Fractures of the radial head are among the most common fractures in the elbow and represent one-third of all elbow fractures.This retrospective cohort study was performed between 2004 and 2014 at Sundsvall and Umeå University hospital, Sweden. All patients who were operated on between 2004 and 2014 with a radial head arthroplasty for an acute or sequelae due to a caput radii fracture.The aim of this study is to evaluate clinical or radiological differences between patients treated with a unipolar or bipolar radial head arthroplasty.

| Type of radial head arthroplasty | Procedure | Patiens are either treated with a unipolar or a bipolar radial head arthroplasty. At Sundsvall hospital all patients were treated with a unipolar and at Umeå university hospital all patients were treated with a bipolar arthroplasty. |
| Measure | Description | Time Frame |
|---|---|---|
| QuickDASH | Patients reported outcome measure. An abbreviated version of the Disabilities the Arm, Shoulder and Hand (DASH) questionnaire. Higher score indicate a greater level of disability, lower scores indicate a lower level of disability. The score ranges from 0 (no disability) to 100 (most severe disability). | 2-16 years postoperatively |
| Measure | Description | Time Frame |
|---|---|---|
| Pain | Visual analogue scale. Range 0-10. Higher value indicate more intensive pain. | 2-16 years postoperatively |
| Range of motion | Rang of elbow motion. Measured in grades. Supination, pronation, extension and flexion were measured. |
