Neurovascular (Nerves, Arteries, Veins Relations) of the Scapular

Here's a comprehensive overview of the neurovascular relations of the scapula: Nerves: 1. Suprascapular nerve (C5-C6): passes through suprascapular notch, innervating supraspinatus and infraspinatus muscles. 2. Long thoracic nerve (C5-C7): runs along anterior scapular surface, innervating serratus anterior muscle. 3. Spinal accessory nerve (CN XI): passes through scapular region, innervating trapezius and sternocleidomastoid muscles. 4. Axillary nerve (C5-C6): runs near scapular neck, innervating deltoid and teres minor muscles. Arteries: 1. Subclavian artery: gives rise to branches supplying scapular region. 2. Axillary artery: supplies blood to scapular muscles and surrounding tissues. 3. Suprascapular artery: branches from thyrocervical trunk, supplying supraspinatus and infraspinatus muscles. 4. Transverse cervical artery: supplies blood to scapular region. Veins: 1. Subclavian vein: receives blood from scapular region. 2. Axillary vein: drains blood from scapular muscles and surrounding tissues. 3. Suprascapular vein: accompanies suprascapular artery. Clinical Significance: 1. Scapular fractures or trauma can compromise neurovascular structures. 2. Thoracic outlet syndrome: compression of subclavian artery and vein, and brachial plexus nerves. 3. Winged scapula: weakness or paralysis of serratus anterior muscle due to long thoracic nerve damage. Anatomical Variations: 1. Variation in suprascapular notch shape and size. 2. Anomalous courses of nerves and vessels. Surgical Considerations: 1. Scapular fracture management. 2. Thoracic outlet syndrome decompression. 3. Nerve repair or reconstruction. Clinical Examination: 1. Palpation of scapular region. 2. Muscle strength testing. 3. Sensory examination. 4. Imaging studies (X-ray, CT, MRI). #Scapula
