The reconstruction of soft-tissue defects of the ankle and foot usually requires free-tissue transfer. Although certain local flaps have been described for the reconstruction of these injuries, their utility may be compromised by significant crush injury or the size and location of the defect. Part of the rectus abdominis muscle, the segmental rectus abdominis free flap, is ideally suited for this use because of the muscle's versatility, reliability, and negligible donor deformity when harvested through a low transverse abdominal incision. Seven patients reconstructed with this flap are presented, and the technique is discussed. All patients have been successfully reconstructed with preservation of the ankle and foot. At present, all patients are fully or partially weight-bearing. The segmental rectus abdominis free flap is recommended for the reconstruction of such wounds.
踝部和足部软组织缺损的重建通常需要游离组织移植。尽管已有一些局部皮瓣用于这些损伤的重建，但严重挤压伤、缺损的大小和位置可能会影响其效用。腹直肌的一部分，即节段性腹直肌游离皮瓣，因其肌肉的多功能性、可靠性以及通过低位横向腹部切口切取时供区畸形可忽略不计，非常适合用于此。本文介绍了7例采用该皮瓣重建的患者，并讨论了相关技术。所有患者均成功重建，踝部和足部得以保留。目前，所有患者均能完全或部分负重。推荐使用节段性腹直肌游离皮瓣来重建此类伤口。
