group.ResultsThere were 103 patients with pilon fractures that met the inclusion/exclusion criteria of this study. Of these patients, 22 (21.4%) had at least one psychiatric comorbidity (PC) and 81 (78.6%) did not have psychiatric comorbidities (no PC). There was a higher percentage of female patients (PC: 59.1% vs no PC: 25.9%, p=0.0.005), smokers (PC: 40.9% vs no PC: 16.0%, p=0.02), and drug users (PC: 22.7% vs no PC: 8.6%, p=0.08) amongst PC patients. Fracture comminution (PC: 54.5% vs no PC: 32.1%, p=0.05) occurred more frequently in PC patients. The PC group had a higher incidence of weightbearing noncompliance (22.7% vs 7.5%, p=0.04) and reoperation (PC: 54.5% vs no PC: 29.6%, p=0.03).ConclusionPatients with psychiatric comorbidities represent a significant percentage of pilon fracture patients and appear to be at higher risk for postoperative complication. Risk factors that may predispose patients in the PC group include smoking/substance use, weightbearing noncompliance, and fracture comminution. Level of Evidence: III.

BACKGROUND: Accurate reduction of ankle fractures under direct vision has become a common understanding among foot and ankle surgeons. How to fully expose free or compressed fragments of the posterior ankle remains one of the most challenging problems. OBJECTIVE: To explore the clinical efficiency of the para-Achilles tendon approach in exposing and repositioning the posterior malleolus sandwich fracture. METHODS: A retrospective study was made for 26 patients with posterior malleolus sandwich fracture treated with open reduction and internal fixation via para-Achilles tendon approach from January to December 2020 in The Second People’s Hospital of Dalian. 21 of 26 cases were managed with the lateral approach of Achilles tendon and 5 cases were managed with the medial approach of Achilles tendon. There were 19 males and 7 females, with the age of 24- 69 years, averagely 38.6 years. The operation time and postoperative complications were recorded. The fracture reduction condition was evaluated by Burwell- Charnley imaging standard. Before operation, 3 months after operation and last follow-up, visual analog scale score, ankle plantar flexion and dorsiflexion and American Orthopedic Foot & Ankle Society Ankle Hind Score were used to evaluate the treatment effect. RESULTS AND CONCLUSION: (1) All 26 patients were followed up for an average of 14.6 months (range 13-18 months). The operation time was 52-85 minutes (average 64.2 minutes). (2) Part of the skin edge of the lateral malleolus incision was necrotic in one patient and healed completely after a dressing change. Incision healing of the other patients was in one stage. (3) Through Burwell-Charnley imaging standard, anatomical reductions were obtained in 24 of 26, and good reductions were in 2 of 26, with an excellent and good rate of 100%. (4) At the last follow-up, the visual analog scale score (1.19±0.40) was significantly lower than the preoperative score (6.81±0.80) (P < 0.01). Ankle plantar flexion (33.5±5.02)° and ankle plantar back stretch (17.23±0.99)° were significantly increased compared with preoperative data (14.58±2.50)° and (5.81±1.02)° (P < 0.01). American Orthopedic Foot & Ankle Society Ankle Hind Score was improved to (89.31±3.62) points compared to preoperative (46.00±5.45) points (P < 0.01). The results were excellent in 23 patients and good in 3 patients, with an excellent and good rate of 100%. (5) It is concluded that the open reduction and internal fixation via the para-Achilles tendon approach for the treatment of posterior malleolus sandwich fracture were efficient with decreased operation time, satisfying fracture reduction, fewer complications, satisfactory motion range, and functional recovery.

