Direct Coracohumeral Ligament Steroid Injection Clinical Trial
Official title:
Efficacy of Corticosteroid Injection Into Coracohumeral Ligament in Patients With Adhesive Capsulitis of the Shoulder
Steroid injections are widely utilized to reduce inflammation and fibrosis in patients with the frozen shoulder. In this study, investigators will compare intra-articular steroid injections with direct coracohumeral ligament steroid injection to conventional intra-articular steroid injection. Investigators will measure the primary outcome as shoulder function improvement and secondary outcomes as ROM, pain scale and stiffness of coracohumeral ligament under elastogram.
Adhesive capsulitis of the shoulder, also known as the frozen shoulder, often leads to
severe pain and shoulder range of motion limitation. Steroid injections are widely utilized
to reduce inflammation and fibrosis. The thickening of the coracohumeral ligament was
thought to play an important role in the pathogenesis of frozen shoulder, resulting in
limited external rotation of the shoulder. While the elastogram of coracohumeral ligament
will significantly increase stiffness under the shear-wave ultrasound (shear-wave
elastography).
Therefore, in this study, investigators will compare intra-articular steroid injections with
direct coracohumeral ligament steroid injection to conventional intra-articular steroid
injection. Investigators will measure the primary outcome as shoulder function improvement
and secondary outcomes as ROM, pain scale and stiffness of coracohumeral ligament under
elastogram.
