Abstract
Purpose The study aimed to establish and subsequently improve the rate of stability assessments of fractures with uncertain stability and the impact on the avoidance of potentially unnecessary surgery. Methods Two independent audit cycles were conducted from October 2019 to May 2020. All patients had closed isolated lateral malleolar fractures at the level of the tibiotalar syndesmosis involving skeletally mature bone. A stability-based management protocol was introduced, incorporating an education programme and management guideline. Results 75 ankles fractures were included. In the initial audit cycle, 13 patients did not undergo stability X-rays within 2 weeks of injury. Interestingly, only one stability assessment was performed for five operated ankles in the first audit, versus a 100% compliance rate in the second cycle. We observed more accurate documentation following education and awareness of clinical importance. Conclusion By implementing a stability-based management guideline, there was an improvement in compliance with guidance towards stability assessments of ankle fractures. This potentially led to the avoidance of unnecessary surgery on fractures where stability assessments supported non-operative management.

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

Abstract
Posterior malleolus fractures are frequent injuries, present in 7-44% of all ankle fractures. The objective of this study is to review the evidence to indicate the fixation of this fracture and to choose the appropriate surgical approach. The classic indications for fixation were fragment size greater than 25-30% of the articular surface and displacement greater than 2mm. However, current evidence suggests that, rather than size, factors such as syndesmotic instability, intra-articular step-off greater than 1-2mm, plafond impaction and the presence of intercalary fragments should be considered. When comparing the different surgical approaches, the literature supports the use of posterior approaches and reserves the recommendation of the traditional approach for exceptional cases. For the treatment of this injury it is essential to know the anatomy of the ankle and to consider all the factors described above, in addition to the presence of concomitant injuries.

Variation in posterior fragment fixation in the Netherlands: a nationwide study. Eur J Trauma Emerg Surg 2023; 49:317-326. [PMID: 36018372 DOI: 10.1007/s00068-022-02066-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2019] [Accepted: 07/16/2022] [Indexed: 11/03/2022]
Abstract
PURPOSE The treatment of the posterior fragment in trimalleolar fractures differs from hospital to hospital in the Netherlands. A nationwide survey was performed to evaluate the fixation criteria and practice variation. METHODS An online cross-sectional survey amongst (orthopaedic) trauma surgeons was performed in the Netherlands. It consisted of three sections: a general section, a section showing preoperative images of six cases and a section with postoperative images of nine cases. RESULTS A total of 151 surgeons completed the online survey. 45% of the respondents indicated that they fixated the posterior fragment if smaller than 25% of the intra-articular surface. 48% preferred an open posterior approach to fixate the posterior fragment. There was good consensus in treatment for the two cases with Bartonicek type 4 fractures (operative treatment in 73 and 72% respectively). Little consensus was found for Bartonicek type 2 and 3 fractures (88% opted for operative treatment in one case, but 89% for conservative treatment in the second case). Reoperation was mostly considered in cases with a step-off of more than 1 mm (by 33-38% of the respondents). There was great variation in the choice of treatment if only the size of the posterior fragment was considered. Other fixation criteria such as postoperative step-off or instability after fixation of the lateral and medial malleoli are taken into account. In cases where fixation was needed, a percutaneous approach and an open posterolateral approach were equally preferred. CONCLUSIONS There is much variation in treatment of the posterior malleolar fracture amongst orthopaedic and trauma surgeons in the Netherlands. The percutaneous approach and open posterolateral approach to fixate the posterior malleolar fracture seem to be equally used in the Netherlands. Still, there is no uniformity in treatment of posterior malleolar fracture, especially for Bartonicek 2 and Bartonicek 3 fractures. Reoperation is considered by less than half of the surgeons in case of postoperative persistent step-off of more than 1 mm.

