Abstract: An orthopedic forearm splint intended to limit dorsiflexion of the wrist, without interfering with volarflexion and use of the hand, whereby ganglions of the wrist may be caused to regress. Applies the inventor's discovery that extreme dorsiflexion is the causative or aggravating factor in wrist ganglion. Comprises a light cantilever splint secured to the dorsum of the arm by one bracelet, with the distal end elongated beyond the bracelet in cantilever fashion past the wrist and freely apposing the hand, whereby it will strike the back of the hand if dorsiflexion is attempted, but does not interfere with volarflexion or normal work. Reversible to dodge ganglions and prevent chafing.
