System for treating proximal humeral fractures and method of using the same
View Patent ↗Various embodiments of the present invention provide systems and methods for treating a proximal humeral fracture. A system according to one embodiment includes a longitudinal member configured to be received within the humeral shaft. The system includes a jig assembly configured to be coupled to the longitudinal member, wherein the jig assembly includes at least one hole defined therethrough that is configured to guide placement of at least one hole in the humeral shaft, and wherein the hole formed in the humeral shaft is configured to align with at least one hole in the humeral implant such that the jig assembly is configured to locate the position of the humeral implant in the humeral shaft.
1. A method for treating a proximal humeral shaft fracture with a humeral implant having at least one hole defined therethrough, the method comprising:
inserting at least a distal portion of a longitudinal rod member within the humeral shaft, wherein the distal portion of the longitudinal rod member includes a plurality of holes extending therethrough and spaced axially apart from one another;
coupling a jig assembly comprising at least one hole extending therethrough to a coupling member included on the longitudinal rod member, wherein the coupling member is disposed on the longitudinal rod member between the at least distal portion and a proximal portion of the longitudinal rod member and configured to abut against a proximal end of the humeral shaft, wherein the at least one hole of the jig assembly is configured to align with at least one of the plurality of holes of the distal portion of the longitudinal rod member;
wherein the proximal portion of the longitudinal rod member comprises a plurality of holes that are offset radially and axially along the longitudinal member from one another, wherein the method further comprises inserting an orientation pin in one of the first plurality of holes to determine the version of the humeral implant in the humeral shaft;
wherein the jig assembly comprises a coupling member configured to mate with the coupling member of the longitudinal rod member for removably securing the jig assembly to the longitudinal rod member between the proximal and distal portions of the longitudinal rod member without overlap of the plurality of holes of the proximal portion of the longitudinal rod member, the jig assembly comprises an arm extending from the coupling member of the jig assembly and alongside of the humeral shaft, and wherein the at least one hole extends through the arm in a perpendicular direction to the direction of the arm;
forming at least one hole in the humeral shaft guided by the at least one hole of the jig assembly and the at least one of the plurality of holes of the distal portion of the longitudinal rod member; and
after forming the at least one hole in the humeral shaft, removing the longitudinal rod member from the humeral shaft and inserting at least a distal portion of the humeral implant within the humeral shaft, wherein the at least one hole formed in the humeral shaft is configured to align with at least one hole extending through the humeral implant such that the jig assembly is configured to locate the position of the humeral implant in the humeral shaft.
2. The method of claim 1 , wherein the humeral implant is a trial humeral implant, the method further comprising inserting the trial humeral implant within the humeral shaft, and inserting a cortical pin through the at least one hole in the humeral shaft and the at least one hole defined the trial humeral implant.
3. The method of claim 2 , further comprising sliding a fin clamp assembly over the cortical pin and fastening the fin clamp to the trial humeral implant.
4. The method of claim 3 , further comprising unfastening the fin clamp and removing the cortical pin and the trial humeral implant, inserting a final humeral implant within the humeral shaft, inserting the cortical pin through the at least one hole in the humeral shaft and at least one hole defined the final humeral implant, and sliding the fin clamp assembly over the cortical pin such that the fin clamp is fastened to the final humeral implant in the same way as the fin clamp was fastened to the trial humeral implant.
