Abstract
Abstract A hand splint for treatment of arthritic or paralyzed wrists employs a bendable wrist rod covered at a rear portion with hook and loop material. The wrist rod is bent upwardly at about a fifteen degree angle just forward of a front end of a forearm support member in a corrected position. The rod is bent downwardly up to forty-five degrees from normal to accomodate a contorted wrist. The support member is attached to the rear portion of the wrist rod with hook and loop material. Hook and loop material straps retain the patient's forearm within the support member. A front end of the wrist rod is imbedded ina palmar member which is replaceable depending on the need of the patient. An easily removable nut allows the palmar member to be removed from the wrist rod.
