摘要： Processes are set forth for forming high strength thermoplastic polymer bone fixation devices used, for example, in orthopedic surgery, where "strength" is quantified in terms a given device's pullout strength, tensile modulus, shear strength and breaking torque strength. Products of the aforementioned process are contemplated by the invention as well, with both "bioabsorbable" devices, for example, screws which are absorbable in an animal body and do not need to be removed after the bone in which they are inserted has healed; and non-bioabsorbable devices being described.

摘要： A new cutting tip and a very simple method for making the tip are given. The tip has no flutes but has a built-in chip clearance. It is self-drilling, self-tapping, and self-locating and can be positioned on a threaded or unthreaded member. When it is the tip on a suture anchor, it maximizes holding strength of the anchor.

摘要： A medical implant made of polymeric material having an increased oxidation resistance is formed by a method including the steps of placing a resin powder in a sealed container. A substantial portion of the oxygen is removed from the sealed container by either a vacuum, an oxygen absorbent or by flushing with inert gas. The container is then repressurized with a gas such as nitrogen, argon, helium or neon so that long term storage may be possible. On use, the resin is transferred to a forming device which both melts and forms the resin in an oxygen reduced atmosphere to produce a polymeric raw material such as a rod or bar stock. The medical implant is then formed from this raw material annealed and sealed in an air-tight package in an oxygen reduced atmosphere. The implant is then radiation sterilized and thereafter annealed in the package for a predetermined time and temperature sufficient to form cross-links between any free radicals in neighboring polymeric chains.

摘要： Methods and apparatus are set forth for preparing and delivering bone cement from a powdered polymer component and a liquid monomer component by simultaneously injecting the powdered and liquid components, stored in separate component chambers, into an evacuated mixing chamber under the effect of the vacuum; by uniformly mixing the components in the mixing chamber (to thoroughly wet the powder); and by delivering the cement formed by the polymerization process, as needed in an operative setting, utilizing a single ready to use device. The uniform mix is achieved by simultaneously subjecting the contents of the component chambers to the effects of the mixing chamber's vacuum via separate one way nozzles, interconnecting the component chambers to the mixing chamber, which cause the powder to be broadcast and liquid to be sprayed into the mixing chamber. The nozzles are designed and oriented in a predetermined manner (depending on the type and quantity of the constituent bone cement components being mixed), to cause the components to interact at a preselected distance within the mixing chamber, to assure uniform powder saturation and a thorough mix which yields a homogeneous reaction product.

摘要： A prosthesis with an integral proximal spacer is described. The prosthesis has a base element with a textured surface to aid in adhesion to bone cement. The integral spacer has a generally tripod shape. A top circumferential portion at least partially surrounds the proximal end of the prosthesis, and three legs extend distally along the length of the prosthesis. Also disclosed is the process for making the prosthesis and spacer, which preferably involves injection molding of PMMA.

摘要： A femoral component for a hip prosthesis has a distal portion defining a central longitudinal axis. The component has a generally conically shaped mid-shaft portion and a proximal portion with a shape based on the reamer and a shaped chisel used by the surgeon to prepare the proximal metaphysis and medullary canal. The proximal portion is shaped in a manner wherein a cross-section taken perpendicular to the central axis has a medial side formed as a first circular arc, a corner of the cross-section formed by the posterior and lateral sides as a second circular arc with a center on the central axis. The posterior side is arcuate and concave and tangent to the first and second circular arcs, with the anterior side being arcuate and convex.
