Extensor Tendon Gliding Surface Reconstruction Using Adipoascia Extended Free Anterolateral Thigh Flap - Case Report -

Purpose: In reconstructing a defect on the dorsum of the hand, there are many cases of extensor tendons exposed or even missing. The repaired or reconstructed tendons need relevant gliding environment for good functional recovery. The anterolateral thigh flap offers a vascular fascial component with large amounts that can be used for covering exposed tendons and we report a unique case of single-stage hand dorsum and gliding surface reconstruction. Methods: A 35-year-old man had severe post-traumatic scarring in his left dorsal hand and coverage of the flap with split-thickness skin graft has been done before. After scarred skin excision and extensor tendon graft for missed part, a free anterolateral thigh adipofascial flap was used to resurface the hand dorsum and to reconstruct a two-layer gliding surface of the extensor tendons. The extensor tendons were wrapped in the fascial component with the fat layer inside. Results: He had an uneventful postoperative course without infection, dehiscence and flap necrosis. Good overall functional recovery and tendon excursion were observed. He was also satisfied with postoperative appearance. Conclusion: A free anterolateral thigh adipofascial flap was used successfully for reconstruction of a two-layer tendon gliding surface to treat a patient with severe scarring in the dorsal hand.
