Bupivacaine Liposome Versus Bupivacaine for Ultrasound-Guided Suprascapular Nerve Combined With Axillary Nerve Block in Analgesia After Arthroscopic Shoulder Surgery

This trial is designed to compare the post-operative analgesic efficacy and safety of liposomal bupivacaine versus plain bupivacaine when both are used for ultrasound-guided combined suprascapular and axillary nerve block in patients undergoing elective arthroscopic shoulder surgery.

Suprascapular Nerve Block and Proprioception in Hemiplegic Shoulder Pain: A Randomized Controlled Study

The purpose of this prospective randomized controlled clinical trial is to evaluate the effect of suprascapular nerve block on shoulder joint proprioception in stroke patients with hemiplegic shoulder pain. Fourteen patients aged 18-80 years with hemiplegic shoulder pain will be randomized into two groups. One group will receive suprascapular nerve block followed by a standardized physical therapy program, while the control group will receive the same physical therapy program alone. The primary outcome is shoulder joint proprioception. Secondary outcomes include pain intensity, shoulder range of motion, motor recovery, stroke-specific quality of life, and upper extremity functional outcomes. The results of this study are expected to clarify the role of suprascapular nerve block on proprioception and rehabilitation outcomes in patients with hemiplegic shoulder pain.

Suprascapular Nerve Block in the Management of Patients Diagnosed With Adhesive Capsulitis

This study aims to compare the efficacy of different suprascapular nerve block techniques in patients diagnosed with adhesive capsulitis. Adhesive capsulitis, commonly known as frozen shoulder, is a condition characterized by pain and restricted range of motion in the shoulder joint, significantly affecting quality of life. The suprascapular nerve provides sensory innervation to the shoulder joint; therefore, nerve blockade is frequently used to alleviate pain. However, there are limited studies evaluating the difference in efficacy between proximal and distal suprascapular nerve blocks. In this research, two different blockade techniques-at the suprascapular notch and the spinoglenoid notch-will be compared in patients diagnosed with adhesive capsulitis at Istanbul University-Cerrahpaşa between 2024 and 2026. The hypothesis of the study is that the block performed at the spinoglenoid notch provides pain relief comparable to the suprascapular notch block while resulting in less motor blockade. Patients participating in the study will be randomly assigned to two groups. Both groups will receive an intra-articular corticosteroid injection into the shoulder joint, along with cold application, Codman exercises, and standard medical therapy. Pre- and post-treatment evaluations will include pain severity (NRS), shoulder function (Modified Constant Score), muscle strength, and range of motion. The results will reveal which technique provides better improvement in shoulder external rotator and abductor muscle strength, shoulder function, and pain relief, thereby offering valuable insights to guide treatment approaches.

Ultrasound Guided Interscalene, Suprascapular and Anterior Glenoid Nerve Blocks on Diaphragmatic Excursion and Analgesia Following Arthroscopic Shoulder Surgery

This study aims to evaluate the diaphragmatic movement and postoperative analgesia following anterior glenoid, suprascapular, and interscalene nerve blocks in patients undergoing elective arthroscopic shoulder surgery.
