INDICATORS OF FUNCTIONAL OUTCOME FOLLOWING ISOLATED PROXIMAL RADIAL FRACTURES

Abstract

The purpose of this prospective study was to determine the predictive factors and hence optimal management of closed uncomplicated proximal radial fractures. We examined all patients presenting to our unit over an 18-month period with isolated closed proximal radial fractures. 237 consecutive patients were included. Demographic data, physical examination, radiographs, treatment and complications were recorded. Patients were reviewed at 2, 6, 12, 26 and 52 weeks post injury. Outcome was determined via functional assessment and Mayo Elbow Score (MES). Data were analysed using SPSS.

There were 156 (66%) radial head fractures and 81 (34%) radial neck fractures. 225 (95%) patients were treated non-operatively in a collar and cuff for one week followed by physiotherapy. 12 (5%) patients required primary surgical intervention due to either a mechanical block to forearm rotation (n=4) or a significant degree of radiographic comminution and/or displacement (n=8). Of the 201 patients who attended follow-up, 183 (91%) patients achieved excellent or good functional results measured on the MES. 155 (78%) patients achieved this by six weeks, with an average flexion arc of 125 degrees. Of the 12 patients treated operatively, the average MES at six weeks was fair (60). Regression analysis showed that increasing age, the AO-OTA fracture classification (B2.3, C2.3), radiographic displacement and operative treatment were significant predictors of a fair or poor outcome at six weeks.

The majority of isolated proximal radial fractures can be treated non-operatively with early mobilization, achieving excellent or good results within 6 weeks. Age, fracture classification, radiographic displacement and treatment choice are important factors that determine speed of recovery.
