Bursae are fluid filled structures between mobile parts of the musculoskeletal system to reduce friction by lubrication. Repeated trauma to bursae results in bursitis which are usually aseptic initially, which may be followed by infection. Many cases are related to occupational or recreational activities. We present an analysis of cases of Staphylococcus aureus septic bursitis admitted to 10 hospitals over a 3-year period. The olecranon bursa was the most common site involved 42/65 (64.6%) followed by prepatellar bursa 17/65 (26.1%). The mean age was 61.2 years. Fifty five out of Sixty-five (84.6%) were male. The majority were caused by methicillin susceptible Staphylococcus aureus 52/65 (80%). The occupational history was missing for most patients. The occupations reported in few of the patient charts were floor worker, construction worker and roofer. Sixty one out of sixty-five (92.4%) of cases involved the elbow and knee. Avoidance of activities that result in repeated friction or trauma to elbows and knees would prevent majority of cases of septic bursitis.
