Tóm tắt

ObjectivesTo study the shear wave elastography (SWE) of the coracohumeral ligament (CHL) in different stages of frozen shoulder and to analyze its correlation with the visual analogue scale (VAS) score and shoulder range of motion (ROM).MethodsSixty‐four patients with frozen shoulder were divided into three stages: stage I (freezing phase), stage II (frozen phase), and stage III (thawing phase). The SWE of the CHL of the affected and healthy sides was measured and compared in the different stages. The VAS score and ROM of the affected side were evaluated, and their correlation with the SWE of the CHL was analyzed in the different stages.ResultsIn stage I frozen shoulder, the SWE of the CHL on the affected side was lower than that on the healthy side, while in stages II and III, the SWE on the affected side was higher (P = .001 for all). The SWE of the CHL of the affected side was different across the three stages; the SWE in stages II and III higher than that in stage I (P < .01), while the difference between stages II and III was not significant (P > .05). The SWE of the CHL of the affected side was negatively correlated with the VAS score but not with forward flexion (Ff), external rotation (Er) or internal rotation (Ir) in stage I; in stages II and III, it was positively correlated with the VAS score and negatively correlated with Ff, Er, and Ir.ConclusionsThe CHL stiffness of the affected side and its correlation with the shoulder VAS score and ROM are different for different stages of frozen shoulder.