Abstract
INTRODUCTION An intra-articular impacted fragment (IAIF) could lead to articular incongruity and malreduction in ankle fractures with posterior malleolar fractures (PMFs). No studies have been conducted to determine whether the presence of IAIF affects the outcome of ankle fractures with PMF. The aim of our retrospective study was to evaluate the effect of IAIF on postoperative outcomes in PMF and analyze the relationship between area of IAIF and outcomes. MATERIALS AND METHODS We conducted a retrospective study of patients with a posterior malleolar fractures between June 2012 and January 2019 with a minimum follow-up of 2 years. Results of the Olerud-Molander ankle score (OMAS), EuroQol-5D (EQ-5D) index, EQ-5D visual analog scale (VAS), AOFAS (American orthopedic foot and ankle society ankle-hindfoot scale), visual analog scale (VAS) pain score and overall patient satisfaction scale were recorded. Outcomes of the PMF with IAIF group and PMF without IAIF group were compared. Sub-group analysis was given emphasis on the AIAIF > 40 mm2 group and AIAIF < 40 mm2 group in PMF with IAIF. RESULTS A total of 128 patients were included in the study, consisting of 86 patients with IAIF and 42 patients without IAIF. Regarding the osteoarthritis grade (> 1, ≤ 1), the differences werestatistically significant between the two groups (P = 0.044). The risk of articular malreduction was higher in the PMF with IAIF group than in the PMF without IAIF group (P = 0.035). Osteoarthritis grade (> 1, ≤ 1) was closely related to articular malreduction (P < 0.001). There were 51 patients in the AIAIF > 40 mm2 group and 35 patients in the AIAIF < 40 mm2 group of 86 patients in PMF with IAIF. There were statistically significant differences in trimalleolar fracture (P = 0.004), malreduction (P = 0.022), osteoarthritis grade (> 1, ≤ 1; P = 0.027), EQ-5D VAS score (P = 0.031), and AOFAS score (P = 0.047) between the subgroups. CONCLUSION The incidence of IAIF is associated with the area of the posterior malleolar fragment. Articular malreduction can lead to post-traumatic osteoarthritis, while IAIF is an important element for the quality of reduction, which is more likely to lead to articular malreduction. IAIF should be reduced if AIAIF is over 40 mm2. Otherwise, the patient will suffer a poor prognosis and post-traumatic osteoarthritis. Therefore, ankle fractures with PMF should undergo a CT scan preoperatively in order for providers to optimal treatment protocols. LEVEL OF EVIDENCE Level III.

Abstract
PURPOSE Fragility ankles fractures in the geriatric population are challenging to manage, due to fracture instability, soft tissue compromise, and patient co-morbidities. Traditional management options include open reduction internal fixation, or conservative treatment, both of which are fraught with high complication rates. We aimed to present functional outcomes of elderly patients with fragility ankle fractures treated with retrograde ankle fusion nails. METHODS A retrospective observational study was performed on patients who underwent intramedullary nailing with a tibiotalocalcaneal nail. Twenty patients met the inclusion criteria of being over sixty and having multiple co-morbidities. Patient demographics, AO/OTA fracture classification, intra-operative and post-operative complications, time to mobilisation and union, AOFAS and Olerud-Molander scores, and patient mobility were recorded. RESULTS There were seven males and thirteen females, with a mean age of 77.82 years old, five of whom are type 2 diabetics. Thirteen patients returned to their pre-operative mobility state, and the average Charlson Co-morbidity Index (CCI) was 5.05. Patients with a low CCI are more likely to return to pre-operative mobility status (p = 0.16; OR = 4.00). All patients achieved radiographical union, taking on average between 92.5 days and 144.6 days. The mean post-operative AOFAS and Olerud-Molander scores were 53.0 and 50.9, respectively. There were four cases of superficial infection, four cases of broken or loose distal locking screws. There were no deep infections, periprosthetic fractures, nail breakages, or non-unions. CONCLUSION Tibiotalocalcaneal nailing is an effective and safe option for managing unstable ankle fractures in the elderly. This technique leads to lower complication rates and earlier mobilisation than traditional fixation methods.

Abstract
PURPOSE Ankle fractures are commonly occurring fractures, especially in the aging population, where they often present as fragility fractures. The disease burden and economic costs to the patient and society are considerable. Choosing accurate outcome measures for the evaluation of the management of ankle fractures in clinical trials facilitates better decision-making. This systematic review assesses the evidence for the measurement properties of patient-reported outcome measures (PROMs) used in the evaluation of adult patients with ankle fractures. METHODS Searches were performed in CINAHL, EMBASE, Medline and Google Scholar from the date of inception to July 2021. Studies that assessed the measurement properties of a PROM in an adult ankle fracture population were included. The included studies were assessed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology for systematic reviews of PROMs. RESULTS In total, 13 different PROMs were identified in the 23 included articles. Only the Ankle Fracture Outcome of Rehabilitation Measure (A-FORM) presented some evidence on content validity. The Olerud-Molander Ankle Score (OMAS) and Self-reported Foot and Ankle Score (SEFAS) displayed good evidence of construct validity and internal consistency. The measurement properties of the OMAS, LEFS and SEFAS were most studied. CONCLUSION The absence of validation studies covering all measurement properties of PROMs used in the adult ankle fracture population precludes the recommendation of a specific PROM to be used in the evaluation of this population. Further research should focus on validation of the content validity of the instruments used in patients with ankle fractures.

