From brachial plexus, around humeral head, through the quadrilateral space to deltoid/teres minor, Humeral head compresses nerve during extreme abduction, C5 to C7 merge, travel between clavicle and first rib through axilla to serratus anterior muscle, Brachial plexus down anterior arm, at antecubital fossa passes through radial tunnel, dives between two heads of pronator muscle, under flexor digitorum superficialis, through carpal tunnel, C5 to C7 merge into lateral cord brachial plexus, goes through axilla, under coracobrachialis, through biceps and under deep fascia at the elbow, From brachial plexus, through axilla, down posterior arm until it circles toward anterior arm at spiral groove of the humerus; down anterior arm and enters radial tunnel just above the lateral epicondyle, Injury in axilla or proximal humerus (fracture), Emerges through sternocleidomastoid muscle, across posterior neck, dives under trapezius, Very superficial course in posterior neck and directly under the trapezius muscle, From upper trunk brachial plexus, through posterior triangle, across top of scapula and through scapular notch, down posterior aspect scapula and across scapular spine to supraspinatus, infraspinatus, Entrapment under transverse scapular ligament that covers the suprascapular notch, From brachial plexus down anterior arm; just above medial epicondyle it passes to the posterior compartment and into the cubital tunnel; down ulnar side of forearm into Guyon canal (boundaries are hamate and pisiform bones); splits into deep (motor) and superficial (sensory) branches in canal, Motor: no loss or weak thumb adduction, weak digit abduction, and adduction toward center of long digit, Nerve roots C5 and C6 as they exit vertebral foramina and form upper trunk brachial plexus, Motor: infraspinatus, supraspinatus, biceps, and deltoid, No protective coverings (epineurium and perineurium) on the nerves after they exit the foramina, Shoulder dislocation; look for radial nerve injury, Sagging shoulder suggests spinal accessory nerve injury, Acromioclavicular and sternoclavicular joints, Muscle tenderness, integrity, or deformity, Forward flexion 180 degrees; extension 45 degrees; lateral abduction 180 degrees; adduction 45 degrees; internal rotation 55 degrees; external rotation 40 degrees, If active range of motion is normal, no need to test passive range of motion;

oblique coronal view for suprascapular notch, axial view for spinoglenoid notch; also evaluates for rotator cuff pathology, Useful if diagnosis unclear or recovery not following expected clinical course, Useful for evaluation of suspected paralabral cyst or labral pathology; oblique sagittal view of shoulder shows nerve at inferior rim of the glenoid; MRI less useful for evaluation of quadrilateral space because it is a dynamic entity, Axial images of carpal tunnel evaluates for hypertrophy of synovium, space-occupying lesions (ganglion cyst), Axial images at elbow show mass effect from enlarged bicipitoradial bursa, hypertrophy of extensor carpi radialis brevis muscle, or vascular pathology, Axial images can evaluate the cubital tunnel for nerve subluxation, arcuate ligament pathology; may need views of elbow in flexion and extension if subluxation suspected, Imaging of nerve itself not usually useful, but can sometimes show denervation changes of supraspinatus and infraspinatus muscles, Shoulder range-of-motion exercises, including posterior capsule stretching; avoid heavy lifting, Consider baseline nerve conduction studies at one month, repeat at three months, Activity modification, splints worn at night, Consider nerve conduction studies if no improvement within four to six weeks, Pad external elbow against external compression; decrease repetitive elbow flexion, Conservative therapy only for sensory symptoms, Cock-up splint to assist weakened wrist muscles, Consider surgery sooner if late presentation with severe weakness or atrophy, progressive weakness, Shoulder range-of-motion exercises to prevent contracture, Nine to 12 months is average recovery time; consider conservative treatment for up to 24 months, Activity modification; consider single steroid injection, Physical therapy for extensor-supinator muscle group, Three months of physical therapy before consideration of surgery (unless intractable pain), Consider surgical decompression for intractable pain, although no available evidence from randomized controlled trials, Physical therapy to maintain full shoulder range of motion and strengthen other shoulder (compensatory) muscles, Early magnetic resonance imaging (at one month) to rule out anatomic lesion (i.e., ganglion cyst), Pad volar wrist area; activity modification. Electrodiagnostic testing can be useful and quantitates severity of entrapment, although false negatives and false positives may occur.16,17. In the anatomical snuffbox, the radial artery is closely related (<2mm) with the superficial branch of radial nerve near the styloid process of radius in 48%, while in 24% the radial artery is closely related to the lateral cutaneous nerve of forearm.
