Enthesophyte on the radius: a case report

Abstract

Introduction Radius is a lateral bone of the fore- arm. The upper end of the radius consists of head, neck and radial tuberosity. Tendon of the biceps bra- chi muscle is inserted into the poste- rior rough part of radial tuberosity. The anterior smooth part of radial tuberosity is separated from the posterior part by bursa. In this case, bony projection from the posterior rough part of radial tuberosity was observed. Case report During examination of radii in the osteology lab of King George's Medi- cal University, three radii (two radii of left hands and one of right hand) out of 100 assorted radii were observed having longitudinal and trans- verse enthesophytes. The lengths, heights and thicknesses of these longitudinal enthesophytes in the left two radii were 2.2/0.7/0.2 cm, 1.9/0.7/0.4 cm and 2.2/0.6/0.4 cm in one right radius. The lengths, heights and thicknesses of these transverse enthesophytes in the left two radii were 1.1/0.3/0.2 cm, 0.8/0.2/0.2 cm and 0.7/0.1/0.1 cm in one right radius. Discussion Enthesophytes may be formed due to overuse of the biceps brachi muscle. This extra bony growth may impinge on the surrounding structures lead- ing to neurovascular complications and restriction of biomechanical movements of forearm.
