Abstract

BACKGROUND:

Anti-rotation ability and fracture stability of using simple dynamic hip screws for femoral intertrochanteric fractures fixation is poor.

OBJECTIVE:

To observe the biomechanical characteristics of dynamic hip screws and anti-rotational screws for treatment of femoral intertrochanteric fractures.

METHODS:

Thirty-eight patients who used dynamic hip screws and anti-rotational screws for femoral intertrochanteric fracture were selected. Thirty-two patients who received reduction and fixation with dynamic hip screws and anti-rotational screws for femoral intertrochanteric fracture were retrospective analysed.

RESULTS AND CONCLUSION:

Totally 32 cases were followed up for average 12.6 months (ranged from 6 to18 months). All the patients obtained bone union in average 18.1 weeks. There were no cases with implant loosening or refracture. According to Harris rating scale, the excellent and good rate was 90.6%, evaluation 21 cases in excellent, 8 cases in good, 3 cases in average and 0 case in poor. Internal fixation of dynamic hip screws and anti-rotational screws are suitable for femoral intertrochanteric fracture and this method have characteristics of large definitive rotational stability and rigid fixation.