Introduction: Existing research has established a correlation between post-traumatic mental health conditions, including anxiety and depression, and various aspects of recovery, such as pain exacerbations, reduced functional recovery, and lowered patient satisfaction. However, the influence of pre-existing mental health conditions on orthopaedic trauma outcomes has not been thoroughly investigated. The objective of this study was to systematically review literature addressing the association between pre-existing mental health conditions and patient outcomes following surgical interventions for lower extremity fractures in non-geriatric populations. Methods: A systematic literature review was conducted using Medline, Embase, and Scopus databases following PRISMA-ScR guidelines to select studies that examined lower extremity orthopaedic trauma outcomes in relation to pre-existing mental health conditions. Studies that evaluated patients with surgically treated lower extremity fractures and a history of mental health conditions such as anxiety, depression, or mood disorders were included. Studies with a mean patient age above 65 years of age were excluded to focus on non-geriatric injury patterns. Results: The systematic review identified 12 studies investigating the relationship between surgical outcomes of orthopaedic lower extremity fractures and pre-existing mental health disorders in non-geriatric populations. Studies included patients with pelvis, femur, tibia, and ankle fractures. A majority (83%) of these studies demonstrated that patients with pre-existing mental health diagnoses had inferior functional outcomes, heightened pain levels, or an increase in postoperative complications. Discussion: The presence of pre-existing mental health conditions, particularly anxiety and depression, may predispose orthopaedic trauma patients to an elevated risk of suboptimal functional outcomes, increased pain, or complications after surgical intervention for lower extremity fractures. Future research should focus on interventions that mitigate the impact of mental health conditions on orthopaedic outcomes and patient wellness in this population. [ABSTRACT FROM AUTHOR]

Introduction: The sustentaculum tali is displaced in almost half of calcaneal fractures and during surgical fixation represents one of the main reference points upon which the other bone has to be reduced. The purpose of this study was to investigate which subtalar joint fracture pattern is more frequently associated with sustentaculum tali involvement. Furthermore, correlation between postoperative clinical outcome and sustentaculum tali integrity was performed. Material and methods: Patients with isolated calcaneal fractures were analyzed. Sanders-type fracture and involvement of both sustentaculum tali and calcaneocuboid joint were detected on computed tomography imaging; postoperative AOFAS scores were analyzed according to sustentacular involvement. Results: Fifty calcaneus fractures in 47 patients were included in the final analysis. The sustentaculum tali was fractured in 18 cases (36.0%), thus contradicting its supposed constant position. Sanders type 3 and 4 fractures were more frequently associated with fractured sustentaculum than type 2 (p = 0.012). Sanders type 4 fractures were associated with displaced sustentacular fragment significantly more than type 2 and 3 (p = 0.043). Patients with intact sustentaculum tali reported significantly higher (p < 0.001) mean AOFAS scores than the uninjured group (84.4 ± 9.1 and 74.3 ± 9.5, respectively). Conclusion: Sanders type 3 and 4 fractures were more frequently associated with sustentaculum tali and/or calcaneocuboid joint involvement than simpler fractures. Injury of sustentaculum tali was related to significant worse postoperative clinical outcomes, underlying the relevance of this fragment on clinical course. [ABSTRACT FROM AUTHOR]

Purpose: Patients with surgically treated ankle fractures are traditionally kept non-weightbearing for at least six weeks post-operatively; however, recent literature suggests numerous benefits of early weightbearing (EWB) before six weeks without significantly impacting long-term outcomes. This study aims to review the safety of early vs late weightbearing following ankle fracture fixation by assessing the complication rate. Methods: This was a single-centre retrospective study. Between 2020 and 2023, all ankle fixations that commenced weightbearing at two weeks were added to the EWB group. An equal number of similar patients with six-week non-weightbearing were added to the late weightbearing (LWB) group. Baseline characteristics, risk factors, types of fractures and any complications in the six-month post-operative period were evaluated from these cohorts. Results: In total, 459 ankle fixations were identified of which 87 patients met the criteria for the EWB group, with a further 87 added to the LWB group. There was no significant difference in age between the two groups (51.7 ± 20.1 vs 51.0 ± 15.5, respectively; p = 0.81), but more female patients and diabetics in the EWB group. Fracture types were similar between both cohorts (p = 0.51). Complication rate in the EWB group was not significantly different to the LWB group (5 vs 9, p > 0.05). Conclusion: No increase in complication rate was identified by commencing weightbearing early at two weeks after ankle fixation compared to six weeks. We therefore suggest EWB if appropriate, given its associated benefits including restoration of patient independence and improved quality of life. Level of evidence: Therapeutic, Level IV.

