Intercarpal and carpometacarpal joints

The joints between the carpal bones (intercarpal and midcarpal), between the carpus and the metacarpals, and between the metacarpal bases. Apart from the thumb, they allow only small gliding movements.

اہم نکات

• Intercarpal, finger CMC, intermetacarpal = plane joints, gliding only.
• Thumb CMC = saddle joint (trapezium–MC1), own cavity.
• Opposition = opponens pollicis at the thumb CMC.
• Midcarpal joint increases wrist flexion.
• Joint: from mesenchyme between bone ends.
• Synovial cavity forms in the middle layer.
• Synovial membrane: type A (phagocytic) + type B (secretory) cells.
• Joint surfaces: hyaline cartilage, no perichondrium.
