Distal humerus fractures are common, and when they occur in elderly patients with osteoporotic bone or poor subchondral bone stock, intra-articular fragmentation is common and management can be challenging. Osteosynthesis may be impossible or associated with a high risk of complications in this subset of patients, and total elbow replacement may be the preferred treatment. Elbow hemiarthroplasty for unreconstructable distal humerus fractures has emerged as an alternative treatment option and now accounts for over 50% of arthroplasty procedures for distal humerus fractures in England. This article aims to look at the indications, contraindications, surgical anatomy and technique as well as the outcomes and complications of elbow hemiarthroplasties. [ABSTRACT FROM AUTHOR]

Background: The pins and rubber traction system (PRTS) has proven effective in managing intra-articular fractures of the proximal interphalangeal joint. However, there is scant evidence in the literature regarding its efficacy in treating distal interphalangeal joint (DIPJ). This study aims to investigate the outcomes of PRTS in the treatment of comminuted intra-articular fractures of the DIPJ. Methods: We conducted a retrospective review of patients with comminuted intra-articular fractures of the DIPJ treated with PRTS between 2017 and 2021. At the final follow-up, we measured and compared the active range of motion (ROM) in both affected and non-injured contralateral fingers. The subjective evaluation utilised the Quick Disabilities of the Arm, Shoulder and Hand (Quick-DASH) questionnaire and the Visual Analogue Scale (VAS). Results: Ten patients with a mean follow-up of 13.2 months (range: 12–17) were included in the study. Fracture locations included the base of the distal phalanx in two patients, the condyle of the middle phalanx in seven and both in one patient. At the final follow-up, the average VAS score was 0.5 (range: 0–2). The average active motion of the DIPJ was 61° (range: 50°–70°) for the injured side and 76° (range: 75°–80°) for the opposite side. The mean range of DIPJ movement was 80% (range: 68%–87%) of the non-injured side. Extension deficits were observed in five patients, with a median deficit value of 10° (range: 5°–10°). The average Quick-DASH score was 2.9 (range: 0–11.3). Conclusions: The PRTS can be considered as an effective surgical technique in managing comminuted intra-articular fractures of the DIPJ. Level of Evidence: Level IV (Therapeutic) [ABSTRACT FROM AUTHOR]

Glenoid fossa fractures are rare injuries accounting for 10 to 29% of all intra-articular scapula fractures. They are usually the result of high-energy trauma, and concomitant injuries are not uncommon. Patients with glenoid fractures are admitted with shoulder pain and restricted range of motion. Although shoulder plain radiographs could establish the diagnosis, a computed tomography scan is necessary to adequately define the fracture pattern and characteristics. The most commonly used classification system is that of Ideberg (modified by Goss), which includes five glenoid fossa fracture types according to the location, extension, and complexity of the lesion. Articular surface displacement and step-off are the most important factors that should be taken under consideration when deciding for conservative or surgical management. Operative treatment includes open reduction and internal fixation through a posterior or anterior approach depending on fracture morphology and displacement. However, open surgical techniques are related to extensive soft-tissue disruption, risk of neurovascular injury, and inadequate exposure of the entire glenoid cavity. Introduction of arthroscopy could facilitate better visualization of the glenoid articular surface and improved fracture reduction. However, it is a technically demanding procedure with many challenges and pitfalls. The aim of this review is to summarize the current evidence regarding the treatment of glenoid fossa fractures and present the beneficial effect of arthroscopy in improving the quality of fracture fixation and overall functional outcomes.

Distal radius fractures are a prevalent orthopedic challenge, often necessitating surgical intervention for optimal outcomes. This study focuses on the of Open Reduction Internal Fixation (ORIF) in the management of these fractures, exploring the nuanced interplay between patient demographics, fracture characteristics, and postoperative recovery. Through a retrospective analysis of cases, we aim to provide insights into the efficacy of ORIF, elucidating the factors influencing surgical decision-making and the impact on functional outcomes. The study contributes valuable information to the orthopedic community, aiding in the refinement of treatment protocols for distal radius fractures. [ABSTRACT FROM AUTHOR]

Background: We treated distal radius fractures (DRFs) beyond the watershed line without fracture of the lunate volar rim using a volar locking plate (VLP) and report the radiological and clinical outcomes at least 3 years after surgery. Methods: In 41 consecutive patients between January 2012 and August 2017, the fragment was composed of the radial styloid process (distal to the watershed line) and the lunate volar rim was intact. We evaluated demographic factors, radiological features and radiological/clinical outcomes at the final follow-up. Results: Twenty-nine patients were followed and evaluated. The mean follow-up period was 5.7 years. The mean patient age was 52.7 years and 24 patients had intracapsular intra-articular fractures. The fracture line was present in the lunate fossa in all patients. Twenty patients were classified as Soong grade 2, and five and four patients were grades 1 and 0, respectively. No radiological parameter (volar tilt, radial inclination, step-off and ulnar variance) was significantly different between the affected and contralateral normal sides. The mean visual analogue scale pain score and Disabilities of the Arm, Shoulder and Hand score, as well as the range of movement of the wrist, were not different between the affected and contralateral normal wrists. Finally, the grip strength on the affected side was 92% of the contralateral value. Major complications, such as nonunion, malunion and tendon rupture, were absent. Conclusions: DRFs distal to the watershed line with an intact lunate volar rim are rare and easy to miss. Careful inspection of 3D-CT images is necessary to determine these injuries, and the optimal choice for proper fixation of the fragment amongst the commercial VLPs would result in satisfactory radiological and clinical outcomes. Level of Evidence: Level IV (Therapeutic) [ABSTRACT FROM AUTHOR]

