Erector Spinae Plane Block Versus Infraspinatus-Teres Minor Interfascial Plane Block for Analgesia After Shoulder Arthroscopy

The shoulder, being an anatomical region innervated by different nerves, has a wide variety of analgesic approaches, which differ depending on the practitioner. New approaches are being developed based on the different innervation channels demonstrated in clinical and cadaver studies. Over time, the effectiveness of axillary block, suprascapular block, interscalene block, local infiltration, and various combinations, as well as non-regional methods, has been observed. The goal of these approaches is to achieve the highest possible level of patient comfort, high analgesic efficacy, and minimal complications. Studies have shown that the interscalene block has the highest analgesic efficacy and the most ideal postoperative results; therefore, it is frequently used as the gold standard in this field. Providing effective analgesia with a single intervention can also be cited as an aspect that increases patient comfort and simplifies the procedure. In interscalene block; unilateral transient diaphragmatic paralysis due to the spread of local anesthetics to the C7 nerve root, respiratory problems and potential spinal/epidural complications, new approaches are being followed and researched. Results from cervical/high thoracic erector spinae plane block (ESPB) and infraspinatus-teres minor interfascial plane block (ITMIPB) studies, which are the subject of new studies, strengthen the hypothesis that they provide effective analgesia. Neither of these blocks, performed with ultrasonography, carries the risks present in interscalene block. Although the usual risks of a peripheral nerve block are present for these procedures; the block sites are considered safer due to its distance from vascular structures and the reduced risk of additional complications. While small sample studies exist for each type of block, no studies comparing their effectiveness have been found. Besides reduced complications, another advantage of these two blocks is their ability to provide effective analgesia with a single-point injection. The aim of this study is to compare the analgesic efficacy of Cervical Erector Spine Plane Block (ESP) and Infraspinatus-Teres Minor Interfascial Plane Block (ITMIPB) applied for postoperative analgesia in ASA I-III patients undergoing shoulder surgery.

Is Pericapsular Nerve Group Block Better Than Interscalene Nerve Block Regarding Effect on Hand Movement in Shoulder Scope Surgeries?

The goal of this clinical trial is to learn if pericapsular nerve group block (PENG) in shoulder scope surgery provides adequate analgesia with less affection of muscle power compared to interscalene block. The main questions it aims to answer are: Does PENG block provide analgesia similar to interscalene block? Does PENG block have less or no effect on muscle power compared to interscalene block? Researchers will compare PENG block with interscalene block Participants will: Receive either PENG or interscalene block before shoulder scope surgery Be evaluated for their motor power after receiving the block and after the surgery Be evaluated for pain after the surgery

Loop vs. Anchor Tenodesis of the Long Head of the Biceps Brachii Tendon

The goal of this clinical trial is to learn if loop tenodesis is as effective as suture anchor tenodesis for treating long head of biceps (LHB) pathology. It will also assess the safety and outcomes of both techniques. The main questions it aims to answer are: How effective is loop tenodesis compared to suture anchor tenodesis in preventing shoulder deformities and maintaining biomechanical strength? What complications or failures occur with each technique? Researchers will compare suture anchor tenodesis using the Arthrex FiberTak system with loop tenodesis (an implant-free technique). Participants will: Undergo surgery with either suture anchor tenodesis or loop tenodesis, assigned randomly. Be informed about the procedure and sign a consent form prior to surgery. Have their clinical outcomes evaluated and compared before and after their treatment.
