Among the many devices available for the internal fixation ofthe trochanteric fractures of the femur, the sliding-screw plate method has gained considerable acceptance. however, the procedure is demanding to be more delicate and skillfull, and
its
problems are not infrequent especially in the elderly patients with unstable fractures.
A retrospective study of roentgenograms and charts was made of the reochanteric fractures in the elderlhy, treated with the dynamic Hip Screw; to investigate the relationships between the type of fracture, the type of reduction, the presence of
osteoporosis, the implant position, and technical complications and re-operations.
@ES The results were as follows:
@EN 1. Technical complications occurred in 7 unstable cases (17.9%)
2. Complication rates were 14.3% in cases of medial reduction : 21.5%, anatomical reduction : and 50.5%, lateral reduction.
3. More unstable fractures and technical complications were noted in cases with osteporosis.
4. 4. Technical complications were more frequent in cases of the lag screw tip inseted into the
superior portion of the femoral head.
5. unstable fractures (mean;9.1mm) collapsed more than stable cases (mena:3.6mm).
6. The change of neck-shaft angle was most noticeable in unstable fractures with anatomic reduction.
