Muller Stem Type, 48mm Head, 120 mm Stem Length. Temporary implant which main function is to preserve the articular space during 2 Stage Revision Arthroplasty. Aids in treatment of infection that emerged due to the implant of hip replacement prosthesis. The hip spacer with gentamicin has a surgical steel core coated with radiopaque (barium sulfate) bone cement (PMMA) with antibiotic (gentamicin base). This is a long-term use implant, intended to be used for a maximum period of 180 days.
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.
