InSafeLOCK Humerus Nail is an innovative intramedullary nail system developed for ease of application. While it enables locking with the help of an internally safe locking pin (Endopin) in the distal, it provides multiple proximal locking and compression in different planes with the static transverse, static angled, dynamic compression locking holes, and screw application options through the calcar angled hole in the proximal.
