Abstract

PURPOSE
To evaluate the effect of the sliding hip screw with wiring of lesser trochanter for the treatment of unstable trochanteric fractures.
MATERIALS AND METHODS
we analysed retrospectively 39 cases between 1995 and 1999. All cases were followed up for more than 1 year. Using modified Watson-Jonson approach, we performed reduction of the fracture as anatomically possible extent.
RESULTS
Bony union was obtained in average 6 months. Nonunion with metal failure occurred in one case. The average sliding of lag screw was 11mm. The average change of neck-shaft angle (NSA) was 1.8degrees respectively. Satisfactory NSA was achieved in 33 cases except 2 cases of varus and 4 cases of valgus both exceeding 10degrees.
CONCLUSION
The sliding hip screw with wiring of lesser trochanter is a useful option for unstable trochanteric fractures because of its initial stability as buttress effect on posteromedial cortex to allow early ambulation.
