ABSTRACT:
An elliptical finger ring splint comprising two elliptically shaped rings joined at an apex which, when worn, is positioned directly beneath a finger joint when the palm is turned downwards. The tops of the rings are spread such that the planes of the rings form a V, with the top of one ring impinging upon the top of the more distal phalanx of the finger, and the top of the other ring impinging upon the top of the more proximal phalanx, when the finger is fully extended without hyperextension. The rings are made of a rigid but slightly deformable material which in the preferred embodiment is silver or gold to give an attractive appearance while retaining and enhancing the therapeutic orthotic values. The elliptical shapes permit the apex to be positioned directly beneath the finger joint with the rings canted at approximately a 45.degree. angle to the axis of the finger thus impinging upon the tops of the adjacent phalanges urging the finger towards flexion and inhibiting hyperextension. The rings are sized for each individual phalanx to provide lateral stability during all degrees of flexion and extension. They are joined in such a fashion that the apex is slightly deformable thus permitting adjustment of the angle between the planes of the rings for variations in finger size and comfort.
