- Purpose
The reconstruction of defects around the knee and the proximal third of the leg necessitates thin, pliable skin with a stable and sensate soft tissue cover. This study analyzed the use of a proximally based sural artery flap for the coverage of such defects.
Methods
This prospective clinical interventional study involved 10 patients who had soft tissue defects over the knee and the proximal third of the leg. These patients underwent reconstruction with a proximally based sural artery flap. The study analyzed various factors including age, sex, etiology, location and presentation of the defect, defect dimensions, flap particulars, postoperative complications, and follow-up.
Results
There were 10 cases, all of which involved men aged 20 to 65 years. The most common cause of injury was trauma resulting from road traffic accidents. The majority of defects were found in the proximal third of the leg, particularly on the anterolateral aspect. Defect dimensions varied from 6×3 to 15×13 cm2, and extensive defects as large as 16×14 cm could be covered using this flap. The size of the flaps ranged from 7×4 to 16×14 cm2, and the pedicle length was 10 to 15 cm. In all cases, donor site closure was achieved with split skin grafting. This flap consistently provided a thin, pliable, stable, and durable soft tissue cover over the defect with no functional deficit and minimal donor site morbidity. Complications, including distal flap necrosis and donor site graft loss, were observed in two cases.
Conclusions
The proximally based sural fasciocutaneous flap serves as the primary method for reconstructing medium to large soft tissue defects around the knee and the proximal third of the leg. This technique offers thin, reliable, sensate, and stable soft tissue coverage, and can cover larger defects with minimal complications.

Abstract

- Purpose
Defects involving the ankle and foot are often the result of road traffic accidents. Many such defects are composite and require a flap for coverage, which is a significant challenge for reconstructive surgeons. Various locoregional options, such as reverse sural artery, reverse peroneal artery, peroneus brevis muscle, perforator-based, and fasciocutaneous flaps, have been used, but each flap type has limitations. In this study, we used the distally based lateral supramalleolar flap to reconstruct distal dorsal defects of the foot. The aim of this study was to analyze the efficacy of the flap in reconstructing distal dorsal defects of the foot. The specific objectives were to study the adequacy, reach, and utility of the lateral supramalleolar flap for distal defects of the dorsum of the foot; to observe various complications encountered with the flap; and to study the functional outcomes of reconstruction.
Methods
The distal dorsal foot defects of 10 patients were reconstructed with distal lateral supramalleolar flaps over a period of 6 months at a tertiary care center, and the results were analyzed.
Results
We were able to effectively cover distal foot defects in all 10 cases. Flap congestion was observed in two cases, and minor graft loss was seen in two cases.
Conclusions
The distally based lateral supramalleolar flap is a good pedicled locoregional flap for the coverage of distal dorsal foot and ankle defects of moderate size, with relatively few complications and little morbidity. It can be used as a lifeboat or even substitute for a free flap.
