Objective: This study evaluated the reproducibility of the Lauge-Hansen classification among orthopedic residents and more experienced orthopedists. Methods: The inclusion criteria were ankle fractures with adequate radiographs taken in anteroposterior (AP), true AP and P (profile) views, which were individually analyzed by physicians. The analysis was performed based on the Lauge-Hansen classification. The raters were 5 orthopedic professionals from our department: 3 residents and 2 board-certified orthopedists (one with less than 10 years of experience, and the other with more 10 years of experience in the field). The professionals first analyzed and classified 30 ankle fracture radiographs; then, after 1 week, they were asked to perform a new evaluation. The radiographs were shown without names or other identifying information. The classifications were subsequently examined based on the analysis of the supporting material that had been previously provided for each individual. A consensus decision regarding the classification was made among all professionals at the end of the study. Results: The professionals were asked to analyze radiographs from 30 patients with ankle fracture, among whom supination-external rotation was the most common diagnosis. The results were outlined in tables and plotted in graphs; in a second evaluation performed after 1 week, there were 66% hits and 34% errors, whereas the percentage of hits in the first evaluation was 61.33%. Conclusion: The routine use of management classifications by physicians facilitates the understanding of these classifications by other professionals in the field while increasing interobserver agreement.

Background: The utility of computed tomography (CT) for measuring medial clear space (MCS) for determination of the stability of supination external rotation (SER) ankle fractures and in comparison to standard radiographs is unknown. We compared MCS on gravity stress (GS) radiographs to GS and weight bearing (WB) cone-beam CT (CBCT). Methods: An AO SER 44B3.1 ankle fracture was simulated in 10 human cadavers, also serving as controls. MCS was measured on GS radiographs, GS CBCT, and a simulated WB CBCT scan. Specimens were stable if MCS was <5 mm and unstable if MCS was ≥5 mm. Paired t tests were used to compare MCS from each imaging modality for controls versus SER injuries and stable versus unstable specimens. Results: Compared with controls assessed by GS radiographs, MCS was greater for an SER injury when assessed by GS radiograph and GS CBCT scan within the stable group. Compared with controls assessed by GS radiographs, MCS was greater for SER injuries when assessed by GS radiograph, GS CBCT scan, and WB CBCT within the unstable group. MCS was reduced for stable versus unstable SER injuries assessed by WB CBCT. Conclusion: In a cadaveric model of SER ankle fracture, the medial clear space was statistically significantly greater for the experimental condition when assessed by gravity stress radiograph and gravity stress CBCT scan. Under weight-bearing conditions, the cone-beam CT scanner distinguished between stable and unstable ankles in the experimental condition. Clinical Relevance: This study suggests that a WB cone-beam CT scan may be able to distinguish between stable and unstable SER ankle fractures and influence operative decision making.

ABSTRACT Objective: To evaluate the frequency of deltoid ligament injury in bimalleolar supination-external rotation type fractures and whether there is a correlation between the size of the fractured medial malleolus and deltoid ligament injury . Methods: Twenty six consecutive patients underwent magnetic resonance exams after clinical and radiographic diagnosis of bimalleolar supination-external rotation type ankle fractures . Results: Thirteen patients (50%) presented deltoid ligament injury associated to bimalleolar ankle fracture. Partial injury was present in seven (26.9%) patients and total injury in six (23.1%). Regarding medial fragment size, the average was 2.88 cm in the absence of deltoid ligament injury. Partial injuries presented 1.93 cm and total 2.1 cm on average . Conclusion: Deltoid ligament injury was present in 50% of bimalleolar ankle fractures. Smaller medial malleolus fragments, especially concerning the anterior colliculus, presented greater association with partial deltoid ligament injuries. Level of Evidence IV, Cross Sectional Study.

Background: Despite appropriate care, a subset of patients with ankle fractures has persistent pain. This condition may be associated with intra-articular pathology, which is present up to 65% of the time. Purpose: To quantify how much of the talus is visible through an open approach to a standard supination external rotation bimalleolar ankle fracture as a percentage of the entire weightbearing surface of the talus. Study Design: Descriptive laboratory study. Methods: Standard ankle approaches to lateral and medial malleolar fractures were performed in 4 cadaveric ankles from 2 cadavers. Osteotomies were made to simulate a supination external rotation bimalleolar ankle fracture based on the Lauge-Hansen classification. The visible segments of talar cartilage were removed. The tali were then exhumed, and the entire weightbearing superior portion of the talus was assessed and compared with the amount of cartilage removed by an open approach. The mean of the data points as well as the 95% confidence interval were calculated. Results: Four ankle specimens from 2 cadavers were used for these measurements. The mean surface area of the talus was 14.0 cm2 (95% CI, 13.3-14.7 cm2), while the mean area visible via an open approach was 2.1 cm2 (95% CI, 0.5-3.6 cm2). The mean proportion of the talus visualized via an open approach was 14.8% (95% CI, 3.6-26.1%). Conclusion: These findings indicate that the true area of weightbearing talar surface visible during an open exposure may be less than what many surgeons postulate. Clinical Relevance: Only a small fracture of the talus is visible via an open approach to the talus during fracture fixation. This could warrant arthroscopic evaluation of these injuries to evaluate and treat osteocondral lesions resulting from ankle fractures.

