• Objective: Orthopaedic surgeons have various choices in their management of displaced intracapsular fracture of non-arthritic hips of rheumatoid arthritis patients. The purpose of this investigation was to assess the middle-term results of bipolar hemiarthroplasty (BHA) for displaced femoral neck fractures in the unaffected hips of rheumatoid arthritis patients.<BR>Methods: We retrospectively reviewed 9 rheumatoid arthritis patients (10 hips) who underwent hemiarthroplasty for the treatment of femoral neck fracture. All the patients were female, and the average age of patients was 66.8 years (range, 54 to 77 years) . The average follow-up period was 6.8 years (range, 5 to 12 years) . At 1 week after operation and at the latest follow-up, hip radiographs were made to evaluate any bipolar shell migration, measuring vertical distance from the teardrop line to the center of the inner-head of each prosthesis, the horizontal distance between the teardrop and the center of the inner-head, and the distance of the outer-head of each prosthesis from the Köhler's line.<BR>Results: Nine of the ten hips did not demonstrate any radiographic evidence of protrusion of the bipolar shell, and only one hip had radiographic evidence of moderate migration of the bipolar shell by 2 millimeters.<BR>Conclusion: Bipolar hemiarthroplasty may be an effective procedure of treatment for displaced femoral neck fractures in non-arthritic hips of rheumatoid arthritis patients.
