Arthroplasty Complications, Elbow Fracture, Radial Head Fracture

Brief summary

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.

Interventions

PROCEDUREType of radial head arthroplasty

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.

Design outcomes

Primary

Measure	Time frame	Description
QuickDASH	2-16 years postoperatively	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).

Secondary

Measure	Time frame	Description
Pain	2-16 years postoperatively	Visual analogue scale. Range 0-10. Higher value indicate more intensive pain.
Range of motion	2-16 years postoperatively	Rang of elbow motion. Measured in grades. Supination, pronation, extension and flexion were measured.
Reoperation	2-16 years postoperatively	Number of patients needing revision surgery
Radiographic evaluation	2-16 years postoperatively	Radiographic evaluation of the prosthesis. The presence of radiolucent lines, loosening of the prosthesis.
