Bipolar hemiarthroplasty systems are currently widely employed for the treatment of femoral neck fractures. Disassembly of bipolar femoral prosthesis, however, occurred in three patients during the closed reduction of the dislocated hips. Of 168 patients who underwent bipolar hemiarthroplasties between September 1999 and June 2002, eight hips (4.7%) were dislocated wna three hips (1.8%) were disassembled. All of the three patients were hospitalized in the psychiatric floor because of dementia, schizophrenia or depression. In all cases, open reductions were required, and hip brace was used after the reoperations. No breakage was found in femoral components. The mechanism of disassembly was considered impingement between the outer head and acetabulum during the closed reduction. Although prevention is important for dislocation, gentle and careful reduction should be required in the management of the dislocated bipolar heads.
