Abstract PDF: PURPOSE
To evaluate the clinical results of bipolar hemiarthroplasty in elderly patients more than 65 years of age with a femoral neck fracture.
MATERIALS AND METHODS
Forty-six bipolar hemiarthroplasties in 43 patients more than 65 years of age which could be followed more than 3 years were included in this study. The clinical outcomes were evaluated using Harris hip score, pain score and support score. The radiological results were analyzed by femoral stem loosening and bipolar cup migration.
RESULTS
The average Harris hip score was 88.7 (62~96) points. An excellent score was recorded in 34 cases, good in 7 cases, fair in 3 cases and poor in 2 cases. The average pain score was 39.3 points and there were no pain in 20 cases, slight pain in 17 cases, mild pain in 6 cases and moderate pain in 2 cases. The average support score was 9.6 points and 32 patients could walk without the use of any assistive devices. Two cases were converted to total hip arthroplasty due to femoral stem loosening with or without bipolar cup migration.
CONCLUSION
For the early ambulation and functional recovery of elderly patients with femoral neck fracture, bipolar hemiarthroplasty was considered as one of recommendable methods.

The Treatment of Unstable Intertrochanteric Fractures with Dynamic Hip Screw and Trochanter Stabilizing Plate: Sang Won Park, Soon Hyuck Lee, Dae Hee Lee, Jong Won Chung, Gi Won Choi; J Korean Fract Soc 2005;18(4):359-363. Published online October 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.4.359

PURPOSE
To analyze the effect of treatment of unstable intertrochanteric fractures with dynamic hip screw and additional trochanter stabilizing plate.
MATERIALS AND METHODS
Among twenty three cases of unstable intertrochanteric fractures treated with DHS and additional TSP between January 2002 to December 2004, seventeen cases over sixty years old were reviewed with minimal follow up of one year. We analyzed the type of fracture by AO classification, the age of patient, sex, the cause of trauma in seventeen cases. We evaluated the lag screw slippage, the change of neck-shaft angle and lateral displacement of greater trochanter, the period of union by comparison of last follow up radiographs with immediate postoperative radiographs. The fixation failure is defined that displacement of lag screw tip is more than 3 mm or cut out of the screw from the femoral head.
RESULTS
The period of union was average 12.8 weeks. The lag screw slippage was average 8.22 mm. The change of neck-shaft angle was average 2.66 degree. No lateralization of greater trochanter was noted in twelve cases, but five cases showed average 0.8 mm (range: 0.5~1 mm) of lateral displacement of greater trochanter. There was not fixation failure.
CONCLUSION
In unstable intertrochanteric fracture, the addition of a TSP to the dynamic hip screw can decrease a change of neck shaft angle, a lag screw slippage, and prevent lateral displacement of greater trochanter.
