A bone fixator as disclosed herein includes at least one removable portion, and is particularly suitable for external fixation of the bones of the femur and tibia (knee joint), the tibia to the foot (ankle joint), the lower leg, the lower thigh, or the forearm and hand. Embodiments allow multiaxial, multiplanar movement, as well as procurvatum and recurvatum, on the anatomy to achieve optimal placement. Embodiments of the fixator includes four fixator joints, each of which is articulating with multiple degrees of freedom. Some fixator joint(s) include a linkage bar connectable to a multi-pin clamp having a quick connect mechanism. The multi-pin clamp is configured for fixation to a bone. Other fixator joint(s) may be connected to the multi-pin clamp in a semi-permanent or non-detachable manner. A telescoping rod assembly allows adjustment of the length of the fixator by a single individual.

Bone fixator with removable portion

A bone fixation system includes a fixation plate formed of a fiber reinforced polymer composite material with a plurality of apertures configured to receive screws for fracture fixation. An malleable metallic insert is disposed within each aperture. The inserts may be sized to accept locking or non-locking screws over a range of angles. The inserts may protrude through the plate on the bone side, providing clearance between the composite plate and the bone. The apertures and inserts may have a generally cylindrical or obround shape. In embodiments, the inserts are shaped complementary to the apertures in which they are disposed.
