Nickel-titanium Shape Memory Alloy Embracing Fixator for the Treatment of Mid-clavicle Comminuted Fracture

Objective] To explore the clinical effect of nickel-titanium shape memory alloy embracing fixator for the treatment of mid-clavicle comminuted fracture. Methods] A total of 168 patients with mid-clavicle comminuted fracture were treated with nickel-titanium shape memory alloy embracing fixator. Results] There was no wound infection, nonunion and foreign body reaction. The 146 cases were followed up for 3 to 34 months. According to Neer rating criteria, 119 cases were excellent and 22 cases were good. The excellence and good rated was 96.6%. The embracing fixator after operationwas cinched in 4 cases which 2 cases were replaced. The embracing fixator was broken in one case which was healed after the replacement of steel fixation. Conclusion] Nickel-titanium shape memory alloy embracing fixator for the treatment of mid-clavicle comminuted fracture is easy to operate and has stable fixation and good biocompatibility. It is in favor of the early functional exercise after surgery.
