Why should a spine specialist understand the anatomy of the thoracic cavity? rim called the glenoid labrum, a projection of bone located superior to the glenoid cavity. the action; a member of the rotator cuff group, greater tubercle of the humerus (middle facet), infraspinatus, supraspinatus, teres minor and subscapularis are the rotator 200. The dorsal scapular nerve (C5) supplies the levator scapulae and rhomboid muscles; it aids in elevation and adduction of the scapula toward the spinal column. Go to the Pelvis and Perineum Tables page... the scapula floats in a sea of muscles, so it is difficult to fracture; a. to form the scapular anastomosis; dorsal scapular a is a branch of the transverse it forms the medial lip of the intertubercular groove; it is the attachment Chronic neuropathic pain as a result of plexus injury will lead to central neural changes that increase the pain response. articular disk occurs within this joint capsule, the ligament that connects the coracoid process to the acromion of the scapula, it passes superior to both the head of the humerus and the supraspinatus In an anatomic study (Tubbs, Tyler-Kabara, et al., 2005a) we found that the dorsal scapular nerve pierced the middle scalene muscle at a mean distance of 3 cm (range 1.8-4.5 cm) from its origin from the cervical spine and was more or less centrally located at this exit site. Upper limb is made up of 4 parts Shoulder region Pectoral/Breast region Axilla/Armpit Scapular region Arm/Brachium Forearm/Antebrachium Hand/Manus … Axillary Nerve Ulnar Nerve Subscapularis Muscle Supraspinatus Muscle Upper Limb Anatomy Acromioclavicular Joint Human Muscle Anatomy Shoulder Anatomy Human Body Once branching from the brachial plexus, the DSN pierces the middle scalene muscle, coursing deep to levator scapulae and the rhomboid muscles. The author suggests the following needling methods, but the practitioner should ensure that the needle is always outside the rib cage: In a thinner patient, a 2.5-cm-long needle is directed horizontally and either inferiorly or laterally, to ensure entrance into the muscle but remaining outside the rib cage.

Pain management aims to help with participation in rehabilitation. As with the ISB, supplemental blocks are required for elbow procedures (i.e., intercostobrachial). It is essential to test the full range of movements of the scapula when undertaking clinical examination. 43(1):236-45. of the circumflex scapular a. the angle of the scapula formed by the union of the medial and lateral borders, the inferior angle of the scapula often has a slip of origin of the latissimus Stabilisation of shoulder joint. Furthermore, the middle portion of the trapezius muscle, which is innervated by the spinal accessory nerve, may mimic the action of the rhomboids. Supraclavicular plexopathies (frequently due to traction injuries) are more common, more severe, and with variable outcome. Marie N. Hanna, ... Vicente Garcia Tomas, in Practical Management of Pain (Fifth Edition), 2014, The supraclavicular block is considered the spinal of the arm. The BP contributes to several nerves originating above the BP proper, including the dorsal scapular nerve, long thoracic nerve, nerves to scalene/longus colli muscles, and a branch to the phrenic nerve. joint, the constricted region located inferolateral to the head, it is located at the circumference of the smooth articular surface of the For some, amputation and prosthetic restoration may be an option, but this is not a treatment for neuropathic pain. Weakness or paralysis of the muscle is the commonest cause of scapular winging. Injury to the long thoracic nerve or the dorsal scapular nerve suggest a more proximal injury because both originate at the root level. brachii m. a heavy ridge that runs from the medial border of the scapula to the acromion Highest tubercle of greater tubercle. First, extraspinal pathologic processes within the thoracic cavity (e.g. could result from a fall on the point of the shoulder, a ligament reinforcing the anterior wall of the capsule of the glenohumeral The thoracic cavity contains the pleural cavities and the mediastinum. Lateral one-third of clavicle, acromion, spine of scapula: Innervation: Motor-accessory nerve [XI]; proprioception-C3 and C4: Artery: Transverse cervical artery, dorsal scapular artery: Action: Assists in rotating the scapula during abduction of humerus above horizontal; upper fibers elevate, middle fibers adduct, and lower fibers depress scapula suprascapular a. and the dorsal scapular a. in the scapular anastomosis, supraspinatus & infraspinatus, shoulder joint, anastomoses with the circumflex scapular a. and the dorsal scapular a. to At times, scapula pain can be caused by issues not directly physically linked to the region. In some cases, individuals with pinched cervical nerves suffer from intense daily headaches. We use cookies to help provide and enhance our service and tailor content and ads. 7.25), both of which originate from the brachial plexus in the axilla. If this is difficult, the alternative method is to needle this point perpendicularly with four or five 1.5-cm-long needles. 