Abstract
An interchangeable orthopedic blade including an internal portion and an external portion. The internal portion more accurately places the interchangeable orthopedic blade in, without excessive damage to, a bone when repairing a fracture in the bone and ultimately provide 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. In a first preferred embodiment, the internal portion is a screw with an externally threaded head. In a second preferred embodiment, the internal portion is an externally threaded set screw.
