Reverse sural fasciocutaneous flap with a cutaneous pedicle to cover distal lower limb soft tissue defects: experience of 109 clinical cases

摘要

class="Heading">Background class="Para">Soft tissue defects over the mid- and distal third tibia, heel, dorsum and plantar aspect of the foot and over the medial, lateral and posterior aspect of the ankle are a common scenario in clinical orthopaedic practice. In this article, we describe the utility of the reverse sural fasciocutaneous flap with a cutaneous pedicle in 109 clinical cases with distal lower limb soft tissue defects. class="Heading">Materials and methods class="Para">A total of 109 patients were operated on for moderate (5–15?cm) and large (more than 15 cm) soft tissue defects at various sites along the lower limb including foot, heel and sole with the reverse sural fasciocutaneous flap. The defects were secondary to trauma (61 cases), diabetic ulcers (12 cases), post-traumatic scar contracture (8 cases), venous ulcer (4 cases), wound dehiscence (10 cases), leprotic non-healing ulcer (1 case), post-infective wound (1 case), radiation-induced ulcer following radiotherapy for synovial cell sarcoma (1 case), post-fibromatosis excision (1 case), post-dermatofibrosarcoma excision (1 case), post-heel melanoma excision (1 case) and actinomycosis foot (1 case). Patients were assessed for flap uptake and healing of defects. class="Heading">Results class="Para">Among the 102 cases analysed, 81 were male and 21 female with an average age of 32.7?years. The average size of the flaps was 148.10?±?59.54?cm2. The flap healed uneventfully in 89.21?% of patients. Edge necrosis occurred in 9 cases. Donor site regrafting was required in 7 patients. class="Heading">Conclusion class="Para">The reverse sural fasciocutaneous flap with a cutaneous pedicle is a quick, versatile, easy and safe soft tissue defect coverage technique to cover most of the soft tissue defects of the lower limb in common orthopaedic practice and does not require any microvascular repair, though it may be cosmetically unappealing in a few cases. class="Heading">Level of evidence class="Para">IV (Case series)