Background: Fractures of the distal femur are seen in different complexities in modern times. The management of comminuted distal femur fracture is challenging given achieving stable fixation, and regaining of range of motion at the knee joint treated with present fixation methods. Distal femur plating on the lateral aspect is a good option but in long-term follow up various complications are seen like shorting of limb, angulations, deformity at the knee due to banding of plats, poor healing of the fracture, delayed union and stiffness of knee due to immobilizations. To overcome all these complications of double plate fixation i.e. conventional lateral pillar (LCP) fixation, augmented with medial per admission and availability of the operation theatre. Most of the cases can be operated between the 2nd to 10th day admission. After preoperative assessment cases were prepared for surgery. Under aseptic precaution and prophylactic antibiotic coverage, cases are operated on. All will be operated by dual-femur LCP. Results: Out of all 30 patients 07(23.33%) was Excellent, 20(66.66%) was good, 02(6.66%) was fair, 01(3.33%) was poor results. Of the 30 cases, 4 (13.33%) patients have a Range Of Motion of 80-100o, 26 (86.66%) patients have a Range Of Motion of 101-120o Conclusion: All the end of this prospective study we found this method suitable for complex distal femur fractures AO Type C. The addition of a medial buttress plate resulted in better outcomes in comparison to single lateral buttress plates. Double platting was successful in achieving bony union without complications, like loss of reduction, implant failure, or breakage. Late angulation deformity or non-union was not seen in any case. Rigid fixation allowed early mobilization of the knee and enhance rehabilitation. We conclude our study that double platting of AO Type C 1,2,&3 subtypes gave encouraging results in terms of functional outcomes in comparison to a lateral plate. We conducted an original study in all subtypes of AO types C. In last we recommend that further study on Type C specific sub-types will produce better results. [ABSTRACT FROM AUTHOR]

Introduction: Proximal tibial plateau fractures are one of the major problems in orthopaedic surgery and are associated with high complication rates. Intra-articular proximal tibia plateau fractures represent approximately 1% of fractures in adults. Various modalities of proximal tibial plateau fracture management have been considered, ranging from simple external fixators in impending compartment syndrome to periarticular proximal tibia plates and inter-locking nails with poller screws. Purpose of this study is to determine clinical outcomes of proximal tibial plateau fractures treated with plate. Materials and methods: We did this study of proximal tibial plateau fracture according to Schatzker’s classification treated with proximal tibial periarticular plates in 53 patients prospectively admitted at the author’s institute from June 2018 to May 2020 with follow-up period of 6 months. Results: In our study, the average knee score was 89.30 (ranging from 79 to 93) and functional knee score was 97.92 (ranging from 75 to 100). Fifty-one (51) patients (96.23%) showed excellent results and 2 patients (3.77%) showed good results according to Knee Society Score, which suggest that internal fixation of proximal tibia plateau fracture with plating provides better results. Out of 53 patients, 9 patients had post-operative complications. Average radiological union was seen at 14 weeks. Conclusion: Locking compression plate in proximal tibia plateau fractures act as a good biological fixation provide stable fixation, articular reduction and limb alignment even in difficult fracture situations. Fixation of proximal tibia plateau fractures with plate gives excellent to good knee society score, with satisfactory functional and radiological outcome.

Volar locking plate fixation for distal radius fractures (DRFs) is a technically demanding procedure with a risk of distal screw penetration through the dorsal cortex or the articular surface. This study aimed to investigate the incidence and details of distal screw penetration after volar locking plate fixation for intra-articular DRFs using a CT scan and to evaluate the relationship between the incidence of screw penetration and fracture comminution severity and the clinical complications of screw penetration. This was a retrospective case series of 91 adult patients (mean age, 63 years; 27 men) who underwent volar locking plate fixation for intra-articular DRFs from 2015 to 2018. The positioning of the distal screws was evaluated using a postoperative CT scan, and radiological outcomes were compared between the AO C1 and C3 groups. At the final follow-up, tendon rupture and arthritis severity were assessed as clinical complications of dorsal and intra-articular screw penetration. Distal screw penetration was observed in 44 wrists (48%), dorsal cortex screw penetration in 34, intra-articular screw penetration in 13, and both dorsal cortex and intra-articular screw penetration in three. The incidence of intra-articular screw penetration was significantly higher in the C3 group than in the C1 group. No tendon rupture was observed. Multivariable analysis revealed that intra-articular screw penetration was significantly related to high severity of arthritis. Approximately half of the study patients with intra-articular DRFs had distal screw penetration. The incidence of intra-articular screw penetration was associated with the severity of fracture comminution, and the intra-articular screw penetration was associated with the incidence of early radiocarpal arthritis. Intra-articularly penetrating screws should be replaced as soon as they are discovered, regardless of the length of penetrated screw or absence of patients' subjective symptoms. Therapeutic IV.

