Avascular necrosis (AVN) occurs when there is a loss of blood supply to the bone that results in the eventual death of the bone. Left untreated, the end result is an eventual collapse of the affected bone. AVN can occur in all joints, but it commonly occurs in the femoral head and at that stage total hip arthroplasty is routinely performed. This technique treats the AVN with decompression and by 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, the instruments allow for treatment of AVN lesions of the femoral head. Once the lesion is decompressed, Arthrex offers multiple biologic options to backfill the socket and cavity.
