三棱内固定器治疗股骨颈骨折疗效观察

THE OBSERVATION OF THE THERAPEUTIC EFFECTS OF TRIPRISMED INTERNAL FIXATOR ON THE TREATMENT OF FEMORAL NECK FRACTURE

为探讨股骨颈骨折内固定的有效方法 ,以自行设计的三棱内固定器与三翼钉、多枚骨圆针、单枚空心螺纹钉、三枚加压螺纹钉内固定法相比较进行临床观察 ,共治疗 148例 ,随访 1～ 8年 ,结果显示三棱内固定器治疗组骨折愈合率及功能恢复优良率为 86.1% ,股骨头坏死率为 13.9% ;而三翼钉、多枚骨圆针 ,单枚空心螺纹钉、3枚加压螺纹钉的功能恢复优良率分别为 61.3%、78.2 %、70 .8%、79.4% ,股骨头坏死率分别为 38.7%、2 1.7%、2 9.2 %、2 0 .6%。认为三棱内固定器治疗股骨颈骨折具有创伤小 ,疗效高 ,操作简便 ,固定牢固可靠 ,抗旋转、抗剪切力性能好等优点 。

To explore the effective methods of the internal fixator for femoral neck fracture, we compared a kind of self-made triprismed internal fixator with other internal fixators of trifin nail, multiple osseous pin, single hollow screw, three pressor screws. We altogether treated 148 cases, and the following-up time was 1～8 years. The results showed that the fine rate of the functional restoration of the triprismed internal fixator group were 86.1 %, the necrosis rate of femoral head was 13.9 %; while the fine rates of the functional restoration of the trifin nail group, several osseous pin group, single hollow screw group, three pressor screws group were 61.3%, 78.2%, 70.8%, 79.4% respectively, the necrosis rates of femoral head were 38.7%, 21.7%, 29.2%, 20.6%, respectively. Therefore triprismed internal fixator has the benefits of small trauma, good therapeutic effect, simple operation, firm fixation, anti-rotating on treating femoral neck fracture, it is an ideal method of treating femoral neck fracture.
