Abstract
Ankle fractures represent up to 9% of all fractures, with an increased incidence in the elderly population. Among these fractures, isolated fractures of the lateral malleolus are the most common, representing 65-70% of all cases. The therapeutic decision-making primarily relies on the stability of the ankle ring, considering it stable if affected at one point and unstable if two or more points are affected. Surgical treatment focuses on restoring the length of the fibula, joint reconstruction, stabilizing the syndesmosis, and providing a stable fixation. It is crucial to rule out associated injuries that may influence therapeutic management. This article reviews the evaluation and management of lateral malleolus fractures, proposes a decision-making algorithm, and examines several fibular fixation options.

Chin J Traumatol 2024:S1008-1275(24)00069-5. [PMID: 38937167 DOI: 10.1016/j.cjtee.2024.06.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 05/26/2024] [Accepted: 06/02/2024] [Indexed: 06/29/2024] Open
Abstract
PURPOSE To assess the relationship between dislocation and functional outcomes in supination-external rotation (SER) ankle fractures. METHODS A retrospective case series study was performed on patients with ankle fractures treated surgically at a large trauma center from January 2015 to December 2021. The inclusion criteria were young and middle-aged patients of 18-65 years with SER ankle fractures that can be classified by Lauge-Hansen classification and underwent surgery at our trauma center. Exclusion criteria were serious life-threatening diseases, open fractures, fractures delayed for more than 3 weeks, fracture sites ≥2, etc. Then patients were divided into dislocation and no-dislocation groups. Patient demographics, injury characteristics, surgery-related outcomes, and postoperative functional outcomes were collected and analyzed. The functional outcomes of SER ankle fractures were assessed postoperatively at 1-year face-to-face follow-up using the foot and ankle outcome score (FAOS) and American orthopedic foot and ankle society score and by 2 experienced orthopedic physicians. Relevant data were analyzed using SPSS version 22.0 by Chi-square or t-test. RESULTS During the study period, there were 371 ankle fractures. Among them, 190 (51.2%) were SER patterns with 69 (36.3%) combined with dislocations. Compared with the no-dislocation group, the dislocation group showed no statistically significant differences in gender, age composition, fracture type, preoperative complications with diabetes, smoking history, preoperative waiting time, operation time, and length of hospital stay (all p > 0.05), but a significantly higher Lauge-Hansen injury grade (p < 0.001) and syndesmotic screw fixation rate (p = 0.033). Moreover, the functional recovery was poorer, revealing a significantly lower FAOS in the sport/rec scale (p < 0.001). Subgroup analysis showed that among SER IV ankle fracture patients, FAOS was much lower in pain (p = 0.042) and sport/rec scales (p < 0.001) for those with dislocations. American orthopedic foot and ankle society score revealed no significant difference between dislocation and no-dislocation patients. CONCLUSION Dislocation in SER ankle fractures suggests more severe injury and negatively affects functional recovery, mainly manifested as more pain and poorer motor function, especially in SER IV ankle cases.

Abstract
BACKGROUND Ankle fractures are frequent, and despite numerous publications on their treatment and outcome, there is a lack of precise data on the functional results in young, healthy and physically active patients. We hypothesized that patients who underwent open reduction and internal fixation (ORIF) for simple ankle fractures would have similar function compared to a healthy control group, whereas patients with complex fractures will have significant functional deficits. Furthermore, we postulate that there is a discrepancy between the radiological and the functional outcomes. METHODS A set of specific provocation tests was developed to evaluate the postoperative possibility of weight bearing, stop-and-go activities and range of motion. In combination with three questionnaires and a radiographic evaluation, the true functional outcome and the possibility of participating in sporting activities were investigated and compared with those of an age- and sex-matched control group. RESULTS A significant impairment was found in unilateral and simple ankle fractures. This impairment increased in tests including stop-and-go activities in combination with load bearing and with the complexity of the fractures. Concerning the subjective outcome, there was a significant adverse effect for daily activities without any difference in preoperative or postoperative sporting activity between the groups. No difference was found in the radiological assessment. CONCLUSIONS Both simple and complex ankle fractures treated with ORIF have a significant and long-lasting impact on functional outcome in young and active patients. The radiological result is not associated with a good functional outcome. TRIAL REGISTRATION BASEC-Nr. 2018 - 01124.

