A clinical followup study was performed of joint side tears of the rotator cuff to define the pathogenic mechanisms and factors that affect their evolution. From 1982 to 1992, the authors treated 61 joint side tears, diagnosed by arthrography. Among them, 40 tears were follow-up during conservative treatment. Arthrographies were repeated at a mean of 412 days. There were 16 male and 20 female patients, with a mean age of 61 years. Two male and two female patients had bilateral tears. The average shoulder assessment score according to the Japanese Orthopaedic Association rating at the initial visit to the hospital was 68 points, and 80 points at followup time. Followup arthrographies revealed disappearance of the torn portion in four instances, reduction of the tear size in four, enlargement of the tear size in 21, and progress to full thickness cuff tear in 11 patients. Prognosis of the joint side tear appears to be worse with increasing age, larger tear size, and absence of history of trauma.
对肩袖关节侧撕裂进行了一项临床随访研究，以确定影响其演变的致病机制和因素。1982年至1992年，作者治疗了61例经关节造影诊断的关节侧撕裂。其中，40例撕裂在保守治疗期间进行了随访。关节造影平均在412天重复进行。有16例男性和20例女性患者，平均年龄61岁。2例男性和2例女性患者有双侧撕裂。根据日本骨科协会评分，初诊时平均肩部评估得分为68分，随访时为80分。随访关节造影显示，4例撕裂部分消失，4例撕裂尺寸减小，21例撕裂尺寸增大，11例患者进展为全层肩袖撕裂。关节侧撕裂的预后似乎随着年龄的增加、撕裂尺寸的增大和无创伤史而更差。
