En bloc resection of extra-peritoneal soft tissue neoplasms incorporating a type III internal hemipelvectomy: a novel approach.

Background: A type III hemipelvectomy has been utilized for the resection of tumors arising from the superior or inferior pubic rami.

Methods: In eight patients, we incorporated a type III internal hemipelvectomy to achieve an en bloc R0 resection for tumors extending through the obturator foramen or into the ischiorectal fossa. The pelvic ring was reconstructed utilizing marlex mesh.

Open anterior approaches for lumbar spine procedures.

With the advent of anterior lumbar interbody fusion (ALIF) and artificial discs as common procedures for the treatment many spinal problems such as pseudoarthrosis, degenerative disc disease and internal disc disruption from trauma, anterior exposure has become an increasingly popular procedure for the general, thoracic, urologic and vascular surgeon. Despite this, the body of literature describing this procedure is lacking. Dividing the approach for anterior spinal surgery into the thoracolumbar, mid-lumbar, and lumbosacral regions, we describe the basic techniques and anatomy needed to perform these open approaches, specifically, repairs of disc spaces T12-L2, L2-5, and L5-S1, respectively.
