The user-friendly design of the SK® single clamp allows for pre-drilling as well as placement of positive thread pins through the pin-gripping bolt. This eliminates the difficulty historically associated with the use of positive-profile threaded pins.

Isolated connecting rod testing does not tell the entire story. Actual testing of ESF frame models confirms that frame simplification can be accomplished by incorporating strong connecting rods. Typical ESF frames were constructed of large SK® components with medium pins as well as medium KE components with medium pins.

For many years, external fixation pin use centered around the Kirschner-Ehmer (KE) external fixation device and newer modifications of it. This resulted in potentially confusing pin terminology that is poorly suited to the use of improved external fixation devices such as the IMEX® SK® external fixator.

The most powerful way to simplify the ESF method lies in mechanical frame improvements that are not dependent on full-pins or complex frame geometries. In this respect, the SK® ESF System is designed to be dramatically different from the KE and new KE-like systems that utilize traditional 1/8” and 3/16” connecting rods.

Hybrid external skeletal fixation (HESF) is rapidly becoming recognized as a very valuable tool for repair of fractures with a short distal or proximal segment.
