脊髓灰质炎后遗畸形膝关节的X线运动学分析

A DYNAMICANALYSIS OF KNEE JOINTS WITH POSTPOLIOMYELITIC DEFORMITY

观察了３００例脊髓灰质炎后遗畸形膝形关节Ｘ线平片。对其中２Ｏ例患者膝关节与２０倒正常人膝关节进行了运动学对比分析。对畸形膝关节股胫骨的分离式运动，压迫式运动和异常滚动三种运动方式的成固和后果的分析结果表明：三种异常的运动方式是造成股胫关节面畸形的直接动困。运用Ｘ线摄影方法对膝关节进行运动学分析能提供Ｘ线平片所不能表达的诊断信息，这对脊髓灰质炎后遗膝关节畸形及一般膝关节运动性疾患的术前疹断及术后疗效对比都有实际意义。

Three hundred X-ray films of knee joints with postpoliomyelitic deformity have been obberved。Twenty normal knee joints were compared with postoliomyclilic deformity,and kinematics wereanalysed with X-ray camera。 Three kinds of motion of femurtibia joint i.e,the motioncompressing on tibial,the motion leaving from tibial and the abnonnal rolling on tibial,werestated。 Their Causes and Consequenas were also discussed,It was suggested that the abnormalmotion were the direct cauase.of deformity of knee joint.The Dynamic analysis with X raycamera was much better than X ray film for diagnosis.it is important for the diagnosis of kneejoint with poltpoliomyelitic deformith,trauma or degeneration,also,good for analysis of theirtherapeutic effects。
