Abstract
Purpose
To evaluate outcome after cementless bipolar hemiarthroplasties using a standard(tapered, rectangular) stem for the treatment of above type A2 fractures in elderly patients.
Material and methods
We reviewed the records of 37 patients who underwent bipolar hemiarthroplasty between February 2006 and Feburuary 2010 in our hospital who were followed for more than two years after surgery. The mean patient age was 73.5 years old (range 64∼88 years old). 16 patients were men, and 21 patients were women. We evaluated the results by analyzing operation time, amount of bleeding, recovery of walking ability, complications and radiologic findings.
Result
The mean operation time was 75.3 minutes. The average total amount of bleeding was of 755.5 cc. At the last follow-up, 23 patients (62%) had recovered walking ability. Complications included a deep infection in one case, 1 cases of acetabular erosion, 2 cases of greater trochanter non-union. There were no revisions due to prosthesis loosening or another reason.
Conclusion
Cementless bipolar hemiarthroplasty using a tapered, rectangular stem can be an alternative treatment for type A2 intertrochanteric fractures in elderly patients so as to achieve earlier mobilisation.
