Spring metacarpophalangeal flexion splint (knuckle splint)
First Claim
1. A spring metacarpophalangeal flexion splint comprising:
- a cushioned manually bendable proximal phalangeal piece adapted to contact, cover and follow the curve of the proximal interphalangeal joints of the hand;
a palm piece adapted to fit into the palmar arch and palmar crease of the hand and including a substantially rigid tube covered with a pliant cushioning material;
a pair of spaced spring wires, connecting said proximal phalangeal piece and said palm piece and which are disposed generally laterally with respect to the hand and providing spring tension between said proximal phalangeal and palm pieces to force said proximal phalangeal and palm pieces together, each of said spring wires having a projection extending from said palm piece;
strap attachment means on the ends of said projections; and
,an adjustable dorsal strap between said strap attachment means to permit increase and decrease of tension of the spring metacarpophalangeal flexion splint upon the respective tightening and loosening of said strap.

Abstract
A spring metacarpophalangeal flexion splint designed for dynamically flexing the metacarpophalangeal joints without restricting normal hand use includes: a proximal phalangeal piece which is adapted to contact and cover the proximal phalanges of the hand and is formed of a resilient metal strip which is substantially covered with a pliant cushioning material; a palm piece adapted to fit into the palmar arch and crease of the hand and is made up of a rigid tube covered with a pliant cushioning material; and a pair of spaced apart generally parallel spring wires. The spring wires are disposed laterally with respect to the hand and connect the proximal phalangeal piece with the palm piece. A loop extension of the spring wires from the palm piece provides a means of attachment for a dorsal strap which is extended between the wires to permit the increase and decrease of tension on the proximal phalangeal splint upon the respective tightening and loosening of the strap.

11. A spring metacarpophalangeal flexion splint comprising:
-
a manually bendable proximal phalangeal piece adapted to contact, cover, and follow the curve of the proximal interphalangeal joints of the hand, said proximal phalangeal piece comprising a resilient metal strip which is substantially enclosed with a pliant cushioning material; a palm piece adapted to fit into the palmar arch and crease of the hand, said palm piece comprising a substantially rigid tube covered with a pliant cushioning material and a length of spring wire having a bent-over hairpin angle at each end which wire is disposed within said tube with said angles protruding therefrom to act as an attachment means; a pair of spaced spring wires connecting said proximal phalangeal piece and said palm piece and which are disposed generally laterally with respect to the hand, each of said spring wires comprising a length of spring wire attached at one end to said proximal phalangeal piece, the length of wire extending from said proximal phalangeal piece being bent upon itself to form a coil spring spaced from said proximal phalangeal piece and from said palm piece, said wire extending from said coil spring being crimped to form an acute angle spaced from said coil, said acute angle being formed of a downward leg from said coil and an upward leg which is further bent approximately normal to said upward leg to form a loop, said coil angles and loop lying substantially in the same plane, said acute angle being threaded through said bent-over areas of said palm piece wire; the spring wire disposed on the splint which is worn on the ulnar side of the hand being sized slightly shorter and having a slightly smaller coil such that the palm piece is aligned with the palmer crease of the hand and the proximal phalangeal piece is aligned with the proximal interphalangeal joints of the hand; and
,a dorsal strap threaded through said wire loops for increase and decrease of tension of the spring metacarpophalangeal flexion splint upon the respective tightening and loosening of said strap. - View Dependent Claims (12)
