To compare the effect of Operative Plate Fixation Versus Replacement for Mason Type III Fracture of Radial Head

From April 2015 to October 2016, patients with comminuted radial head fractures diagnosed as Mason type III are retrospectively included in this study, they were treated with either operative plate or radial head replacement. All the patients are regularly followed up in clinic. Then we will compare the union rate and clinical functional outcome(Mayo score) between the 2 groups at 1 year after surgery.

Inclusion Criteria:

Men or women aged 18 to 65 years of age with Mason Type III radial head fracture are confirmed by radiograph within 1 month post injury Provision of informed consent

Exclusion Criteria:

Pathological fractures Non-displaced (cortical contact) fractures Open fractures Presence of vascular or nerve injury Fractures more than 1 month post-injury Limited life expectancy due to significant medical co-morbidity Medical contraindication to surgery Inability to comply with rehabilitation or form completion Likely problems, in the judgement of the investigators, with maintaining follow-up (i.e. patients with no fixed address, patients not mentally competent to give consent, etc.)
