Open Reduction and Micro-plate Internal Fixation for Complex Radial Head Fractures

Objective To investigate the feasibility and effect of micro-plate internal fixation of complex radial head fractures.Method Twenty-one patients with radius head fractures were treated by open reduction and micro-plate internal fixation,including type Ⅱ in 14 cases and type Ⅲ in 7 cases according Mason classification.Results The operation time ranged 50 to 80 minutes with an average of(65±15) minutes.All cases were followed up for 14.5 months(ranged from 5 to 24 months).All fractures obtained bone union in 3 to 5 months after the operation.The range of flexion,stretch,pronation and supination of the elbow joints was 110°~125°(mean,115°),0°~10°(mean,5°),50°~60°(mean,55°)and 40°~60°(mean,50°) respectively.There was no elbow valgus and traumatic arthritis.One case complicated with mild elbow pain.According to Broberg and Morrey criteria,the surgical outcomes were excellent in 8 cases,good in 10 cases,fair in 3 cases,and the fineness rate was 85.7%.Conclusion Open reduction and micro-plate internal fixation of complex radial head fracture can provide an anatomical reduction,stable fixation and early range of motion.
