项目摘要

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.

为给儿童髋关节镜手术提供一种确切、安全的方法，进行了基础和实验研究。通过对髋关节镜下解剖的观察，选择合适的髋关节镜观察点。猴髋关节可作为儿童髋关节的模型。猴子的髋关节和人类的一样只有盂唇。采用激光血流仪测量牵引状态下和下肢体位下股骨头内的血流量。血流量不受牵引力的影响，但在内旋位减少。后入路的视野较前入路宽。采用前入路，完整观察髋臼连线。模拟猴髋关节先天性脱位，尝试髋关节镜手术。髋关节镜已应用于儿童髋关节疾病。儿童髋关节镜下所见将有助于解决先天性髋关节脱位、Perthes病和SCFE的病因。
