Dorsal Scapular Nerve Floss - YouTube Dorsal scapular nerve - e-Anatomy - IMAIOS Because most of the DSNs were observed above line C in the cadaveric dissections, we performed US to find the DSA in the levels of the lines A, B, and C (Fig. Careers. Federal government websites often end in .gov or .mil. Christ S, Rindfleisch F, Friederich P. Superficial cervical plexus neuropathy after single-injection interscalene brachial plexus block. At the level of each line, except for line A, most of the arteries were lateral to the medial border of the scapula, with frequencies of 86.2% (line B), 89.7% (line C), and 86.4% (line D). 3:53. Dorsal scapular nerve neuropathy is a very rare condition, responsible for levator scapulae and rhomboid muscle denervation. Weakness of the shoulder joint, in particular lifting the arm out to the side and rotating it . shoulder, arm, forearm, and hand. Here, the patient is asked to laterally rotate the head away from the affected shoulder and retract the neck. Each DSA branch in these cadavers traveled to a similar location deep to the rhomboid muscles. In US imaging of live subjects, the DSA was most observed at the level of the SA (94.0%). We describe the case of a 17-year-old right-handed male patient who presented to the neurosurgery clinic for evaluation of right upper limb pain and paresthesia of 4-year duration. 1Department of Anesthesiology and Pain Medicine, Wonkwang University Hospital, Wonkwang University School of Medicine, Iksan, Neural Flossing Gliding Exercises for trapped nerves This finding has been previously reported in one study, although it did not report the frequency of these findings.31 Our other results are in fair agreement with several other cadaveric studies identifying the DSA as a direct branch of the subclavian artery in 67 to 75% of cadavers and from the thyrocervical trunk in the remaining cadavers (30%).2 A similar DSA path between middle and lower trunks has been reported in 18.4,3 11,31 and 41% of cadavers.2 The study of Chaijaroonkhanarak et al identified few incidences (6.6%) of the DSA passing inferior to the plexus,3 as did we (4%). Mild scapular winging is encountered. He had a past medical history of asthma, but was otherwise healthy and taking no medications. Lines B, C, E, and F indicate each line divided into three equal parts between the lines A and D, and between the lines D and G, respectively. Grip strength was 70 pounds on the right side, and 100 pounds on the left, despite the patient being right hand dominant. The compound muscle action potential of the right dorsal scapular nerve showed low amplitude (left vs. right side: 5.2 vs. 1.6 mV) and delayed latency (left vs. right side: 4.9 vs. 6.8 ms). Dorsal scapular nerve is a(n) research topic. Injury blog: Dorsal scapular nerve entrapment - Holistic Bodyworks Evaluation and Management of Scapular Winging due to spinal accessory The Dorsal Scapular Nerve (n. dorsalis scapul; nerve to the Rhomboidei; posterior scapular nerve) arises from the fifth cervical, pierces the Scalenus medius, passes beneath the Levator scapul, to which it occasionally gives a twig, and ends in the Rhomboidei. The DSA originated less from the thyrocervical trunk (35% of sides) (Fig. Positive sharp wave (1+) and mildly reduced recruitment were seen on electromyography of the rhomboid major muscle. The first rib was left in situ. The Line G indicates the midpoint between the spine of scapula (line D) and the inferior angle of scapula. Dorsal Scapular Nerve - an overview | ScienceDirect Topics This muscle was cut at its origin and reflected laterally. ( b) The needle is inclined at a 30 angle toward the dorsal direction from the axis of the body and inserted until it reaches the base of the coracoid process. This DSA crossed superior to the C8 ventral ramus just prior to the merger of C8 and T1 ventral rami to form the lower trunk. Isolated dorsal scapular nerve injury is uncommon, with the mechanism believed to be injury to the scalene muscles (10). More female than male sides showed this finding (eight to one; Table 1). After removing the skin and subcutaneous tissue, the trapezius was exposed. Thirty shoulders of 15 embalmed Korean adult cadavers (9 males, 6 females; mean age 80.2 yr at death [range, 5095 yr]) were dissected. DSAs originating from the subclavian artery were more likely to pass between upper and middle trunks on the right side (p=0.016), than on the left (p=0.108).

