Abstract
A nail fixation system and method for the fixation of fractures of the distal radius. The system has a nail inserter and a plurality of arcuate nails, each nail having a head end and a pointed end. Each nail is secured by its head end in the nail inserter and fed through one of several holes cut into the distal radius proximal to the fracture. The curvature of each nail and the angulation of each hole allows each nail to travel through the medullary canal of the radius and then have its point be positioned in a specific site internally on the distal epiphysis. Once the distal radius is fixed the entire wrist is placed in a cast for several weeks until the radius is healed sufficiently for the removal of the nails.
Claims11
A bone fixation system, comprising:
- first, second, third, and fourth nails, each nail having a headless first end, a pointed second end, and a shank, the shank having an elongated straight section extending from the headless first end, a short straight end section terminating in the pointed second end, and an arcuate section therebetween, the arcuate section of the first, second, third and fourth nails each having a radius of curvature, the radius of curvature progressively increasing from the first nail to the fourth nail;
- and
- a nail inserter having a cylindrical body and a compression nut, the body having a nail insertion end and a grip end, and the compression nut being rotatably attachable to the grip end and thereby being capable of compressing said grip end in order to clamp the first end of said first, second, third and fourth nails.