Background: Unlike articular shear fractures of the distal radius, radiocarpal fracture‐dislocations defined as complete dislocation of the lunate from its articular facet of the radius are relatively uncommon. The management principles of these fractures have not been defined and there is no consensus on approach to management of these injuries. The aim of this study is to review our series of radiocarpal fracture‐dislocations and propose a radiographic classification to guide surgical management. Methods: This study is reported based on STROBE guidelines. A total of 12 patients underwent open reduction and internal fixation. All the fracture‐dislocations were dorsal and satisfactory objective outcomes achieved were comparable to literature. Injury morphology‐specific management approach was used based on the size of dorsal lip fragment and the volar teardrop fragment attached to the short radiolunate ligament assessed by preoperative CT scans. Results: All patients with known outcome (n = 10) went on to resume their prior occupation and hobbies that included high‐demand activities and manual labour at mean follow‐up of 27 weeks. Average wrist flexion was 43° and wrist extension was 41° while radial and ulnar deviation were 14° and 18° respectively. Average forearm pronation was 76° and supination was 64° at final follow‐up. Conclusion: We describe four injury patterns of radiocarpal fracture‐dislocations based on preoperative CT scans that guide fixation. We believe that early recognition of radiocarpal fracture‐dislocations and appropriate management can yield satisfactory outcomes. [ABSTRACT FROM AUTHOR]

Abstract Objective To compare the clinical efficacy of minimally invasive percutaneous treatment by ligamentotaxis with traditional open reduction and internal fixation in the treatment of Essex-Lopresti joint depression-type displaced intra-articular calcaneal fractures (DIACFs). Methods The medical records of patients with calcaneal fractures admitted to our department from January 2016 to December 2020 were retrospectively analyzed, and patients who met the inclusion criteria were finally included for analysis. Twenty-one patients underwent minimally invasive percutaneous treatment by ligamentotaxis (Group A), while eighteen patients were treated by traditional open reduction and internal fixation through an extended lateral approach (Group B). The preoperative waiting time, operative time, hospital stay, radiologic parameters (calcaneal height, width, length, Böhler angle and Gissane angle), American Foot and Ankle Surgery Association (AOFAS) hindfoot scores, Maryland Foot Score (MFS), visual analogue scale (VAS), and incidence of complications of the included patients were all recorded and analysed. Results Thirty-nine patients with Essex-Lopresti joint depression type DIACFs were finally included. According to the Sanders classification, 22 were type II, 12 were type III and 5 were type IV. The preoperative waiting time and the hospital stay of Group A were 3.7 ± 1.6 d and 7.2 ± 1.7 d, respectively, which were significantly shorter than those of Group B (6.9 ± 2.0 d and 12.4 ± 1.5 d) (P 0.05). No significant differences were shown in the radiological parameters (calcaneal height, width, length, Böhler angle and Gissane angle) or the satisfactory rate of joint surface reduction (SRJSR) of the two groups immediately postoperatively. All patients were followed up for 14 to 56 months [(30.2 ± 10.4) months]. All fractures healed. At the final follow-up, there were no significant differences in the radiological parameters or the SRJSR between the two groups (P > 0.05). No significant differences were shown in the AOFAS scores, MFS or VAS scores between the two groups [(89.5 ± 8.2) vs. (89.4 ± 9.0), P > 0.05; (87.5 ± 8.3) vs. (86.3 ± 8.9), P > 0.05; and (2.1 ± 1.2) vs. (2.2 ± 1.2), P > 0.05]. The excellent and good rates of the AOFAS scores and MFS were 90.5% and 85.7%, respectively, in Group A and 88.9% and 88.9%, respectively, in Group B (P > 0.05). Four patients experienced wound complications, including 1 superficial incision infection, 2 skin necrosis around the incision edge and 1 deep infection in Group B, while there were no wound complications in Group A (P 0.05). Conclusions In the assessment of Essex-Lopresti joint depression type DIACFs, minimally invasive percutaneous treatment by ligamentotaxis has similar clinical outcomes to traditional open reduction and internal fixation through an extended lateral approach. However, the former has the advantages of shorter preoperative waiting time and hospital stay, and lower incidence of incision complications.

Abstract Background When a fracture goes into or around a joint, it usually damages the cartilage at the ends of bones and other joint tissue. As a result, the affected joints are prone to traumatic arthritis, leading to stiffness. Repairing bone damage, maintaining joint integrity, and avoiding subchondral and metaphyseal defects caused by comminuted fractures is often a great challenge for orthopedic surgeons. Tissue engineering of synthetic bone substitutes has proven beneficial to the attachment and proliferation of bone cells, promoting the formation of mature tissues with sufficient mechanical strength and has become a promising alternative to autograft methods. The purpose of this study is to retrospectively evaluate the clinical outcome and efficacy of a novel synthetic, highly biocompatible, and fully resorbable Ca/P/S-based bone substitute based on medical image findings. Materials and methods A synthetic, inorganic and highly porous Ca/P/S-based bone-substituting material (Ezechbone® Granule, CBS-400) has been developed by National Cheng-Kung University. We collected fourteen cases of complex intra- and peri-articular fractures with Ezechbone® Granule bone grafting between 2019/11 and 2021/11. We studied the evidence of bone healing by reviewing, interpreting and analyzing the medical image recordings. Results In the present study, CBS-400 was observed to quickly integrate into surrounding bone within three weeks after grafting during the initial callus formation of the early stage of repair. All of these cases healed entirely within three months. In addition, the patient may return to daily life function after 3.5 months of follow-up and rehabilitation treatment. Conclusions Ezechbone® Granule CBS-400 was proved capable of promoting bone healing and early rehabilitation to prevent soft tissue adhesions and joint contractures. Moreover, it has a high potential for avoiding ectopic bone formation or abnormal synostosis. Trial registration The Institutional Review Board at National Cheng Kung University Hospital (NCKUH) approved the study protocol (A-ER-109-031, 3-13-2020).

