Repair of wounds in popliteal fossa scar with perforator flaps of gastrocnemius medial head / 中华烧伤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of perforator flaps of medial head of gastrocnemius muscle on repairing popliteal fossa scar wounds.</p><p><b>METHODS</b>Ten patients with scar in popliteal fossa hospitalized from January 2005 to January 2010 were repaired with perforator flaps of medial head of gastrocnemius muscle. The scar was resulted from burn in 8 patients, and from operation in 2. The duration of the scar was 3 months to 11 years, and area of the scar ranging from 6 cm × 3 cm to 10 cm × 6 cm. Ultrasonic Doppler was used to detect the musculocutaneous perforator vessel of the medial sural artery at the position 10 to 17 cm from the fold of the popliteal fossa and 2 to 5 cm from the posterior midline before surgery. Then flap transplantation surgery was performed. Donor site wounds with width less than 5 cm were sutured directly, and those wider than 5 cm were repaired with skin transplantation.</p><p><b>RESULTS</b>All the flaps survived. Flap size ranged from 7 cm × 5 cm to 12 cm × 7 cm. All patients were followed up for 3 to 30 months, and the flaps were found to have a good appearance. Patients could walk with heavy load without lameness. The function of knee joint of the affected limb was the same as that of the opposite limb. No obvious depression was observed in donor sites.</p><p><b>CONCLUSIONS</b>The perforator flaps of medial head of gastrocnemius muscle can be used to repair the popliteal fossa scar wound with satisfactory result.</p>
