Cubital Bursa

Several synovial bursae around the elbow joint lessen friction between bones and the overlying skin and soft-tissue structures. The most important are the olecranon bursa and the bidpitoradial bursa. The olecranon bursa is a large subcutaneous bursa which intervenes between the skin and the olecranon process over the posterior aspect of the elbow. The bidpitoradial bursa (cubital bursa) lies deep in the anterior compartment of the elbow, between the distal biceps tendon and the radial tuberosity, to reduce friction between, especially during pronation of the forearm (Skaf et al. 1999). In fact, the radial tuberosity rotates posteriorly during pronation and wraps the tendon around the radial cortex. During this movement, the bursa is tracked between the tendon and the bone (Fig. 8.8). When distended by fluid, the bicipitoradial bursa may surround the biceps tendon completely and may cause a mass effect on the adjacent branches of the radial nerve. 

The distal biceps tendon is not invested by a synovial sheath but it is covered by aparatenon. Justproximal to the tendon insertion, it is in contact with the bicipitora-dial (cubital) bursa. This bursa is located between the...