Abstract
BACKGROUND The epidemiology and payer costs for ankle fractures are not well documented. This study evaluated: (1) the incidence of ankle fracture and ankle surgery following fracture in the US population; and (2) the clinical presentation of patients presenting with ankle fractures requiring surgery, their complication rates, and payer costs. METHODS Patients in the IBM® MarketScan® Commercial and Medicare Supplemental databases with an inpatient/outpatient diagnosis of ankle fracture from 2016 to 2019 were stratified by age group and gender, and rates of fracture per 10,000 enrollees were estimated. Surgically-treated patients between January 2016 - October 2021 were further analyzed. One-year post-surgical outcomes evaluated complication rates (e.g., infection, residual pain), reoperations, and 1-year payments. Standard descriptive statistics were calculated for all variables and outcomes. Generalized linear models were designed to estimate payments for surgical care and incremental payments associated with postoperative complications. RESULTS Fracture cases affected 0.14% of the population; 23.4% of fractures required surgery. Pediatric and elderly patients were at increased risk. From 3 weeks to 12 months following index ankle surgery, 5.5% (5.3% - 5.7%) of commercially insured and 5.9% (5.1% - 6.8%) of Medicare patients required a new surgery. Infection was observed in 4.4% (4.2% - 4.6%) commercially insured and 9.8% (8.8% - 10.9%) Medicare patients, and residual pain 3 months post-surgery was observed in 29.5% (28.7% - 30.3%) commercially-insured and 39.3% (36.0% - 42.6%) Medicare patients. Commercial payments for index surgery ranged from $9,821 (95% CI: $9,697 - $9,945) in the ambulatory surgical center to $28,169 (95% CI: $27,780 - $28,559) in the hospital inpatient setting, and from $16,775 (95% CI: $16,668 - $16,882) in patients with closed fractures, to $41,206 (95% CI: $38,795 - $43,617) in patients with Gustilo III fractures. Incremental commercial payments for pain and infection averaged $5,200 (95% CI: $4,261 - $6,139) and $27,510 (95% CI: $21,759 - $33,261), respectively. CONCLUSION Ankle fracture has a high incidence and complication rate. Residual pain affects more than one-third of all patients. Ankle fracture thus presents a significant societal impact in terms of patient outcomes and payer burden.

Influence of posterior malleolar fragment morphology on the outcomes of trimalleolar fractures: A systematic review and meta-analysis. Foot Ankle Surg 2022; 28:1337-1344.

Abstract
BACKGROUND Trimalleolar fractures are generally considered to have inferior outcomes among ankle injuries. Historically, emphasis was placed on the size of the posterior malleolar fracture (PMF) to guide surgical decision-making and predict outcomes. Recent studies have suggested that the morphology of the PMF fragment is more important than its size. The aim of this systematic review was to determine if the outcomes of trimalleolar fractures depend on the morphology of the PMF as per the Haraguchi classification system after surgical fixation. METHODS A systematic literature search was conducted in the electronic databases of PubMed, Embase, Scopus, and Ovid. Title and abstracts were screened, and data from eligible studies were extracted. Meta-regression and pooled analysis was performed using appropriate computer software. RESULTS 11 studies with 597 patients were included in the final analysis. Pooled mean AOFAS score was 87.43 (95% CI 84.24-90.62) after a mean follow-up of 31.6 months. Univariate and multivariate meta-regression analysis demonstrated that as the percentage of Haraguchi type 1 patients increased, there was a statistically significant improvement in outcome scores. A similar trend was noted for Haraguchi type 3 fractures, and a reverse trend was observed for Haraguchi type 2 injuries, although neither were statistically significant. CONCLUSION Our review suggests that the outcomes of trimalleolar fractures after surgical fixation may depend on the morphology of the PMF, with Haraguchi type 1 fractures having overall superior functional outcomes than Haraguchi type 2 and 3 injuries. Future studies need to done to conclusively prove or refute these findings.

