The invention relates to a DMLS orthopedic intramedullary device and a method of manufacturing same. The orthopedic device, such as an intramedullary nail, for internal fixation of a bone and a method of manufacturing the same. The orthopedic device may be formed from a medical grade powder via an additive manufacturing process. The forming process may include heat treating the additive manufactured component and machining the heat treated additive manufactured component to form the orthopedic device. Further, the orthopedic device may be formed to include an internal sensor probe channel that extends within at least a portion of the wall of the device, but which does not protrude through an outer portion of the wall. Embodiments further include a dynamizing intramedullary nail that accommodates adjustments in the relative axial positions of one or more sections of the orthopedic device. The device may include features in an inner region of the orthopedic device that may alter an elastic modulus of the orthop
