Biomet Inc manufactures a variety of internal fixation devices intended to aid in the alignment and stabilization of fractures to the skeletal system until healing has occurred. Biomet Kirschner Wires (K-wires) are rigid yet malleable wires with penetrating tips such that they may be inserted through tissue and into bone to alow for traction of bone fragments as desired or for alignment quides for other bone fixation implants. These wires are available in multiple diameters, same length and unthreaded (smooth) versions. Biomet Kirschner Wires are single use and provided in both sterile configurations. Unless supplied sterile, metallic internal fixation devices must be sterilized prior to surgical use.

StageOne™ Select Hip Cement Spacer Molds with stainless steel reinforcement stems, adapters and inserts are indicated for use to mold a temporary hemi-hip replacement for skeletally mature patients undergoing a two-stage revision procedure due to a septic process. The temporary prosthesis is molded using Refobacin Bone Cement R, assembled and inserted into the femoral medullary cavity following removal of the existing femoral and acetabular replacement implants and debridement. The device is intended for use in conjunction with systemic antimicrobial antibiotic therapy (standard treatment approach to an infection). The hemi-hip prosthesis made from the StageOne™ Select Cement Spacer Molds is not intended for use more than 180 days, at which time it must be explanted and permanent devices implanted or another appropriate treatment performed (e.g. resection arthroplasty, fusion, etc.). Due to the inherent mechanical limitations of the hemi-hip prosthesis material (Refobacin Bone Cement R), the temporary hemi-hip prosthesis is only indicated for patients who will consistently use traditional mobility assist devices (e.g. crutches, walkers) throughout the implant period.

The Compress and Mini Compress Anti-Rotation Spindles are components of the Compress Segmental Femoral Replacement System and Compress Segmental Humeral Replacement System. The Anti-Rotation Spindles attach to an anchor plug and a proximal/distal femoral/humeral component to serve as a method of fixing a segmental joint replacement to a patient's host bone. The Anti-Rotation Spindles contain several conical washers which allow a compressive load to be applied at the prosthetic implant-bone interface at the time of device insertion. The Anti-Rotation Spindles also include a series of holes around the spindle collar to allow placement of pins to prevent rotation of the component. The purpose of this submission is the update of the surgical techniques associated with the Compress and Mini Compress Anti-Rotation Spindles to revise the recommended pin selection range for use with the Anti-Rotation Spindles.
