A protective device for protecting a proximal interphalangeal joint and a distal interphalangeal joint of a human finger comprises a flexible sheath for wearing around the human finger and at least four motion constraining elements integrated in or secured to the flexible sheath. The motion constraining element is adapted for constraining a lateral and/or rotational deviation motion of a first phalanx with respect to a second phalanx. The motion constraining element covers a lateral side of the flexible sheath at a location corresponding to the joint and is adapted for resisting elongation of the motion constraining element in a longitudinal direction of the flexible sheath. The motion constraining element is bendable in a direction to allow flexion of the joint. The motion constraining elements for the distal interphalangeal joint and for the proximal interphalangeal joint are distinct and separate elements having different points of engagement on the flexible sheath.
