The mechanism of subluxation of the metacarpophalangeal joint is explained on the basis of experimental production of the deformity. A method of treatment is suggested, consisting in restoration of the position of the extensor pollicis longus and adductor pollicis over the metacarpophalangeal joint with transplantation of the extensor indicis proprius to the dorsal apparatus and extensor pollicis longus tendon over the joint.