Abstract
OBJECTIVE Ankle fractures are often combined with syndesmotic instability, requiring reduction and stabilization. However, the optimal level for syndesmotic screw positioning remains unclear. This study aims to evaluate the effect of different syndesmotic screw insertion levels on postoperative clinical outcomes and determine whether an optimal level exists. METHODS This retrospective study included data from 43 adult patients with acute closed ankle fractures combined with intraoperative evidence of unstable syndesmotic injuries who underwent open reduction internal fixation from January 1, 2017 to March 1, 2018 according to the inclusion and exclusion criteria. All 43 patients were divided into three groups based on the syndesmotic screw placement level: trans-syndesmotic group: screw level of 2-3 cm; inferior-syndesmotic group: screw level <2 cm; and supra-syndesmotic group: screw level >3 cm. Clinical outcomes were measured at the final follow-up, including the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Olerud-Molander Ankle Score (OMAS), short-form 36-item questionnaire (SF-36), visual analogue scale (VAS) score and restrictions in ankle range of motion (ROM). The relationships between screw placement level and clinical outcomes were analyzed with the Kruskal-Wallis H-test and Spearman correlation analysis. RESULTS The median follow-up duration was 15 months (range, 10-22 months). No patients developed fracture nonunion or malunion or experienced hardware failure. The outcome scoring systems showed an overall score for the entire group of 94.91 points for the AOFAS ankle-hindfoot score, 83.14 for the OMAS, 96.65 for the SF-36, 1.77 for the VAS, 9.14° for the restrictions in dorsiflexion, and 1.30° for the restrictions in plantarflexion. There were no significant differences among three groups in clinical outcomes (P > 0.05). Neither the AOFAS score nor OMAS had significant correlations with screw insertion level (P = 0.825 and P = 0.585, respectively). No postoperative arthritis or widening of the tibiofibular space was observed at the final follow-up. CONCLUSION Different syndesmotic screw placement levels appear not to affect the clinical outcomes of ankle fractures with syndesmotic instability. No optimal level was observed in this study. Our findings suggest other clinically acceptable options apart from syndesmotic screw placement 2-3 cm above the ankle.

Abstract
INTRODUCTION To date, there has been no prospective randomized trial supporting the rationale of the use of headless compression screw (HCS) compared to conventional fixation methods for medial malleolar fractures. This study aimed to prospectively compare the outcomes of the HCS and tension band wire (TBW) for the fixation of medial malleolar fractures. MATERIAL AND METHODS Sixty patients were randomized to receive either an HCS or a TBW for the fixation of a medial malleolar fracture. Clinical outcomes were assessed using the Olerud-Molander ankle score (OMAS), EuroQoL five-dimensional instrument (EQ-5D) score, visual analog scale (VAS) score, patient satisfaction with implant-related symptoms, operative time, and incision length. Radiographic outcomes were assessed using the presence of nonunion, delayed union, and articular incongruity. Clinical and radiographic assessments were performed at 2 and 6 weeks and 3, 6, and 12 months postoperatively. RESULTS The OMAS, EQ-5D score, VAS score, and operative time did not differ between the HCS and TBW groups; however, the HCS group had greater satisfaction with implant-related symptoms and smaller incision than the TBW group. There was no difference in the presence of nonunion, delayed union, and articular incongruity. CONCLUSION HCS fixation for medial malleolar fractures is not inferior to TBW fixation, while reducing implant-related symptoms. These findings suggest that HCS is a viable alternative for the fixation of medial malleolar fractures.

BACKGROUND Fractures of the distal tibia involving the physis are relatively common in children. The data reported on long-term complication rates vary between studies. HYPOTHESIS Pediatric distal tibial fractures cause medium- and long-term growth disturbances. MATERIALS AND METHODS This was a retrospective single-center study. We included physeal distal tibial fractures that were treated in the operating room with a minimum 12-month follow-up. The analysis included age, gender, weight status, circumstances and energy of the injury, fracture type, subsequent treatment, complications, duration of follow-up, radiologic findings and functional outcomes using the AOFAS. RESULTS A total of 46 patients were included with a mean age of 12.8 years (2.4-15.9 years) and a mean follow-up of 35.8 months (12-119). At the longest follow-up, 7 patients (15.2%) had growth disturbances. The mean AOFAS score was 95/100 and a decreased ankle range of motion was observed in 18 patients, but it was always less than 10°. High-energy injuries (20 patients) resulted in worse clinical outcomes and a significantly higher rate of growth disturbances (p=.03). DISCUSSION This study confirmed the presence of growth disturbances following pediatric distal tibial fractures, especially in cases of high-energy trauma. Therefore, these fractures should be monitored until the end of the growth period. LEVEL OF EVIDENCE IV; retrospective study.

