Vascular preservation during arthroscopic osteoplasty of the femoral head-neck junction: a cadaveric investigation.

Purpose: The goal of this study was to evaluate the risk of vascular injury with arthroscopic osteoplasty of the femoral head-neck junction in a cadaveric model.

Methods: Eight fresh-frozen cadaveric pelvi were used for arthroscopic osteoplasty of a predetermined 150 degrees arc of resection along the anterior femoral head-neck junction. Postoperatively, injection studies of the deep femoral arteries were performed on all specimens to identify local extravasation of neoprene latex before polymerization as a reproducible indicator of vascular injury.
