External hemipelvectomy pelvic ring stabilization: the unique application of chimeric lower extremity pedicled fillet flaps.

Reconstruction of large external hemipelvectomy oncologic defects of the proximal limb and trunk remains a formidable surgical challenge. Large pelvic defects can result in exposed bones, neurovascular structures, and surgical hardware due to a paucity of soft tissue coverage. When the size of a hemipelvectomy defect precludes coverage by local posterior- or anterior-based hemipelvectomy flaps, the use of other local flaps must be considered before resorting to free tissue transfer.

Use of the rectus abdominis muscle flap to fill a retroperitoneal defect following blast injury.

Wartime injuries from explosive devices have created the need for atypical responses to devastating and unusual injuries. We report a case of an explosive abdominal injury that produced a huge defect in the posterior abdominal wall which was ultimately repaired with a rectus abdominus flap, an usual use of this versatile muscle flap. The rectus abdominus muscle may be another tool available for the repair of wartime injuries.
