Disorders of the Elbow: Anterior

Introduction

The principal structures of interest in the anterior elbow are the biceps and brachialis tendons. The biceps tendons form from its two muscle bellies and each inserts, close to one another, on the radial tuberosity. The two muscle heads can easily be distinguished from one another but the tendons are grouped close together, although the two components become more separate as the tendon approaches its insertion.

Apart from rupture, the principal pathological processes that affect biceps are tendinopathy, cubital and interosseous bursitis. Tendinopathy of brachialis is rare.
