Distally Based Peroneal Artery Perforator-Plus Fasciocutaneous Flap to Reconstruct Soft Tissue Defect Combined With Chronic Osteomyelitis in the Lateral Malleolus

Distally based peroneal artery perforator-plus fasciocutaneous (DPAPF) flaps are widely used to reconstruct soft tissue defects of the lower extremity. Treatment for soft tissue defect combined with chronic osteomyelitis in the lateral malleolus has rarely been reported. The aim of this study was to elaborate the superiority of the DPAPF flap and provide referential experience for using the DPAPF flap in this situation. Between June 2010 and December 2017, soft tissue defects in the setting of chronic osteomyelitis in the lateral malleolus were reconstructed with DPAPF flaps in 17 patients. After thorough debridement, the defect was repaired with the DPAPF flap, and patients subsequently followed an antibiotic regimen for 6 weeks. Follow-up periods for all patients were at least 24 months. The reconstruction outcomes and the satisfaction of the 17 patients were evaluated. Of the 17 flaps, 16 survived uneventfully, except one occurrence of partial necrosis. No infection occurred in the follow-up period. In the study, 17 patients except one were satisfied with flap appearance. All the patients were satisfied with the reconstruction outcomes. In a one-stage procedure, the use of DPAPF flaps is ideal for reconstructing soft tissue defects in the setting of chronic osteomyelitis in the lateral malleolus.
