Lateral malleolar region defects with exposed implants: proximally based peroneus brevis muscle flap

OBJECTIVE: Reconstruction of lateral malleolar region defects with exposed implants is a problematic situation for the reconstructive surgeon because there are limited options. The objective of our study was to revise the management of these defects and point out the role of proximally based peroneus brevis muscle flap. METHOD: Patients with an implant exposed tissue defects of the lateral malleolar region were evaluated retrospectively. All defects reconstructed with proximally based peroneus brevis muscle flap were included in this study. RESULTS: Of the 17 patients identified the mean age was 37.1 years (range 16-58 years). The size of the defects were 2-9cm in length (mean: 4.9cm) and 2-4cm in width (mean: 2.6cm). All defects were successfully covered with proximally based peroneus brevis muscle flaps combined with split-thickness skin grafts. All flaps healed with no complication or need for secondary surgery. The mean follow-up was18.8 months (range 12-32 months). CONCLUSION: Proximally based peroneus brevis muscle flap is a good alternative for reconstruction of lateral malleolar region defects with reliable blood supply, short surgical time, and minimal donor site morbidity.