The role of the posterior malleolus in the treatment of unstable upper ankle joint injuries - A biomechanical study. Foot Ankle Surg 2022; 28:979-985. [PMID: 35177329 DOI: 10.1016/j.fas.2022.02.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Revised: 01/28/2022] [Accepted: 02/09/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND This biomechanical study aimed to test if the fixation of the posterior malleolus (PM) only with screws inserted from posterior to anterior (PA) restores stability comparable with the natural condition. The extent of stability was also compared with that of anterior to posterior (AP) screw osteosynthesis (OS) with an additional syndesmotic screw (SS). METHODS First, the stability of the upper ankle joint in seven pairs of intact lower legs were examined. Subsequently, half of the lower legs were treated with PA screw fixation of a PM fracture without SS and the other half with AP screw fixation with additional tricortical SS. RESULTS PA OS without SS showed significantly more diastasis (p = 0.027). The AP OS with an SS revealed a diastasis that was comparable with the intact condition (p = 0.797). The use of SS led to significantly higher stability compared to OS without SS (p = 0.019). CONCLUSIONS The Fixation of the PM alone without an additional syndesmotic screw cannot achieve intact upper ankle stability. Fixation of a PM fracture with an SS helps in nearly achieving the natural condition.

Sharma T, Farrugia P. Early versus late weight bearing & ankle mobilization in the postoperative management of ankle fractures: A systematic review and meta-analysis of randomized controlled trials. Foot Ankle Surg 2022; 28:827-835. [PMID: 35337752 DOI: 10.1016/j.fas.2022.03.003] [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: 11/12/2021] [Revised: 02/11/2022] [Accepted: 03/01/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND While open reduction and internal fixation is currently considered the optimum treatment option for displaced ankle fractures, the most optimal post-operative rehabilitation strategy in this setting remains unclear. The objective of this investigation was to compare the effect of early vs. late weight bearing and ankle mobilization in the post-operative management of ankle fractures. METHODS Medline, Embase, CENTRAL, Scopus, CINHAL, and Web of Science were searched to identify randomized controlled trials (RCTs) and quasi-RCTs. Two review authors screened articles, abstracted data, and evaluated risk of bias in duplicate. Outcomes of interest included post-operative ankle function and overall time to return to work. Studies on weight bearing and ankle mobilization were analysed separately and all data were pooled using random-effects models. RESULTS Eighteen trials were included in the review of which 14 were included in the meta-analysis of at least one outcome of interest. Majority of the studies presented a high overall risk of bias. Early weight bearing demonstrated significantly better short-term postoperative functional scores at 6-9 weeks postoperatively (SMD: 0.39, 95% CI: 0.19, 0.58; p < 0.0001; I2 = 0%). However, the functional effect of early weight bearing compared to late weight bearing gradually became equivalent by the 6 month postoperative time-period. Early weight bearing also demonstrated a significant reduction in the time to return to work/daily activities (MD: -12.29, 95% CI: -17.39, -7.19; p < 0.0001; I2 = 0%). In comparison, no significant differences were found between early ankle mobilization/exercises and immobilization. CONCLUSION Our findings suggest a potential role of EWB in improving post-operative ankle-function in the short-term and reducing the overall time to return to work/daily activities, but no clinical benefit associated with early ankle mobilization post-surgery.

Abstract
Background Ankle traumas are common presenting injuries to emergency departments in Australia and worldwide. The Ottawa Ankle Rules (OAR) are a clinical decision tool to exclude ankle fractures, thereby precluding the need for radiographic imaging in patients with acute ankle injury. Previous studies support the OAR as an accurate means of excluding ankle and midfoot fractures, but have included a paediatric population, report both the ankle and mid-foot, or are greater than 5 years old. This systematic review and meta-analysis aimed to update and assess the existing evidence of the diagnostic accuracy of the Ottawa Ankle Rule (OAR) acute ankle injuries in adults. Methods A systematic search and screen of was performed for relevant articles dated 1992 to 2020. Prospective and retrospective studies documenting OAR outcomes by physicians to assess ankle injuries were included. Critical appraisal of included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool. Outcomes related to psychometric data were pooled using random effects or fixed effects modelling to calculate diagnostic performance of the OAR. Between-study heterogeneity was assessed using the Higgins I2 test, with Spearman’s correlation test for threshold effect. Results From 254 unique studies identified in the screening process, 15 were included, involving 8560 patients from 13 countries. Sensitivity, specificity, negative likelihood ratio, positive likelihood ratio and diagnostic odds ratio were 0.91 (95% CI, 0.89 to 0.92), 0.25 (95% CI, 0.24 to 0.26), 1.47 (95% CI, 1.11 to 1.93), 0.15 (95% CI, 0.72 to 0.29) and 10.95 (95% CI, 5.14 to 23.35) respectively, with high between-study heterogeneity observed (sensitivity: I2 = 94.3%, p < 0.01; specificity: I2 = 99.2%, p < 0.01). Most studies presented with low risk of bias and concern regarding applicability following assessment against QUADAS-2 criteria. Conclusions Application of the OAR is highly sensitive and can correctly predict the likelihood of ankle fractures when present, however, lower specificity rates increase the likelihood of false positives. Overall, the use of the OAR tool is supported as a cost-effective method of reducing unnecessary radiographic referral, that should improve efficiency, lower medical costs and reduce waiting times.

