Abstract
Abstract An adjustable brace and method for reducing and immobilizing a bone fracture, which includes adjustable pads, and allows the physician to precisely apply pressure in the desired area of the fracture. The preferred brace is particularly designed for immobilizing metacarpal fractures in the hand by applying three point pressure in the area of the metacarpal fracture while allowing essentially full movement of the wrist, hand and fingers. Thus, the hand brace is preferable to conventional casts or splints in allowing more normal movement. Further, the brace is generally radiolucent to more readily monitor the healing of the fracture radiographically. The hand brace preferably includes: a U-shaped bracket with the bight portion fitted in the first web space of the hand; a top, flat, elongated member adjoining the back of the hand; and, a bottom, flat, elongated member received in the palm. A pair of spaced apart pads are positioned in the palm facing the general area of fracture. Another pad is connected to the top member facing the back of the hand in the general area of the fracture. The free ends of the brace are connected by a strap for drawing the members together. The pads are positioned relative each other such that with the strap tightened, three point pressure is applied to reduce and immobilize the fracture.
