四种内固定方法治疗新鲜股骨颈骨折的临床分析(附138例报告)

Clinical Analysis of Four Internal Fixation for Fracture of Femoral Neck (A report of 138 cases)

目的 评价四种内固定方法治疗新鲜股骨颈骨折的疗效。方法 采用三根骨圆针 ,折断式螺钉 ,空心加压螺纹钉和双头加压螺纹钉治疗新鲜股骨颈骨折 ,获随访 13 8例。按股骨颈骨折愈合率及股骨头坏死率 ,结合术后功能恢复评级。结果 骨圆针和双头加压螺钉对GardonⅡ型骨折疗效满意 ;折断式螺钉和空心加压螺钉对各型骨折均有较好疗效。四种内固定器材在影响骨折愈合方面无统计学差异。结论 四种内固定器材只要适应症选择正确 ,操作规范 。

Objectives To evaluate the effects of four kind of internal fixations for femoral neck fracture. Methods From 1987 to 1997,three steinmann pins,breaking compression screws, cannulated compression screws and both-end screwed compression nails were used to treat fracture of femoral neck. Of those 138 cases, Gardon II in 47 cases, Gardon III in 51 cases and Gardon IV in 40 cases, had been followed up with an average of 5 2 years. The results were divided into excellent, good, fair and poor, based on the recovery, bony union and head necrosis. Results Three steinmann needles and both-end screws could give satisfactory outcome for Gardon II; breaking and cannulated compression screws were suited to total one. Bone unin rate of four internal fixations did not difference significantly. Conclusions As long as right indications are chosen and operative skills are standrded,the four internal fixations can gain a satisfactory treatment response.