The use of intraoperative comparative fluoroscopy allows for assessing sagittal reduction and predicting syndesmosis reduction in ankle fractures. Foot Ankle Surg 2022; 28:750-755. [PMID: 34686414 DOI: 10.1016/j.fas.2021.10.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2021] [Revised: 08/24/2021] [Accepted: 10/04/2021] [Indexed: 02/04/2023]
Abstract
UNLABELLED Intraoperative fluoroscopic parameters have shown to be poor predictors for ankle syndesmosis reduction, with up to 52% of syndesmotic malreduction (SMR) reported in the literature. Anteroposterior Tibio-Fibular index (APTF) was previously described to evaluate sagittal tibiofibular alignment in lateral ankle radiographs with a high correlation between both ankles in uninjured subjects. Reproducible intraoperative measurements for sagittal syndesmotic reduction are lacking. We propose the use of the "cAPTF," calculated as the absolute difference between the APTF of the non-injured and the operated ankle, to evaluate sagittal syndesmotic reduction. OBJECTIVE Determine the predictive capability of cAPTF for SMR. METHOD Prospective observational study. INCLUSION CRITERIA patients with unstable ankle fractures requiring syndesmotic fixation, with a healthy contralateral ankle. Intraoperatively APTF was measured in both ankles after syndesmotic fixation. Postoperatively cAPTF was calculated. Only direct syndesmosis visualization through the lateral approach and AP and mortise views were used by surgeons to assess syndesmotic reduction. Quality of syndesmotic reduction was evaluated with bilateral postoperative CT. To estimate cAPTF discriminatory power for SMR, a receiver operative characteristic (ROC) curve was obtained and the area under the ROC curve was calculated. Youden index was used to determine the ideal cAPTF cut-off value for predicting SMR. For this determined cut-off value, sensitivity, specificity, and likelihood ratio were calculated. RESULTS Fifty-two patients were included. Sixteen (30%) had SMR. Patients with SMR had a statistically significant higher cAPTF value than the well reduced (median 0.26 vs 0.09; P < 0.01). The cAPTF cut-off value to predict SMR was 0.161. A cAPTF greater than 0.161 had 100% sensitivity and 97,2% specificity for SMR. The area under the ROC curve was 0.99. CONCLUSION Intraoperative cAPTF has excellent discriminatory power for predicting syndesmotic malreduction. We propose the routine use of intraoperative bilateral comparative fluoroscopy to assess sagittal syndesmotic reduction.

Abstract
INTRODUCTION Ankle fractures are amongst the most common open fracture injuries presenting to major trauma centres (MTC) and their management remains a topic of debate. Incidence is increasing particularly in the elderly population however the optimal surgical approach and risk factors for unplanned reoperation remain scarce. We therefore conducted a retrospective case study to analyse our institution's outcomes as well as identify risk factors for early unplanned reoperation. MATERIALS AND METHODS Sixty-five consecutive open ankle fractures were identified using our institutional database between July 2016 and July 2020. Medical records and operation notes were reviewed to identify patient age at injury, Sex, co-morbidities and other co-morbidities, fracture configuration, extent of soft tissue injury, fixation type and post-operative complications. The data was categorised into four groups for analysis, 1) age, 2) AO-OTA classification 3) Sex 4) Gustilo-Anderson grade. Statistical analysis was undertaken to identify predictors of unplanned reoperation. RESULTS The mean age of patients at the time of injury was 60.8. Unplanned reoperation rate was 17.5%. Age and Gustilo-Anderson classification grade were both statistically significant predictors of unplanned reoperation. AO-OTA classification, Sex and Diabetes were not statistically significant factors associated with unplanned reoperation. CONCLUSION Age and quality of soft tissue envelope are significant risk factors for unplanned reoperation. Patients with these risk factors may benefit from an alternative surgical approach.

