Dissociation and implantation of Exeter femoral instrumentation during total hip arthroplasty.

Proprietary femoral plug introducers are routinely used to insert intramedullary plugs during total hip arthroplasty. The cement restrictor pin from an Exeter intramedullary plug introducer may become detached during insertion of the cement restrictor plug, or during sponge packing of the femur We suggest some precautions that should be taken to prevent this from occurring and advise that the patient is unlikely to experience any long-term adverse reactions to the presence of the restrictor pin in the intramedullary canal.
