Kits and methods for use in intraoperative trialling 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 and a second broach. Each of the first and second broaches has a neck connection element comprising a projection extending from a proximal surface of the broach, each projection having a length. 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 component having a neck connection element in the form of a recess in a distal surface. 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.

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 () and a second () broach. Each of the first and second broaches has a neck connection element comprising a projection () extending from a proximal surface () 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 () component having a neck connection element in the form of a recess () in a distal surface (). 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.

The present invention is a rigid, solid bodied stringed instrument having an electrical pickup embedded in at least one predetermined position within the stringed instruments solid body to pick up the actual wood tones and resonance of the rigid solid body. The electrical pickup is comprised of a piezoelectric transducer embedded between a planar brass surface and a planar ceramic surface. In the preferred embodiment, the pickup transducer is circular in shape and embedded within the stringed instrument's solid body adjacent the strings which span the body. The embedded piezoelectric transducer requires a fraction of the area required by traditional electric coil pickups. In an alternate preferred embodiment, the pickup transducer is embedded within a transducer housing. The housing is then embedded within the solid body of a stringed instrument adjacent the strings. By including the piezoelectric transducer within its own housing the pickup can be sold separately in the aftermarket and incorporated in solid body stringed instruments.