Quantifying balance deficit in people with ankle fracture six months after surgical intervention through the Y-Balance test. Gait Posture 2022; 95:249-255. [PMID: 33243522 DOI: 10.1016/j.gaitpost.2020.10.037] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Revised: 10/28/2020] [Accepted: 10/30/2020] [Indexed: 02/02/2023]
Abstract
BACKGROUND Ankle fractures are among the most common traumatic fractures and have a great socio-economic impact. Consequences of an ankle fracture requiring surgical treatment (e.g. pain, reduced ankle range of motion (ROM), muscle weakness, etc.) lead to balance deterioration, which has a profound impact on activities of daily living. However, to the best of the authors' knowledge, no reliable clinical tests are available to monitor balance in patients after ankle surgery. OBJECTIVES To quantify single-leg dynamic balance in patients with bimalleolar ankle fracture through the Y-Balance test (YBT). The second objective was to analyze the impact of ankle dorsiflexion ROM and hip strength on balance to optimize balance rehabilitation programs. DESIGN Cross-sectional study. METHODS 22 participants, who had undergone surgery after bimalleolar ankle fractures, were assessed for ankle ROM, hip strength, and dynamic balance six-months after the surgical intervention. The within-session reliability of YBT was calculated through the intraclass correlation coefficient (ICC) and the standard error of measurement (SEM). Student's t-tests were used to assess leg differences. A multiple regression analysis was performed to evaluate the role of ankle dorsiflexion ROM and hip abductor and adductor strength in predicting balance performance. RESULTS YBT showed high-to-excellent within-session relative reliability (Healthy leg: 0.85 ≤ ICC≤0.96; Operated leg: 0.84 ≤ ICC≤0.96). SEM values were below 3.3 %. The operated leg showed significant lower YBT scores for anterior reach direction (-9.0 %; g=-0.70) and composite score (-4.5 %; g=-0.34). Multiple regression analysis showed that both, ankle dorsiflexion and hip abductor and adductor strength explained 66 % of the variance in the YBT anterior direction of the operated leg. CONCLUSIONS The YBT is a reliable tool that allows the quantification of single-leg dynamic balance impairments from 6-months after surgery in patients with bimalleolar ankle fracture. Between-leg YBT differences in the anterior direction can be used as reference scores (3.3 %) for balance restoration. Balance rehabilitation programs should focus on improving ankle functionality and reducing hip muscle weakness with specific hip strength exercises and balance exercises with similar demands to the reaching tasks of the YBT to promote a faster recovery.

Abstract
Purpose To compare the clinical results, complication rates, and radiographic outcome between both methods of fixation of lateral malleolar fractures: lateral neutralization plates and intramedullary fully threaded screws. Patients and methods This prospective case series study involved 73 patients with fractured lateral malleolus of type A, B according to Weber classification, to whom internal fixation was performed by either lateral plate and screws construct (Group A) or intramedullary screw (Group B). All patients were followed up for 12 months at least, with an average follow-up time of 12.7 months. Results There was no significant difference in the functional outcome score between both groups. The intramedullary screw group had a significantly shorter operative time and time to full union (P<0.001 and =0.006 respectively). There was a relatively higher accuracy of reduction with the plate fixation group, but it was statistically insignificant. There was a relatively fewer complication rate with the use of intramedullary screw fixation compared to plate fixation. Conclusion The use of intramedullary fixation is a good alternative for plate fixation in low fibular fractures (Weber A and B). Although plate fixation provides an optimal anatomic reconstruction of the fractures, intramedullary fixation may have a lower risk of complications.

Surgical treatment of displaced isolated lateral malleolar fractures: incidence of adverse events requiring revision: a retrospective cohort study. J Orthop Surg Res 2022; 17:252.

Abstract
Background Recent systematic reviews support that non-operative management should be the standard treatment for all stable isolated lateral malleolar fractures (ILMFs), regardless of fibular fracture displacement. Surgical fixation of ILMFs carries a risk of adverse events (AEs), and many patients will later require implant removal. We wanted to estimate the incidence of AEs requiring revision after surgical fixation of “potentially stable” displaced ILMFs before non-operative treatment became standard care in our department. Materials and methods To identify patients with “potentially stable” ILMFs who had been treated surgically in a historical cohort, we retrospectively applied the stability-based classification system, introduced by Michelson et al., to a cohort of 1006 patients with ankle fractures treated surgically from 2011 to 2016. The primary outcome of this retrospective cohort study was the incidence of AEs that had functionally significant adverse effects on outcome and required revision in the first 12 months after surgery. AEs were graded and categorized using the Orthopedic Surgical Adverse Events Severity (OrthoSAVES) System. Results The study population comprised 108 patients with “potentially stable” displaced ILMFs; 4 patients (3.7% [95% CI (0.1–7.3%]) experienced AEs requiring revision in the first twelve months after surgery. There were 5 additional patients (4.6%) with functionally significant AEs where revision surgery was not indicated within the first twelve months after surgical fixation. A further 5 patients (4.6%) had AEs managed in the outpatient clinic (grade II); 36 patients (33.3%) required secondary implant removal due to implant-related discomfort. Conclusions Surgical fixation of ILMFs carries a risk of severe AEs, and many patients will subsequently need implant-removal procedures. Further prospective studies are required to ascertain whether non-operative treatment can lower the risk of AEs and the need for additional surgical procedures.