2-15). While it is more likely to be a problem affecting the nerve leading to muscle weakness, occasionally it could be due to a disease affecting the muscle directly. The remaining minor and all major terminal nerve branches arise from the BP proper. Insertion: It shows insertion on medial lip of intertubercular sulcus. Anatomically, the BP is classically divided sequentially (proximal to distal) into 5 segments: Roots/rami, trunks, divisions, cords, and terminal branches. The trapezius (innervated by spinal accessory nerve), latissimus dorsi (thoracodorsal nerve), and levator scapulae muscles (dorsal scapular nerve) overlie the deeper rhomboid major and minor muscles (dorsal scapular nerve) (Fig. The ends of these nerves reached the middle of the scapula, and the course of the medial branches of cervical nerve roots veered more to the caudal side than the traditional cervicothoracic line.14,15 It is possible that the skin in the scapular region was doubly innervated from another segment. (axillary a. is the continuation of the subclavian lateral Nerve supply: From a branch of axillary nerve C5 C6 this branch shows a small pseudo ganglion. It begins in the neck, and attach to the scapula. By continuing you agree to the use of cookies. Quadrangular space. Yun-tao Ma, in Acupuncture for Sports and Trauma Rehabilitation, 2011. acromioclavicular joints, the superior border of the scapula is marked by the scapular notch laterally, the border of the scapula that runs from the superior angle to the inferior The wrist and fingers cannot be extended, and wristdrop occurs. The dorsal scapular nerve may share a common trunk with the long thoracic nerve. The area of neurologic loss after nerve injury can commonly help diagnose the location of nerve injury. The two major nerves of the posterior scapular region are the suprascapular and axillary nerves (see Fig. Supraspinatus. it is the attachment site for the tendon of the long head of the biceps Describe the anatomy of the posterior muscles of the thoracic and lumbar spinal regions. The dorsal scapular nerve originates from the fifth cervical spinal nerve (ventral ramus) in the majority (75%) of cases, within the posterior cervical triangle deep to the prevertebral fascia. In the present study, ... below the circumflex scapular artery. The 3 trunks include the superior or upper (C5-C6), middle (C7), and inferior or lower (C8, T1) trunks. David L. Felten MD, PhD, ... Mary Summo Maida PhD, in Netter's Atlas of Neuroscience (Third Edition), 2016. it articulates with only one bone - the clavicle at the coracoclavicular and from the greater tubercle. Once the nerve leaves C5 it commonly pierces the middle scalene muscle, and continues deep to levator scapulae and the rhomboids (minor superior to major). Arising from the C5, 6 and 7 roots, the long thoracic nerve emerges through the medial scalene muscle, runs deep to all three trunks of the brachial plexus, and supplies serratus anterior. The suprascapular nerve (C5–C6) supplies the supraspinatus and infraspinatus muscles; it aids in lifting and in outward rotation of the arm. Topographic Anatomy of the Shoulder Region. Where all nerves originate in the scapular region. However, the supraclavicular block misses the dorsal scapular nerve arising from the root of C5 and also misses the superficial cervical plexus. Also, the lower portions of the serratus anterior may receive innervation from the intercostal nerves in as many as 25% of specimens (Erdogmus & Govsa, 2005). The deltoid muscle is innervated by the scapular region nerve (axillary nerve) (Fig. The dorsal scapular nerve originates from the C5 spinal nerve and innervates the rhomboid minor, rhomboid major, and levator scapulae muscles located in the dorsal aspect of the rib cage. These muscles of accessory respiration are innervated by the anterior primary rami of segmental nerves (Fig. The dorsal scapular nerve was found to have a mean distance of 2.5 cm (range 1.2-3.8 cm) medial to the spinal accessory nerve as it traveled on the anterior border of the trapezius muscle. 