Various local and distant flaps have been used to repair pelvic defects, including sartorius, rectus abdominis, rectus femoris, tensor fascia lata, vastus lateralis, gracilis, and omentum, each with benefits and disadvantages. The pedicled internal oblique rotational muscle flap has been described to cover pelvic wounds but may be underutilized. We present our experience with 5 pedicled internal oblique flaps in 4 patients (3 male, 1 female). The mean patient age was 32 years (23-47 years), and the mean follow-up was 8 months. All patients required coverage of the lateral pelvis after failure of conservative measures. There were no major complications. One patient experienced decreased sensation in the lateral femoral cutaneous nerve distribution, which resolved fully within 3 months. The internal oblique muscle provides local soft-tissue coverage with a predictable blood supply, and its proximity to the pelvis offers an alternative for reconstruction of lateral pelvic defects, with minimal associated morbidity.
