[Dislocation-disassembly of bipolar hip arthroplasty--case report]

Bipolar hip arthroplasty dislocation is rare. A case of bipolar hip arthroplasty dislocation in patient treated because of femoral neck fracture was described. Patient had neurological problems. The arthroplasty was made with posterolateral approach. Disassembly of bipolar prosthesis occurred during closed reduction. Open reduction with bipolar head exchange was necessary. To avoid this complication reduction should be made in anesthesia with muscles relaxation.