Purpose: To analyze differences in union, complication rates and cost from surgical fixation of distal fibula fractures with fibular plating implants. Methods: In total, 380 adult patients from 2012 to 2015 treated with 12 fibular plates from 4 different manufacturers utilized by 9 surgeons were retrospectively reviewed. They were stratified into a conventional one-third tubular fibular plate group, pre-contoured anatomic locking plate group, or a heterogeneous group including 3.5-mm reconstruction, one-third tubular locking, composite, and limited compression plates. The outcomes included failure of fixation, deep infection requiring debridement, time to union, anatomic reduction, superficial infection, hardware removal, and post-traumatic arthritis. Plate and screw costs were calculated from hospital billing records. Results: Pre-contoured locking plates were used in older, female patients with a greater number of comorbidities. Open injuries and OTA 44B fractures were more likely to be an indication for pre-contoured plates. There was no difference noted in time to union between the different plating groups. Risk factors for deep infection requiring debridement included a history of tobacco use, open fractures, and pre-contoured locking plates relative to the conventional plating group. The pre-contoured plating group was on average $586 more expensive compared to the conventional group. Conclusion: Pre-contoured locking plates achieved similar radiographic outcomes compared to conventional plates with an increased risk of complications and higher cost. Surgeons should consider their choice of implant based on the patient's fracture pattern, underlying comorbidities, and risk for infection. [ABSTRACT FROM AUTHOR]

Aim: This article describes the technique of tibiotalar nailing performed using an antegrade tibial nail for salvage of distal tibia and ankle fractures in elderly patients. Materials and methods: We report indications, surgical technique, and the clinical outcomes and complication rate in our series to date. A retrospective review was performed at our level 1 major trauma centre. Patient demographics, comorbidities, and 12-month post-operative course were collected. Fractures were classified using the OTA/AO and modified Gustilo–Anderson classification. Fifteen patients underwent the procedure. We present data with a minimum 12-month follow-up. The median age of the patients in this cohort was 83 years (range, 51–102). Five patients were diabetic. Six patients (6/15; 40%) presented with an open fracture. Results: At final follow-up, fourteen patients reported painless walking and had returned to baseline activity. Conclusion: This technique may serve as a salvage procedure, with indications similar to those for tibio-talar-calcaneal arthrodesis. Indications would include non-constructible pilon fractures, comminuted intra-articular fractures in low-demand patients, or patients at high risk of wound complications. Level of clinical evidence: 3 [ABSTRACT FROM AUTHOR]

Background: The Tibialis Posterior tendon (TPT) is the only tendon to encounter the distal tibia and is therefore at greatest risk of injury in fractures of the distal tibia. Although TPT injury has been reported rarely with injuries around the ankle, they often have been missed and present late. Aim: Our aim was to analyse the rate to TPT entrapment in fractures involving the posterior tibia, i.e. Pilon (PLM) and posterior malleolar fractures (PMF). Methods: A retrospective analysis of PMF and Pilon fractures over an 8-year period was undertaken. Patients who had undergone surgical fixation of their PMF or PLM were identified from 2014 to 2022, using our prospectively collected database. Any fracture which had undergone a preoperative CT was included. Analysis of their pre-operative CT imaging was utilised to identify TPT entrapment, where if < 50% of the tendon cross section was present in the fracture site, this was denoted as a minor entrapment and if ≥ 50% of the tendon was present in the fracture site was denoted as major. Results: A total of 363 patients were identified for further analysis, 220 who had a PMF and 143 with PLM injury. The incidence of TPT entrapment was 22% (n = 79) with 64 minor and 15 major entrapments. If the fracture line entered the TPT sheath, there was a 45% rate (72/172) of entrapment as compared to 3.7% (7/190) in fractures not entering the sheath (p <.001). There was no significant difference in TPT entrapment in PMF as compared to PML (p = 0.353). Conclusion: In our assessment, we found significant prevalence of 22% of TPT entrapment in fractures involving the posterior tibia. PMF and PLF had no statistically significant difference in the rate of TPT entrapment. Additionally, we found that there was a significant risk of TPT entrapment when the CT images display the fracture line entering the tendon sheath. We recommend that surgeons consider taking care assessing pre-operative imaging to seek to identify the TPT and to assess intraoperatively where entrapment does occur. [ABSTRACT FROM AUTHOR]

