Lameness associated with the bicipital bursa in an Arab stallion

Severe, chronic lameness in the, left forelimb of a five-year-old Arab stal lion was localised to the bicipital bursa by local anaesthesia and gamma sc intigraphy. Radiographic and ultrasonographic examinations of the proximal humeral tubercles and bicipital bursa revealed new bone production in the r egion of the intertubercular grooves and irregularities in the density of t he, soft tissues of the bicipital tendon and bursa. An endoscopic examinati on of the bicipital bursa with a standard arthroscope under general anaesth esia was a useful diagnostic procedure. The stallion was euthanased, and ma rked fibrocartilage fibrillation and formation of adhesions were found post mortem, confirming a diagnosis of chronic fibrinous bursitis.
