Magnetic resonance imaging findings in 46 elbows with a radial head fracture

Abstract

Background and purpose Radial head fractures are common and may be associated with other injuries of clinical importance. We present the results of a standard additional MRI scan for patients with a radial head fracture. Patients and methods 44 patients (mean age 47 years) with 46 radial head fractures underwent MRI.17 elbows had a Mason type-I fracture 23 a Mason type-II fracture and 6 elbows had a Mason type-III fracture. Results Associated injuries were found in 35 elbows: 28 elbows had a lateral collateral ligament lesion 18 had capitellar injury 1 had a coronoid fracture and 1 elbow had medial collateral ligament injury. Interpretation The incidence of associated injuries with radial head fractures found with MRI was high. The clinical relevance should be investigated. Copyright: © 2010 Nordic Orthopedic Federation.
