Thumb kinematics and their relevance to function.
With its sophisticated motion and prehensile ability, the TM joint is essential to hand function. The bony anatomy and the musculotendinous forces across the joint allow this advanced function. The elaborate ligamentous system provides stability. The high forces transmitted during routine pinch and grasp would not be possible without this complex arrangement.
