In this podcast. Dr. Larry Hurst takes you through Osteoarthritis of the Carpometacarpal (CMC) joint of the thumb.

Osteoarthritis of the CMC joint of the thumb is characterized by articular degeneration owing to compression and rotational shear forces on the trapezium. As the disease progresses, the thumb metacarpal may become dorsoradially subluxated on the trapezium, resulting in hyperextension deformity of the metacarpophalangeal (MP) joint. The thumb CMC joint is the most frequently affected joint of the hand to develop localized osteoarthritis.
