METHOD AND APPARATUS FOR PERFORMING MULTIDIRECTIONAL TIBIAL TUBERCLE TRANSFERS

摘要

A method for performing a multidirectional tibial tubercle transfer, comprising: positioning a jig against the anterior portion of the tibia, the jig comprising first and second cutting guides, wherein the first and second cutting guides simultaneously converge towards one another as they extend (i) distally down the tibia, and (ii) posteriorly towards the tibia; cutting first and second saw cuts into the tibia, wherein the first saw cut is aligned with the first cutting guide and the second saw cut is aligned with the second cutting guide; attaching an extender to the jig, wherein the extender comprises a third cutting guide, wherein the third cutting guide simultaneously converges towards the first cutting guide as the third cutting guide extends (i) distally down the tibia, and (ii) posteriorly towards the tibia; cutting a third saw cut into the tibia, wherein the third saw cut is aligned with the third cutting guide; freeing a first bone block from the tibia, wherein the first bone block is formed between the first saw cut and the second saw cut, and freeing a second bone block from the tibia, wherein the second bone block is formed between the first saw cut and the third saw cut; and transferring the position of the first bone block relative to the tibia. Apparatus for performing a multidirectional tibial tubercle transfer, comprising: a jig for positioning against the anterior portion of the tibia, the jig comprising first and second cutting guides, wherein the first and second cutting guides simultaneously converge towards one another as they extend (i) distally down the tibia, and (ii) posteriorly towards the tibia; and an extender for attaching to the jig, wherein the extender comprises a third cutting guide, wherein the third cutting guide simultaneously converges towards the first cutting guide as the third cutting guide extends (i) distally down the tibia, and (ii) posteriorly towards the tibia.
