Abstract: The present disclosure provides an intramedullary nail assembly comprising an intramedullary nail and an insert sleeve. The intramedullary nail has a nail longitudinal axis and comprises a cavity being accessible from a nail proximal end, the cavity being confined by a nail inner wall, the cavity having a cavity longitudinal axis. The nail inner wall is provided with a predominantly longitudinal groove and a predominantly transverse groove, the transverse groove and the longitudinal groove communicating with each other at a junction. The insert sleeve is configured to be received within the cavity and comprises a cam radially protruding from the insert sleeve and sized to mate with each of the longitudinal and transverse grooves such that the cam is displaceable within the longitudinal groove from a longitudinal groove proximal end to the junction and is further displaceable towards a terminal end of the transverse groove.

Abstract: The present invention provides an intramedullary nail having a body with a transverse bore extending through the body and having an area of enhanced stress distribution on at least the lateral side of the transverse bore. In one exemplary embodiment, the intramedullary nail includes a cutout adjacent to the transverse bore, such as an oblique cutout, that enhances the stress distribution of the intramedullary nail in the region around the lateral opening of the transverse bore. In one exemplary embodiment, the cutout includes a ramp portion or area that defines the lateral opening of the transverse bore. In other exemplary embodiments, the cutout includes a runout or a substantially flat portion that defines the lateral opening of the transverse bore.