Abstract
BACKGROUND Unstable fractures often necessitate open reduction and internal fixation (ORIF), which generally yield favourable outcomes. However, the impact of surgical trainee autonomy on healthcare quality in these procedures remains uncertain. We hypothesized that surgery performed solely by residents, without supervision or participation of an attending surgeon, can provide similar outcomes to surgery performed by trauma or foot and ankle fellowship-trained orthopaedic surgeons. METHODS A single-center cohort of an academic level-1 trauma center was retrospectively reviewed for all ankle ORIF between 2015 and 2019. Data were compared between surgery performed solely by post-graduate-year 4 to 6 residents, and surgery performed by trauma or foot and ankle fellowship-trained surgeons. Demographics, surgical parameters, preoperative and postoperative radiographs, and primary (mortality, complications, and revision surgery) and secondary outcome variables were collected and analyzed. Univariate analysis was performed to evaluate outcomes. RESULTS A total of 460 ankle fractures were included in the study. Nonoperative cases and cases operated by senior orthopaedic surgeons who are not trauma or foot and ankle fellowship-trained orthopaedic surgeons were excluded. The average follow-up time was 58.4 months (SD ± 12.5). Univariate analysis of outcomes demonstrated no significant difference between residents and attendings in complications and reoperations rate (p = 0.690, p = 0.388). Sub-analysis by fracture pattern (Lauge-Hansen classification) and the number of malleoli involved and fixated demonstrated similar outcomes. surgery time was significantly longer in the resident group (p < 0.001). CONCLUSION The current study demonstrates that ankle fracture surgery can be performed by trained orthopaedic surgery residents, with similar results and complication rates as surgery performed by fellowship-trained attendings. These findings provide valuable insights into surgical autonomy in residency and its role in modern clinical training and surgical education. LEVEL OF EVIDENCE Level III - retrospective cohort study.

Abstract
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.

Abstract
INTRODUCTION Ankle fractures rank as the second most common lower limb fractures, and surgical intervention is essential for unstable ankle fractures. The use of ankle arthroscopy in such cases offers several advantages. This study aim is to assess whether arthroscopy influenced on complication rates in 171 ankle fractures treated with arthroscopic assistance. METHODS This retrospective epidemiological analysis encompassed adult ankle fractures between December 2018 and December 2021. Initially, 173 patients were considered, but two were excluded, leaving a final sample of 171 patients. Postoperative complications were categorized as major or minor. RESULTS The study included 171 patients with surgically treated ankle fractures assisted by arthroscopy, comprising 76 females and 95 males, with an average age of 41.9 years. Syndesmosis injuries were treated in all diagnosed cases (55.0%), and deltoid ligament injuries received attention when identified (33.7%). Arthroscopic techniques were preferred over open techniques (47.4%). Ten patients experienced complications, consisting of 2 major and 8 minor complications (5.8%). DISCUSSION Our study's epidemiological findings align with prior literature, demonstrating that intra-articular injuries accompany 63% to 79% of ankle fractures. Arthroscopy allows for both diagnosis and treatment within the same procedure, including joint lavage to reduce inflammation. We diagnosed 57 deltoid injuries and identified a statistical relationship between chondral, syndesmotic, and deltoid ligament injuries. Infection is a common complication in ankle fracture surgery, with rates ranging from 1.44% to 16%. Our study yielded a 5.8% complication rate, comprising 1.2% major and 4.6% minor complications. Patients undergoing ORIF with arthroscopic assistance had a lower prevalence of infection. CONCLUSION The use of arthroscopic assistance in the surgical treatment of ankle fractures does not increase the overall complication rate. LEVEL OF EVIDENCE IV.

