Well explained, systematically outlining the anatomical causes of hand numbness, providing more diagnostic alternatives
[[Thoracic Outlet Syndrome|Anterior Scalene Syndrome]]
- Main: Compression in the scalene triangle affecting nerves and blood vessels within the interscalene space
- The anterior scalene mainly attaches to the anterior tubercles of the transverse processes of the 3rd, 4th, 5th, and 6th cervical vertebrae, with some attachments to the posterior tubercles of the 3rd and 4th cervical vertebrae. After injury, local inflammation and edema compress the 5th cervical nerve, which innervates the dorsal scapular nerve, potentially causing pain in the rhomboid area, distinguishable from rhomboid muscle strain
[[Pronator Teres]]
Over-contraction compressing the median nerve
Pain in the median nerve distribution of the forearm (radial side of the 3 fingers), tenderness/hardening of the pronator teres
Commonly occurs with frequent pronation (e.g., carrying a bag on the forearm)
[[Supinator]]
Compression of the deep branch of the radial nerve (muscular branch, not sensory branch)
Typically causes extensor weakness without sensory deficits; if numbness occurs, it indicates involvement of the superficial branch of the radial nerve
[[Carpal Tunnel Syndrome]]
