Smaller Radioulnar Window is Associated with a Distal Biceps Tendon Rupture in patients with limited forearm rotation: a 3D CT Comparison Study of Proximal Impingement Caused by Hypertrophy Radial Tuberosity. A single center case series

It has been suggested that hypertrophy of the radial tuberosity may result in impingements leading to either lesion of the distal biceps tendon or rotational impairment. The two studies on hypertrophy of the radial tuberosity had contradictory results and did not study the distance between the radius and ulna: the radioulnar window. Therefore, this comparative cohort study aims to investigate the radioulnar window in healthy subjects and compare them with subjects suffering from either non-traumatic onset rotational impairment of the forearm or non-traumatic onset distal biceps tendon ruptures with a rotational impairment of the forearm using dynamic 3D CT measurements in order to attain a comprehensive understanding of the underlying etiology of distal biceps tendon ruptures.
