Objective To summarize the experience and lesson of shape memory alloy embracing fixator used for jointed fracture of the Out - third of and Middle - third of the Clavicle. Methods 36 cases with jointed Fractures of the Out - third of and Middle - third of the Clavicle were treated by open reduction,internal fixation with TiNi shape memory allay embracing fixator. Results All the36 cases were followed up for an average of 15 months （ from 8 to 24）, and the average clinical healing was 2.6 months. Evaluated by the method of Han Pingliang＇s criteria, the resules showed that 22 cases obtioned excellent,while 12 cases good and 2 cases ordinary. The excellent and good rae was 94.3%. Conclusion TiNi shape memory alloy embracing fixator can treat jointed Fractures of the Out - third of and Middle - third of the Clavicle effectively with simple and safe operation ,few complications and strong fixation.