Abstract
OBJECTIVE The utility of routine post-operative imaging in clinically asymptomatic patients is unclear. We sought to determine how frequently X-rays following operatively treated ankle fractures result in a change in management. DESIGN Retrospective cohort study conducted with hospital electronic health record SETTING: Single level 1 trauma center in major urban city. PATIENTS/PARTICIPANTS 193 patients with operatively treated ankle fractures at our institution between January 2020 and December 2021. MAIN OUTCOME MEASURES Patient radiographs were categorized as surveillance X-rays and clinically indicated X-rays. Changes in management were defined as alteration in follow-up, deviation from standard post-operative protocols, or revision surgery. A logistic regression was performed looking at factors predicting whether an X-ray changes management. A cost analysis was also performed looking at the financial implications of asymptomatic surveillance of ankle fractures. RESULTS 438 post-operative X-rays were found and included in analysis. Of these, 391 were considered surveillance X-rays and 47 clinically indicated. 23 X-rays were determined to have resulted in changes in management (18 clinically indicated, 5 taken in asymptomatic patients). The number of management changing X-rays was significantly higher in the clinically indicated group (p < 0.0001). The only factor associated with whether an X-ray changed management was whether the patient was symptomatic at the visit (p < 0.0001). Asymptomatic surveillance X-rays cost our institution 21,825.62 USD per year. CONCLUSIONS Radiographs in clinically asymptomatic patients with operatively managed ankle fractures have a low likelihood of changing management. Such imaging represents costs to the healthcare system, increased time for patients during clinic visits, and radiation exposure. The use of screening radiographic studies remains commonplace because the risk of delayed diagnosis is great, and the goal of any surgeon should be the swift identification of complications in order to minimize patient morbidity. Future surveillance protocols should consider the findings of this and other studies on the use of screening radiographs and strike a careful balance between minimizing unnecessary imaging, maximizing early complication detection, and ensuring a personalized approach towards patient-level factors to optimize care and efficiency for both patient and health system.

Abstract
Postoperative care of ankle fractures treated with open reduction and internal fixation (ORIF) is a debated topic. A meta-analysis of Randomized Controlled Trials was conducted with the aim of comparing early mobilization and weightbearing to traditional postoperative protocols. A systematic search of electronic databases was conducted according to the PRISMA guidelines. Only randomized clinical trials were included. Data about clinical outcome, time to return to work and complications were extracted and summarized. Meta-analyses were performed. Twenty studies for a total of 1328 patients were included. Early mobilization was compared to immobilization in 724 patients: the two groups did not significantly differ in terms of short- and long-term clinical outcome (p = 0.08 and p = 0.41, respectively). However, early mobilization resulted to be significantly associated with faster return to work (p = 0.047). Early weightbearing was compared to nonweightbearing in 1088 patients. While the clinical difference between the two groups was not significant at short term (p = 0.08), it was significant at long term (p = 0.002). No other significant differences, in particular regarding complications, were highlighted between different groups. Early motion, early weightbearing and traditional postoperative protocols are all safe strategies after ORIF for unstable ankle fractures. Early mobilization is significantly associated with faster return to work and early weightbearing improves long term clinical outcome.Level of evidence: I.

Abstract
PURPOSE There are two main surgical fixation methods for the posterior malleolar fractures (PMFs), the anterior-to-posterior (AP) screws or via the posterolateral (PL) approach utilizing a buttress plate. This review aims to compare the clinical outcome between the AP screw fixation and the PL plate fixation for treating PMFs. METHODS We searched all relevant publications about PMFs treated with AP screws or PL plates through electronic databases including the PubMed, the Cochrane Library, the Embase, the Wiley online library and the Web of Science. The meta-analysis was conducted to evaluated clinical outcomes including reduction quality, post-operative function and complications. RESULTS Six studies (one single randomized controlled trial and five retrospective cohort studies) were enrolled. 172 patients underwent AP screw fixation and 214 patients underwent PL plate fixation with a total of 386 patients (169 males and 217 females). The PL plating group yielded better AOFAS scores(MD = 6.97, 95 % CI=[4.68, 9.27], P<0.00001, I2 =0 %) and was more likely to achieve excellent anatomical reduction(OR=5.49, 95 % CI=[1.06, 28.42], P = 0.04, I2 =80 %). No differences were found in the bad reduction quality, incidences of complications (arthritis, neuralgia, superficial wound healing problems and implant failure), the walking VAS scores and the dorsiflexion restriction degrees. CONCLUSION We suggest that the PL plate fixation method has the clinical benefit of achieving anatomical reduction and better AOFAS scores over the AP screw fixation for treating PMFs. No differences were found in the incidences of complications ( arthritis, neuralgia, superficial wound healing problems and implant failure), the walking VAS scores and the dorsiflexion restriction degrees. The posterior approach and the direct reduction are recommended for the treatment of the PMFs. LEVEL OF CONFIDENCE Ⅱb.

