Ultrasound guidance allows visualization of the glenohumeral joint and can improve the accuracy of the injection. Ultrasound-guided intra-articular injection can be performed via an anterior, posterior, or rotator cuff interval approach. This review article aims to summarize and discuss the most effective approach with ultrasound guided intra-articular injection for frozen shoulder. Also this review to introduce hydraulic distension with ‘pumping technique’ to obtain the maximal stretching effect on the capsule.