Articular fracture malreduction increases posttraumatic osteoarthritis (PTOA) risk by elevating joint contact stress. A new biomechanical guidance system (BGS) that provides intraoperative assessment of articular fracture reduction and joint contact stress based solely on a preoperative computed tomography (CT) and intraoperative fluoroscopy may facilitate better fracture reduction. The objective of this proof‐of‐concept cadaveric study was to test this premise while characterizing BGS performance. Articular tibia plafond fractures were created in five cadaveric ankles. CT scans were obtained to provide digital models. Indirect reduction was performed in a simulated operating room once with and once without BGS guidance. CT scans after fixation provided models of the reduced ankles for assessing reduction accuracy, joint contact stresses, and BGS accuracy. BGS was utilized 4.8 ± 1.3 (mean ± SD) times per procedure, increasing operative time by 10 min (39%), and the number of fluoroscopy images by 31 (17%). Errors in BGS reduction assessment compared to CT‐derived models were 0.45 ± 0.57 mm in translation and 2.0 ± 2.5° in rotation. For the four ankles that were successfully reduced and fixed, associated absolute errors in computed mean and maximum contact stress were 0.40 ± 0.40 and 0.96 ± 1.12 MPa, respectively. BGS reduced mean and maximum contact stress by 1.1 and 2.6 MPa, respectively. BGS thus improved the accuracy of articular fracture reduction and significantly reduced contact stress. Statement of Clinical Significance: Malreduction of articular fractures is known to lead to PTOA. The BGS described in this work has potential to improve quality of articular fracture reduction and clinical outcomes for patients with a tibia plafond fracture. [ABSTRACT FROM AUTHOR]

Post-traumatic osteoarthritis (PTOA) develops secondary to a joint injury and accounts for 12 % of all osteoarthritis. These injuries, often of the lower extremity joints, occur due to trauma or accidents related to athletic or military activities. They primarily affect younger individuals although PTOA can occur across the spectrum of age. Pain and functional disability caused by PTOA confer a heavy economic toll on patients, in addition to detrimentally affecting their quality of life. Both high energy injuries that cause articular surface fracture with or without subchondral bone disruption and low-energy injuries involving joint dislocations or ligamentous injury cause PTOA, albeit through different mechanisms. Regardless, chondrocyte death, mitochondrial dysfunction, reactive oxygen species production, subchondral bone remodeling, inflammation and cytokine release in the cartilage and synovium play integral roles in the pathogenesis of PTOA. Evolving surgical methods are focused on stabilizing articular surface and joint structure congruity. However, to date there are no disease modifying medical therapies against PTOA. Increased recent understanding of the pathogenesis of the subchondral bone and synovial inflammation as well as that of chondrocyte mitochondrial dysfunction and apoptosis have led to the investigation of new therapeutics targeting these mechanisms to prevent or delay PTOA. This review discusses new advances in our understanding of cellular mechanisms underlying PTOA, and therapeutic approaches that are potentially effective in reducing the self-propagating cycle of subchondral bone alterations, inflammation, and cartilage degradation. Within this context, we focus therapeutic options involving anti-inflammatory and anti-apoptotic candidates that could prevent PTOA.

Though research exists regarding calcaneal fractures, the treatment approach for displaced intra-articular calcaneal fractures (DIACF) remains controversial. The most common approach, the extensile lateral approach (ELA), for the treatment of DIACFs has high rates of wound complications reported. In contrast, the sinus tarsi approach (STA) is becoming more popular due to its minimally invasive technique. The objective of this retrospective study is to investigate the incidence of wound complications in high-risk patients with DIACF following operative fixation via the STA. Following IRB approval, a retrospective chart review was performed between 2007 and 2013 to assess high-risk patients for the presence of wound complications, including deep infections and delayed wound healing, following the use of STA for the management of DIACF's (n = 36). Demographics, risk factors, and secondary outcomes such as time to surgery were recorded. Of the 36 high-risk patients included in our study, seven had post-operative complications following operative fixation via the STA. Specifically, four patients had delayed wound healing, and three developed deep infections. Time to surgery had the greatest negative effect on postoperative complications and was influenced by age, sex, and the presence of a concomitant injury. In conclusion, this study demonstrates that the STA is a viable option for high-risk patients with displaced intra-articular fractures. Additionally, time to surgery should be minimized, when possible, to reduce risks of post-operative complications, including infections and delayed wound healing. [ABSTRACT FROM AUTHOR]

Malunion of an intra-articular fracture of the metacarpophalangeal joint can cause a dramatic effect, decreasing mobility and strength. For small joints, surgical options are often drastic; joint arthroplasty or arthrodesis. However, in cases of preserved joint space, an intra-articular osteotomy can be proposed. In order to improve preoperative planning, considering the small size of the articular surface and the importance of a precise osteotomy plane, we used a preoperative three-dimensional printed template to perform the intra-articular opening wedge osteotomy. This was followed by plate and screw osteosynthesis after adding a freeze-dried allograft to the created defect. The outcome at 1-year follow-up was more than satisfactory, with a normal range of motion and a restored, painless grip strength. A three-dimensional printed template is a useful, accurate, and efficient method to correct malunion of intra-articular fractures of the base of the proximal phalanx at the metacarpophalangeal joint.

