Abstract：Objective To compare the clinical efficacy of open reduction with locking compression plate fixa-tion and closed reduction with external fixator for the treatment of patients with type C radial fractures.Methods Sixty cases of type C radial fractures who were admitted into our hospital from Jan.2010 to Jan.2014 were selected.Thir-ty-four patients were treated by open reduction and locking compression plate fixation(group A),26 patients were treated by closed reduction and external fixation( group B) .The two types of surgery were performed by the same group of doctors.The clinical treatment effect of the two groups were compared.Results There was no statistical difference in the volar tilt angle,ulnar deviation angle and radial height at 3 months after operation between group A and group B(P>0.05).The dorsal extension angle[(40.6 ±8.7)°] and palm flexion angle [(42.7 ±8.9)°]in group A were significantly higher than those of patients in group B at six months after operation(P<0.05).No sta-tistical difference was observed in radial deviation angle,ulnar deviation angle,pronation angle,and rotation angle af-ter operation between the two groups ( P>0.05) .At sixth months after operation,the functional score,range of mo-tion,flexion/extension of group A were significantly better than those in group B(P<0.05).There was no statisti-cal difference in the pain and grip strength between the two groups.The wrist function of group A was significantly better than that of group B ( P<0.05 ) . Conclusion Open reduction with locking compression plate fixation is more conducive to the recovery of wrist joint function than closed reduction and external fixation in the treatment of patients with type C fracture of radius.