Abstract
BACKGROUND Ankle fractures are prevalent injuries that necessitate precise diagnostic tools. Traditional diagnostic methods have limitations that can be addressed using machine learning techniques, with the potential to improve accuracy and expedite diagnoses. METHODS We trained various deep learning architectures, notably the Adapted ResNet50 with SENet capabilities, to identify ankle fractures using a curated dataset of radiographic images. Model performance was evaluated using common metrics like accuracy, precision, and recall. Additionally, Grad-CAM visualizations were employed to interpret model decisions. RESULTS The Adapted ResNet50 with SENet capabilities consistently outperformed other models, achieving an accuracy of 93%, AUC of 95%, and recall of 92%. Grad-CAM visualizations provided insights into areas of the radiographs that the model deemed significant in its decisions. CONCLUSIONS The Adapted ResNet50 model enhanced with SENet capabilities demonstrated superior performance in detecting ankle fractures, offering a promising tool to complement traditional diagnostic methods. However, continuous refinement and expert validation are essential to ensure optimal application in clinical settings.

Abstract
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
INTRODUCTION Results of operative fixation for ankle fractures had been suboptimal, with cases of posttraumatic osteoarthritis occurring following the surgeries. Intra-articular injuries have been suggested as the cause of this problem. This case report aims to present an ankle pilon fracture Ruedi Allgower type II case treated with percutaneous fixation and arthroscopy evaluation. PRESENTATION OF CASE Female, 17 years old, complained of pain and swelling at the right ankle. The physical examination revealed swelling, deformity, tenderness, and limited range of motion at the right ankle. The radiological examination showed a Ruedi Allgower type II pilon fracture with right ankle dislocation. The patient underwent closed reduction, arthroscopy to evaluate her right ankle and percutaneous internal fixation. The post-surgery evaluation showed a stable ankle. DISCUSSION Patients undergoing ankle fracture surgery may benefit from ankle arthroscopy because it may increase visualization of articular reductions, assess and repair cartilage and ligament damage, remove loose bodies, decrease soft tissue exposure, preservative vascularity, and evaluate syndesmosis. Moreover, rapid arthroscopic evaluation has a low complication rate. The ability of arthroscopy to improve syndesmotic instability diagnosis suggests that arthroscopy may play a significant role in managing ankle fractures. CONCLUSION Arthroscopy-assisted internal fixation provides more benefits and information as a single case report, and more studies are warranted; regarding patients' intra-articular injuries, preventing future complications, such as posttraumatic osteoarthritis.

Abstract
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.

Cost analysis and clinical outcomes of anatomic pre-contoured locking versus conventional plates for distal fibula ankle fractures. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:959-965.

Abstract
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
Ankle fracture is the third most prevalent fracture in older adults. Wound dehiscence is the most frequent complication. Our objective is to determine the operative wound complication rate in patients with unstable ankle fracture in whom a prophylactic simple fasciocutaneous advancement was used. METHODS Prospective registry of patients with unstable ankle fracture, in whom a prophylactic fasciocutaneous advancement was performed between August 2020 and July 2021. Demographic variables, time spent in performing the flap, cost of osteosynthesis, minor and major complications of the surgical wound, readmission or reoperation were registered. RESULTS 42 older adults with ankle fracture were included. Median age 69 (60-94). 31% diabetics and 21.5% active smokers. A 40% trimalleolar fracture pattern. There were 7% of superficial complications of the surgical wound. No major complications, no reoperations. CONCLUSIONS Prophylactic fasciocutaneous advancement at the beginning of traumatological surgery is technically simple, reproducible, cheap and with low complications.

Abstract
INTRODUCTION No comprehensive treatise on the early history of fractures of posterior malleolus (PM) has yet been published, and many substantial discoveries have fallen into oblivion-particularly if not having been published in English originally. MATERIALS AND METHODS Literature search was performed in original publications and historical sources. RESULTS Early history of PM fractures from their first description up to the beginnings of their operative treatment may be divided into three basic periods, covering the era between 1828 and 1940. In the pre-radiological period (1828-1895), description of PM injuries was based merely on the autopsy findings in deceased patients. The first mentions of this injury were published by the British authors. In the radiologic period (1899-1916), the x-ray examination started a revolution also in diagnostics of ankle fractures, with the first radiographs performed as early as in 1899. Radiographic examination had subsequently become an integral part of the diagnostics of these injuries and initiated a number of significant studies of PM fractures. The first detailed mention of a PM injury may be found in the French and German literature. The period of early operative treatment (1918-1940), i.e., open reduction and internal fixation of PM, was started by the younger post-WWI generation, primarily the French surgeons, represented by Gaston Picot. His operative technique and the first six cases treated operatively between 1918 and 1921 were described in 1921 by Edouard Huc. Picot himself published his technique in great detail in 1923. CONCLUSION The early history of diagnostics and treatment of PM fractures witnesses the remarkable body of knowledge gathered about that topic by numerous visionary surgeons predominantly French and German surgeons immediately before and after World War I. They substantially contributed to the radiological examination and operative treatment of this injury.

