Extension Mechanism of the Proximal Interphalangeal Joint of the Human Phalanx: A Cadaveric Biomechanical Study

<div>Experiment with metacarpophalangeal (MP) joint with 0 degree (a). The MP joint angle can be changed freely while the structures distal to the MP joint are keeping their position (b). FDS: flexor digitorum superficialis; MC: metacarpal; P1: proximal phalanx; P2: middle phalanx.</div>
