A closed rupture of both flexor tendons of the fifth finger is reported. The most probable cause was an amorphous deposit of calcium hydroxyapatite between the hamulus of the hamate bone and the pisiform bone. The flexor apparatus was reconstructed with a reinforced superficialis flexor tendon from the ring finger.
