Background: This study evaluates the effects of wire tension band ventral compression wiring technology paired with artificial femoral head replacement according to the different types of intertrochanteric fractures of the greater trochanter in elderly patients. Methods: Thirty-eight patients with unstable intertrochanteric fractures of the femur treated with artificial femoral head replacement between January 2015 and August 2019 were included. According to the fracture line of the greater trochanter, a new classification system was proposed. Type A fractures include transverse fractures from the greater trochanter tip to the base (2 patients). Type B fractures include oblique fractures from the greater trochanter tip to the base (according to the fracture line direction, type B was further divided into types B1 [4 patients], and B2 [24 patients]). the fracture line of type C fractures runs from the greater trochanter to near the femur end (8 patients). Different wire tension belt ventral compression wiring technologies were used for each fracture type. The Harris hip function score, Parker activity score, and hip pain were evaluated during the follow-up period. Fracture healing and prosthesis positioning, loosening, and dislocation were evaluated using radiographs. Results: The average follow-up period was 28.6 ± 5.8 months. Deep vein embolism was noted in one patient, heterotopic ossification in another, and steel wire fractures in another. All patients had satisfactory fracture healing and femoral prosthesis positioning and no chronic pain. The mean Harris hip function score was 7.21 ± 2.58 preoperatively and 84.74 ± 3.82 at the final follow-up (F = -48.13, P < 0.001).Conclusion: The use of different wire tension band ventral compression wiring technology based on different types of femoral rotation fractures combined with artificial femoral head replacement in elderly patients with unstable intertrochanteric fractures results in favorable clinical outcomes. |
