Analysis of Radial Head Implant Length with Use of Contralateral Elbow Radiographs

INTRODUCTION: This article describes a technique in which measurements are obtained from radiographs of the contralateral, normal elbow to predict the magnitude of overlengthening resulting from use of a metallic radial head prosthesis. STEP 1 OBTAIN BILATERAL ELBOW RADIOGRAPHS: Obtain bilateral digital anteroposterior radiographs of the elbows that are orthogonal to the forearm in 45° of flexion and neutral forearm rotation.
