Instrumentation required to construct CESF frames and hybrid ESF frames is minimal and consists primarily of a wire tensioner and wrenches.

Open and box-end options provide the surgeon flexibility to tighten fasteners, counter torque fixation clamps, and offer more freedom in areas of limited space.

Popular due to ease of use and rapid frame construction. This angled open-back wrench combines the action of a nut driver and box-end wrench in one.

Simplifies relocation or addition of threaded rods. Also used for loosening fasteners on angular hinges and motors prior to steam sterilization.

Utilized to span rings and turn paired nylon nuts simultaneously to achieve compression or distraction. Available in two sizes. Not for use on metal fasteners.

Used to apply tension to small diameter fixation wires. Semi-calibrated for three basic ring diameters.
