Abstract
Kits and methods for use in intraoperative trailing of hip prostheses to determine an appropriate length for the femoral neck component of a prosthetic hip joint, are described. A kit for use in selecting a femoral neck component of an orthopaedic joint prosthesis kit comprises a first (10) and a second (110) broach. Each of the first and second broaches has a neck connection element comprising a projection (12, 112) extending from a proximal surface (14, 114) of the broach, each projection having a length (L). The projection on the first broach has a different length than the projection on the second broach. The kit also includes a trial femoral neck (30) component having a neck connection element in the form of a recess (36) in a distal surface (34). The recess is configured to mate with the projection on each of the first or second broaches such that mating of the trial femoral neck component with the first broach provides an assembly with a first neck length, and the mating of the trial femoral neck component with the second broach provides an assembly with a second neck length.
