An osteotomy plate for maintaining the spacing of a wedge-like opening in bone, the osteotomy plate comprising: a body having a front side and a back side; a key extending out of the back side of the body for disposition in a keyhole formed in the bone along the wedge-like opening; and a plurality of mounting holes for receiving fixation screws therein, the mounting holes being formed in the body such that when the key is disposed in the keyhole, the mounting holes direct the fixation screws into bone on either side of the wedge-like opening.

Apparatus for performing an open wedge, high tibial osteotomy

Method and apparatus for performing an open wedge, high tibial osteotomy

Apparatus for performing an open wedge, high tibial osteotomy, the apparatus comprising: a wedge-shaped implant for disposition in a wedge-shaped opening created in the tibia, wherein the wedge-shaped implant comprises a hole extending therethrough; a fixation screw for extending through the hole and securing the wedge-shaped implant to the tibia; and a locking mechanism for releasably locking the fixation screw to the wedge-shaped implant. The fixation screw comprises: a shaft having a distal threaded portion and a proximal threaded portion, wherein the distal threaded portion and the proximal threaded portion are characterized by different thread pitches.

Apparatus for performing an open wedge, low femoral osteotomy, the apparatus comprising an osteotomy guide, a hinge pin and an osteotomy implant, the osteotomy guide comprising: anterior and posterior tissue shields having (i) openings for receiving the hinge pin and defining the hinge pin axis, and (ii) profiles configured to enable fluoroscopic alignment of the hinge pin axis parallel to the sagittal plane of the patient, a cutting guide comprising a cutting slot for defining a cutting plane extending parallel to, and through, the hinge pin axis, and a drill guide comprising a hole for forming a guide hole in the femur which extends substantially perpendicular to the cutting plane, the hinge pin comprising an elongated body, and the osteotomy implant for positioning in a wedge-shaped opening formed about the cutting plane and for receiving a screw extending through the guide hole.

Method and apparatus for performing an open wedge, low femoral osteotomy

A method for performing a high tibial, dome osteotomy to adjust the lateral and/or angular disposition of the tibial plateau relative to the lower portion of the tibia, the method comprising: forming an arcuate osteotomy cut in the tibia to subdivide it into upper and lower portions; manipulating the upper and lower portions to adjust their lateral and/or angular dispositions relative to one another; forming a pair of keyholes along the osteotomy cut; forming a keyhole slot to connect the two keyholes; forming a fixation hole in the tibia for each keyhole; providing an implant comprising a pair of keys connected by a bridge, each key comprising a bore for receiving a fixation screw therein; inserting the implant so that the keys are disposed in the keyholes, and so that the bores of the keys are aligned with the fixation holes; and inserting fixation screws through the bores of the keys and into the fixation holes of the keyholes so as to stabilize the upper and lower portions of the tibia.