Background: To investigate the clinical effects of a unilateral external fixator combined with bone transport and tibio-talar fusion in the treatment of severe postoperative infection of peri-ankle fractures. Methods: The clinical data of 32 patients (22 men and 10 women) with severe postoperative infection of peri-ankle fractures were retrospectively analyzed. Patients' age ranged from 26 to 62 (mean, 42 ± 9.5) years old. The types of fractures were distal tibia fracture (25 cases), distal tibia and fibula fracture (5 cases), and talus fracture (2 cases). All patients underwent treatment with unilateral external fixation combined with bone transport and tibio-talar fusion. 6 patients with severe infection received two-stage treatment involving focal debridement and external fixation, osteotomy, and bone transport. The remaining 26 patients underwent debridement, external fixation, and osteotomy simultaneously. The length of bone transport, total fixation time of the external fixator, and postoperative complications were recorded for all patients. The efficacy of the treatment was assessed using the American Association of Foot and Ankle Society (AOFAS) ankle–hindfoot score. Results: Patients were followed up for 16–36 months, with an average follow-up time of 24 months. The length of tibia bone transport ranged from 5 to 15 cm, with a mean length of 8.5 cm. The external fixator was applied for 12–24 months, with an average duration of 16 months. One patient suffered from refracture at tibio-talar fusion site, and one patient had external fixation pin-tract infection. No complications, such as recurrent infections (especially the MRSA infection), poor mineralization, refracture, iatrogenic nerve damage or fusion failure, were found in the remaining patients. The preoperative AOFAS ankle–hindfoot function score was 40.0 ± 3.8 (range, 30–52) points, and it increased to 75.0 ± 3.0 (range, 67–78) points at the last follow-up. Conclusion: A unilateral external fixator combined with bone transport and tibio-talar fusion is an effective method for treating severe postoperative infection of peri-ankle fractures. This approach is capable of reconstructing large bone defects that remain after clearing the infected lesion. Additionally, it provides stability to the ankle, enhances ankle–hindfoot function, and improves the patient's quality of life. [ABSTRACT FROM AUTHOR]

Venous thromboembolism (VTE) is a major cause of morbidity and mortality in the trauma setting, and both prediction and prevention of VTE have long been a concern for healthcare providers in orthopedic surgery. The purpose of this study was to evaluate the use of novel statistical analysis and machine-learning in predicting the risk of VTE and the usefulness of prophylaxis following ankle fractures. The medical profiles of 16,421 patients with ankle fractures were screened retrospectively for symptomatic VTE. In total, 238 patients sustaining either surgical or nonsurgical treatment for ankle fracture with subsequently confirmed VTE within 180 days following the injury were placed in the case group. Alternatively, 937 patients who sustained ankle fractures managed similarly but had no documented evidence of VTE were randomly chosen as the control group. Individuals from both the case and control populations were also divided into those who had received VTE prophylaxis and those who had not. Over 110 variables were included. Conventional statistics and machine learning methods were used for data analysis. Patients who had a motor vehicle accident, surgical treatment, increased hospital stay, and were on warfarin were shown to have a higher incidence of VTE, whereas patients who were on statins had a lower incidence of VTE. The highest Area Under the Receiver Operating Characteristic Curves (AUROC) showing the performance of our machine learning approach was 0.88 with 0.94 sensitivity and 0.36 specificity. The most balanced performance was seen in a model that was trained using selected variables with 0.86 AUROC, 0.75 sensitivity, and 0.85 specificity. By using machine learning, this study successfully pinpointed several predictive factors linked to the occurrence or absence of VTE in patients who experienced an ankle fracture. Training these algorithms using larger, more granular, and multicentric data will further increase their validity and reliability and should be considered the standard for the development of such algorithms.

