Osteoid osteomas are very rare in the elbow region and even more in the bicipital tuberosity of the radius.
Radiographs showed an area of dense mineralization along with surrounding reactive sclerosis at the bicipital tuberosity of the radius (Figure 1).
In some series, osteomas of the upper part of the radius consist 1% to 10% of all of the "elbow cases." To our knowledge, only three cases of osteoid osteoma localized at the bicipital tuberosity of the radius [5, 6] have been reported.
Examination reveals tenderness along the biceps tendon with point tenderness over the bicipital tuberosity of the radius with the forearm fully supinated.
Rupture of the distal biceps tendon from its attachment to the bicipital tuberosity of the radius is relatively common.
In buffaloes (Bos bubalis) the medial collateral ligament is a strong, wide and thick ligament also composed of white fibers and is fixed to a small tuberosity in the medial epicondyle, ending in the medial tuberosity of the radius. Few fibers are fixed at the level of the proximal radio-ulnar interosseous space (Singh & Johari, 1972).
