Abstract: An avascular neucrosis instrument includes a drill guide member, an extension member attached to an end of the drill guide member, an indexing member attached to the drill guide member, and a flexible drill member extending along the drill guide member and exiting the drill guide member at an angle adjacent the extension member. In another embodiment, the extension is removed from the end of the drill guide member and another extension member is attached to an end of the flexible drill member. As a result, the flexible drill member can be used to form a plurality of channel arrays for the distribution of blood supply to a femoral head.