Open ankle fractures in elderly patients are challenging injuries to manage. The aim of this study was to assess the outcome of elderly patients with open ankle fractures treated with a tibiotalocalcaneal nail and primary wound closure. We identified all open ankle fractures in patients over 65 referred to our major trauma centre managed with a tibiotalocalcaneal nail and primary wound closure over 10 years. We recorded patient demographics, comorbidities, injury mechanism, length of stay, operation, weightbearing status, re-operations, infections and mortality. We included 34 patients with an average age of 87 (73−99). We found 56 % of patients' mobility status declined post-operatively and 21 % of patients were discharged directly home. Four patients required further unplanned surgery including two deep infections requiring amputation. We had a 6 % three month mortality rate. Use of a tibiotalocalcaneal nail with primary wound closure offers a reasonable treatment option for open fractures of the ankle in the elderly patient. [ABSTRACT FROM AUTHOR]

Background: The classic operative management of ankle fractures is open reduction- internal fixation (ORIF). Despite radiographic evidence of anatomic reduction, there is a failure to achieve good clinical outcomes. The high incidence of concomitant intra-articular pathology associated with ankle fractures that may go unrecognized using traditional open approaches is possible reason for this. Methods: The main target of this research is to evaluate frequency of cartilage injuries with ankle fracture and its effect on functional outcome. This is a prospective study was carried out in orthopedic department at Zagazig university hospital on 49 patients with ankle fracture managed by fixation with concomitant usage of arthroscopy. Results: In this study 40 patients had cartilage injuries (83%) and 9 cases were free. As regarding syndesmotic injuries, 23 patients (48 %) had syndesmotic injuries which were complete rupture (13 cases) and partial injuries involve rupture of anterior tibiofibular ligament rupture (10 cases). The functional results were graded according AOFAS score as excellent in 16 patients, good in 20 patients, fair in 10 patients, with poor results in 3 patients. Conclusions: The ankle arthroscopy has prognostic and diagnostic advantages that can help to manage ankle fracture. we expect that arthroscopy will be mandatory in dealing with ankle injuries as it is superior to traditional methods in showing hidden side of trauma.

Objective: This review provides guidance and ideas for researchers through a comprehensive and comparative analysis of the present state, trends, and hotspots in the pediatric fracture literature over the past 6 years. Methods: We used Citespace 6.1.R6 software to explore the country/region distribution, institutions, journals, keyword analysis, and co-cited references of the literature from Web of Science core database. Results: There are 6472 pieces of pediatric fracture–related literature, including 2962 from 2017 to 2019 and 3510 from 2020 to 2022. The country with the most papers is the United States, and US institutions and journals also have a pivotal position in this field. Research hotspots for pediatric fractures in 2017–2019: The topic with the most attention is bone mineral density leading to related bone diseases. Treatment for pediatric fractures, including supracondylar humeral fractures, Monteggia fractures, forearm fractures, knee fractures, and ankle fractures in children, is another topic of greater interest. Brain injuries and dental injuries in children due to abuse and trauma are also concerning issues. Research hotspots for pediatric fractures in 2020–2022: comparison with 2017–2019 revealed a relative decrease regarding ankle-related epiphyseal injuries, but there is a higher focus on the epidemiology of fractures in children, risk factors, and reasons for childhood trauma. We have confirmed through literature co-citations that the literature of high interest is also in these aspects. Conclusion: Researchers and clinicians can quickly learn about topics of interest through authoritative journals and highly cited literature and rapidly master the current status and frontiers of the field through study, providing ideas for future work.

