Abstract
An interchangeable orthopedic blade that includes an internal portion and an external portion. The internal portion threads onto either a pre-installed K-wire or a pre-installed screw so as to more accurately place the interchangeable orthopedic blade in, without excessive damage to, the bone when repairing a fracture in the bone, and ultimately providing absolute stable fixation by the interchangeable orthopedic blade holding the fracture in its anatomic position and resisting applied forces while healing, to thereby provide a stable anatomic restoration and eliminate a need for revision surgery due to failure of fixation or malunion. The internal portion is received in the external portion, and rotates relative to the external portion, but has the external portion move non-rotatably axially with the internal portion into the bone as the internal portion threads onto either the pre-installed K-wire or the pre-installed screw.
