Right proximal forearm. a Superficial dissection. A tumour has caused lateral displacement of the brachioradialis muscle (a). The radial nerve (c) has been diverted over the superior surface of radial head (b). b Deep dissection. Exostosis in the region of the radial tuberosity (a), radial head dislocation (b). The capitulum (c) formed an articulation with the radius at the radial tuberosity (a), causing the biceps brachii tendon (d) to be incorporated into the joint. c DESS MRI of proximal radius. An osteochondroma present at the radial tuberosity (a) has a continuous cortex and medulla with the underlying bone. A cartilage cap is present on the surface (b). Note the low signal within the head of the radius (c). d Sagittal section of radial head. Radius displays a large void (a) within the epiphysis
