A good physiotherapy program is crucial for the success of an external fixation operation. It will help to maximize the effectiveness of the procedure and ensure full function of the leg after fracture. The procedure is not a cure-all and requires a period of recovery, usually six months or longer, and is performed under a doctor's supervision.

The procedure uses Kirschner wires or pins to fix the bones in the skeleton. These pins are connected to a connecting ring or bar by bolts. The fixing bar can be a single piece or a combination of two connecting bars. The fixator frame may be circular or linear.

Another factor in the SK external fixation operation specification is wire stiffness. The wire used is made from Ti-6Al-4V. Its stiffness exceeds 3 times the body weight, so more than one wire is used in parallel. This method helps to share the load between the wires.

Surgical pins that contact the body tissue are made from metal, and the materials are generally of medical grade. They may be made of CoCrMo, Ti6Al4V, or 316 LVM stainless steel. The pins should be tested according to ISO 10993 for biocompatibility. The newer devices should undergo bench testing and rigidity tests in animal models.

A number of other factors are involved in a successful external fixation operation. The external fixator must be able to distribute the forces applied to it. This means that it should not cause any friction between the bone and the fixator.
