COPAL® exchange G hip spacer is a temporary hip spacer implant as part of two-stage septic endoprosthesis revision based on bone cement. COPAL® exchange G hip spacer contains gentamicin. Gentamicin reduces the risk for bacterial colonization of the device and is released into the fluid surrounding the joint. COPAL® exchange G hip spacer is intended for single-use and is supplied sterile.COPAL® exchange G hip spacer is made of fully formed polymethylmethacrylate (radiopaque PMMA with gentamicin) and contains an inner stainless steel (AISI 316L) reinforcing structure. It contains the X-ray contrast medium calcium carbonate. To improve visibility in the surgical field, it has been colored with chlorophyll-copper-complex (E141).
A prefabricated device made of orthopaedic bone cement [e.g., polymethylmethacrylate (PMMA)], with an appropriate antibiotic, that is temporarily placed into a joint space to function as a carrier for the local delivery of antibiotic drugs and to prevent bone-on-bone contact and contraction of soft-tissue during surgical treatment of an infected joint. The shape and size of the device is modified to fit the joint space. This non-weight-bearing spacer remains in place until the infection clears; it is then removed and replaced with a conventional joint prosthesis. This is a single-use device.
