Objective

Determine the demographic and clinical factors that predict infraspinatus muscle degeneration in individuals with an isolated supraspinatus tendon tear.

Materials and methods

A retrospective analysis was performed using the medical records of patients who had a shoulder MRI interpreted by 1 of 3 fellowship-trained musculoskeletal radiologists since the implementation of a standardized MRI 3 T protocol within our healthcare system. Demographic (e.g., age, sex) and clinical data (e.g., tear size, muscle degeneration, co-morbidities) were collected. Patients with an isolated supraspinatus tendon tear (n = 121) were assigned to one of two groups based on whether any infraspinatus muscle degeneration was present. Logistic regression was used to assess the univariate relationships between infraspinatus muscle degeneration and patient and clinical data, while least absolute shrinkage and selector operator (LASSO) logistic regression was used to assess the multivariable relationship.

Results

Of the patients with an isolated supraspinatus tendon tear, 16.5% had evidence of infraspinatus muscle degeneration. The presence of infraspinatus muscle degeneration was independently associated with cardiovascular disease (P = 0.01), supraspinatus muscle degeneration (P < 0.01), and subscapularis muscle degeneration (P = 0.01). When the multivariable relationship is assessed, supraspinatus muscle degeneration emerged as the only variable of significant importance for detecting infraspinatus muscle degeneration (specificity: 87.1%, sensitivity: 80.0%).

Conclusion

Infraspinatus muscle degeneration is not uncommon in individuals with an isolated supraspinatus tear and is most associated with concomitant supraspinatus muscle degeneration. These findings highlight the need for clinicians to specifically assess the status of each rotator cuff muscle, even when the tendon itself is intact.

孤立性冈上肌腱撕裂个体冈下肌退化的预测因子

客观的

确定预测孤立性冈上肌腱撕裂个体冈下肌变性的人口统计学和临床因素。

材料和方法

自我们的医疗保健系统内实施标准化 MRI 3 T 方案以来，我们使用患者的医疗记录进行了回顾性分析，这些患者的肩部 MRI 由 3 名经过专科培训的肌肉骨骼放射科医生中的 1 名进行解释。收集人口统计数据（例如年龄、性别）和临床数据（例如撕裂大小、肌肉退化、合并症）。孤立性冈上肌腱撕裂的患者（ n = 121）根据是否存在冈下肌变性被分配到两组中的一组。使用逻辑回归来评估冈下肌变性与患者和临床数据之间的单变量关系，而使用最小绝对收缩和选择算子（LASSO）逻辑回归来评估多变量关系。

结果

在孤立性冈上肌腱撕裂的患者中，16.5% 有冈下肌退变的证据。冈下肌变性的存在与心血管疾病（ P =0.01）、冈上肌变性（ P <0.01）和肩胛下肌变性（ P =0.01）独立相关。当评估多变量关系时，冈上肌变性成为检测冈下肌变性具有重要意义的唯一变量（特异性：87.1%，敏感性：80.0%）。
