Osteochondroma associated with complete rupture of the distal biceps tendon: case report.

Osteochondromas are the most common benign bone tumors. However, osteochondromas rarely involve the proximal radius. We present the case of a solitary osteochondroma that occurred in a critical area of the proximal radius near the insertion of the biceps tendon and ultimately led to rupture of the tendon. The lesion was confirmed histologically and resected, followed by successful repair of the distal biceps tendon using a suture anchor.
