Introduction Frozen shoulder is a common disorder involving scapulohumeral pain and loss of motion with gradual onset. Previous studies have demonstrated that thickened coracohumeral ligament is a diagnostic tool but when coracohumeral ligament is thickened is unknown. The aim of this study was to evaluate that coracohumeral ligament thickness in freezing phase of frozen shoulder and effect of intra articular injection on the coracohumeral ligament.
Methods This study reviewed 10 patient with frozen shoulder in freezing phase, retrospectively. The inclusion criteria were: (1) unilateral shoulder pain with duration of than 9 months (2) loss of 30º or more in passive range of motion in the glenohumeral joint in external rotation and at least one of flexion, abduction, or internal rotation. All patient received sonographic-guided corticosteroid and lidocaine injection into the intra-articular space using 20 mg triamcinolone. And coracohumeral thickness is measured by sonography (Figure 1) and was compared among 3 group. (baseline, follow up and unaffected); Baseline: affected side and before IA injection, Follow up: affected side and After IA injection 3weeks and Unaffected: unaffected side and before IA injection
Results The coracohumeral ligament of patient on the affected side was thickened (12.0±3.4mm), compared to that of patient on the unaffected side (8.8±2.7mm). Follow up coracohumeral ligament thickness was 10.3±1.8mm without significance. (Table 1)
Conclusion Our data suggest that the coracohumeral ligament in the freezing phase of frozen shoulder is not thickened as 3mm but thickened compared to unaffected side and IA injection may prohibit the thickening of coracohumeral ligament with improving symptoms.
