Abstract
The present invention relates to an intramedullary nail for proximal femoral fractures. The intramedullary nail comprises an elongate body () with a longitudinal bore (). The elongate body () includes a proximal portion () with an oblique transverse bore () for a proximal locking member and a distal portion () with at least one transverse bore () for a distal locking member. An inlet end of the oblique transverse bore () is configured as a recess () with a recessed surface (). The recessed surface () is composed of recessed lateral surface portions () and a recessed proximal as well as a recessed distal surface portion (andrespectively). Each of the recessed lateral surface portions () is configured with at least one protuberance () for preventing or reducing the risk for misalignment of e.g. a reamer and, if misalignment occurs, this will not affect critical parts of the intramedullary nail.
