A femoral head resurfacing apparatus includes a cap of hemispherical shape and stabilization structure (e.g., one or more non-shear fixation bars) that inserts into slots cut into the femoral head, so that the cap remains substantially immovable other than due northerly. A method of resurfacing the femoral head of a hip joint includes removing longitudinal slots or holes of bone in the femoral head, and attaching a hemispherical cap to the head, the cap having non-shear fixation bars or other stabilizing structure for mating engagement with the slots or holes.