Background: While open reduction of displaced ankle fractures generally is accepted as the standard of care, relatively little is known about the health related quality of life after treatment. It is generally accepted that clinical results of treatment for supination-external rotation stage IV ankle fractures are favorable. The goal of this investigation was to determine the relationship between clinical results and health-related quality of life outcome measures in a consecutive series of patients treated for closed supination-external rotation stage IV ankle fractures. Methods: Twenty-six of 156 patients who had operative treatment for closed, displaced supination-external rotation stage IV ankle fractures during a 9-year period, completed the Short Musculoskeletal Function Assessment (SMFA) outcome questionnaire. Radiographs and clinical records were reviewed to determine quality of operative repair, postoperative morbidity, and the development of post-traumatic arthritis. Results: There were no postoperative complications. Of the 26 patients who returned the SMFA questionnaires, 19 had “good,” and seven had “fair” reduction of their fractures. Six showed radiographic evidence of arthritis at followup. Study participants reported scores that were similar to the general population in five of the six domains of the SMFA. Their scores in the mobility index were statistically less favorable (23.72 vs. 13.61, p = 0.016) when compared to the general population. Participants with “good” operative reductions and no evidence of arthritis at followup showed no significant difference to the general population. Participants with either a “fair” operative reduction or evidence of postoperative arthritis at followup had less favorable scores in the daily activities (mean 13.45 vs. 11.82, p = 0.004), mobility (43.43 vs. 13.61, p = 0.001), dysfunction (32.89 vs. 12.70, p = 0.014), and bother (35.80 vs. 13.77, p = 0.020) domains, when compared to the general population. Conclusions: The results of this investigation suggest that patients with excellent radiographic operative reductions and no arthritis as early as 6 months after surgery sustain no lasting unfavorable effect on health related quality of life. Patients with “fair” radiographic reduction, or presence of arthritis or both at followup, are likely to have a negative effect on their quality of life.

Category: Trauma Introduction/Purpose: Differentiating stable isolated fibula fractures consistent with supination external rotation (SER) II ankle fractures from unstable SER IV fractures is essential in determining the need for surgical stabilisation. Stress radiographs are usually required to assess stability including gravity stress views (GSV) and external rotation views (ER). There is no clear consensus as to which modality is most useful to determine stability in a fracture clinic or emergency setting. In last, few years clinical uncertainty about the reliability has led researcher to focus on weight bearing radiographs (WB) .We aim to review recent literature regarding reliability of WB radiographs to estimate the stability of supination external rotation ankle fractures. Methods: A systematic review of the literature relating to radiological assessment of stability of supination external rotation ankle fractures was conducted according to PRISMA guidelines. The systematic review was prospectively registered with PROSPERO. It involved the following steps: Researching the question-Do weight bearing radiographs estimate the stability of an isolated distal fibula fracture? Setting inclusion and exclusion criteria-All English language articles published in the including any Randomised controlled trials (RCT’s) and cohort studies. Data collection)– A literature search of Medline (PubMed), the Cochrane Bone, Joint, and Muscle Trauma Group trial register, the Cochrane central register of controlled trials, Embase and CINAHL was undertaken. The grey literature was searched. Key terms ‘supination external rotation fracture’, ‘stability’. Other variations to the key words were ‘weight bearing’, “axial load”, ‘stress x-rays’, ‘systematic reviews’ and ‘meta-analysis’. Results: A total of six studies met the inclusion criteria including 601 patients. No previous systematic review on stress radiographs including weight bearing was published. All studies concluded weight bearing radiographs is an easy, pain-free, safe and reliable method to estimate stability of isolated distal fibula fractures. No serious concerns or complications were reported. Conclusion: The evidence base contained many methodological limitations and most of the evidence was either level III or IV, and so any conclusion drawn from the research must be done so with caution. The studies suggest that GSV overestimates the instability which should be assessed with studies should focus on randomized controlled trials with narrow range of clinically useful outcome measures.