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.

Abstract
PURPOSE Tibial shaft spiral fractures and fractures of the distal third of the tibia (AO:42A/B/C and 43A) frequently occur with non-displaced posterior malleolus fractures (PM). This study investigated the hypothesis that plain X-ray is not sufficient for a reliable diagnosis of associated non-displaced PM fractures in tibial shaft spiral fractures. METHODS 50 X-rays showing 42A/B/C and 43A fractures were evaluated by two groups of physicians, each group was comprised of a resident and a fellowship-trained traumatologist or radiologist. Each group was tasked to make a diagnosis and/or suggest if further imaging was needed. One group was primed with the incidence of PM fractures and asked to explicitly assess the PM. RESULTS Overall, 9.13/25 (SD ± 5.77) PM fractures were diagnosed on X-ray. If the posterior malleolus fracture was named or a CT was requested, the fracture was considered "detected". With this in mind, 14.8 ± 5.95 posterior malleolus fractures were detected. Significantly more fractures were diagnosed/detected (14 vs. 4.25/25; p < 0.001/14.8 vs. 10.5/25; p < 0.001) in the group with awareness. However, there were significantly more false positives in the awareness group (2.5 vs. 0.5; p = 0.024). Senior physicians recognized slightly more fractures than residents (residents: 13.0 ± 7.79; senior physicians: 16.5 ± 3.70; p = 0.040). No significant differences were demonstrated between radiologists and trauma surgeons. The inner-rater reliability was high with 91.2% agreement. Inter-rater reliability showed fair agreement (Fleiss-Kappa 0.274, p < 0.001) across all examiners and moderate agreement (Fleiss-Kappa 0.561, p < 0.001) in group 2. CONCLUSION Only 17% of PM fractures were identified on plain X-ray and awareness of PM only improved diagnosis by 39%. While experiencing improved accuracy, CT imaging should be included in a comprehensive examination of tibial shaft spiral fractures. LEVEL OF EVIDENCE II. Diagnostic prospective cohort study.

Abstract
PURPOSE Electric scooters (e-scooters) have become an increasingly popular mode of public transportation in recent years. As the incidence of related injuries rises, it is important to understand specific fracture patterns unique to e-scooters and electric bikes (e-bikes) to help guide management. The purpose of this study was to review the prevalence and describe specific fracture patterns of e-scooter and e-bike related injuries at the busiest level 1 trauma center in the borough of Manhattan. METHODS Chart review to determine mechanism of injury was performed on all patients for whom an orthopedic consult was requested from 1/1/2021 to 12/31/2021. All patients whose injuries were sustained due to an e-scooter or e-bike were further reviewed for demographics, injury characteristics including fracture pattern, and definitive injury management. Any patients who had an orthopedic consult placed for a reason other than an acute injury were excluded. Descriptive statistics are reported as frequency (percentage) for categorical variables and means for continuous variables. RESULTS Of the 1815 orthopedic consults requested, 1357 (74.8%) were for acute injury management. Of those with acute injuries, 119 (8.8%) sustained 136 e-scooter or e-bike related injuries. There were 92 (77.3%) males at an average age of (33.8 ± 15.7) years. Approximately one-fifth of all patients presented in June 2021 (26, 21.8%). There was a 9.2% rate of open fractures. The 136 injuries were evenly split between the upper and lower extremities, with 57 (47.9%) upper extremity, 57 (47.9%) lower extremity injuries, and 5 (4.2%) concomitant upper and lower extremity injuries. The most common fracture patterns were ankle fractures (16, 11.7%), followed by tibial shaft (14, 10.2%), tibial plateau (13, 9.5%), and radial head fractures (11, 8.0%). There was a 33.3% incidence of associated posterior malleolar fractures in the spiral tibial shaft fractures, 31.0% of posterior malleolar involvement and 18.8% of isolated vertical medial malleolar fractures in the ankle fractures, and 61.5% of posterior comminution in the tibial plateau fractures. CONCLUSION E-scooter and e-bike related injuries have a high incidence of tibial shaft fractures, ankle fractures, tibial plateau fractures, and radial head fractures. There should be a high index of suspicion for posterior and medial involvement in lower extremity fractures sustained due to e-scooter or e-bikes. Identifying specific fracture patterns seen in e-scooter and e-bike related mechanisms will help guide management of these injuries.

