Abstract: Apparatus and method are described for interoperatively determining, during a trailing procedure conducted in connection with total hip arthroplasty, a combination of neck length and femoral head offset required in a femoral component for establishing appropriate hip mechanics in a prosthetic hip joint to be implanted at an implant site. A trial femoral head is coupled for selective movement relative to a femoral stem component to move the trial femoral head longitudinally and laterally relative to a predetermined direction among selected combinations of trial distance and trial offset to evaluate hip mechanics and determine interoperatively an appropriate combination of trial distance and trial offset corresponding to the combination of neck length and femoral head offset required in the prosthetic hip joint.

Abstract: The present invention provides a novel, optionally surfactant-free process for controlling particle number, particle size, and/or particle size distribution. The method of the invention also significantly improves monomer to polymer conversion rates, as well as, increases the level of polymer solids which can be emulsified/dispersed in water without polymer flocculation. Specifically, the improved process provides an aqueous dispersion of up to about 48% polymer solids in water in the absence of surfactant. The resulting fluoropolymers dispersions may be used in resin and coating applications.

Abstract: The invention pertains to benzocyclobutene resins having flame retardant properties. Such resins have a high glass transition temperature (Tg>250° C.), low moisture absorption, low dielectric constant, good mechanical properties, flame retardancy (meets or exceeds UL94 V-O and/or VTM-O requirements), and can be cast onto a reinforcement to prepare a laminate for use as a substrate for electronic circuitry. The flame resistant compound is reaction product of a halogen containing compound of the formulae R&Parenopenst; DA)n or R&Parenopenst; DA&Parenclosest;n R2 wherein R is a halogen containing aromatic group, a halogen containing aliphatic group or a combination thereof; R2 is hydrogen, an aromatic group, an aliphatic group or an combination of an aromatic group and an aliphatic group which may contain halogen atoms; DA is a Diels-Alder reactive diene or a group that can act as a dienophile in a Diels-Alder reaction; and n is greater than or equal to 1; with a benzocyclobutene compound.

Abstract: A femoral hip prosthesis comprises a main member, a modular member and a means for connecting the two. The main member has a stem portion and a body portion which are adapted for insertion into the intramedullary canal. The body portion has lateral, posterior, and anterior sides adapted to mate with the bone and has a medial side configured and dimensioned to receive a modular member. The modular member is chosen from a plurality of such members of various shapes and sizes and is adapted to fit accurately into the intramedullary canal, especially after the intramedullary canal has been deformed through the prior implantation of a prosthetic hip device.
