Abstract
An 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 accommodate adjustments in the relative axial positions of one or more sections of the orthopedic device. The devise may include features in an inner region of the orthopedic device that may alter an elastic modulus of the orthopedic device.

22. An intramedullary nail, comprising:
-
a wall comprising one or more laser sintered layers of a medical grade powder, the wall having an outer portion and an inner portion, the inner portion generally defining an inner region of the intramedullary nail; and an internal sensor probe channel that extends into at least a portion of the wall, the internal sensor probe channel not extending through the outer portion of the wall. - View Dependent Claims (23, 24, 25, 26, 27)

28. An intramedullary nail, comprising:
-
a first section coupled to a second section by a telescopic portion, the telescopic portion having an outer diameter sized to be slidingly received in an inner region of at least one of the first and second sections to accommodate adjustments in a relative axial position of the first and second sections, the first and second sections structured for implantation into a bone; and an actuator adapted to provide a biasing force to bias the relative axial positions of the first and second sections. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)

47. The intramedullary nail, comprising:
-
a wall having an outer portion and an inner portion, the inner portion generally defining an inner region of the intramedullary nail; a first screw hole and a second screw hole, the first and second screw holes extending through at least the outer portion of the wall; and one or more protrusions in the wall between the first and second screw holes, the one or more protrusions not extending through the outer portion of the wall, the one or more protrusions structured to selectively alter an elastic modulus of the intramedullary nail. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55)

56. The intramedullary nail, comprising:
-
a first section having a wall, the wall generally defining an inner region of the first section; and a second section coupled to an inner section, the inner section sized for lateral displacement in at least a portion of the inner region of the first section, the inner section being selectively detachable from the first section by a locking screw to alter an elastic modulus of the intramedullary nail. - View Dependent Claims (57)
