Study Notes
High Median Nerve Palsy Patho-mechanics
- Thumb is adducted due to ulnar innervated adductor pollicis and deep head of flexor pollicis brevis
- Index finger is flexed at metacarpophalangeal (MCP) joint due to intact interosseous muscles
- Minimal flexion is seen in the interphalangeal (IP) joint
- Middle finger is in complete flexion
Hand Posture in High Median Nerve Palsy
- Medial view of the hand shows the characteristic posture
