Knee Surgery Sports Traumatology Arthroscopy, 2015Co-Authors: Jae Jun Lee, Yonsik Yoo, Jungtaek Hwang, Doyoung Kim, Seongjae Jeon, Sung Mi Hwang, Ji Su JangAbstract:The purpose of this study was to evaluate the outcomes of arthroscopy-guided direct Suprascapular Nerve block performed after arthroscopic rotator cuff repair. In the present prospective, randomized, double-blinded clinical study, 30 patients were divided into two groups: 15 patients (group I) were treated with arthroscopy-guided Suprascapular Nerve block using 10 mL 0.5 % ropivacaine with 1:200,000 epinephrine, and 15 patients (group II) were treated with placebo using 10 mL 0.9 % saline after arthroscopic rotator cuff repair. Patient pain levels were measured using the visual analog scale (VAS) at 1, 3, 6, 12, 18, and 24 h post-operatively. Additionally, the number of boluses and total amount of fentanyl dispensed by patient-controlled analgesia administration during the 24-h post-operative period were evaluated. VAS scores did not differ significantly between groups I and II during the 24-h post-operative period, but mean fentanyl bolus consumption was significantly less in group I compared with group II (p = 0.015). Arthroscopy-guided Suprascapular Nerve block at the end of a rotator cuff repair was safe and less time-consuming than expected. Although this procedure did not significantly reduce the post-operative pain, the post-operative need for fentanyl boluses as analgesia was reduced significantly, and it would be beneficial if this procedure involved a sensory branch of axillary Nerve block or was performed at the beginning of the arthroscopic procedure. Prospective, randomized, double-blinded clinical trial, Level I.

ultrasound guided Suprascapular Nerve block a correlation with fluoroscopic and cadaveric findings
Canadian Journal of Anaesthesia-journal Canadien D Anesthesie, 2010Co-Authors: Philip Peng, Michael J Wiley, James Liang, Geoff A BellinghamAbstract:Purpose Previous work on the ultrasound-guided injection technique and the sonoanatomy of the Suprascapular region relevant to the Suprascapular Nerve (SSN) block suggested that the ultrasound scan showed the presence of the Suprascapular notch and transverse ligament. The intended target of the ultrasound-guided injection was the notch. The objective of this case report and the subsequent cadaver dissection findings is to reassess the interpretation of the ultrasound images when locating structures for SSN block.

evaluation of Suprascapular Nerve radiofrequency ablation protocols 3d cadaveric needle placement study
Regional Anesthesia and Pain Medicine, 2019Co-Authors: John Tran, Philip Peng, Anne AgurAbstract:Background and objectives Image-guided intervention of the Suprascapular Nerve is a reported treatment to manage chronic shoulder joint pain. The Suprascapular Nerve is conventionally targeted at the Suprascapular notch; however, targeting of its branches, the medial and lateral trunks, which are given off just posterior to the notch has not been considered. Since the lateral trunk supplies the posterior supraspinatus and articular branches to the glenohumeral joint capsule, while the medial trunk provides motor innervation to the anterior region, it may be possible to preserve some supraspinatus activation if the medial trunk is spared. The main objective was to investigate whether midpoint between Suprascapular and spinoglenoid notches is the optimal target to capture articular branches of lateral trunk while sparing medial trunk. Methods In 10 specimens, using ultrasound guidance, one 17 G needle was placed at the Suprascapular notch and a second at midpoint between Suprascapular and spinoglenoid notches. The trunks and needles were exposed in the supraspinous fossa, digitized and modeled in 3D. Lesion volumes were added to the models to asses medial and lateral trunk capture rates. Mean distance of needle tips to origin of medial trunk was compared. Results Conventional notch technique captured both lateral and medial trunks, whereas a midpoint technique captured only lateral trunk. Mean distance of needles from the origin of medial trunk was 5.10±1.41 mm (notch technique) and 14.99±5.53 mm (midpoint technique). Conclusions The findings suggest that the midpoint technique could spare medial trunk of Suprascapular Nerve, while capturing lateral trunk and articular branches. Further clinical investigation is required.

Suprascapular Nerve block a narrative review
Regional Anesthesia and Pain Medicine, 2011Co-Authors: Chinwern Chan, Philip PengAbstract:Suprascapular Nerve blockade (SSNB) is a simple and safe technique for providing relief from various types of shoulder pain, including rheumatologic disorders, cancer, and trauma pain, and postoperative pain due to shoulder arthroscopy. Posterior, superior, and anterior approaches may be used, the most common being the posterior. Recently, an ultrasound-guided approach has been described. In this review, the basic anatomy of the Suprascapular Nerve will be described. The different techniques of SSNB and indications for SSNB will be discussed. The complications of SSNB and outcomes of SSNB on the management of acute and chronic shoulder pain will be reviewed.