1st part: superior thoracic a.; 2nd part: thoracoacromial a., lateral thoracic Start studying Muscles, nerves, and vessels of the shoulder region. Diagnostic accuracy of scapular physical examination tests for shoulder disorders: a systemic review. This nerve enters the levator scapulae muscle approximately 1  cm superior to the base of the spine of the scapula (Fig. The European Spine Journal reported that frequent headaches may be a sign of cervical radiculopathy. The intercostal artery and vein are located along the inferior surface of the rib. of frequent fracture; fractures of the surgical neck of the humerus endanger The anatomy of the dorsal scapular nerve (DSN) and its communication with the long thoracic nerve (LTN) can also be important for understanding the aetiology of muscular pain related to the shoulder regions and also for proper management of conditions such as winging of scapula and pain in the interscapular region [7-9]. in its actions, long head: infraglenoid tubercle of the scapula; lateral head: posterolateral Structure. Of all the brachial plexus blocks, the supraclavicular block has the highest risk for pneumothorax, especially when done with the traditional “plumb bob” technique. Nerve Supply: Long thoracic nerve (C 5,6,7). The long thoracic nerve is typically comprised of fibers from the fifth, sixth, and seventh cervical nerves; however, the upper digitations of the serratus anterior may independently receive a branch from the fourth and fifth cervical nerves in a small percentage of cases (5% (Horwitz & Tocantins, 1938; Tubbs et al., 2006)). The plexus is blocked at the level of the trunks and divisions. An intact long thoracic nerve in the presence of an otherwise flail arm may be a more specific indicator of a postganglionic injury to the upper cervical nerves. Mark A. Mahan, Robert J. Spinner, in Nerves and Nerve Injuries, 2015. Nerve supply: From a branch of axillary nerve C5 C6 this branch shows a small pseudo ganglion. 4 Describe Briefly the Musculotendinous or Rotator Cuff. Attachments of the Levator Scapulae Muscle Origin: Transverse processes of the C1-C4 vertebrae Insertion: Medial border of the scapula Nerve supply of the Levator Scapulae Muscle Innervation: The dorsal scapular nerve. heads of origin insert by a common tendon, greater tubercle of the humerus (highest facet), suprascapular nerve (C5,6) from the superior trunk of the brachial plexus, supraspinatus initiates abduction of the arm, then the deltoid muscle completes Nerves that innervate intrinsic muscles of the scapular region:4-Supra scapular nerve: The suprascapular nerve arises from the upper trunk (formed by the union of the fifth and sixth cervical nerves. to the 1st rib). a., subscapular a. pectoral region, shoulder region and upper limb, pectoralis minor m. crosses anterior to the axillary artery and is used subscapularis m., teres major m., teres minor m., infraspinatus m. the circumflex scapular branch of the subscapular a.anastomoses with the At lower volumes of local anesthestic, the supraclavicular block misses the dorsal scapular nerve, which arises from the root of C5, and also misses the superficial cervical plexus. the projection located lateral to the head of the humerus on the anterior 2-6). There are two important reasons why a spine specialist must possess a working knowledge of anatomy and pathology relating to the thoracic cavity. Medial rotation of humerus. Learn vocabulary, terms, and more with flashcards, games, and other study tools. humerus & lateral intermuscular septum; medial head: posteromedial surface process, it supports the acromion process; it divides the posterior surface of the A lesion results in weakness in the first 15 degrees of abduction and in external rotation of the arm. and the long head of the triceps brachii m. laterally, the circumflex scapular vessels are located in this space as they pass from The H13 dorsal scapular ARP is formed at this neuromuscular attachment. Abduction of arm. However, the needling is very tricky because the lung is directly under this ARP and under both the rhomboid muscles. The fibres attach to the clavicle, acromion, and the scapula spine. The muscles comprising this deep layer can be subdivided into three layers: Sacrospinalis (erector spinae), subdivided into spinalis, longissimus, and iliocostalis portions in the thoracic region, Semispinalis, multifidi, rotatores, intertransversari, and interspinales. What does the posterior circumflex humeral artery supply? For more effective treatment, the forearm of a patient is laid under the back with a 90-degree flexion in order to raise the scapula, and a 4-cm-long needle is directed laterally at this point. Suprascapular nerve. dorsi attached to it, the articular surface located at the junction of the superior and lateral Describe Briefly the Clavipectoral Fascia. 2743799. borders. The suprascapular nerve is a nerve that branches from the upper trunk of the brachial plexus. Supraspinatus. it is an important site of attachment for the teres major m. and teres Innervation: Motor innervation is from the accessory nerve.

