We studied 33 patients with calcification in the shoulder region clinically and radiologically. Six cases were male and 27 were female with the age ranged from 32 to 92 years old (average, 61.0±15.1 years old). Four of the cases were bilateral, 17 were right sided and 12 were left sided.According to the symptoms and the physical examinations, all patients were divided into three groups. 21 shoulders of 20 cases were classified as acute group, 12 shoulders of 11 cases as chronic or subacute group, and four shoulders of two cases as asymptomatic group.The patients were evaluated with respect to roentgenographic patterns of calcification according to the following criteria:Type 1; supraspinatus tendon (Seven shoulders).Type 2; characterised by an elevation of the subacromial bursal floor, subbursal rupture or intrabursal rupture (20 shoulders).Type 3; subscapularis tendon (Two shoulders).Type 4; cartilage in the glenohumeral joint (Seven shoulders).Type 5; characteristic large deposition around shoulder region (One shoulder).The clinical diagnosis of the cases in Type 1-3 was calcifying tendinitis, in Type 4 chondrocalcinosis and in Type 5 ectopic calcification associated with brain damage.In acute group, 57% of the cases were treated by needling, 33% by conservative methods and 10% by operative methods. Needling was found more effective as compared to conservative methods. Patients treated by needling with steroid were not as quickly relieved from pain as those without steroid.
