Endoscopically guided subchondral intraosseous osteotomy and bone graft stabilization for osteonecrosis of the femoral head.
The endoscopically guided core decompression approach used with the Titanium Hip Tool™ Locking Plate Bone Graft Stabilization System (BGSS) is specifically designed to assist those surgeons who determine that core decompression and nonvascularized bone-grafting is the best treatment modality for a given patient.
The endoscopic approach enhances the surgeon’s ability to identify and debride necrotic bone within the femoral head without having to increase the diameter of the core tract beyond 9mm or having to use the soft-tissue dissections characteristic of “the lightbulb” or “the trapdoor” procedures. The Titanium Hip Tool™ Locking Plate and compression screw stabilize the fresh autogenous cancellous bone (preventing its micromotion) thereby assisting its incorporation into the surrounding viable host bone within the femoral head.
The goal of the endoscopic approach is to extend the debridement process up to vascularized bone, i.e., prepare the host bed for bone graft while maintaining a narrow core tract in the femoral neck. Additionally, the Titanium Hip Tool™ Locking Plate and compression screw stabilize the fresh autogenous cancellous bone and prevent its micromotion, as would be required in primary bone healing.