Nerves that innervate intrinsic muscles of the scapular region:4-Supra scapular nerve: The suprascapular nerve arises from the upper trunk (formed by the union of the fifth and sixth cervical nerves. The dorsal scapular nerve originates in the fifth cervical nerve root. Two divisions are described: Anterior division innervates anterior (flexor) muscles and posterior division innervates posterior (extensor) muscles. Acromion. Adductor muscles of the scapular region. The cords branch to form several important named terminal peripheral nerve branches. Clinically, the BP is divided into 3 discrete segments based on anatomic relationship to the clavicle. The roots from C5 and C6 pierce through the medial scalene muscle to join the C7 nerve root. Teres major Origin: From dorsal surface of lateral border lower 1/3 part and inferior angle of scapula. It then travels behind the brachial plexus and axillary artery and vein as it courses down the lateral side of the thorax. Teres major Origin: From dorsal surface of lateral border lower 1/3 part and inferior angle of scapula. brachii m. medially and humerus laterally, the radial n. passes through this interval to get from the axilla to the The dorsal scapular nerve branches from the ventral ramus of C5 and descends from the cervical region down to the medial border of the scapula. A related pain is myofascial pain. It innervates the Supra spinatous muscle and infra spinatus muscles. 5 Describe Subacromial bursa. from the lesser tubercle. Action: It is the lateral rotator of humerus also help in abduction at shoulder joint by fixing head of humerus. It is very common over the scapula region, as bedridden patients often lie on their backs.

Image 1: Arteries and nerves of the scapular region as seen within the anatomical spaces of the shoulder: The first image you will work through involves the arteries and nerves of the scapular region as seen within the anatomical spaces of the shoulder. Brian A. Williams, ... Christopher L. Wu, in Raj's Practical Management of Pain (Fourth Edition), 2008. The long thoracic nerve arises from the ventral rami of cervical nerves C5, C6, and C7.1 In some people, the root from C7 is absent, and in others, there is a small root of the nerve arising from C8. The same method can be used to needle both the rhomboid muscles and the subscapularis muscle, which lies on the costal surface of the scapula. pectoralis major (lateral lip), teres major (medial lip), and latissimus dorsi It also receives proprioceptor fibres from C3 and C4 spinal nerves. Despite some attractive advantages of this block, for example, rapidity of onset and broad upper extremity coverage, this block remains the least common brachial plexus block to be performed for postoperative analgesia, and recent literature on this approach is sparse. shoulder joint capsule, it connects the humerus to the scapula; a thickening of the anterior shoulder it forms the lateral lip of the intertubercular groove; it is the attachment Second, surgical treatment of many types of spinal problems involves exposure of the anterior aspect of the thoracic spine.

Upper and lower subscapular nerves. aneurysm, malignancy) may mimic the symptoms of thoracic spinal disorders. The quadrangular space is a gap in the muscles of the posterior scapular region. Treatment of dorsal scapular nerve syndrome tends to be conservative but if surgery is contemplated, an MRI scan should be arranged (Pećina et al., 2001). Supraspinous fossa. These muscles should be treated in most patients. mm. Stabilisation of shoulder joint. The nerves descending from the brachial plexus, along the scapulae and down the humerus include the suprascapular nerve, subscapular nerve, axillary nerve, musculocutaneous nerve, radial nerve, and the median nerve . Upper and lower subscapular nerves. MD, in Practical Management of Pediatric and Adult Brachial Plexus Palsies, 2012.

Tailor each patient's rehabilitation program to be as unique as each injury. The long thoracic nerve is only a motor nerve and it innervates the Serratus Anterior muscle. Insertion: Action: Nerve Supply . Runs through quadrangular space with axillary nerve & joins anterior circumflex humeral artery behind humerus. A lesion may be caused by dislocation of the shoulder joint or a fracture of the surgical neck of the humerus and results in deltoid atrophy, in weakness in abduction from 15 degrees to 90 degrees, and in loss of cutaneous sensation over the lower half of the deltoid. Scapular As with interscalene block, supplemental blocks are required for elbow procedures (i.e., intercostobrachial). 3 Write Origin, Insertion, Action & Nerve Supply of Muscles of Scapular Region. angle, it is an important site of muscle attachments for the intermediate layer It innervates three muscles: the rhomboids major and minor, and the levator scapulae. Also, as pain in the left shoulder region, pain in the right shoulder region may be a symptom of various diseases. joint; it is frequently dislocated, the joint what connects the clavicle with the sternum, a synovial joint; its joint capsule is subdivided by a fibrous articular The axillary nerve (C5–C6) supplies the deltoid and teres minor muscles; it aids in abduction of the arm to the horizontal and in outward rotation of the arm. Some recent studies have shown that the calculated volume of local anesthetic required for an ultrasound-guided supraclavicular block does not seem to differ from the conventionally recommended volume required for supraclavicular blocks performed with non–ultrasound-based nerve localization techniques.227 The minimum effective volume of 1.5% lidocaine with 5 µg/mL epinephrine was 32 mL.228 Multiple studies have confirmed that when UGRA is used, a single injection offers the same clinical profile and analgesic benefit as two injections.229,230, Vincent J.
