Bone plate system for opening wedge proximal tibial osteotomy
First Claim
1. A method of correcting a deformity by performing an osteotomy in a bone at an osteotomy site using a plurality of bone plates, each bone plate having two ends, a width, a proximal side, and a distal side, the distal side having a projection with a length and a depth, and a tool having a distal end and a proximal end, the distal end including a wedge having a tapered thickness and two prongs, the two prongs being separated by a distance greater than the bone plate width, the method comprising the steps of:
- (a) forming an incision over the osteotomy site;
(b) resecting the bone from a first side of the bone to a second side of the bone, leaving a bony hinge on the second side;
(c) wedging open the resection by inserting the tool to a depth at which the deformity is corrected;
(d) selecting a bone plate having a projection length equal to the thickness of the tool at the deformity-correcting depth;
(e) placing the selected bone plate between the two prongs of the tool;
(f) inserting the projection into the resection opening such that plate spans the resection, the two ends of the plate contacting the first side of the bone;
(g) securing the two ends of the plate to the bone on the first side of the bone so as to maintain the projection within the resection opening.

Abstract
A system for performing proximal tibial or femoral osteotomies. The system includes a plurality of bone plates of various sizes, and a calibrated wedge tool for opening a resected tibial wedge and determining the size plate to use in the osteotomy.

11. A method of correcting a deformity by performing an osteotomy in a bone at an osteotomy site using a bone plate having two ends, a width, a proximal side, and a distal side, the distal side having a projection with a length and a depth, and a tool having a distal end and a proximal end, the distal end including a wedge having a tapered thickness and two prongs, the two prongs being separated by a distance greater than the bone plate width, the method comprising the steps of:

(a) resecting the bone from a first side of the bone to a second side of the bone so as to leave a bony hinge on the second side; (b) opening the resection by inserting the tool into the resection to a depth at which the deformity is corrected; (c) placing the bone plate between the two prongs of the tool; and (d) inserting the projection of the bone plate into the open resection such that the bone plate spans the open resection, two ends of the plate contacting the first side of the bone. - View Dependent Claims (12, 13)
