COPAL® exchange G hip spacers provide patients, undergoing a two-stage revision procedure for an infected total joint, a temporary implant to 1) allow for partial weight bearing and 2) provide an approximate natural range of motion. The devices also maintain a patient's soft tissue and joint space, preventing further complications such as muscular contraction. COPAL® exchange G hip spacers are placed into the joint to maintain normal joint space and alignment. They provide patient comfort and limited mobility while the infection is being treated. COPAL® exchange G hip spacers are made with bone cement containing gentamicin. Gentamicin reduces the risk for bacterial colonization of the device and is released into the fluid surrounding the joint. COPAL® exchange G hip spacers are temporary joint prostheses designed to temporarily replace an infected implant during a total hip or knee arthroplasty and provide the patient with limited mobility and predictable, consistent local antibiotic release. COPAL® exchange G hip spacers are intended for single-use and are supplied sterile.
A sterile short-term substitute for an infected total hip prosthesis that provides a means for limited mobility/weight-bearing of the patient following surgical excision of the infected device. It also functions as a carrier for antibiotic drugs for their local delivery within the periprosthetic space. This temporary device includes femoral and acetabular components typically made of metallic and synthetic polymer materials, polymethylmethacrylate (PMMA), and antibiotic bone cement. Following infection resolution and device explantation, another permanent total hip prosthesis is implanted.
