ARTHROSCOPIC SURGERY OF HIP JOINTS IN CHILDREN

为了给儿童髋关节镜手术提供明确、安全的方法，进行了临床和实验研究。通过关节镜下观察髋关节的解剖结构，选择合适的髋关节镜观察点。猴的髋关节作为儿童髋关节的模型具有一定的研究价值。猴子的臀部只有和人类髋部一样的下唇。用激光血流仪测量牵引状态下股骨头的血流量，观察股骨头的血流量。内旋位的血流量不受牵引力的影响，但减少。后入路视野较前入路宽。通过前入路观察髋臼的Linbus。将猴实验性髋关节脱位模拟为先天性髋关节脱位，进行髋关节镜手术。髋关节镜已应用于儿童髋关节疾病。通过对儿童髋关节镜检查，可以解决先天性髋关节脱位、Perths病和SCFE的病因。

In attempt to provide definite and safety method of the arthroscopic surgery for the hip joints in children, the bacic and experimental study was performed. Anatomy ofthe hip joint through the arthroscopic view was investigated and then the proper vidual points for hip arthroscopy were selected. The hip joint of monkey was useful tostudy as a model of children's hip. Monkey's hip only has labrum as same as human hip. Blood flow in the femoral head was measured by laser flowretry under traction and in position of lower extremity. Blood flow was not effected by the traction forcebut decreased in the internal-rotated position. Visual range by posterior approach was wider then byanterior approach. Linbus of the acetablum was observed totally by anterior approach. Experimental dislocation of the Monkey's hip was simulated as congenital dislocation of the hip joint, and triedto operate hip arthroscopic surgery. Hip arthroscopy has been applied for hip diseases in children. It will be possible to resolve the pathgenesis of congenital dislocation of hip joint, Perthes' disease and SCFE by arthroscopic findings of children's hip.
