摘　　要：收集深圳市观澜人民医院1998-03/2005-12进行人工全髋关节置换的63例患者的资料,对其进行回顾性分析,发现置换后3～10d内有3例发生人工全髋关节脱位,发生率为4.8%。分析其脱位原因,分别为术后活动过度,肌肉松弛,髋臼位置不良和大转子骨折。其中1例X射线拍片假体位置良好的患者在全麻下作充分手法牵引和复位成功后返回病房作下肢外展位皮牵引3周;第2例股骨骨折致假体松动即作切开复位和钢丝内固定;第3例髋臼前倾角度过小者则需重置髋臼假体位置。提示置换后髋关节活动幅度过大、大转子骨折致假体柄松动、髋臼假体位置不良是人工全髋关节置换后发生髋关节早期脱位的常见原因,正确处理有利于预防人工全髋关节置换后髋关节脱位。Data of 63 patients undergoing total hip arthroplasty （THA） in Guanlan People＇s Hospital between March 1998 and December 2005 were retrospectively analyzed. Three patients （4.8%） developed dislocation 3 to 10 days after THA, caused by over extent of hip-joint motion, muscle relaxation, acetabulum cacothesis and great trochanter fracture. The first patient was treated with manipulative reduction after anesthesia; the second was treated by operative reduction to fix the bone fracture and prosthesis; the acetabular prosthesis of the third was reset. The results indicate that over extent of hip-joint motion and great trochanter fracture can lead to prosthesis handle loosening, and acetabulum cacothesis is common cause for early dislocation after THA. Correct treatment of these causes is beneficial to prevent the dislocation after THA.
