Pedicled ALT-flap for soft tissue reconstruction in the trochanteric area

Abstract

Purpose: Coverage of soft tissue defects following surgery at the trochanteric area is challenging. Revision surgery in case of compromised wound healing may lead to soft tissue defects requiring reconstruction with pedicled or free flaps. Previous access to the hip joint may jeopardize neurovascular structures relevant to the flap. In this study, we evaluated if pedicled anterior lateral thigh (ALT) flap is a valueable option for soft tissue reconstruction in this situation. Methods: In this retrospective study, five patients were included. Defect etiology was tumor resection in one case, screw osreosynthesis in another case and total hip arthroplasty in three cases. All patients underwent reconstruction by proximal pedicled anterior lateral thigh (ALT) flap. Results: Pedicled ALT flap was a safe procedure in all cases. One patient showed delayed wound healing with need for additional surgery. No further complications were observed. Conclusion: Pedicled ALT flap transfer represents a reliable option for soft tissue coverage in the trochanteric area after primary surgery such as hip arthroplasty, osteosynthesis or tumor resection.
