Methods:A total of twenty patients with eighteen males and two females was studied. There were three patients with fractares in the upper one third of thighbone, five with fractures in the middle part of thighbone, six with humeral fractures, three with collarbone fractures,one with ulna fracture and two with thighbone fractures as complication of artificial hipbone arthroplasty. After exposure and fixation of fracture ends, prepared encircled fixer was inserted into 0～4℃ normal reline(NS) to lower its temperature, then pulled out with a clamp. Encircled fixer was put on the tersile side of the fractured bone(center pointed to fracture line), restored and stabilized after raising temperature in 40℃ NS. Results: Encircled fixers of shape memory alloy were used to treat twenty patients with bone fracture.Clinical concrescence was obtained in 1.5 to 3 months after operation,and the joint gained its normal function without complication. Conclusion:Encircled fixer of shape memory alloy has features as exerting vertical pressure continoulsy, little stress shield effect and convenient manipulation, especially adapt to stem fracture after artificial arthroplasty.展开更多
