Abstract
Background. The most common method of surgical stabilization of fibular fractures is plate osteosynthesis. Despite its ubiquity, there is a dearth of large series reporting implant-related outcomes and complications. The purpose of this study was to report on short-term complications and hardware removal after plate fixation of distal fibula fractures. Methods. A retrospective chart analysis and review of radiographic images was performed of 461 ankle fractures between 2011 and 2017. In 404 cases, a fibular fracture was treated surgically; 94.1% underwent tubular and 5.9% locking plate fixation. The primary outcome was radiographic union, with a mean follow-up of 11.6 months. Minor, intermediate, and major complications were recorded as well as the rate of hardware removal. Results. The union-rate with plate fixation was 99.5% (402/404). The overall complication rate was 19.3% (n = 78/404). Of these complications, 79.5% (62/78) were considered minor. These complications included erythema, heterotopic ossification, neurapraxia, delayed union, and deep-vein thrombosis; 20.5% (16/78) of the complications were considered intermediate (9/78, 11.5%) or major (7/78, 9.0%). Intermediate and major complications included deep infection, nonunion/malunion, and osteomyelitis. Subsequent surgery was needed in 7 cases (1.7%, 7/404). In another 93 patients, hardware-related symptoms were identified: 23 (5.7%) underwent syndesmosis screw removal and 54 (13.4%) hardware removal. No correlation to the fixation technique was identified. Conclusion. This study shows a relatively low rate of major complications and a high union rate of 99.5% for fibular plate osteosynthesis in a large cohort. Any other treatment, including other fixation techniques, will need to show an equivalent or better complication and reoperation profile.