Abstract
BACKGROUND Lauge-Hansen supination external rotation (SER)-type ankle fractures are very common and account for up to 75% of all ankle fractures. Assessing deltoid integrity is key for surgical decision making. Ultrasound has been used recently to assess the integrity of the deltoid ligament and differentiate between SER II and SER IV fractures. The aim of this article is to review the literature for studies assessing the diagnostic accuracy of ultrasound in this group of patients. METHODS After registering the protocol with PROSPERO, Embase, Ovid MEDLINE, Web of Science Core Collection, and Google Scholar were systematically searched. Studies that satisfied the following inclusion criteria were assessed: (1) Adult patients (>16 years), (2) Acute SER-type ankle fractures assessed within 2 weeks of the injury, (3) Diagnostic accuracy studies. Risk of bias assessment was conducted and a narrative synthesis of the results presented. RESULTS A total of five studies satisfied our inclusion criteria and were included for review. These had a total of 175 patients studied. All studies showed a sensitivity of 100% and specificity of 90-100% for detecting a complete tear of the deltoid. All papers had a significant risk of bias inherent to the design. Only patients undergoing surgery were exposed to the gold standard of operative intervention. CONCLUSION Ultrasound scan has shown excellent diagnostic accuracy for detecting complete deltoid ruptures in SER ankle fractures. These results however should be interpreted with caution. Perhaps a different approach is needed to assess the efficacy of ultrasound scans in patient with SER type fractures.

Abstract
PURPOSE Functional outcome in trimalleolar fractures is largely correlated to the reduction of the posterior fragment. Until recently, fixation was mainly performed for large fragments, by percutaneous anterior to posterior ('A to P') screw placement after closed reduction. Nowadays, ORIF via a posterolateral approach seems to gain in popularity. The aim of this study was to compare the postoperative photographs of operated trimalleolar fractures after either fracture treatment method, for fracture diastasis and step-off. MATERIAL AND METHODS All consecutive patients with trimalleolar fractures, including posterior fragments of >5% of the articular surface and operated between 2007-2013 were analysed on size of posterior fragment, post-operative gap and step-off by three observers. The patients were divided into three groups; A to P screw fixation, ORIF via the posterolateral approach and no posterior fragment fixation at all. RESULTS 180 patients with trimalleolar ankle fractures were included for analyses. Twenty five posterior fragments were fixated percutaneously from anterior to posterior (group 1) and 51 underwent open reduction and internal fixation through a posterolateral approach (group 2). 104 patients underwent no posterior malleolus fixation (group 3). The average size of posterior fragment was 34% in group 1, 27% in group 2 and 16% in group 3. A postoperative step-off >1 mm was found in 40% (group 1), 9% (group 2) or 34% respectively (group 3). CONCLUSIONS Fixation of the posterior malleolus through an open posterolateral approach leads to better radiological results as compared to percutaneous 'A to P' screw fixation or no fixation at all.

Abstract
Background: Trauma and subsequent immobilization of the lower limb increase the risk of venous thromboembolism (VTE). Our aim was to evaluate compliance with national guidance on operatively managed ankle fractures and VTE chemoprophylaxis before and after implementation of a change in practice. Methods: We conducted an initial single-center audit of patients undergoing ankle fracture fixation. The primary outcome was quality of operation note documentation, and the secondary outcome was whether VTE chemoprophylaxis was prescribed on discharge. All stakeholders were educated on audit findings, new guidelines were synthesized, and the practice was re-audited. Results: A total of 137 patients were included in the initial audit, and 49 patients were included in the loop closure. The first audit highlighted that chemoprophylaxis prescription on discharge was significantly higher when both the agent and treatment duration were clearly stipulated in the operation note compared to when either treatment duration or both agent and treatment duration were omitted (97.2% vs 51.8% and 32.4%, respectively, P<0.001). Following our intervention, operation note documentation of agent and treatment duration improved from 29% to 90% (P<0.001). VTE chemoprophylaxis on discharge significantly improved from 57% to 98% (P<0.001). Conclusion: Our closed-loop audit identified suboptimal operation note documentation as the root cause of VTE noncompliance. The operation note is an important clinical interface between the operating theater and ward staff. We addressed these deficiencies with a basic intervention.
