Document Summary
0 - no whiplash - don"t treat as whiplash duh. Torticollis - two types - congenital and acquired. If contracted on left - rotated to the right and laterally bent to. Group of conditions that cause neurovascular compression - subclavian vessels, brachial plexus in region of clavicle, first rib and anterior scalene and pec minor. Symptoms - tingling, numbness, pain, paresthesia - only some feeling, Compressed vein - interstitial swelling, heat in arm. Compress artery - paleness, cyanosis, capillary refill, trophic changes - nutritional changes to tissues (eg - brittle/pitted nails, skin is dry/cracking). Displaced clavicle can cause compression, bone repair may cause temporary compression. Radial nerve - c5-t1 innervates extensors (anconeus, triceps) Ulnar nerve c7 - t1 (intrinsic muscles of the hand) Intrascalene space - between middle and anterior scalenes. No vascular compression w respect to the vein. Swelling in arm wouldn"t be sign because no venous compression, but autonomic could still be responsible.
