Objective To evaluate the effectiveness of repairing or reconstructing defects of the forefoot. Methods Between February 2006 and February 2013, 57 patients with defects of the forefoot were treated. There were 41 males and 16 females with an average age of 38.9 years (range, 19-68 years). The disease causes included motor vehicles crush injury in 28 cases, crashing injury in 17 cases, and machine extrusion injury in 12 cases. The left side was involved in 25 cases and the right side in 32 cases, with a mean disease duration of 4.7 hours (range, 0.5-75.0 hours). Defect located at the 1st metatarsus in 9 cases, at the 5th metatarsus in 8 cases, at the 1st and the 2nd metatarsus in 16 cases, at the 4th and 5th metatarsus in 11 cases, at multiple metatarsus and the forefoot in 13 cases. The bone defect ranged from 2.5 cm×1.9 cm×1.4 cm to 13.3 cm×11.2 cm×2.7 cm. The soft tissue defect ranged from 12.4 cm×6.3 cm to 27.2 cm×18.7 cm. The iliac bone or vascularized iliac bone or vascularized fibula bone was used to rebuild the arch of the foot, and free flap was used to repair defects of the forefoot. The donor site was sutured directly or covered with skin graft. Results Venous crisis and partial necrosis occurred in 3 and 2 flaps respectively, which healed after symptomatic treatment. The other flaps and grafted skins survived, and wounds healed primarily. Fifty-one cases were followed up 1.5-2.5 years (mean, 2.1 years). The appearance was excellent and the feeling of the flap recovered at different levels. The two-point discrimination was 8.4-19.8 mm (mean, 13.7 mm) at 1.5 years after operation. According to upper extremity functional evaluation standard by hand surgery branch of Chinese Medical Association, sensation recovered to S2 in 6 cases, to S3 in 18 cases, and to S4 in 27 cases. The patients began to walk with weight loading at 2-6 months after operation (mean, 3.9 months). The bone healing time was 3-6 months (mean, 4.2 months). Based on American Orthopaedic Foot and Ankle Society (AOFAS) standards, the results were excellent in 19 cases, good in 24 cases, fair in 7 case, and poor in 1 case, and the excellent and good rate was 84.3%. Conclusion It is a good solution to treat defects of the forefoot to use iliac bone or vascularized iliac bone or vascularized fibula bone for rebuilding the arch of the foot and use free flap for repairing defect.
