自动加压器内固定治疗老年性股骨干骨折6例

１９９３年５月～１９９７年１２月，我们应用自动加压器［１］内固定治疗老年性股骨干骨折６例，经临床观察，效果满意，现报道如下。１　临床资料本组６例，男４例，女２例；年龄６０～７８岁，平均６７岁；股骨中１／３骨折４例，下１／３２例；陈旧性骨折６例，其中５例为骨牵引复位失败，１例以前曾作内固定２次因钢板断裂致骨不连，合并膝关节严重僵硬。２　治疗方法显露骨折端：按常规手术切口或按原切口入路，取出原有固定器，切除骨端全部瘢痕和骨痂，恢复骨的原形，骨痂保护好用于填充骨缺损区，凿通骨髓腔。安置自动加压器：固定…

Senile Fracture of Femoral Shaft Treated with the Automatic Press Apparatus and Dirigation After Operation

An automatic press apparatus developed by Professor Zhou Conglin and Zhou Xihua was used by 6 patients with senile fracture of femoral shaft. The apparatus was applied to help them with dirigation the next day after the open reduction and internal fixation. With the help of the machine, the ends of fractures were made closed up automatically and fixed firmly. From the 1 to 3 year follow up survey for these 6 patients, 5 cases were found to have a complete recovery of their limb functions with the duration for the union being 11 to 17 weeks( 13 on average). Improvement was shown in one case who suffered from the nonunion accompanied with sever knee joint rigidity. The study shows the apparatus fixed on the surface of the femur can help to reduce the damage caused by the stress of bending, spinning or shearing from the ends of fractures. By means of the machine and the dirigation at the early stage, a good result can be also achieved for the close union of fracture and longitudinal stress and the time for bed rest is also reduced greatly.
