Background: The superficial location of the olecranon bursa places it at high risk for injury, possibly leading to the entry of bacteria into the bursal sac. Early differentiation between septic and nonseptic olecranon bursitis is paramount to direct therapy, to hasten recovery, and to prevent chronic . Methods: Aliterature review was perfonned using MEDLINE files from 1967 to the present. Additional references from the bibliographies of these were also utilized. Results and Conclusions: Olecranon bursitis is a common condition that requires the treating physician to be aware of the predisposing factors, clinical , and laboratory findings of both septic and nonseptic olecranon bursitis. With early recognition, prompt therapy, and preventive measures, the morbidity of septic olecranon bursitis can be considerably reduced, but surgical incision and drainage or excision could be required if conservative therapy fails.