Background: Intra-articular fibromembranous septum in the radiocarpal joint can cause wrist contracture after distal radial fracture, but the mechanism underlying the formation of the septum is unknown. This study examined the clinical outcomes in patients treated with arthroscopic excision of the septum and the factors associated with formation of the septum in patients with and without a septum.Methods: Fifty-three patients (22 with septum and 31 without septum) treated for intra-articular distal radial fracture with arthroscopy using a volar locking plate and secondary removal of the plate were included. Clinical outcomes and radiological assessments were analyzed.Results: In patients with a septum, the range of wrist flexion and total wrist arc before the second operation were significantly more limited than in those without a septum (p < 0.01 and p = 0.03, respectively). The improvement rate (improvement in wrist arc divided by the wrist arc of the healthy side) after arthroscopic excision of the septum and plate removal was greater in patients with a septum than in those without a septum (6.1% vs. 2.0%, p = 0.08). The significant factors affecting formation of the septum were the residual articular gap and the height of the midradial ridge on computed tomography images.Conclusions: Intra-articular fibromembranous septum after surgically treated intra-articular distal radial fracture affects limited range of motion and secondary arthroscopic excision of the septum improves the wrist range of motion. Anatomical reduction and maintenance of the articular fragment, as well as anatomical characteristics might be causes of septum formation. [ABSTRACT FROM AUTHOR]

Introduction: The percutaneous pinning method described by Iselin is one of the techniques used for treating Bennett fractures at the base of the thumb metacarpal. There is little published data on the medium- and long-term outcomes of this treatment, with most studies having a mean follow-up of 4 years. The primary objective of this study was to evaluate the functional and radiological outcomes of percutaneous pinning by Iselin's method with a mean follow-up of 6 years. The secondary objective was to look for evidence of radiographic carpometacarpal (CMC) arthritis., Hypotheses: 1) The functional outcomes are good, and the clinical outcomes are comparable to the contralateral side. 2) While radiographic CMC arthritis may be present in the medium term, it will not interfere with work and recreational activities., Methods: This was a single-center, multiple-surgeon, retrospective case series. Twenty-nine patients were included who had a mean and median follow-up of 6 years (min 2, max 14). The functional outcomes (satisfaction, pain, subjective strength deficit, DASH), clinical outcomes (tip pinch, key pinch and grip strength compared to contralateral side) and the thumb's mobility (abduction angle, Kapandji score) were determined. Return to work and recreational activities were documented. CMC arthritis was assessed on lateral radiographs of the thumb in neutral position based on the Eaton-Littler classification., Results: The average patient satisfaction score was 87% (20; 100). The mean pain level was 0.7/10 (0-8) at rest and 2/10 (0-10) during effort. The subjective strength deficit was 12% ± 16. The mean DASH score was 8.8/100 (0-43). The mean tip-pinch strength in the operated thumb was significantly lower than the contralateral side (-9.3% ± 16.5), as was the mean key-pinch (-6.3% ± 16.9). Thumb abduction was significantly reduced relative to the contralateral side (-4.1° ± 5.24) as was the Kapandji score (-0.5 ± 0.81). CMC arthritis was visible on 100% of radiographs (96% were stage 1 or 2)., Discussion: The surgical treatment of Bennett fractures by percutaneous pinning using the Iselin method produces satisfactory functional outcomes in the medium term, although there was a moderate loss of strength and mobility in the thumb., Level of Evidence: IV; retrospective, single-center case series., Competing Interests: Declaration of competing interest TD, PJL, CC: these authors declare that they have no competing interest.

Distal humeral intra-articular fractures often result in functional impairment if treated conservatively. These fractures are particularly challenging due to osteoporosis and severe comminution. A 32-year-old female with a grade three open distal humerus intra-articular fracture presented with a 5 cm x 5 cm open wound on her right elbow. The patient underwent open reduction and internal fixation (ORIF) using the BB Joshi external fixator and a local flap for skin coverage, achieving stable fixation and early mobilization. The patient regained a near-normal range of movements and adequate skin coverage of the wound at follow-up. Compared to traditional ORIF, it showed lower infection rates and comparable union rates, leading to better functional outcomes when compared with the studies reported earlier. The BB Joshi external fixator effectively treats grade three open distal humerus intra-articular fractures, minimizing complications and promoting functional recovery., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Treating posterior malleolar fractures of the ankle remains a challenge. The arthroscopic handlebar technique is our novel surgical method used for reduction and fixation of posterior malleolar fractures and involves the restoration of posterior malleolar fractures under anterior arthroscopic guidance and the use of Kirschner wires that penetrates the fractured posterior malleolus. Arthroscopy enables visualization of the intra-articular fracture of the posterior malleolus, and a handlebar reduction bar is used to control the fractured posterior malleolus. The arthroscopic handlebar technique is a promising procedure for reduction and internal fixation of the posterior malleolar fractures. [ABSTRACT FROM AUTHOR]

