Often soft tissue adhesions produce mild amounts of inflammation and irritation around the muscles, tendons, and ligaments. Conservative treatment goals are to decrease muscle spasms, increase muscle control, and provide back and shoulder pain relief. for more anatomy content please follow us and visit our website: www.anatomynote.com. This is a common site of the nerve entrapment or compression. When patients feel pain radiating from their back down their arm, they often think of thoracic disc lesions, nerve root compressions (pinched nerves), thoracic outlet syndrome, and nerve traction injuries. This cycle of pain, spasm, posture changes, and dysfunction slowly progresses over months leading to the syndrome’s development. Nerve compression or entrapment can produce a dull, aching pain along the medial border of the scapula which can radiate down the lateral surface of the arm and forearm. By Dr Peter de Souza. Alternative and conservative treatments address the offending muscles or soft tissue adhesions that are compressing the nerve and producing nerve damage. The excessive motion and movement of the scapula shifts the glenohumeral joint angle and produces more stress and strain on all of the shoulder muscles, including the deltoid, teres minor, teres major, infraspinatus, supraspinatus, subscapularis, bicep, or coracobrachialis muscles. Surgical intervention may be utilized in some cases. The latter is one of three arteries branching off the thyrocervical trunk, a branch of the first part of the subclavian artery, with the other two branches being the suprascapular artery, and the inferior thyroid artery. With advances in technology and the development of knowledge and skills of treating practitioners, it has become apparent that this problem is much more common than originally thought. Infraspinatus The structure indicated is the infraspinatus muscle of the rotator cuff. Pushups with an exercise ball are a great activity for increasing strength and endurance in the shoulder stabilizers.

The suprascapular nerve is a nerve that branches from the upper trunk of the brachial plexus. Subscapularis (it is not considered one of the posterior muscles, it is found anteriorly on the scapula) Subscapular fossa Lesser tubercle Upper and lower subscapular nerves. PECTORAL AND SCAPULAR REGIONS THE SCAPULA: • Supraspinatus Fossa: Depression in the scapula, above the scapular spine. Created by. An MRI provides information on the soft tissue of the cervical spine, discs, and neck muscles. STUDY. The two major nerves of the posterior scapular region are the suprascapular and axillary nerves (see Fig. 5.1 Share this: Often these muscles have been in prolonged spasm for months and years with overuse. The infraspinatus muscle is one of the four muscles of the rotator cuff. Match. Continued muscle spasms alter neck and back posture, leading to more strain and spasm of the scalene and neck muscles. The suprascapular nerve originates in the base of the neck from the superior trunk of the brachial plexus. The first involves potential nerve compression in the cervical region where the nerve actually perforates the middle scalene muscle and curves around the posterior scalene before making its way into the upper-thoracic and mid-scapular region. With the levator scapulae muscle the upper fibers elevate the scapular. Clinically this seems very likely because of the importance these muscles play in shoulder stabilization. Physical 3) Propose a differential diagnosis of scapular injury. It is found just proximal to the upper trunk of the brachial plexus. Module. Dorsal surface of lateral margin of scapula below teres minor. Because dorsal scapular nerve entrapment leads to dysfunction in scapular stabilization, the first recognized symptom is tendinopathy in shoulder muscles or upper thoracic spine joint pain. Additionally, in a study titled “Entrapment Neuropathies: differential diagnosis and management,” Fisher and Gorelick thought the nerve compression might be an unsuspected component of many cases of shoulder pain. They may notice a soreness developing in their rotator cuff, bicep tendon, or shoulder external rotators and assume the pain is an aggravation of a previous shoulder injury. Injury to the dorsal scapular nerve is usually apparent on inspection when the scapula on the injured side is located farther from the midline than the uninjured scapula. Back and shoulder muscles stabilize and control the scapulae. 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. rfriedberger2 PLUS. Gateways to the posterior scapular region: Dorsal scapular spaces-serves as a pssageway between the anterior and posterior compartments of the arm and between the posterior compartment of the arm and the axilla Boundaries: Superior- teres major Medial-long head triceps Lateral- lateral head tricpes Contents: Propunda brachii artery and vein Radial nerve Suprascapular nerve. Deltoid. After several treatments with massage therapy, Graston technique, or Active Release Technique, the symptoms improve. It is responsible for the innervation of two of the muscles that originate from the scapula, namely the supraspinatus and infraspinatus muscles. It innervates the Supra spinatous muscle and infra spinatus muscles. As the joints lose normal ranges of motion and movements, they begin sending pain signals to the brain which produces mild chronic pain symptoms and further increases scalene, trapezius, and levator muscle spasms. Treatment should always focus on what hurts and restoring it to previous shoulder motions and functional levels, however attention should also be paid to the entire system to prevent shoulder dysfunction and pain. Upper limb anatomy: Scapular Region and Scapulohumeral Group Scapula and Humeral relationship, anatomy, and musculature. Therapy and treatment addresses the overcompensation mechanisms and restores proper neuromuscular control of the scapular and shoulder muscles. The dorsal scapular nerve receives branches from C4 – T1 nerve roots. 6. Test. Oftentimes palpation or compression of the site of nerve entrapment increases radiating pain in the upper arm and forearm. Cervical and thoracic joint pain may be contributing to the development of the neck and back pain. Along this path the nerve supplies small branches to the levator scapulae, rhomboid major, and rhomboid minor muscles. Medial rotation of the arm Additional notes:-• The posterior scapular region also contains part of one additional muscle, the long head of the triceps brachii, which passes between the scapula and the proximal end of the forearm.
