Open Reduction and Internal Fixation with Herbert Screws for Mason Type m Radial Head Fractures

Objective To evaluate the clinical effect of Herbert screws internal fixation of the Mason type Ⅲ radial head fractures.Method 18 radial head fracture patients with Mason type Ⅲ were treated by open reduction and Herbert screw internal fixation.Results 18 cases were followed up for 21 months averagely(ranged from 12 to 36 months).All fractures healed well in 4 to 10 months after operation.No elbow instability or weakness occurred.The mean Mayo Elbow Performance Index score was 88.6±11.4,the results showed excellence in 12 and good in 6.The flexion range of the elbow was 7° to 135°,with 80° pronation and 72° supination averagely.Conclusion Internal fixation of Herbert screws can achieve satisfactory effect for Mason type Ⅲ radial head fracture with advantages as rigid internal fixation and early function exercises,but the indication should be strictly selected.
