ABSTRACT:
The present invention sets forth a cover for orthopedic splinting rods which in its broadest sense consists of a single sheet of material which is formed into a cylinder having a longitudinal slit up its side and a curved top of the cap to allow for natural resilience of the cap to hold the walls of the cap against the edges of the ends of the splinting rods to insure retention of the cap on the ends of the splinting rods. An embodiment for external use encases the metal cap in a plastic housing having a gripping means to assist in the installation of the cap on the ends of the splinting rod. The external housing has smooth surfaces to avoid and minimize any trauma to surrounding body tissue. The present invention also sets forth a method of installing a cover for orthopedic splinting rods on the clipped end of the rod, comprising the steps of rotating of the metal cap down over the burred end of the clipped splinting rods and rotating the cap to cause the burred end of the cap to form a helical groove or type of screw thread in the wall of the cap to secure the cap. The cap tapers at the end near the top so as to cause ever increasing pressure on the burred end of the splinting rod as it is advanced into the cap.
