Prostheses, Joint, Wrist, Carpal Scaphoid
Definition : Implantable prostheses designed for replacement of the carpal scaphoid bone, one of the eight bones of the wrist connecting the bones of the forearm and the bones of the hand at the wrist joint. These devices are typically one-piece prostheses made of metal (e.g., titanium) or polymeric (e.g., silicone elastomer) materials, resembling the shape and characteristics of the natural bone; they may include special features (e.g., beaks, holes) to stabilize the carpal bones. The use of these prostheses requires the surgical removal of the scaphoid carpal bone. Carpal scaphoid wrist prostheses are mainly used to restore wrist motion in patients who suffer trauma (e.g., fracture) causing avascular necrosis of the scaphoid bone.
