Are Reverse Flow Fasciocutaneous Flaps an Appropriate Option for the Reconstruction of Severe Postburn Lower Extremity Contractures?

Abstract

Full thickness burns involving the lower extremity can result in severe contractures, which impair extremity functions if they are not managed with proper treatment and rehabilitation. After release of postburn contracture of the knee, ankle, and metatarsophalangeal joints, defects often require coverage by flaps. Twelve distally based reverse flow flaps were performed for lower-extremity reconstruction after release of postburn flexion contractures. All of the patients were male and their age ranged from 20 to 23 years, with a mean age of 21. After the release of the contractures, 3 flaps were used based on the location of the contractures. The reverse flow anterolateral thigh flap was used for knee reconstruction (n = 4, 33%). The reverse flow sural flap was used for ankle reconstruction (n = 4, 33%), and the reverse flow medial plantar flap was used for metatarsophalangeal reconstruction (n = 4, 33%). The sizes of the flap varied from 2 to 17 cm wide and 3 to 18 cm in length. All defects were covered successfully. Reverse fasciocutaneous tissue transfer to reconstruct the soft tissue defects provide early motion. Sufficient contracture release is achieved without displacement of anatomic landmarks. The reverse-flow flap is a reasonable and reliable choice for each joint level in the lower extremity.
