Functional and Aesthetic Outcomes of Reconstruction of Soft-Tissue Defects of the Heel with Free Flap

Abstract

Objective: To evaluate functional and aesthetic outcomes of the reconstruction of soft-tissue defects of the heel with microsurgical techniques using a free radial forearm flap and an anterolateral thigh flap. Patients and methods: The study included 25 patients, 15 males and 10 females, with a mean age of 34.3 ± 10.4 years, with soft-tissue defects of the heel. Of them, 11 patients whose defects were of size between 5 and 10 cm in their largest dimension were treated using a free radial forearm flap, and 14 patients whose defects were of size larger than 10 cm in their largest dimension were treated using a free anterolateral thigh flap.Post-operatively, avoidance of weight-bearing and walking was required for 8 to 10 weeks. At the end of the follow-up, all patients underwent functional, aesthetic and sensation evaluation in addition to assessment of patient satisfaction. Results: The median follow-up period was 24 months. The causes of the defect were trauma (14 patients), neuropathic ulcer (8 patients) and neoplasia (3 patients). The size of the defect ranged from 5 × 6 cm to 14 × 24 cm. Four patients had calcaneal fracture. By the end of the follow-up period, 21 cases showed complete success, whereas 2 flaps failed, one in each flap type, and the remaining two flaps showed partial loss of the edges (anterolateral thigh flaps). Failure was due to venous congestion (one patient) and ischaemia (one patient). Eighteen patients were satisfied with their aesthetic appearance, functional outcome and flap sensation. Conclusion: Reconstruction of large heel defects, using radial forearm and anterolateral thigh free flaps, provides acceptable functional and aesthetic outcomes.
