Abstract: Handles for athletic equipment, such as baseball bats. The handles include two different portions, or sides, each configured to achieve different results. A first portion has a flared shape and no knob, and is configured to interface with the hypothenar side of a batter/user's hand in a way that it promotes the gliding of the handle/knob over his or her hypothenar area, hamate bone and other anatomic areas included in such. A second portion has a least a partial knob and is configured to interface with the user's little finger with a protuberance that engages the little finger, wherein the engagement of the little finger facilitates better grip, a pivot point for proximal part to glide across hypothenar eminence of hand and better performance of the bat (or other athletic equipment) being used.

Abstract: A method of revising a graft in a bone tunnel including unpinning a graft ligament support block from within a bone tunnel in a host bone, withdrawing the graft ligament support block from the bone tunnel to create a vacated bone tunnel, advancing a graft ligament support block into the vacated bone tunnel, and pinning the graft ligament support block within the bone tunnel. In one embodiment, the graft ligament support block includes a body having a graft hole and a transverse fixation pin hole extending through the body. The graft hole and the transverse fixation pin hole extend substantially perpendicular to the longitudinal axis of the body. An installation tool can be provided for inserting the graft ligament support block into the bone tunnel.

Abstract: A method and apparatus for reconstructing a ligament using a graft ligament support block which comprises a body, and a graft hole and a transverse fixation pin hole extending through the body, with both the graft hole and the fixation pin hole preferably extending substantially perpendicular to the longitudinal axis of the body. A graft ligament is looped through the graft hole, and the support block is advanced into the bone tunnel, with the two free ends of the looped graft ligament extending back out the bone tunnel. Next, a transverse tunnel is formed in the host bone, with the transverse tunnel being aligned with the fixation pin hole. Then the support block is secured in place by pinning the support block within the tunnel, i.e., by advancing a fixation pin along the transverse tunnel in the host bone and into the fixation pin hole in the support block.
