摘要： A multi-purpose measurement tool comprises an elongate beam and a slide. The elongate beam extends from a first end to a second end, and comprises a first fixed jaw, a second fixed jaw, and a track. The first fixed jaw extends from the beam at the first end. The second fixed jaw extends from the beam opposite the first jaw and spaced from the first end. The track extends across the elongate beam through the first end. The slide has a first end extending from the track and a second end extending into the track. The slide has a moveable jaw extending from the slide opposite the first fixed jaw. The slide can also have a front face and a back face, each face with readable measurement indicia thereon

摘要： Disclosed herein is a method of generating a computerized bone model representative of at least a portion of a patient bone in a pre-degenerated state. The method includes: generating at least one image of the patient bone in a degenerated state; identifying a reference portion associated with a generally non-degenerated portion of the patient bone; identifying a degenerated portion associated with a generally degenerated portion of the patient bone; and using information from at least one image associated with the reference portion to modify at least one aspect associated with at least one image associated the generally degenerated portion. The method may further include employing the computerized bone model representative of the at least a portion of the patient bone in the pre-degenerated state in defining manufacturing instructions for the manufacture of a customized arthroplasty jig. Also disclosed herein is a customized arthroplasty jig manufactured according to the above-described method. The customized arthroplasty jig is configured to facilitate a prosthetic implant restoring a patient joint to a natural alignment. The prosthetic implant may be for a total joint replacement or partial joint replacement. The patient joint may be a variety of joints, including, but not limited to, a knee joint.

摘要： A drill guide for determining the site for and drilling a tunnel in a tibia during an anterior cruciate ligament replacement procedure and method for using same are also disclosed. The drill guide utilizes a multiple-point anatomical reference system for determining the most favorable position for the tibial tunnel, based on isometry, freedom from impingement and desired ACL-PCL interaction. The drill guide further utilizes a removable guide bar to provide visual alignment of the drill guide relative to the coronal plane of the knee joint.

摘要： An apparatus and method for tibial fixation of a soft tissue graft includes a body having a first side and a second side. A first plurality of spikes extend from the second side of the body each having a first length. A second plurality of spikes extend from the second side of the body each having a second length where the first length is longer than the second length. The first plurality of spikes are operable to engage the bone without the second plurality of spikes substantially engaging the soft tissue graft to permit proper tensioning of the soft tissue graft. The method includes forming a tunnel in a bone and forming a counterbore substantially perpendicular with the tunnel. The soft tissue graft passes through the tunnel and the counterbore and is secured within the counterbore with an apparatus which is nested within the counterbore.