Introduction: Securing stable internal fixation for fractures in osteoporotic intra-articular distal femur proves to be a demanding task due to thin cortices, a wide medullary canal, diminished bone stock, and fracture comminution. No singular therapeutic approach has successfully tackled all facets of this injury. Consequently, we now introduce a pioneering fixation method in our report, aiming to offer a holistic solution to the intricate challenges associated with this scenario., Case Report: A 60-year-old female presented with an intra-articular distal femur fracture, and underwent a combination fixation of distal femur plate and intramedullary interlocking nailing. The patient was rehabilitated with active knee range of motion on post-operative day 7 and has now attained full knee range of motion., Conclusion: The utilization of anatomical plates with locking mechanisms, in tandem with intramedullary interlocking nailing, holds promise for the secure stabilization and fixation of osteoporotic distal femur fractures, potentially leading to an expedited recovery process., Competing Interests: Conflict of Interest: Nil, (Copyright: © Indian Orthopaedic Research Group.)

Proximal phalanx fractures of the big toe involving angulation or dislocation of the articular surface require repositioning and fixation. We treated a patient with such a fracture using a novel wire-connected external fixator, the ICHI-FIXATOR® system. A 45-year-old male sustained an injury when slipping down the stairs and impacting his left big toe. Plain radiography and computed tomography revealed a proximal phalangeal fracture of the left big toe with dislocation of the articular surface and comminution. The surgical intervention was performed using 1.1-mm diameter C-wires and an external fixator. The patient regained ambulation and resumed work immediately after surgery. Four weeks postoperatively, all wires were removed on an outpatient basis. Eight months postoperatively, the patient experienced no pain during strenuous activities or exercises. This novel wire-connected external fixator provides reliable and secure fixation, facilitating a prompt return to normal daily activities. This technique may be an effective option for managing toe fractures., Competing Interests: There are no conflicts of interest to declare., (© 2024 The Authors.)

Fractures of the distal radius show a wide spectrum of different fracture patterns. Although standard X‑ray images are sufficient for extra-articular fractures, the exact analysis of intra-articular fractures requires the use of computed tomography (CT) with coronal, sagittal and axial sectional images. The classification is based on the Working Group for Osteosynthesis Questions (AO) criteria. The treatment strategy can be more precisely defined by a CT-based classification. Special attention must be paid to the presence of the key corners, as they have a high risk for primary or secondary dislocation if they not adequately stabilized., (© 2024.

• ORIF with double pre-contoured locking plates can be a safe and reliable treatment option for type C3 DHF in patients aged 75 years and older. • Good clinical outcomes can be achieved with preservation of motion through anatomic reduction, rigid internal fixation, and early mobilization. • Complications are expected but not related to loss of reduction, fixation failure or revision to elbow arthroplasty. • Patients aged 75 years and older with a type C3 DHF are expected to survive more than 5 years, increasing the risk of complications from TEA. The incidence of osteoporotic distal humeral fractures (DHF) is on the rise. Their operative management is demanding. Fixation with non-locking reconstruction plates was associate with a high number of complications. Elbow arthroplasty (total or hemi) has been proposed as an alternative treatment, in spite of lifetime activity restrictions, and risk of complications, unknown implant survival and problematic revision surgery. Precontoured anatomical locking plates have increased the strength of the fixation in complex fractures. Hypothesis: double plating ORIF with precontoured anatomical locking plates is a safe and reliable treatment option for the management of AO/OTA type C3 DHF in patients aged 75 and older. A retrospective case series study of patients aged 75 years old and older with an AO/OTA type C3 DHF treated with ORIF with double precontoured anatomical locking plates between 2007 and 2021. Pathologic fractures were excluded. Patients' demographic, surgical, clinical, and radiological data were reviewed. A total of 27 women and 3 men, mean age of 80.1 years (range 75–93 years), were included. Mean Charlson index was 5 (range 3–8). Out of 30 patients, 19 had already died. Mean survival time after the surgical treatment was 72.3 months. Mean Mayo elbow performance score was 88.9 (range 60–100); 23 patients scored excellent or good. All fractures healed with no cases of delay union or non-union, hardware failure or loss of reduction. No patient needed a revision surgery to arthroplasty. The total number of complications was 12 (40%), mainly ulnar neuropathy (5) and cerclage removal (4). ORIF with double pre-contoured locking plates may be a safe and reliable treatment for type C3 DHF in patients aged 75 years and older, with a good functional outcome. Complications are expected but not related to loss of reduction, fixation failure or revision to elbow arthroplasty. [ABSTRACT FROM AUTHOR]

