Drooping shoulder is a roentgenographic abnormality consisting in a discontinuity in the scapulo-humeral arch due to inferior subdislocation of the humeral head. Drooping shoulder is commonly seen in patients with injuries to the shoulder or neurological loss. Two cases of drooping shoulder due to staphylococcal arthritis (after local corticosteroid injections) are reported herein. The mechanism of the downward humeral displacement in septic arthritis is discussed. The other causes of drooping shoulder are reviewed. Precautions needed to avoid increasing the displacement during rehabilitation therapy are outlined.
