Abstract

Abstract:

BACKGROUND: Internal fixation is commonly used in an early stage of intertrochanteric fractures of the aged worldwide, and can apparently reduce complications and fatality rate. The commonly used internal fixators contain proximal femoral nail anti-rotation and dynamic hip screw, whose comparison is current research hotspot.
OBJECTIVE: To evaluate the hip function and stability after internal fixation with proximal femoral nail anti-rotation and dynamic hip screw in repair of intertrochanteric fractures of the aged.
METHODS: A total of 64 aged patients with intertrochanteric fractures were enrolled in this study, and assigned to dynamic hip screw group (n=30) and proximal femoral nail anti-rotation group (n=34). The fracture reduction and healing were evaluated using anterioposterior and lateral X-ray films. Operation time, intraoperative blood loss, complication rate, healing time and postoperative hip function were compared and analyzed between the two groups, and then assessed in accordance with Sander’s scoring system.
RESULTS AND CONCLUSION: Compared with dynamic hip screw group, operation time, intraoperative blood loss, healing time and complication rate after treating unstable intertrochanteric fracture (Tronzo-Evans III, IV and V types) showed significant advantages in the proximal femoral nail anti-rotation group (P < 0.05). Hip function restored better, and the complication rate of stable intertrochanteric fracture (Tronzo-Evans I and II types) was lower after treatment in both groups (P > 0.05). These data show that the effects of proximal femoral nail anti-rotation were better than that of dynamic hip screw for treatment of intertrochanteric fractures, and hip function recovered better. Moreover, proximal femoral nail anti-rotation had biomechanical stability, especially for unstable fracture.
