1. An apparatus for bending the proximal interphalangeal and distal interphalangeal joints of a finger of a human hand, said apparatus comprising:
- a first member having a turned end portion for engaging the metacarpal phalangeal joint of the finger;
a second member movable with respect to said first member for engaging a surface of the finger between the distal interphalangeal joint and the tip of the finger; and
pressure means for exerting pressure against said second member to cause said second member to move toward said first member for bending the proximal interphalangeal and distal interphalangeal joints of the finger between said first and second members, and causing said turned end portion and said second member to retain said apparatus on the hand.

Abstract
An apparatus treats a stiffened joint of at least one finger of the hand and includes a first member for engaging the metacarpal phalangeal joint of the finger and a second member movable with respect to the first member for engaging a surface of the finger on the side of the stiffened joint opposite the metacarpal phalangeal joint. The apparatus further includes at least one threaded member for exerting pressure against the second member for bending the stiffened joint and retaining the apparatus on the hand.

11. An apparatus for bending the proximal interphalangeal and the distal interphalangeal joints of a finger of a human hand, said apparatus comprising:
-
a first member having a first end for engaging the metacarpal phalangeal joint of the finger, said first member also having a second end; a third member extending from said first member second end for confining the proximal interphalangeal joint of the finger between said first and third members; a second member pivotally coupled to and extending from said third member and movable with respect to said first member for engaging the finger between the distal interphalangeal joint and tip of the finger; and pressure means for exerting pressure against said second member and causing said second member to pivot toward said first member for bending the proximal interphalangeal and distal interphalangeal joints of the finger.

12. An apparatus for bending the proximal interphalangeal and the distal interphalangeal joints of a finger of a human hand, said apparatus comprising:
-
a first member having a turned first end for engaging the metacarpal phalangeal joint of the finger, an extension for extending along the finger between the metacarpal phalangeal joint and the proximal interphalangeal joint of the finger, and a second end; a third member having a first end coupled to said second end of said first member and extending from said second end of said first member and forming an angle with said extension of said first member for confining the proximal interphalangeal joint of the finger between said extension of said first member and said third member; hinge means for hingedly coupling said first end of said third member to said second end of said first member; retaining means for maintaining said angle between said extension and said third member; a second member extending from said third member and movable with respect to said first member for engaging a surface of the finger between the distal interphalangeal joint and the tip of the finger; and pressure means for exerting pressure against said second member to cause said second member to move toward said first member for bending the proximal interphalangeal and distal interphalangeal joints of the finger between said first and second members and causing said turned first end and said second member to retain said apparatus on the hand.
