The clinical outcome of fixation of posterior malleolus fragment in trimalleolar ankle fracture

Background Trimalleolar ankle fractures are complex injuries that often require surgery. Posterior malleolus fixation is important to restore ankle stability and function. The aim of this study was to evaluate the clinical outcomes associated with posterior malleolus fixation in patients with ankle fractures in the malleolus ankle fracture.

Methods From 2018 to 2024, clinical outcomes were assessed using the American Orthopedic Foot and Ankle Society (AOFAS) score, range of motion measurements, and radiographic evaluations. Complications and functional recovery were carefully recorded to analyze the effectiveness of posterior malleolus fixation in trimalleolus ankle fractures.

Results All 100 patients were included in the study. The mean AOFAS score at final follow-up was 85, indicating a significant improvement compared with the preoperative score. Radiographic analysis showed satisfactory alignment and integration of the posterior malleolus fragments in 92% of cases. Complications included minor infections and delayed wound healing in a few cases; however, overall, most patients achieved good results, demonstrating improved ankle stability and functional recovery.

Conclusions Posterior malleolus fixation in trimalleolar ankle fractures is associated with satisfactory clinical outcomes, increased stability and recovery from work. These findings support the importance of managing the malleolus during surgery for trimalleolus fractures. Further prospective studies are needed to validate these results and improve surgical techniques.