Background Distal radius fractures are common fractures. Treatment of intra-articular fractures is controversial, with treatment modalities including closed reduction and casting, open reduction and plating, and closed reduction and fixation with an external fixator. In this study, we compared the clinical and radiological outcomes of our patients treated with three different methods for intra-articular distal radius fractures. We hypothesize that open reduction and plate application are superior. Methodology Adult patients with intra-articular (AO type B and C) fractures of the distal radius and treated with closed reduction-casting, volar locking plate, and external fixator were identified. Radiologically, joint stepping at the end of treatment, radial inclination, radial height, volar tilt, and distal ulna fracture were examined. For clinical scoring, Quick Disabilities of the Arm, Shoulder and Hand (Q-DASH) scores were computed. Obtained data were compared statistically between groups. Results A total of 164 patients were included in the study. Overall, the treatment modality was conservative in 61, volar with plating in 78, and external fixation in 25. The mean age of the patients was 53.7 years (range = 20-82 years). Overall, 39.6% of the patients were male and 60.4% were female. The mean follow-up period of the patients was 16.7 months (range = 12-28 months). No statistically significant difference was found between Q-DASH scores in the statistical evaluation (p > 0.05). There was a statistically significant difference between the groups in the radiological evaluation. When conservative treatment and the volar plate group were compared, the volar plate was superior in all radiological parameters (p < 0.05). Compared with conservative treatment and external fixation, only volar tilt and radial inclination angle were different. External fixation was better (p < 0.05). Radial length, volar compared to plate and external fixation tilt, and ulnar variance were better in the plate group (p < 0.05). Regarding joint stepping and radial, there was no difference in inclination between the two groups (p > 0.05). Reflex sympathetic dystrophy was seen in a total of 10 (6.1%) patients. Pin-site infection was seen in three (12%) patients in the external fixator group. Implant removal was performed in seven (9.0%) patients who developed plaque due to irritation and tenosynovitis. Early arthrosis was seen in three (4.3%) patients. Conclusions The treatment of distal radius intra-articular fractures should be evaluated and decided individually for each patient. No single method is directly superior to other methods. However, in some cases, the best results radiologically in the treatment of comminuted intra-articular fractures have been obtained in patients with volar plates., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Akdemir et al.)

Objective: Surgical treatment of intra-articular calcaneus fractures via a minimally invasive approach., Indications: Intra-articular dislocated calcaneus fractures., Contraindications: Fracture older than 14 days; poor soft tissue quality in the surgical area., Surgical Technique: Patient in lateral position. Identifying the anatomic landmarks. Incision (3-5 cm) from the tip of the fibula to metatarsal IV. Preparation through the subcutis. Retraction of the peroneal tendons. Preparation of the lateral calcaneal wall and later plate position via raspatory. Placement of a Schanz screw in the calcaneal tuberosity from lateral or posterior as a reduction aid for restoring of the calcaneal length and reduction of the hindfoot varus. Reduction of the sustentaculum fragment with the help of fluoroscopy from lateral. Elevation of the subtalar articular surface. Positioning of the calcaneal plate and fixation of the sustentaculum fragment by placing a cannulated screw through the long hole. Afterwards, definite internal fixation of the reduction with locking screws. Completion of the operation with final X‑rays and, if available, an intraoperative computed tomography. Wound closure with closing of the peroneal sheath., Postoperative Management: Lower leg-foot orthoses. Mobilization with partial weight-bearing of the injured foot with 15 kg for 6-8 weeks; subsequently increased load bearing., Results: Due to the smaller incision and the associated lower soft tissue trauma, the risk of wound healing complications can be reduced. Radiographic and functional outcomes are comparable to the outcomes of calcaneal fractures treated via the extended lateral approach., (© 2023.

• O'Driscoll described linking the distal humerus columns to create a stable construct which can withstand early rehabilitation. • An interlocking beam linking the medial & lateral plates provides greater stability compared to a similar unlinked construct. • The beam's double supported design resists cantilever bending and provides robust compression of the fractured fragments. Concerning rates of nonunion in articular distal humerus fractures indicate an unsolved problem. The fixation principles of O'Driscoll describe linking the fractured articular segment to the distal humerus columns with compression screws which creates a stable fixed angle construct. A novel device has been introduced which utilizes an interlocking beam through the articular segment to connect the distal aspect of the medial and lateral plates, creating a linked construct. We sought to evaluate the stability of this linked construct using an articular model of distal humerus fracture. Ten matched pair specimens of 65 years of age or older were randomized to the use (LB group) or non-use (NLB group) of an interlocking beam to link the medial and lateral locking plates in fixation of an AO Type C3 fracture model. Outside of the linking beam, fixation between the matched pairs was consistent using 2.7 mm locking screws distally with fixed trajectories and +/- 2 mm lengths. Mean stiffness was 273 Newtons/mm in the LB group and 225 Newtons/mm in the NLB group (p = 0.001). Mean maximum displacement was 0.28 in the LB group and 0.93 mm in the NLB group (p = 0.006). Mean load to failure was 277 pounds in the LB group and 280 pounds in the NLB group (p = 0.94). Our results indicate that an interlocking beam which links the medial and lateral plates provides greater stability compared to a similar construct without an interlocking beam. We attribute this finding to the beam's double supported design which resists cantilever bending and provides robust compression of the fractured fragments. [ABSTRACT FROM AUTHOR]

