Wrist and Hand Joints - Radiocarpal, Intercarpal, CMC, MCP and IP Anatomy

Explore the comprehensive anatomy of wrist and hand joints in this 10-minute educational video that systematically covers every major articulation from the radiocarpal joint to the fingertips. Learn about the radiocarpal joint's ellipsoid structure and its articulation with the scaphoid, lunate, and triquetrum bones, including its supporting ligaments and biaxial movements of flexion, extension, and radial/ulnar deviation. Discover the intercarpal joints between neighboring carpal bones and understand the midcarpal joint's S-shaped composite structure that augments wrist extension. Examine the carpometacarpal joints, particularly focusing on the thumb's unique saddle joint that enables opposition, flexion, extension, abduction, and adduction movements. Study the metacarpophalangeal joints' condyloid structure allowing biaxial movement and circumduction, along with the interphalangeal joints' hinge mechanisms that provide uniaxial flexion and extension. Master the supporting ligamentous structures including collateral ligaments, volar plates, and the deep transverse metacarpal ligament, while exploring additional fascial structures like the palmar aponeurosis and flexor retinaculum. Gain clinical insights into common pathologies such as TFCC injuries, thumb CMC osteoarthritis, ligament sprains, PIP joint instability, volar plate injuries, and gamekeeper's thumb, with practical understanding of joint mechanics during grasp, grip, and fine motor control activities.
