Covering defects at the lower leg and foot is a common challenge in reconstructive surgery. A flap is often required, and free flaps are widely used. The posterior tibial perforator-based flap constitutes a valuable option in this situation. The objectives of this study were to evaluate the reliability of the posterior tibial perforator-based flap, report any complications, and describe the outcomes, with the goal of defining the indications of this flap in the treatment of lower limb defects. The posterior tibial perforator-based flap is a useful and reliable option for soft-tissue defect reconstruction at the leg and foot. Patients managed using a posterior tibial perforator-based flap to cover soft-tissue defects of the leg and foot were reviewed retrospectively. A physical examination was performed and radiographs obtained at the last postoperative follow-up visit. Thirteen patients with a mean age of 46.9 years (range: 25–73 years) were reviewed after a mean follow-up of 19.5 months (range: 16–63 months). The tissue defects were due to compound fractures in 10 patients and to postoperative complications in 3 patients. Mean flap size was 12.3cm by 6.2cm. The donor site was covered by a skin graft in 12 patients and closed primarily in 1 patient. The procedure was successful in 11 (85%) patients. The posterior tibial perforator-based flap is a method of choice for covering soft-tissue defects at the leg and foot. Careful patient selection and flawless technique contribute to minimise the failure rate. IV, retrospective study.
