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.

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.
