DEMONSTRATIVE USE ONLY. NOT FOR USE IN PATIENTS OR FOR SALEMuller 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.
