System for treating proximal humeral fractures and method of using the same

摘要

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 system for treating a proximal humeral fracture with a humeral implant having at least one hole defined therethrough, the system comprising:
a longitudinal rod member configured to be at least partially received within the humeral shaft, wherein the longitudinal rod member comprises a first portion, a second portion, and a coupling member disposed between the first and second portions; wherein the longitudinal member defines a first plurality of holes that are offset radially and axially along the first portion of the longitudinal rod member from one another and a second plurality of holes located distally of the first plurality of holes and spaced axially apart from one another along the second portion of the longitudinal rod member; a humeral implant having at least one hole defined therethrough; and a jig assembly comprising 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 first and second portion of the longitudinal rod member without overlap of said first plurality of holes of the first portion of the longitudinal rod member, the jig assembly further comprising an arm extending from the coupling member of the jig assembly and a pin guide arranged substantially perpendicularly to the arm, wherein the pin guide defines at least one hole therethrough that is configured to guide placement of at least one hole in the humeral shaft, wherein the at least one hole formed in the humeral shaft is configured to align with the at least one hole in the humeral implant when said implant is placed in the humeral shaft after the longitudinal rod member is removed from the humeral shaft, such that the jig assembly is configured to locate the position of the humeral implant in the humeral shaft; and wherein the at least one hole of the jig assembly is configured to align with at least one of said second plurality of holes of the second portion of the longitudinal rod member and guide placement of the at least one hole in the humeral shaft such that the longitudinal rod member and the jig assembly are configured to locate the position of the humeral implant in the humeral shaft.
