US-guided Hydro Dissection vs Fluoroscopy-guided Hydro Dissection for Adhesive Capsulitis

All procedures are performed under sterile conditions. The patient is seated in a sitting position with the physician behind the patient, the shoulder joint and the surrounding area is cleaned extensively with 10% povidone iodine. The probe is placed in the posterior lateral region of the shoulder, below the level of the scapular spine. The posterior labrum is observed as a triangular hyperechoic structure extending from the glenoid to the humeral head. A 22 G spinal needle is inserted approximately 1 cm medial to the probe along the axis of the spina scapula and 8 mg (2 mL) dexamethasone, 80 mg (4 mL) 2% lidocaine, 14 mL 0.9% saline is slowly injected into the joint in a total of 20 mL into the glenohumeral region. For suprascapular nerve block, 2 ml 0.5% bupivacaine + 2 ml 0.9% saline is administered. Patients are followed up in the recovery unit for 30 minutes after the procedure.

The patient is placed on the scope table in supine position and the shoulder joint is cleaned with 10% povidone iodine. The acromioclavicular joint and the glenohumeral joint are visualized using C-arm fluoroscopy with anteroposterior view. The acromioclavicular joint is marked as the entry point to the shoulder joint. After the skin and subcutaneous tissue is anesthetized with 1 cc 2% lidocaine with a 27 G needle, a 22 G spinal needle is inserted through the acromioclavicular joint and the needle is directed towards the glenohumeral joint. With 1 ml of contrast medium, the localization of the needle is confirmed. After appropriate spread of contrast agent, 8 mg (2 mL) dexamethasone, 80 mg (4 mL) 2% lidocaine, 14 mL 0.9% saline are administered into the joint in a total of 20 mL. For US-guided suprascapular nerve block, 2 ml 0.5% bupivacaine + 2 ml 0.9% saline is administered. Patients are followed up in the recovery unit for 30 minutes after the procedure.
