摘要: A modular trial neck segment is utilized for trialing a hip prosthesis for a total hip arthroplasty. The modular trial neck segment is preferably, but not necessarily, utilized for trialing a hip prosthesis for a total hip arthroplasty. The trial neck segment includes a mount attachable to a stem or broach, and a neck that is translatable on the mount for providing various neck offsets with respect to the mount and/or broach. Neck offset is changed via movement of the neck in a single plane of motion. This facilitates the use of the subject invention in minimally invasive arthroplasty wherein working dimensions are small. The present design replicates the biomechanics of the neck region of the implant. The mount and slidable neck provide a plurality of neck offsets and/or neck lengths for trialing a final prosthesis in a single device.
