Abstract:
Objective:To investigate the clinical effect of free posterior tibial artery perforator flap in repair of forefoot soft tissue defect.Methods:From January 2017 to January 2021, a retrospective study was conducted on 13 patients with forefoot soft tissue defect, metatarsal head exposed, and forefoot transverse arch integrity, including 9 males and 4 females. The age was (40.0±13.0) years old. Cause of injury: 8 cases of traffic accident injury, 5 cases of heavy object smashing injury. Seven cases had forefoot skin defect and toe damage, and 6 cases had forefoot skin avulsion injury, open toe fracture with tendon, blood vessel and nerve injury. The wound area was 4.5 cm×3.0 cm-8.0 cm×6.0 cm. VSD treatment was performed in the first stage, and free posterior tibial artery perforator flap was used for the second stage. The flap area was 5.5 cm×4.0 cm-9.0 cm×7.0 cm. Outpatient reviews scheduled at 1, 2, 3, and 6 months after surgery, through outpatient clinic, telephone or WeChat. The flaps were evaluated according to appearance, texture, sensory recovery, and the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot function scoring system.Results:All 13 flaps survived. The follow-up lasted for 6 to 24 months. The feet were in good shape, walking with weight beries, and the flaps had satisfactory appearance without wear and tear. Five cases were S 3, 6 were S 2, and 2 were S 1. According to AOFAS ankle-hindfoot function score, 4 had excellent scores, 7 were in good, and 2 in fair. Conclusion:The free posterior tibial artery perforator flap has relatively constant perforators, and the pedicle of the middle and upper perforators is longer, and the flap can build part of the sensation. Posterior artery perforator flap is a good flat for repairing the soft tissue defects of the metatarsal head of the forefoot.
