[Design of the reduction fixator and its clinical application in treating fracture of lesser trochanter of femur].
OBJECTIVE
To discuss the clinical significance of the reduction and fixation for femoral lesser trochanteric fragment in treating the femoral comminuted intertrochanteric fractures.


METHODS
From January 2012 to December 2013,32 patients with intertrochanteric fractures were treated by surgery, and self-designed reduction fixators were used in the patients for the fixation of lesser trochanter of femur. There were 11 males and 21 females, ranging in age from 45 to 81 years old with an average of 64 years old. According to the Evans typing, 12 cases were type II, 13 cases were type III and 7 cases were type IV. Simple lag screw fixed in 19 cases and steel wire fixed in 13 cases. Hip joint function was evaluated according Harris score and the complications such as coxa adducta,cutting of femoral head and neck,implants breakage were observed.


RESULTS
Thirty-two patients were followed up from 9 to 24 months with an average of 13 months. Coxa adducta occurred in 1 case,no cutting of femoral head and neck occurred and implants breakage were found. The mean Harris score was 91.80 ± 3.05 in 32 patients.


CONCLUSIONS
The reconstruction and fixation for the posterior medial bone cortex continuity is a key factor on affect the stability of femoral intertrochanteric fracture. Self-designed reduction fixators can effective reduce and fix the lesser trochanter of femur, it has advantage of fast reduction and fixation, and simple operation.
