@anatomytv: CARPAL TUNNEL SYNDROME EXPLAINED ‼️‼️‼️‼️ Carpal Tunnel Syndrome is a compressive neuropathy of the median nerve at the wrist as it passes through the carpal tunnel. It is the most common peripheral nerve entrapment syndrome.‼️‼️ Contents of the Tunnel: • Median nerve • 9 tendons: • 4 flexor digitorum profundus • 4 flexor digitorum superficialis • 1 flexor pollicis longus ‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️ Pathophysiology • The syndrome results from increased pressure within the carpal tunnel. • This pressure causes ischemia and mechanical compression of the median nerve. • Common causes: • Repetitive wrist/hand movements (occupational or sport-related) • Inflammatory conditions (e.g. rheumatoid arthritis) • Fluid retention (e.g. pregnancy) • Diabetes mellitus • Hypothyroidism • Space-occupying lesions (tumors, ganglion cysts) ‼️‼️‼️‼️‼️‼️‼️‼️ Sensory symptoms (initially more prominent): • Numbness and tingling in median nerve distribution: thumb, index, middle, and lateral half of ring finger. • No symptoms over the thenar eminence (due to palmar cutaneous branch of median nerve). • Motor symptoms (in chronic/severe cases): • Weakness or atrophy of the thenar muscles (especially abductor pollicis brevis) • Difficulty with fine motor tasks (e.g., buttoning, gripping) • Symptom patterns: • Worse at night • Aggravated by activities involving wrist flexion or extension • Relieved by shaking the hand (“flick sign”) ‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️ save this for your next study day 📖 follow for more anatomy tips 😃 #anatomy #carpaltunnel #3danatomy #anatomyandphysiology #LearnOnTikTok #anatomyclass #nerve #physiotherapy
