ORTHO 1
A device having a hollow core; for example, an instrument with a central channel that can be fitted over a guide wire or pin.
Cannulated
Fin-shaped rasps used to enlarge the medullary canal for the insertion of an implant.
Broach
Spongy or trabecular bone, softer of the two types of bones.
Cancellous Bone
A Fracture in which there are multiple bone fragments
Comminuted
Compacted bone, the denser of the two types
Cortical Bone
Alignment of bone fragments into anatomical position by manipulation or traction of the limb.
Closed Reduction
To impact or press a joint implant into position. DO NOT REQUIRE BONE CEMENT
Press-Fit
Areas of attachment for tendons and ligaments or provide a passageway for nerves and blood vessels.
Landmarks
Mechanical Force in which a structure is pressed together
Compression

Open Reduction
ORIF
Open Reduction Internal Fixation
Surgical Repair of a Fx by implanting a device such as a metal plate, rod, or nail that holds the bone fragments in correct position during healing.
Internal Fixation
A mechanical method of applying force to a fractured bone in order to bring the fragments into alignment.
Traction
A method of immobilizing a limb, can be fully or partially circumferential.
