Patent ID: 10639050

Abstract:
A method for interosseous ligament reconstruction (e.g., of a scapholunate or lunotriquetral ligament) includes drilling holes through both of the bones to allow for a graft to be placed on the volar and dorsal aspects of the bones, replicating the normal anatomic structure of the interosseous ligament, while requiring only an incision on the dorsal side of the wrist. The method includes using a drill guide that directs the drill to place a drill hole from dorsal to volar (front to back) in the bone, while making sure the drilled hole is within the joint on the volar side. The drill guide includes a hollow guide tube to advance a drill through, the hollow tube movably coupled to a shaft of the drill guide with a distal end that generally aligns with the distal end of the hollow tube. The shaft can have a sharp end that the drill will meet if passed through the drill guide, the sharp end of the drill guide being either hollow or solid, and can serve to release part of the wrist capsule (volar extrinsic carpal ligaments) from the bone in order to keep the drill hole within the wrist joint (and not outside of the joint).
