BACKGROUND: Syndesmosis fixation of Lauge-Hansen SER IV, Weber B @entity1171 is controversial. This study compared a matched pair of SER IV @entity1 with stress proven syndesmotic injuries with the same number without stress proven @entity3681 in terms of functional, @entity158 , and radiologic result. METHODS: The study was based on a RCT-study comparing syndesmotic transfixation to no fixation in SER IV (Weber B)-type @entity1171 . Twenty-four @entity1 with a @entity130 found on the intraoperative 7.5 Nm standardized external rotation test were compared to 24 @entity1 with a stable syndesmosis. The pairs were matched by @entity174 morphology, sex, and age. The primary outcome measure was ankle function as assessed by the Olerud-Molander score. Weight-bearing plain radiographs and 3T MRI of the injured ankle were used to assess ankle joint congruity and @entity571 , according to Kellgren-Lawrence classification and cartilage defects. RESULTS: The Olerud-Molander score was 86 in @entity130 @entity1 and 90 in @entity1 with normal syndesmosis (P = .28). The incidence of @entity3681 on plain radiographs was not significantly different between the groups (Grade I 5% vs 21%; Grade II 86% vs 75%; Grade III 9% vs 4%; P = .34). MRI scans showed @entity1844 in 54% of the @entity1 : 12 (56%) in the @entity130 group vs 13 (54%) in the group without @entity130 (P > .9). CONCLUSION: After 4 to 6 years of follow-up, clinical and radiologic outcome were not different in @entity1 with @entity130 compared to @entity1 with stable syndesmosis in SER IV (Weber B)-type @entity1171 . LEVEL OF EVIDENCE: Prognostic Level II, comparative study.
