ELBOW RECONSTRUCTION INSTRUMENTS

摘要

Instrumentation for elbow reconstruction, specifically, for repairs of the ulnar collateral ligament (UCL). The instrumentation provides for precise formation of sockets and tunnels along with easy suture/graft passage while accommodating all forms of elbow UCL reconstruction techniques. A V-drill guide is provided with a handle and two drill sleeves having intersecting trajectories for creating an intersecting V-shaped bone tunnel in the ulna. An adjustable humeral guide has an adjustable arm with an arc shape, and a peg and a block extending from each end of the adjustable arm. The peg is shaped to fit within an already-formed humeral socket. The block allows a drill to pass through and form other tunnels which intersect with the originally-formed tunnel at various positions.

主权项

1. A surgical instrument for ulnar collateral ligament reconstruction, comprising:
an elongated substantially rigid member with a longitudinal axis, a proximal end and a distal end; a handle located at the proximal end of the elongated member; and two drill sleeves located at the distal end of the elongated member, the drill sleeves being symmetrically disposed relative to the longitudinal axis of the member and a mirror image of each other, the drill sleeves being non-parallel to the longitudinal axis of the elongated member and forming a structure with a V shaped configuration so that trajectories of the two drill sleeves form an angle of about 50 to about 75 degrees, a distal end of each of the drill sleeves being provided with teeth for gripping bone, and each drill sleeve having a lumen for receiving a drill, obturator, or a pin.
