  • Patent number: 5993452
    Abstract: A cerclage system for securing a fractured or weakened bone within a patient's body is provided. In a preferred embodiment the cerclage system includes a band formed to encircle the bone. Typically the band will be fabricated from a material having a high tensile strength such as a metal wire. A jacket supports the band in a spaced relationship from the bone. The jacket is resorbed by the patient's body.

  • Patent number: 5810821
    Abstract: A bone fixation screw system and method of utilization thereof is provided for a bone having first and second sections with a fracture interface there between. A preferred embodiment of the bone fixation screw system includes a side plate having a first part for placement adjacent the bone second section and a second part angled from the first part providing a barrel. The barrel is adapted for insertion into a transsectionally extending bore into the bone in at least the second section of the bone. A lag screw is also provided for positional retention of the first section of the bone with respect to the second section of the bone. The lag screw also has a first part of a resorbable material for threaded connection of the lag screw within the bore of the bone in at least the first section of the bone, the lag screw having a second part connected with the first part made from a stronger nonresorbable material.

  • Patent number: 5611802
    Abstract: A method and apparatus for resecting bone includes an anterior femur resection guide assembly for performing an anterior femur osteotomy, a distal femur resecting guide assembly for performing a distal femur osteotomy, a compound posterior femur-chamfer resection guide assembly for performing an anterior femur osteotomy, and a tibia resection guide assembly for performing a proximal tibia osteotomy. The anterior femur resection guide assembly, the distal femur resecting guide assembly, the tibia resecting guide assembly, and the compound posterior femur-chamfer resection guide assembly each includes a capture plate subassembly which restricts lateral movement of a saw during resection. The distal femur resecting guide assembly and the tibia resecting guide assembly also include subassemblies for verifying the correct positioning of a distal femur and proximal tibia osteotomies.
