Greater radial tuberosity size is associated with distal biceps tendon rupture: a quantitative 3-D CT case–control study

Purpose During pronation, the distal biceps tendon and radial tuberosity internally rotate into the radioulnar space, reducing the linear distance between the radius and ulna by approximately 50%. This leaves a small space for the distal biceps tendon to move in and could possibly cause mechanical i...
