Mid-shaft humeral fractures in adults are common these days and often present with a management dilemma between operative and non-operative treatment. This study evaluates the outcome of such fractures treated non-operatively over a span of 10 years.

In this retrospective study, a review of case notes and radiographs of patients whose mid-shaft humerus fractures were treated non-operatively between 1994 and 2004 was done. Those younger than 16 years and/or who had surgery primarily were excluded. Various factors including patient demographics, mechanism of injury, AO fracture classification and time to union were studied. Mean patient follow-up was 4 years and 6 months. The Oxford shoulder score was used for functional assessment.

There was a total of 43 patients, mostly men with involvement of the dominant arm. 5 patients required open reduction and internal fixation with bone grafting for non-union. The average Oxford shoulder score was 18. The majority of patients could resume their jobs and the average time to union was 9 weeks.

We conclude from this study that there is a high union rate in the mid-shaft humeral fractures in adults treated non-operatively, with an acceptable functional outcome.
