加压螺纹钉治疗股骨颈骨折的体会

Compression Screw for the Treatment of Femoral Neck Fractures

本文总结了我院应用加压螺纹钉内固定治疗新鲜股骨颈骨折１９例，１６例进行了随访，随访时间６个月～４年。手术效果满意，优良率为９３％，其中５例头下型骨折亦顺利愈合．至今未发现股骨头缺血性坏死及不愈合者．我们认为加压螺纹钉内固定的牢固性及稳定性均优于三翼钉固定。本文对手术方法、该钉的结构及生物力学原理进行了探讨。

19 cases of fresh fractures of the neck of femur were treated with compression screw.internal fixation. Follow-up was done in 16 cases in a period of 6 months to 4 years,The result of the operation was satisfactory. The total effective rate was 93%,and 5 cases of subcapital type fractures also obtained union.There were no avascular necrosis of the femoral head or non-union among them. Furthermore, compression screw provided with greater firmness and stability than Smithpetersen nail. The operation method,architectural mechanics,and biomechanics principles were discussed in this paper.
