We analyzed the incidence and cause of glenohumeral osteoarthritis including its early stage with plain radiographs. In Kishiwada City Hospital we treated 4035 patients with orthopaedic complications in 1995. A total of 345 patients (390 shoulders) had shoulder diseases. The patients with primary glenohumeral osteoarthritis were 2 men and 14 women (18 shoulders) aged 60 to 86 years (mean 71.9 years), and 2 cases were secondary osteoarthritis. In 2 cases (3 shoulders) of severe osteoarthritis other joints were also affected. Only 4 (25%) of the patients with primary glenohumeral osteoarthritis had osteoarthritic changes only in the glenohumeral joint. The incidence of primary glenohumeral osteoarthritis was 0.4% in the patients with orthopaedic complications and 4.6% in the patients who had shoulder diseases. Women were more likely to have primary glenohumeral osteoarthritis than men, and patients older than 60 years of age were more likely to have it than younger patients.
我们通过X线平片分析了包括早期阶段在内的盂肱关节骨关节炎的发病率及病因。1995年，岸和田市立医院共收治了4035例骨科并发症患者。其中共有345例（390个肩部）患有肩部疾病。原发性盂肱关节骨关节炎患者中，男性2例，女性14例（18个肩部），年龄在60至86岁之间（平均71.9岁），继发性骨关节炎2例。在2例（3个肩部）严重骨关节炎患者中，其他关节也受到影响。原发性盂肱关节骨关节炎患者中只有4例（25%）仅在盂肱关节出现骨关节炎改变。原发性盂肱关节骨关节炎在骨科并发症患者中的发病率为0.4%，在肩部疾病患者中的发病率为4.6%。女性比男性更易患原发性盂肱关节骨关节炎，60岁以上患者比年轻患者更易患病。
