This retrospective study investigated the association between clinical features and MRI findings in patients with early adhesive capsulitis of the shoulder.
The study included 29 patients with early adhesive capsulitis of the shoulder. The clinical diagnostic criteria were significantly restricted passive range of motion (ROM) and a symptom duration of up to 9 months. Various measurements related to adhesive capsulitis, including humeral and glenoid capsular thickness in the axillary recess, maximal axillary capsular thickness, coracohumeral ligament thickness, and anterior capsular thickness were measured on MRI. Abnormal humeral and glenoid capsular hyperintensity in the axillary recess, abnormal hyperintensity in the rotator interval, and obliteration of the subcoracoid fat triangle were also evaluated. Correlations between MRI findings and clinical features, including limited ROM, pain, and symptom duration were sought.
Maximal axillary and humeral capsular thickness measured on MRI were negatively correlated with ROM for internal rotation. Also, hyperintensity in axillary recess and glenoid capule were correlated with ROM for abduction. Humeral capsular hyperintensity was correlated with ROM for forward flexion. There were no MRI findings that showed correlations with ROM for external rotation and severity of pain. The hyperintensity in the humeral capsule among MRI findings was only correlated with duration of symptoms.
MRI can be useful for assessment of several measures of clinical impairment in patients with adhesive capsulitis. Thickening and hyperintensity of the joint capsule in the axillary recess on MRI is associated with limited ROM and duration of symptoms.
本回顾性研究调查了早期粘连性肩关节囊炎患者的临床特征与MRI表现之间的关联。
该研究纳入了29例早期粘连性肩关节囊炎患者。临床诊断标准为被动活动范围（ROM）明显受限且症状持续时间长达9个月。在MRI上测量了与粘连性肩关节囊炎相关的各种指标，包括腋窝隐窝处肱骨和肩胛盂关节囊厚度、腋窝关节囊最大厚度、喙肱韧带厚度和前方关节囊厚度。还评估了腋窝隐窝处肱骨和肩胛盂关节囊异常高信号、旋转间隙异常高信号以及喙突下脂肪三角消失情况。研究了MRI表现与临床特征（包括ROM受限、疼痛和症状持续时间）之间的相关性。
MRI测量的腋窝关节囊最大厚度和肱骨关节囊厚度与内旋ROM呈负相关。此外，腋窝隐窝和肩胛盂关节囊的高信号与外展ROM相关。肱骨关节囊高信号与前屈ROM相关。没有MRI表现显示与外旋ROM和疼痛严重程度相关。MRI表现中肱骨关节囊的高信号仅与症状持续时间相关。
MRI有助于评估粘连性肩关节囊炎患者的多种临床损伤指标。MRI上腋窝隐窝处关节囊增厚和高信号与ROM受限和症状持续时间相关。
