CLINICAL OUTCOMES OF GASTROCNEMIUS MUSCLE FLAP RECONSTRUCTION FOR EXPOSED TIBIAL DEFECTS IN THE PROXIMAL HALF OF THE LEG
Main Article Content
Abstract
Objectives: To evaluate the clinical outcomes of gastrocnemius muscle flap reconstruction for exposed tibial defects in the proximal half of the leg.
Methods: A retrospective descriptive study was conducted on seven patients with exposed tibial defects in the proximal half of the leg who underwent reconstruction using gastrocnemius muscle flaps at the National Burn Hospital Le Huu Trac between September 2023 and March 2025. Outcomes were assessed based on flap survival, postoperative complications, functional recovery, and patient satisfaction at 6 months after surgery.
Results: Traffic accidents were the most common cause of injury (71.4%). All patients presented with wound infection, including two cases (28.6%) of osteomyelitis. The medial gastrocnemius muscle flap was the most frequently used flap (57.1%). Complete flap survival was achieved in all cases. One patient developed recurrent infection resulting in skin graft loss and wound dehiscence. At 6 months postoperatively, all patients were able to walk on a flat surface, and 71.4% were able to run. Most patients reported satisfactory functional and aesthetic outcomes.
Conclusion: The gastrocnemius muscle flap is a safe and effective reconstructive option for the treatment of exposed tibial defects in the proximal half of the leg, particularly in cases complicated by wound infection or osteomyelitis.