Abstract
INTRODUCTION Ankle fractures are one of the most frequent injuries managed by any trauma surgeon. Literature has shown that adequate reduction is of utmost importance to achieve satisfactory functional outcomes. However, malreduction rates remain high worldwide. The objective of the present study is to evaluate the quality of ankle fracture reduction in two major trauma centers in a large Brazilian city and to analyze the factors associated with malreduction METHODS: Epidemiologic data of 382 patients (189 men; 193 women) aged between 7 and 87 years who underwent osteosynthesis of the ankle in two trauma centers in a large Brazilian city. Electronic clinical records, preoperative and immediate postoperative radiographs in anteroposterior (AP), lateral and mortise views were evaluated. Pettrone's criteria were used to evaluate the quality of ankle fractures reduction. All radiographs were independently evaluated by two foot and ankle senior surgeons RESULTS: Overall, malreduction rate was 22.2%. Forty-seven (55.2%) fractures classified as malreduced had medial malleolar displacement The results showed three factors that significantly affected the quality of reduction (p<0.05), patients over 60 years, open fractures and fracture-dislocations. Patients aged over 60 years were twice more likely to have poor reduction of ankle fractures than younger ones. The risk of poor fracture reduction among those individuals with open fractures is 2.15 times greater than among patients with closed injuries. Fracture-dislocation imposed a 2.7 higher risk for malreduction DISCUSSION: We found a malreduction rate below most series previously published. Further results agree with the literature. Elderly people aged over 60 years, fracture dislocations and open fractures are associated with worse results, influencing the quality of the reduction, clinical outcomes, and the development of post-traumatic arthrosis CONCLUSION: Ankle fractures malreduction are associated with higher age, open fractures, and fracture-dislocations.

Abstract
BACKGROUND Ankle fractures are commonly treated with non-surgical or surgical (preferably ORIF) approaches based on fracture characteristics. The postoperative care regimens vary widely, and the impact of very early mobilization on complications and reoperation rates in ankle fractures treated with ORIF remains unclear. METHODS A retrospective analysis was conducted on ankle fractures treated between January 2014 and November 2020. Demographic and fracture characteristic data were collected. Very early prescription of range of motion exercises was defined as initiation within the first week after surgery, typically between the second and seventh postoperative day. Complications, reoperations, and time to these events were analyzed. Kaplan Meier survival analysis was performed to assess the risk of complications with very early mobilization. RESULTS A total of 299 patients met the inclusion criteria. The cohort included 83 unimalleolar, 77 bimalleolar, and 138 trimalleolar fractures. Of the patients, 116 (38.8%) underwent very early range of motion. Complications occurred in 45 events among 39 patients (13%), with 16 events (41%) in the very early range of motion group. Reoperations were required for 23 patients (3.67% of the cohort). No statistically significant differences were found in the analysis of complications, with a hazard ratio (HR) of 1.17, and in the adjusted analysis with an HR of 1.12. Similarly, the reoperation analysis showed no significant differences, with an HR of 0.85 and 0.68 in the adjusted analysis. CONCLUSION Very early prescription of range of motion exercises in ankle fractures treated with ORIF is a safe approach, as it does not increase the rates of complications or reoperations compared to early or late mobilization. This study supports the use of very early mobilization as a rehabilitation method for ankle fractures.