results of spinal accessory to Suprascapular Nerve transfer in 110 patients with complete palsy of the brachial plexus
Journal of Neurosurgery, 2016Co-Authors: Jayme Augusto Bertelli, Marcos Flavio GhizoniAbstract:OBJECTIVE Transfer of the spinal accessory Nerve to the Suprascapular Nerve is a common procedure, performed to reestablish shoulder motion in patients with total brachial plexus palsy. However, the results of this procedure remain largely unknown. METHODS Over an 11-year period (2002-2012), 257 patients with total brachial plexus palsy were operated upon in the authors' department by a single surgeon and had the spinal accessory Nerve transferred to the Suprascapular Nerve. Among these, 110 had adequate follow-up and were included in this study. Their average age was 26 years (SD 8.4 years), and the mean interval between their injury and surgery was 5.2 months (SD 2.4 months). Prior to 2005, the Suprascapular and spinal accessory Nerves were dissected through a classic supraclavicular L-shape incision (n = 29). Afterward (n = 81), the spinal accessory and Suprascapular Nerves were dissected via an oblique incision, extending from the point at which the plexus crossed the clavicle to the anterior border of the trapezius muscle. In 17 of these patients, because of clavicle fractures or dislocation, scapular fractures or retroclavicular scarring, the incision was extended by detaching the trapezius from the clavicle to expose the Suprascapular Nerve at the Suprascapular fossa. In all patients, the brachial plexus was explored and elbow flexion reconstructed by root grafting (n = 95), root grafting and phrenic Nerve transfer (n = 6), phrenic Nerve transfer (n = 1), or third, fourth, and fifth intercostal Nerve transfer. Postoperatively, patients were followed for an average of 40 months (SD 13.7 months). RESULTS Failed recovery, meaning less than 30° abduction, was observed in 10 (9%) of the 110 patients. The failure rate was 25% between 2002 and 2004, but dropped to 5% after the staged/extended approach was introduced. The mean overall range of abduction recovery was 58.5° (SD 26°). Comparing before and after distal Suprascapular Nerve exploration (2005-2012), the range of abduction recovery was 45° (SD 25.1°) versus 62° (SD 25.3°), respectively (p = 0.002). In patients who recovered at least 30° of abduction, recovery of elbow flexion to at least an M3 level of strength increased the range of abduction by an average of 13° (p = 0.01). Before the extended approach, 2 (7%) of 29 patients recovered active external rotation of 20° and 120°. With the staged/extended approach, 32 (40%) of 81 recovered some degree of active external rotation. In these patients, the average range of motion measured from the thorax was 87° (SD 40.6°). CONCLUSIONS In total palsies of the brachial plexus, using the spinal accessory Nerve for transfer to the Suprascapular Nerve is reliable and provides some recovery of abduction for a large majority of patients. In a few patients, a more extensive approach to access the Suprascapular Nerve, including, if necessary, dissection in the Suprascapular fossa, may enhance outcomes.

transfer of the accessory Nerve to the Suprascapular Nerve in brachial plexus reconstruction
Journal of Hand Surgery (European Volume), 2007Co-Authors: Jayme Augusto Bertelli, Marcos Flavio GhizoniAbstract:Purpose: Transfer of the accessory Nerve to the Suprascapular Nerve is a common procedure, performed to reestablish shoulder motion in patients with brachial plexus palsy. We propose dissecting both Nerves via a distal oblique supraclavicular incision, which can be prolonged up to the scapular notch. The results of the transfer to the Suprascapular Nerve are compared with those of the combined repair of the Suprascapular and axillary Nerves. Methods: Thirty men between the ages of 18 and 37 years with brachial plexus trauma had reparative surgery within 3 to 10 months of their injuries. In partial injuries with a normal triceps, a triceps motor branch transfer to the axillary Nerve was performed. The Suprascapular and accessory Nerves were dissected via an oblique incision, extending from the point at which the plexus crosses the clavicle to the anterior border of the trapezius muscle. In 10 patients with fractures or dislocations of the clavicle, the trapezius muscle was partially elevated to expose the Suprascapular Nerve at the Suprascapular notch. Results: In all cases, transfer of the accessory to the Suprascapular Nerve was performed without the need for Nerve grafts. A double lesion of the Suprascapular Nerve was identified in 1 patient with clavicular dislocation. In those with total palsy, the average improvement in range of abduction was 45°, but none of the patients with total palsy recovered any active external rotation. Patients with upper-type injury recovered an average of 105° of abduction and external rotation. If only patients with C5-C6 injuries were considered, the range of abduction and external rotation increased to 122° and 118°, respectively. Conclusions: Use of the accessory Nerve for transfer to the Suprascapular Nerve ensured adequate return of shoulder function, especially when combined with a triceps motor branch transfer to the axillary Nerve. The supraclavicular exposure proposed here for the Suprascapular and accessory Nerves is advantageous and can be extended easily to explore the Suprascapular Nerve at the scapular notch.
