An orthopedic implant retrieval kit which, when assembled, provides a shipping and handling container for explanted orthopedic devices which will protect individuals handling the container from the material in the container, and which will meet the appropriate regulations for shipping of potentially biohazardous material. The kit includes at least three plastic bags, at least two containers, a box, at least one foam insert, instructions and labels. The method involves assembling the kit components into a container for shipment.

A method and apparatus for the fixation of bone fractures, limb lengthening, and the correction of deformities uses an improved composite plastic carbon fiber ring that is formed in a mold, or machined with a stepped end portion that allows half rings to be assembled in a common plane. The method can use a mold wherein multiple rings can be formed by stacking the rings with a Teflon layer therebetween and wherein circumferential braid reinforcement of carbon fiber adds strength at the circumferential inner and outer curved surfaces of the rings and half rings.

An instrument for determining the variation in tension of a ligament graft extending between first and second proposed fixation sites positioned on first and second articulated bones, respectively, comprises a yoke which carries a device for securing the yoke to one of the first and second bones. A yoke plate is rotatably carried by the yoke. A main housing is adapted for connection to the yoke plate. A sled is slidably carried by the main housing. The sled is adapted for connection to the ligament graft. A mechanism is provided for adjusting the position of the sled relative to the housing so as to place a desired degree of tension on the ligament graft. A transducer is associated with the mechanism for adjusting for determining changes in tension, if any, from the desired degree of tension as the first and second bones are moved relative to one another.
