The Relationship between Limb-Length Discrepancy on Function, Dislocation, Pain and Acetabular Wear after Bipolar Hemiarthroplasty for Femoral Neck Fracture

ABSTRACT

PURPOSE: To evaluate the relationship between a limb-length discrepancy and the clinical and radiological outcomes after bipolar hemiarthroplasty for femur neck fractures in elderly patients. MATERIALS AND METHODS: Between August 2004 and January 2007, 60 out of 80 cases over 65 years who underwent cemented bipolar hemiarthroplasty for femur neck fractures with a more than 2 years follow-up were evaluated retrospectively by dividing the patients into two groups, > 5 mm (group 1) and 0.05). CONCLUSION: Limb-lengthening by hemiarthroplasty may be a cause of pain but with little effect on the overall functional outcome.
