METHODS AND APPARATUS FOR DETERMINING PIN PLACEMENT DURING HIP SURGERY

PROBLEM TO BE SOLVED: To provide new apparatuses and methods for placing a drill guide accurately by placing a guide pin more rapidly and accurately in femur head resurfacing during hip surgery.SOLUTION: A mold which contains an aperture for guiding a drill at the desired location and angle is prepared, and during surgery the mold can be quickly and accurately positioned on the exposed femur head. Then, a drill bit can be inserted through the aperture and an opening for a pin can be drilled into the femur head. The mold can have a unique contoured surface adapted to fit to the femur head in a single unique position such that the opening is made in a unique desired position. The apparatuses and methods facilitate faster, more accurate surgery and are less invasive.
