The prevalence of rotator cuff tears increases with age and several studies have shown that diabetes is associated with symptomatic shoulder pathologies. Aim of our research was to evaluate the prevalence of shoulder lesions in a population of asymptomatic elderly subjects, normal and with non insulin - dependent diabetes mellitus.
The study was performed on 48 subjects with diabetes and 32 controls (mean age: 71.5 ± 4.8 and 70.7 ± 4.5, respectively), who did not complain shoulder pain or dysfunction. An ultrasound examination was performed on both shoulders according to a standard protocol, utilizing multiplanar scans.
Tendons thickness was greater in diabetics than in controls (Supraspinatus Tendon: 6.2 ± 0.09 mm vs 5.2 ± 0.7 mm, p < 0.001; Biceps Tendon: 4 ± 0.8 mm vs 3.2 ± 0.4 mm, p < 0.001). Sonographic appearances of degenerative features in the rotator cuff and biceps were more frequently observed in diabetics (Supraspinatus Tendon: 42.7% vs 20.3%, p < 0.003; Biceps Tendon: 27% vs 7.8%, p < 0.002).Subjects with diabetes exhibited more tears in the Supraspinatus Tendon (Minor tears: 15 (15.8%) vs 2 (3.1%), p < 0.03; Major tears: 15 (15.8%) vs 5 (7.8%), p = ns), but not in the long head of Biceps. More effusions in subacromial bursa were observed in diabetics (23.9% vs 10.9%, p < 0.03) as well as tenosynovitis in biceps tendon (33.3% vs 10.9%, p < 0.001).In both groups, pathological findings were prevalent on the dominant side, but no difference related to duration of diabetes was found.
Our results suggest that age - related rotator cuff tendon degenerative changes are more common in diabetics.Ultrasound is an useful tool for discovering in pre - symptomatic stages the subjects that may undergo shoulder symptomatic pathologies.
肩袖撕裂的患病率随着年龄的增长而增加，多项研究表明糖尿病与有症状的肩部病变有关。我们研究的目的是评估无症状老年人群中肩袖病变的患病率，包括正常人和非胰岛素依赖型糖尿病患者。
本研究纳入了 48 例糖尿病患者和 32 例对照者（平均年龄：71.5 ± 4.8 岁和 70.7 ± 4.5 岁），他们均无肩部疼痛或功能障碍。对所有研究对象双侧肩关节进行超声检查，采用多平面扫描。
糖尿病患者的肌腱厚度大于对照组（冈上肌腱：6.2 ± 0.09 毫米比 5.2 ± 0.7 毫米，p < 0.001；二头肌肌腱：4 ± 0.8 毫米比 3.2 ± 0.4 毫米，p < 0.001）。糖尿病患者的肩袖和二头肌的退行性改变更为常见（冈上肌腱：42.7%比 20.3%，p < 0.003；二头肌肌腱：27%比 7.8%，p < 0.002）。糖尿病患者的冈上肌腱撕裂更为常见（小撕裂：15 例（15.8%）比 2 例（3.1%），p < 0.03；大撕裂：15 例（15.8%）比 5 例（7.8%），p = 无统计学意义），但长头型二头肌肌腱撕裂并不常见。糖尿病患者的肩峰下囊积液更为常见（23.9%比 10.9%，p < 0.03），二头肌肌腱腱鞘炎也更为常见（33.3%比 10.9%，p < 0.001）。两组患者的病变均以优势侧多见，但与糖尿病病程无相关性。
本研究结果提示，年龄相关的肩袖肌腱退行性改变在糖尿病患者中更为常见。超声检查是一种有用的工具，可以在无症状阶段发现可能出现肩部症状性病变的患者。
