In some cases, individuals with pinched cervical nerves suffer from intense daily headaches. It innervates the Supra spinatous muscle and infra spinatus muscles. 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). (teres major, teres minor and the humerus are the other boundaries); all three The cords branch to form several important named terminal peripheral nerve branches. On 19 sides, the dorsal scapular nerve originated solely from the C5 spinal nerve and on 1 side (left) it arose from the C5 and C6 spinal nerves. The quadrangular space provides a passageway for nerves and vessels passing between more anterior regions (the axilla) and the posterior scapular region (Figs. of frequent fracture; fractures of the surgical neck of the humerus endanger Insertion: Action: Nerve Supply . Dorsal scapular nerve syndrome typically presents with a weakness of the levator scapulae and the rhomboid muscles, and results in a winged scapula. It is a pathway for neurovascular structures to move from the axilla anteriorly to the posterior shoulder and arm. shoulder joint capsule, the articulation between the head of the humerus and the glenoid fossa of It is found just proximal to the upper trunk of the brachial plexus. This … The fibres attach to the clavicle, acromion, and the scapula spine. scapula into a supraspinatous fossa and an infraspinatous fossa, a notch on the superior border of the scapula located medial to the attachment Tailor each patient's rehabilitation program to be as unique as each injury. 2-2). The faces/smooth surfaces of the scapula. The remaining minor and all major terminal nerve branches arise from the BP proper. It innervates three muscles: the levator scapulae, the rhomboid major, and the rhomboid minor. The pleural cavities contain the lungs. The dorsal scapular nerve originates in the fifth cervical nerve root. It is helpful to divide the back muscles into three main layers: Superficial layer: Consists of muscles that attach the upper extremity to the spine. pulling the scapula forwards around the chest wall during pushing & punching actions. Go to the Pelvis and Perineum Tables page... the scapula floats in a sea of muscles, so it is difficult to fracture; It innervates the Supra spinatous muscle and infra spinatus muscles. coracobrachialis m., the pectoralis minor m. and the coracoacromial and coracoclavicular As with the ISB, supplemental blocks are required for elbow procedures (i.e., intercostobrachial). We use cookies to help provide and enhance our service and tailor content and ads. tendon; it provides support for the head of the humerus that prevents superior mechanical advantage it cannot initiate this action; it is assisted by the Suprascapular nerve entrapment is a rare condition that can be easily misdiagnosed or even go unnoticed by those who are affected. The blood supply to the thoracic spinal cord is less abundant than in the cervical or lumbar region. 6 What are the Boundaries and Contents of Intermuscular Spaces in the Scapular Region. The area of neurologic loss after nerve injury can commonly help diagnose the location of nerve injury. The brachial plexus is a grouping of nerves where the last three cervical nerves nerves C-6, C-7, and C-8 and the first two thoracic nerves T-1 to T-2 descend ventrally. Damage to the long thoracic nerve will lead to “winging” of the scapula. Paul Rea MBChB, MSc, PhD, MIMI, RMIP, FHEA, FRSA, in Essential Clinically Applied Anatomy of the Peripheral Nervous System in the Limbs, 2015. Quadrangular space. Depending on the cranial or caudal variation of the nerves supplying the BP, it can be defined as prefixed or postfixed. Lesser tubercle of humerus. First, extraspinal pathologic processes within the thoracic cavity (e.g. to the 1st rib). For some, amputation and prosthetic restoration may be an option, but this is not a treatment for neuropathic pain. Supraspinous fossa. Of all the brachial plexus blocks, the supraclavicular block has the highest risk for pneumothorax, especially when done with the traditional “plumb bob” technique. Learn vocabulary, terms, and more with flashcards, games, and other study tools. passes superior to the ligament and the suprascapular n. passes inferior to 4 Describe Briefly the Musculotendinous or Rotator Cuff.

Nerve Supply: Long thoracic nerve (C 5,6,7). it is the attachment site for the tendon of the long head of the biceps Subscapular fossa. Insertion: It shows insertion on medial lip of intertubercular sulcus. Action: It is the lateral rotator of humerus also help in abduction at shoulder joint by fixing head of humerus. We investigated the characteristics of the scapular pain and whether it is caused by cervical radiculopathy when the dorsal rami of the cervical nerves are distributed below the traditional cervicothoracic line, with a view to corresponding the involved nerve root. SCAPULAR REGION This is the region that lies at the posterior thoracic wall. 1st part: superior thoracic a.; 2nd part: thoracoacromial a., lateral thoracic Upper and lower subscapular nerves. Teres major Origin: From dorsal surface of lateral border lower 1/3 part and inferior angle of scapula. Second, surgical treatment of many types of spinal problems involves exposure of the anterior aspect of the thoracic spine. Distinguish between pre and post-ganglionic injury because there is little chance of spontaneous recovery in preganglionic avulsion injuries without surgical intervention. Scapulothoracic bursitis and snapping scapula syndrome: a critical review of current evidence. shoulder joint capsule, it connects the humerus to the scapula; a thickening of the anterior shoulder Also, the deltoid muscle must be dissected prior to the scapular region muscles, located underneath the deltoid muscle (Fig. Medial rotation of humerus. The cause of pain in the area of the scapula on the left is the abnormal operation of the nerve endings of the diaphragm. It then travels behind the brachial plexus and axillary artery and vein as it courses down the lateral side of the thorax. from the greater tubercle. Scapular Where all nerves originate in the scapular region. 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. Devlin MD, Darren L. Bergey MD, in Spine Secrets Plus (Second Edition), 2012. 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 2012 Oct 18. 2-1. 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)). (axillary a. is the continuation of the subclavian lateral superior border of the scapula, it is the attachment site for the short head of the biceps brachii m., the 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 weakness can be caused by a nerve (neurogenic) or muscle (myopathic) condition. The dorsal scapular nerve originates in the fifth cervical nerve root. the biceps tendon in place; it is the attachment site for the tendon of the Related Issues. the transverse humeral ligament spans the intertubercular groove and holds of back muscles, the angle of the scapula formed at the union of the superior and medial Once branching from the brachial plexus, the DSN pierces the middle scalene muscle, coursing deep to levator scapulae and the rhomboid muscles. 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. extend & laterally rotate the arm, axillary nerve (C5,6) from the posterior cord of the brachial plexus. Action: Starts abduction of the arm (from 0° to 15°). The suprascapular nerve originates in the base of the neck from the superior trunk of the brachial plexus. scapular region is often associated with a cervical nerve root block. The dorsal scapular nerve traveled intertwined with the dorsal scapular artery in all specimens and was found along the anterior border of the rhomboid muscles. Just as someone having a heart attack can feel left arm pain and no chest pain, pain around the scapula can be caused by the neck, even if you have no neck pain. Once branching from the brachial plexus, the DSN pierces the middle scalene muscle, coursing deep to levator scapulae and the rhomboid muscles. Unless the local anesthesic tracks proximally toward the interscalene region, this block may be inadequate for shoulder surgery, but it provides adequate block for upper arm surgery.
