Five patients with septic arthritis involving the glenohumeral joint are described. Although initial plain films were normal in all six involved joints, abnormalities were frequent on subsequent examinations, including demineralization (five joints), joint space narrowing (three joints), superior subluxation of the humeral head (three joints), osseous erosion (two joints), and inferior subluxation of the humeral head (one joint). Arthrography was helpful in documenting intraarticular placement of the needle for aspiration, synovial abnormalities, and extraarticular extension of disease. Particularly noteworthy was the occurrence of rotator cuff tears in four of six shoulders, suggesting a possible relationship between joint infection and disruption of the rotator cuff.
本文描述了5例累及盂肱关节的化脓性关节炎患者。虽然最初所有6个受累关节的X线平片均正常，但在随后的检查中异常情况频发，包括骨质脱钙（5个关节）、关节间隙变窄（3个关节）、肱骨头向上半脱位（3个关节）、骨质侵蚀（2个关节）以及肱骨头向下半脱位（1个关节）。关节造影有助于记录穿刺针在关节内的位置、滑膜异常以及疾病的关节外扩展情况。特别值得注意的是，6个肩部中有4个出现了肩袖撕裂，提示关节感染与肩袖损伤之间可能存在关联。
