Abstract
An intramedullary nail is disclosed having a tubular elongated body that includes a proximal head portion, an intermediate portion and a distal end portion. The intermediate portion has a longitudinal slot along one side thereof, a groove coextensive with a portion of the slot, and three other grooves spaced about the circumference of the body. This construction provides more desirable flexibility and allows improved revascularization about the nail. The nail is formed of a rod material and the slot and grooves are machined therein to the desired depth and shape.
