Effect Analysis of Internal Fixation for Radial Head Fractures with Type Mason II-IV

Objective To investigate the clinical efficacy of internal fixation of radial head fractures with type Mason Ⅱ to Ⅳ.Methods A total of 41 radial head fracture cases with type Mason Ⅱ to Ⅳ admitted from March 2002 to June 2012 were treated,including 18 cases of type Ⅱ,17 cases of type Ⅲ and 6 cases of type Ⅳ according to Mason typing.Open fracture was found in 2 cases,with type Ⅱ and type ⅢA for each according to Gustilo typing.Multiple fractures were combined in 9 cases.The duration of injury to operation was 3 hours to 30 days with an average of 6.7 days.The internal fixation was Kirschner wire fixation in 8 cases,screw fixation in 11 cases,micro-plate fixation in 15 cases and absorbable screws fixation in 7 cases.Results All 41 patients were followed up for 4 to 28 months with an average of 10 months.All fractures achieved healing.According to the Broberg and Morrey elbow score judgment,the outcome was revealed excellent in 22 cases,good in 12 cases,fair in 4 cases and poor in 3 cases,and the fineness rate was 82.9%(34/41).Kirschner needle slipping to subcutaneous was found in 2 children and taken out after fracture healing.Conclusions The surgical intervention of internal fixation can improve the prognosis of elbow function for radial head fracture patients with type Mason Ⅱ to Ⅳ.The specific measures of fracture anatomic reduction,firmly fixed effects,good stability of joint repair and early functional exercise can help patients get good effect.
