<p>A prosthetic nail for stabilizing fractures in a humer has an elongated slightly twisted shape and tapers substantially over its entire length from a relatively thick head to a relatively thin tip. The elevational configuration of the nail has a thin elongated generally twisted midportion with two curved ends, a larger head end and a thinner tip end. The plan configuration of the nail tapers from the head to a blunt rounded tip. Two holes for retaining screws are provided through the head end either at right angles to the elevational length of the nail or at a slight inward inclination thereto. The retaining screws have a broad shank and are threaded for retention in the bone.</p> |