Abstract
Bosworth fracture and dislocation is relatively rare, accounting for about 1% of ankle fractures. It is characterized by the proximal fibula fracture embedded in the posterolateral distal tibia. Due to an insufficient understanding of this fracture, it is easy to cause missed diagnosis and misdiagnosis in clinical practice. Due to the insertion of the fracture, it is challenging to perform closed reduction, and improper treatment is easy to cause complications. Surgical treatment is recommended for this type of fracture. In order to improve the understanding of orthopedic surgeons about Bosworth fracture and dislocation, this paper reports the diagnosis and treatment of 2 cases of Bosworth fracture and dislocation, and reviews the literature on Bosworth fracture's mechanism, diagnosis, classification, complications, and treatment options in recent years.

Abstract
INTRODUCTION Ankle fractures comprise 9% of all fractures and are among the most common fractures requiring operative management. Open reduction and internal fixation (ORIF) with plates and screws is the gold standard for the treatment of unstable, displaced ankle fractures. While performing ORIF, orthopaedic surgeons may choose from several fixation methods including locking versus nonlocking plating and whether to use screws or suture buttons for syndesmotic injuries. Nearly all orthopaedic surgeons treat ankle fractures but most are unfamiliar with implant costs. No study to date has correlated the cost of ankle fracture fixation with health status as perceived by patients through patient reported outcomes (PROs). The purpose of this study was to determine whether there is a relationship between increasing implant cost and PROs after a rotational ankle fracture. METHODS All ankle fractures treated with open reduction internal fixation (ORIF) at a level I academic trauma center from January 2018 to December 2022 were identified. Inclusion criteria included all rotational ankle fractures with a minimum 6-month follow-up and completed 6-month PRO. Patients were excluded for age <18, polytrauma and open fracture. Variables assessed included demographics, fracture classifications, Foot and Ankle Ability Measure-Activities of Daily Living (FAAM-ADL) score, implant type, and implant cost. RESULTS There was a statistically significant difference in cost between fracture types (p < 0.0001) with trimalleolar fractures being the most expensive. The mean FAAM-ADL score was lowest for trimalleolar fractures at 78.9, 95% CI [75.5, 82.3]. A diagnosis of osteoporosis/osteopenia was associated with a decrease in cost of $233.3, 95% CI [-411.8, -54.8]. There was no relationship between syndesmotic fixation and implant cost, $102.6, 95% CI [-74.9, 280.0]. There was no correlation between implant cost and FAAM-ADL score at 6 months (p = 0.48). CONCLUSIONS The utilization of higher cost ankle fixation does not correlate with better FAAM-ADL scores. Orthopaedic surgeons may choose less expensive implants to improve the value of ankle fixation without impacting patient reported outcomes.

Abstract
OBJECTIVES The aim of the study was to propose a classification system of posterior malleolar fractures by fracture lines with the use of CT scans, including 3D CT reconstruction, which can better understand morphological characteristics, analyze the mechanism and guide the surgeon to choose the optimal approach and fixation. METHODS Patients with OTA/AO type 44 fractures involving the posterior malleolus and preoperative CT scans were included. We retrospectively analyzed 128 consecutive patients with posterior malleolar fractures from January 2013 to December 2019 at our institution. CT data were loaded into Mimics software (V20.0, Materialize), in which 3D CT reconstruction, morphological analysis and data measurements were made. RESULTS Based on the number of fracture lines in 128 consecutive patients, posterior malleolar fractures were classified into three types: type 1 with a single fracture line, type 2 with double fracture lines and type 3 with multiple fracture lines. According to the distribution of the fracture line, type 1 was divided into types 1A, 1B and 1C, and type 2 was divided into types 2A, 2B and 2C. The fracture line from the fibular notch to the posterior rim of the distal tibia was defined as type 1A, and the fracture line to the medial malleolus was defined as type 1B. Type 1C was a small fragment in the posterior rim of the distal tibia. Type 2A was regarded as type 1A with type 1C. It was considered type 2B because another fracture line started from the fracture line of type 1A and extended to the medial malleolus. In type 2C, we could see that the double fracture lines were all from the fibular notch to the posterior rim of the distal tibia and did not cross. Type 3 fractures were comminuted fractures with multiple fracture lines. CONCLUSION The morphology of posterior malleolar fractures, involvement of the fibular notch, or the medial malleolus can be obviously assessed by our classification system. We found the relation of the injury mechanism between type 1 and type 2 by comparing the area of the fragment. We have indicated that each type of fracture corresponds to its associated injury mechanism and which surgical approach and fixation can be chosen.
