摘要： Apparatus for the fixation of bone fractures, limb lengthening, and the correction of deformities comprises an improved composite plastic carbon fibre ring that is formed in a mould, or machined with a stepped end portion that allows half rings to be assembled in a common plane. In the manufacture of the apparatus a mould may be used wherein multiple rings can be formed by stacking the rings with, eg. a polytetrafluoroethylene layer therebetween and wherein circumferential braid reinforcement of carbon fibre adds strength at the circumferential inner and outer curved surfaces of the rings and half rings.

摘要： 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 (16) which carries a device for securing the yoke to one of the first and second bones. A yoke plate (18) is rotatable carried by the yoke. A main housing (60) is adapted for connection to the yoke plate. A sled (78) is slidably carried by the main housing. The sled is adapted for connection to the ligament graft. A mechanism (85, 91) 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 (87) 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.
