Abstract
Abstract An intramedullary splint possesses a longitudinal slot whose opposite edges are formed to engage with the threads of screws securely anywhere along the length of the slot. The splint element is transversely arcuate for engagement inside of the bone canal. The interaction of the screws and slot allow the splint to be drawn up firmly against the concave wall of the bone for greatest support. The placement of metallic parts inside of the bone rather than on the outside reduces interference with muscle attachments and reduces tissue trauma.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
166 words
An intramedullary splint comprising an elongated unitary splint body portion in the form of a plate element which is uniformly arcuate in cross section for ready engagement with the interior surface of the intramedullary cavity and with said body portion adapted to extend on opposite sides of a fracture, said body portion having a longitudinal slot formed therethrough and said slot being continuous along the major portion of the length of said body portion, the opposing longitudinal edges of said slot being parallel and beveled to a uniform V-shaped cross section along the slot in laterally opposed relationship for ready engagement with screws introduced at any desired points along the slot, said longitudinal edges of the slot lying substantially in the concave plane defined by the interior face of the splint body portion, and a relatively short integral screw-threaded extension on one end of the elongated splint body portion for engagement with the intramedullary cavity of a short bone portion on one side of a fracture.