The Dorsal Scapular Nerve is a little off-shoot of the C5 nerve root which runs from the neck to the back of the shoulder and mid-back. The DSA could be identified using US Doppler imaging, which depicted its pulsation. In these cases, DSN blockade is also possible using a simple injection below the levator scapulae or rhomboid muscles at the levels of lines A, B, and C. The above mentioned position (a position with protraction of the scapula) is also recommended in other lines when the DSA is difficult to find even in clinical practice. Do not execute the exercise too fast. Read W T, Trotter M. The origins of transverse cervical and of transverse scapular arteries in American Whites and Negroes. Nerve Entrapment - Physiopedia 300. It commonly pierces the middle scalene muscle and continues deep to levator scapulae, where it then innervates the rhomboid muscles (Fig. At the levels of lines A, B, and C, the nerve was always medial to the artery (100% of specimens). The DSA has rarely been reported as passing between the roots of C8 and T1. Locations and distances of both the DSN and DSA were measured at each point of the medial border of the scapula, meeting perpendicular lines from the 7 defined points using a digital caliper (Mitutoyo, Tokyo, Japan).

Conflict of Interest The authors have no conflicts of interests to declare. The anatomical relationship of the DSA with the brachial plexus was explored in 155 cadaveric sides (Table 2; see also Supplementary Table S1 [online-only]). It is accompanied by one of two arteries: either the dorsal scapular artery (the . The dorsal scapular and long thoracic nerves course through the neck, where they may become entrapped between or within adjacent scalene muscles. will also be available for a limited time.

Dorsal scapular nerve: Origin, course and function | Kenhub Only 52 cadavers could be examined bilaterally. The mechanism of injury to the DSN is also quite varied ranging from postural to overuse in overhead . Learn more However, reports vary, with some indicating that the DSA originates with more or less the same frequency from the thyrocervical trunk and subclavian artery (50.7 and 49.3%, respectively)1 and others indicating that it originates more often from the subclavian artery (70%),2 and, more recently, more commonly from the thyrocervical trunk with a frequency of 69 to 71%.3 Bilateral symmetry in origin and path through the brachial plexus was observed in 13 of 35 females (37%) and 6 of 17 males (35%), with the most common bilateral finding of a subclavian artery origin and a path between upper and middle trunks (17%). The DSN and DSA were then identified by sticking colored pin-heads at the levels of the defined points (Fig. Case illustration. Pain develops gradually and feels like it is deep within the shoulder joint but may radiate through the arm. The relationship of DSA with the brachial plexus trunks and roots (ventral rami) after origin from the transverse cervical artery or thyrocervical trunk is also understudied. Role of Dorsal Scapular Nerve Entrapment in Unilateral Interscapular The suprascapular nerve arises from the upper trunk of the brachial plexus, which is formed from the anterior rami of the fifth and sixth cervical nerves. Author contributions: Hyunho Cho: Writing/manuscript preparation, Investigation; Seungwoo Kang: Investigation; Hyung-Sun Won: Writing/manuscript preparation; Miyoung Yang: Writing/manuscript preparation; Yeon-Dong Kim: Study conception, Writing/manuscript preparation. Variations include sharing a common branching trunk with the long thoracic nerve, C4 nerve root or C4 and C5 nerve root. Pain in this area may be encountered and may be the only symptom. The .gov means its official. Akgun K, Aktas I, Terzi Y. We suggest that in cases of upper extremity radiating pain, paresthesia, or weakness with obvious proximal etiology, the possibility of a vascular compression of the brachial plexus should be considered. Frequency and distance (mm) of the dorsal scapular artery (A) and dorsal scapular nerve (B) from the medial border of scapula at the level of each line of the cadavers. Below line D, the number of arteries that could be identified using the naked eye clearly decreased. These include problems caused by gingivitis, dental caries (tooth decay), tartar, tobacco and tea stains, etc. 5 There is limited knowledge concerning the anatomical relationship of the DSA with the brachial plexus, especially when the direct origin is from the subclavian artery,2 It also preps the muscles for possible treatment with other methods. Our goal was to report a case of a young patient with TOS due to compression of the lower trunk of the brachial plexus by an anomalous DSA. The structures traverse one another only one time (B), or more than 2 times (C). Neuropathic dysfunction related to chronic DSN entrapment may cause atrophies of the rhomboid or levator scapulae muscles [11]. All cadavers were stored at the Jesaeng-Euise Institute of Wonkwang University School of Medicine, and were qualified as materials for use in education and research according to domestic law. Dorsal scapular nerve (DSN) (Latin: nervus dorsalis scapulae) neuropathy has been a rarely thought of differential diagnosis for mid scapular, upper to mid back pain. 3 We also report bilateral symmetry in both DSA origin and path through the brachial plexus in 13/35 females (37%) and 6/17 males (35%), indicating that for patients undergoing procedures in both posterior triangles, findings from one side should inform the other. Suprascapular nerve block is indicated for relief of acute shoulder pain e.g., after shoulder surgery and is more effective when combined with blockade of the axillary nerve. (A) The DSN and DSA run parallel throughout their course. Four months postsurgery, the patient continued to be free of symptoms with full passive and active range of motion of the shoulder and cervical spine. Stapleton C, Herrington L, George K.

