Traumatic olecranon bursitis. Radiologic observations.
The affected elbow of 28 patients with traumatic olecranon bursitis was radiographically compared with the homologous elbow of 28 matched controls. Olecranon spurs, amorphous calcium deposits, or both, were present in 16 patients and 4 controls (p less than 0.01). Air was injected in the bursa in 12 additional patients. Nodules in the bursal floor were noted in 10, and the bursa was partially septated in 8. Olecranon spurs, present in 6 patients, corresponded to the insertion of the triceps tendon. With elbow flexion the bursa flattened and lengthened while the olecranon process glided distally beneath the bursal floor.