Ankle fractures are a common injury in both sporting professionals and amateurs, with football and rugby contributing most to these injuries in the UK population. Mechanism of injury varies but commonly involves excess rotational forces around a fixed plantigrade foot. Classification of ankle fractures is discussed along with a description of the anatomy involved. Management of these injuries can be operative or non-operative and is judged based on the stability and displacement of the ankle mortise. Debate persists around optimal methods of fixation, particularly with regards to syndesmotic injury and deltoid ligament repair and the various options are outlined. A return to sport is possible and, in fact, expected in most of these fractures sustained in a sportsperson and, hence, a focus on early mobility and weight-bearing is encouraged in this population. Here we discuss these considerations in the context of athletes. [ABSTRACT FROM AUTHOR]

Purpose: The systematic review aims to establish the value of using 3D printing-assisted pre-operative planning, compared to conventional planning, for the operative management of foot and ankle fractures. Methods: The systematic review was performed according to PRISMA guidelines. Two authors performed searches on three electronic databases. Studies were included if they conformed to pre-established eligibility criteria. Primary outcome measures included intraoperative blood loss, operation duration, and fluoroscopy time. The American orthopaedic foot and ankle score (AOFAS) was used as a secondary outcome. Quality assessment was completed using the Cochrane RoB2 form and a meta-analysis was performed to assess heterogeneity. Results: Five studies met the inclusion and exclusion criteria and were eventually included in the review. A meta-analysis established that using 3D printed models for pre-operative planning resulted in a significant reduction in operation duration (mean difference [MD] = − 23.52 min, 95% CI [− 39.31, − 7.74], p = 0.003), intraoperative blood loss (MD = − 30.59 mL, 95% CI [− 46.31, − 14.87], p = 0.0001), and number of times fluoroscopy was used (MD = − 3.20 times, 95% CI [− 4.69, − 1.72], p < 0.0001). Using 3D printed models also significantly increased AOFAS score results (MD = 2.24, 95% CI [0.69, 3.78], p = 0.005), demonstrating improved ankle health. Conclusion: The systematic review provides promising evidence that 3D printing-assisted surgery significantly improves treatment for foot and ankle fractures in terms of operation duration, intraoperative blood loss, number of times fluoroscopy was used intraoperatively, and improved overall ankle health as measured by the AOFAS score.

The study aims to evaluate the clinical application of posterior tibial artery or peroneal artery perforator flap in the treatment of plate exposure after ankle fracture fixation. A posterior tibial artery or peroneal artery perforator flap was used on 16 patients with plate exposure after ankle fracture fixation in our hospital between July 2018 and July 2021. The time required to harvest the flap, the amount of intraoperative blood loss, the duration of postoperative drainage tube placement, the outcome of the flap and the healing observed at the donor site are reported. The sizes of the flaps were 2.5–7.0 cm × 5.0–18.0 cm and averaged 4.0 cm × 12.0 cm. The time required to harvest the posterior tibial artery or peroneal artery perforator flap ranged from 35 to 55 min and averaged 45 min. The amount of intraoperative blood loss ranged from 20 to 50 mL and averaged 35 mL. The duration of postoperative drainage tube placement ranged from 3 to 5 days and averaged 4 days. A total of 15 flaps survived and one flap had partial necrosis and survived after conservative treatment. All donor area defects were directly sewed and stitched without complications. There are multiple advantages of the posterior tibial artery or peroneal artery perforator flap, including simple preparation technique, reliable repair of the defects and without the need for performing microvascular anastomosis. It can be safely used in curing plate exposure after ankle fracture fixation and worth popularizing in grassroots hospitals. [ABSTRACT FROM AUTHOR]