The remaining combinations were much less prevalent (Supplementary Table S1 [online-only]). The prevalence and location of DSAbrachial plexus relationship is highly variable and understudied.3 The DSA often acts as a nutrient artery to brachial plexus trunks and cords,39 supporting our findings of its path through the plexus in 74% of cadavers, rather than superior or inferior to it.

These findings are similar to a prior anatomical study on one cadaver in which a DSA compromised the T1 ventral root.24 The authors hypothesized that in some cases of TOS clinical symptoms might occur when a DSA originates from the third portion of the subclavian artery.24 Our case confirms this hypothesis. The H13 dorsal scapular ARP is needled for all symptoms related to the head, neck, shoulder, arm, and upper back. 24 Besides direct compression by subclavian vessels,25 compression of the brachial plexus by vascular branches has been reported in the literature, although only rarely.26.

The anatomical relationship of the DSA with the brachial plexus was explored in 155 cadaveric sides (Table 2; see also Supplementary Table S1 [online-only]). It is accompanied by one of two arteries: either the dorsal scapular artery (the . The dorsal scapular and long thoracic nerves course through the neck, where they may become entrapped between or within adjacent scalene muscles. will also be available for a limited time. [3] DSN entrapment is typically caused by whiplash injury and overhead work, especially lifting overhead. 8600 Rockville Pike Check out our \"Nerve Flossing Playlist\" - https://qrcodes.pro/QMzAwo NERVE FLOSSING RESOURCESPublications/Books at Amazon https://amzn.to/3zyHCpzFunctional Atlas of the Human Fascial System - Carla Stecco https://amzn.to/3TE1EqPLET'S CONNECTKinetic Health: https://www.kinetichealth.ca Motion Specific Release: https://www.motionspecificrelease.com Instagram: https://www.instagram.com/kinetichealthyyc/ Facebook: https://www.facebook.com/kinetichealth.ca Twitter: https://twitter.com/KineticHealth LinkedIn: https://www.linkedin.com/in/kinetichealth/ PUBLICATIONSDiscover and read Dr. Abelsons internationally best-selling books available online at many bookstores including Chapters/Indigo: https://www.chapters.indigo.ca/en-ca/home/search/?keywords=Brian%20Abelson#internal=1 00:00 Introduction/Anatomy02:17 Nerve flossing exerciseMedical Disclaimer: Nothing in this video, or related to this channel, should be construed as personal advice or diagnosis, and must not be used in this manner. Ozakar L, Kaymak B, Turan S, Akal M, Enn S, Okuyan H. Thoracic outlet syndrome, Paget-Schroetter syndrome and aberrant subclavian artery in a young man. Introduction. Dorsal Scapular Nerve Block (Landmark Method) | SpringerLink At the level of line D (at the scapular spine), the nerve was medial and lateral to the artery in 75% and 25% of subjects, respectively. FOIA One female cadaver had a bilateral incidence of this double branching. Additional vascular compression of the brachial plexus in a cadaver with a cervical rib: case illustration. . On its way to these muscles, the nerve . Ultrasound (US) images and frequency of the detected dorsal scapular artery (yellow arrow) in live subjects. The phrenic nerve is passing over the lower trunk of the brachial plexus. The dorsal scapular artery (DSA) supplies the levator scapulae and rhomboid muscles, and contributes to the arterial anastomosis around the scapula. No knowledge . Kinjo S, Frankel A. One hundred percent incidence of hemidiaphragmatic paresis associated with interscalene brachial plexus anesthesia as diagnosed by ultrasonography. How to get rid of bad breath -Bad breath-By Symptom-Kira Specialist We would like to acknowledge the support of the Department of Anatomy and Cell Biology, Temple University School of Medicine, and Department of Biomedical Sciences of University of New England College of Osteopathic Medicine, which allowed access to the cadavers used in this study. In this case, blocking the entire brachial plexus may be an option for providing nonspecific analgesia to the scapula; however, there is concern about unintentional blockade or injury of the other nerves [7]. Aortic development and anomalies. Nerve entrapment syndromes (meaning a common group of signs and symptoms), occurs in individuals as . Dorsal scapular nerve neuropathy . 