Abstract:

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.

Abstract:

An overlapped test specimen fixture operates as a template to precisely position pairs of standardized coupons in predetermined overlapped relation to demarcate standardized bonding sites for application of adhesive systems to be tested. The fixture includes a caul plate bounded by an integral, elevated shoulder having opposed sidewalls and endwalls. The exposed surface is configured as a bi-level, flat support surface having upper and lower surfaces that support the coupons in overlapping relation. The opposed sidewalls are operative to precisely position overlapped coupons lengthwise wherein such coupons demarcate a predetermined overlap length. The fixture also includes locator rails extending upwardly from support surfaces which are operative to precisely position the overlapped coupons transversely. The precisely positioned, overlapped coupons define standardized bonding sites for application of the adhesive system to form a test specimen. Securing members are utilized to temporarily secure test specimens in immobile combination with the support surfaces.
