Avascular Necrosis/OCD Expandable Reamer

Avascular necrosis (AVN) occurs when a loss of blood supply to the bone results in the eventual death of the bone. Left untreated, the end result is the collapse of the affected bone. Although AVN can occur in any joint, it commonly occurs in the femoral head. Routine treatment of femoral head AVN is total hip arthroscopy, a technique that involves removing the necrotic bone, which is typically found 5-mm to 10-mm below the articular cartilage. Using arthroscopic and fluoroscopic guidance as a reference, reamers allow for treatment of femoral head AVN lesions. Once the lesion is decompressed, Arthrex offers multiple biologic options to backfill the socket and cavity.
