Core Decompression

Overview

Core decompression is used for cases of avascular necrosis (AVN) of the femoral head when there is no collapse of the femoral head. This is a salvage procedure to help preserve a patient’s native hip and avoid having a hip replacement. Dr. Shelton will perform his core decompression arthroscopically. Prior to the start of the hip arthroscopy, bone marrow aspirate concentrate (BMAC) is taken from the posterior aspect of the pelvis to be used later in the case. Next, a standard hip arthroscopy is performed to address any other intra-articular pathology. Multiple small drill holes are then made into the area of necrosis and then the BMAC is injected up one of the holes in an effort to restore blood flow to that area of the femoral head.

Potential Implications

Blood loss, infection, damage to nerves or blood vessel including numbness over the lateral (side) of the thigh, possible post-operative fracture if weight bearing performed too soon, deep vein thrombosis (DVT), continued collapse of the femoral head, and need for additional surgery.
