Management of Mason type 1 radial head fractures: a regional survey and a review of literature.

INTRODUCTION

Despite being the most common fracture around the elbow, the management of Mason type 1 radial head fractures lacks a clear protocol in literature. The aims of this study were to assess our practice of managing this injury and to create guidance for the management of these fractures based on literature review.

METHODS

We designed a survey investigating the practice of orthopaedic surgeons in the management of Mason type 1 fracture. The literature review was carried out looking for the best practice guidelines.

RESULTS

Forty-nine surgeons (out of 56) responded, and mean duration of immobilisation was 11.69 days with the collar and cuff sling as the preferred method. 65.3% offered physiotherapy service to their patients. 20.4% recommended plain radiographic imaging follow-up. Mean duration of follow-up was 43.9 days. Decision to discharge the patient was mostly (77.6%) dependent on clinical improvement at time of last examination. 4.1% of treatment decisions were evidence based.

CONCLUSION

We observed a wide variation in the management of this common injury. Based on the current literature, the best protocol for the management of type 1 radial head fractures should be joint aspiration, followed by immobilisation in a broad arm sling for 2 days. At the first outpatient visit, assessment of the collateral stability should be performed. Patients with stable elbows should be encouraged to stretch these beyond the painful range. Patients can be discharged at this stage with an advice to come back for a clinical and radiographic assessment if there is no improvement at 6 weeks.