30. Suprascapular Nerve Palsy - Physiopedia 1 Upper to mid-thoracic and costovertebral pain and stiffness are a common entity presenting to chiropractic, physiotherapy, massage therapy and medical offices 2 - 4 especially following motor vehicle accidents 5. Leaving the long thoracic nerve, it might give branches to the shoulder and the subaxillary region and finally . Dorsal scapular and long thoracic nerves during ultrasound-guided Flossing the Spinal Accessory Nerve - Once you watch this video you will be able to release entrapments of the Spinal Accessory Nerve, which is commonly associated with shoulder and neck. Dorsal scapular nerve: Origin, course and function | Kenhub Only 52 cadavers could be examined bilaterally. The mechanism of injury to the DSN is also quite varied ranging from postural to overuse in overhead . Learn more However, reports vary, with some indicating that the DSA originates with more or less the same frequency from the thyrocervical trunk and subclavian artery (50.7 and 49.3%, respectively)1 and others indicating that it originates more often from the subclavian artery (70%),2 and, more recently, more commonly from the thyrocervical trunk with a frequency of 69 to 71%.3 Bilateral symmetry in origin and path through the brachial plexus was observed in 13 of 35 females (37%) and 6 of 17 males (35%), with the most common bilateral finding of a subclavian artery origin and a path between upper and middle trunks (17%). The DSN and DSA were then identified by sticking colored pin-heads at the levels of the defined points (Fig. Case illustration. Pain develops gradually and feels like it is deep within the shoulder joint but may radiate through the arm. The relationship of DSA with the brachial plexus trunks and roots (ventral rami) after origin from the transverse cervical artery or thyrocervical trunk is also understudied. Role of Dorsal Scapular Nerve Entrapment in Unilateral Interscapular The suprascapular nerve arises from the upper trunk of the brachial plexus, which is formed from the anterior rami of the fifth and sixth cervical nerves. Author contributions: Hyunho Cho: Writing/manuscript preparation, Investigation; Seungwoo Kang: Investigation; Hyung-Sun Won: Writing/manuscript preparation; Miyoung Yang: Writing/manuscript preparation; Yeon-Dong Kim: Study conception, Writing/manuscript preparation. Variations include sharing a common branching trunk with the long thoracic nerve, C4 nerve root or C4 and C5 nerve root. Pain in this area may be encountered and may be the only symptom. The .gov means its official. Akgun K, Aktas I, Terzi Y. We suggest that in cases of upper extremity radiating pain, paresthesia, or weakness with obvious proximal etiology, the possibility of a vascular compression of the brachial plexus should be considered. Frequency and distance (mm) of the dorsal scapular artery (A) and dorsal scapular nerve (B) from the medial border of scapula at the level of each line of the cadavers. Below line D, the number of arteries that could be identified using the naked eye clearly decreased. These include problems caused by gingivitis, dental caries (tooth decay), tartar, tobacco and tea stains, etc. 5 There is limited knowledge concerning the anatomical relationship of the DSA with the brachial plexus, especially when the direct origin is from the subclavian artery,2 It also preps the muscles for possible treatment with other methods. Our goal was to report a case of a young patient with TOS due to compression of the lower trunk of the brachial plexus by an anomalous DSA. The structures traverse one another only one time (B), or more than 2 times (C). Neuropathic dysfunction related to chronic DSN entrapment may cause atrophies of the rhomboid or levator scapulae muscles [11]. All cadavers were stored at the Jesaeng-Euise Institute of Wonkwang University School of Medicine, and were qualified as materials for use in education and research according to domestic law. Dorsal scapular nerve (DSN) (Latin: nervus dorsalis scapulae) neuropathy has been a rarely thought of differential diagnosis for mid scapular, upper to mid back pain. 3 We also report bilateral symmetry in both DSA origin and path through the brachial plexus in 13/35 females (37%) and 6/17 males (35%), indicating that for patients undergoing procedures in both posterior triangles, findings from one side should inform the other. Suprascapular nerve block is indicated for relief of acute shoulder pain e.g., after shoulder surgery and is more effective when combined with blockade of the axillary nerve. (A) The DSN and DSA run parallel throughout their course. Four months postsurgery, the patient continued to be free of symptoms with full passive and active range of motion of the shoulder and cervical spine. Stapleton C, Herrington L, George K. Sonographic evaluation of the subclavian artery during thoracic outlet syndrome shoulder manoeuvres. The new PMC design is here! hand is coordinated by movements of shoulder girdle, glenohumeral, elbow, radio-ulner, and wrist joints. Maigne JY, Ellis RM. The remaining combinations were much less prevalent (Supplementary Table S1 [online-only]). The prevalence and location of DSAbrachial plexus relationship is highly variable and understudied.3 The DSA often acts as a nutrient artery to brachial plexus trunks and cords,39 supporting our findings of its path through the plexus in 74% of cadavers, rather than superior or inferior to it. Informed consent was obtained from the patients. Bethesda, MD 20894, Web Policies 33 The dorsal scapular nerve is a proximal branch of the brachial plexus.
