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 < 5 mm (group 2) of limblengthening. Harris hip score, the activity of daily living(ADL), dislocation rate, pain by a visual analogue scale (VAS) and acetabular wear by radiographic measurements were analyzed. RESULTS: For each group, the Harris hip score in group 1 and 2 was 80.0 and 76.2, respectively. The ADL in group 1 and 2 was respectively, 36 and 29 preoperatively, 56 and 52 postoperatively. The visual analogue scale in group 1 and 2 was 3.53 and 2.23 (P=0.002), respectively, and acetabular wear was encountered in 6 and 8 cases in group 1 and 2, respectively. The VAS score was significant. There was no difference in acetabular wear and dislocation between the two groups (P>0.05). CONCLUSION: Limb-lengthening by hemiarthroplasty may be a cause of pain but with little effect on the overall functional outcome.
