ABSTRACT:
An adjustable splint made of silver or gold alloys for stabilizing in extension or realigning the interphalangeal joints of the fingers and thumb consisting of two elliptical rings joined by an elliptical spacer. The individually sized proximal and distal elliptical rings are worn about the fingers on either side of the joint being splinted and disposed at an angle with respect to the axis of the finger. The rings are joined by an elliptical spacer which is placed over the dorsal surface of the joint and sized to distribute and spread the pressure uniformly and comfortably over the surface of the joint. The spacer acts in conjunction with the proximal and distal rings to hold the finger in varying degrees of extension, depending on the adjustment of the splint. The splint may be rotated 90.degree., placing the spacer on the lateral border of a joint to realign an angularly deviated joint.