Plastic deformities usually occur in skeletally immature bones not completely ossified due to longitudinal forces on their distal ends, especially the forearm and lower legs. Pediatric lateral humeral condylar fractures (LHCFs) constitute the second most common intra-articular fracture in the upper extremity. Nevertheless, plastic deformities accompanied by other traumatic injuries, including LHCFs, are atypical and rare. This study presents an exceedingly rare case of the concurrence of a plastic deformity and an ipsilateral fracture of the lateral condyle of the humerus in a 6-year-old Persian boy. The 6-year-old Persian injured boy referred to orthopedic clinic with an obvious deformity in the right upper limb with a limited motion range in the ipsilateral elbow. The patient underwent open-fixation surgery for LHCF fixation and suitable maneuvers to rectify the ulnar plastic deformity. Our findings indicated an acceptable outcome for this approach. His injured limb was reformed without deformities, and the complete union of the fractured area was accomplished eight weeks after surgery. The case is remarkable as reminding that we have to care concomitant "minor" injuries to the main fracture and to correctly treat them. Furthermore, open fixation surgery for LHCF rectification before fixing the ulnar deformity with the aid of a suitable maneuver led to good outcome and acceptable rehabilitation in a case of concurrent ulnar plastic deformity and an ipsilateral fracture of the external condyle of the humerus. Our approach helps to avoid further tissue damage and prevent the 2-stage surgical process. • Reminding that we have to care concomitant "minor" injuries to the main fracture and to correctly treat them. • In a concurrent ulnar plastic deformity and ipsilateral LHCF,Open fixation for LHCF correction led to acceptable rehabilitation • This approach helps to avoid further tissue damage and prevent the 2-stage surgical process.

Post-traumatic osteoarthritis (PTOA) develops secondary to a joint injury and accounts for 12 % of all osteoarthritis. These injuries, often of the lower extremity joints, occur due to trauma or accidents related to athletic or military activities. They primarily affect younger individuals although PTOA can occur across the spectrum of age. Pain and functional disability caused by PTOA confer a heavy economic toll on patients, in addition to detrimentally affecting their quality of life. Both high energy injuries that cause articular surface fracture with or without subchondral bone disruption and low-energy injuries involving joint dislocations or ligamentous injury cause PTOA, albeit through different mechanisms. Regardless, chondrocyte death, mitochondrial dysfunction, reactive oxygen species production, subchondral bone remodeling, inflammation and cytokine release in the cartilage and synovium play integral roles in the pathogenesis of PTOA. Evolving surgical methods are focused on stabilizing articular surface and joint structure congruity. However, to date there are no disease modifying medical therapies against PTOA. Increased recent understanding of the pathogenesis of the subchondral bone and synovial inflammation as well as that of chondrocyte mitochondrial dysfunction and apoptosis have led to the investigation of new therapeutics targeting these mechanisms to prevent or delay PTOA. This review discusses new advances in our understanding of cellular mechanisms underlying PTOA, and therapeutic approaches that are potentially effective in reducing the self-propagating cycle of subchondral bone alterations, inflammation, and cartilage degradation. Within this context, we focus therapeutic options involving anti-inflammatory and anti-apoptotic candidates that could prevent PTOA., Competing Interests: Julian Emerson Dilley, Margaret Anne Bello and Uma Sankar have no financial disclosures or conflicts of interest in relation to this study.

Objective: To compare the effectiveness of open reduction and internal fixation with plate and closed reduction and internal fixation with Kirschner wire (K-wire) in the treatment of intra-articular displaced calcaneal fractures in older children., Methods: A clinical data of 35 older children (37 feet) with intra-articular displaced calcaneal fractures who were admitted between November 2014 and November 2020 and met the selection criteria were retrospectively analyzed. Among them, 19 cases (20 feet) underwent open reduction and internal fixation with plate (plate group), and 16 cases (17 feet) underwent closed reduction and internal fixation with K-wire (K-wire group). There was no significant difference in gender, age, cause of injury, side and type of fracture, and time from injury to admission, and preoperative calcaneal Gissane angle and Böhler angle ( P >0.05). The postoperative calcaneal Gissane angle, Böhler angle, complications, and fracture healing were compared between the two groups. The ankle function was evaluated based on the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scoring system., Results: Incision necrosis occurred in 1 foot in the plate group after operation, which healed after symptomatic treatment; the other incisions in the two groups healed by first intention. All children were followed up 12-39 months (mean, 19 months). X-ray films showed that the fractures in both groups healed; the healing time was (2.65±0.71) months in the plate group and (2.24±1.38) months in the K-wire group respectively, with no significant difference ( t =1.161, P =0.253). At last follow-up, the calcaneal Gissane angle and Böhler angle returned to normal; and the difference between pre- and post-operation in the two group was significant (P <0.05), but there was no significant difference between the two groups in the difference between before and after operation ( P >0.05). In the plate group, the plate was removed at 11-22 months after operation (mean, 16.8 months). At last follow-up, the AOFAS ankle-hindfoot score in the plate group was 91.2±5.1, which was significantly higher than that in the K-wire group (86.9±6.1) ( t =2.316, P =0.027). The ankle function was rated as excellent in 15 feet, good in 4 feet, and fair in 1 foot in the plate group, and excellent in 14 feet and good in 3 feet in the K-wire group, and the difference between the two groups was not significant ( Z =1.712, P =0.092)., Conclusion: For intra-articular displaced calcaneal fracture in older children, the open reduction and internal fixation with plate and closed reduction and internal fixation with K-wire can achieve good effectiveness, but the former has better recovery of ankle function.

Stabilization for displaced dorsoulnar fragments in distal radius fractures is challenging to treat with conventional volar locking plates alone. The integrated compression screw combined with a volar locking plate has been introduced as an additional tool to stabilize the dorsoulnar fragment and has been reported to work effectively. However, the compression screw is unable to stabilize a comminuted dorsal ulnar fragment; therefore, it is necessary to consider using an additional dorsal plate. We have developed a modified surgical technique to stabilize a comminuted dorsal intra-articular fragment by combining the integrated compression screw with a mini-plate as a washer or a buttress.
