The role of ring external fixation in Charcot foot arthropathy.

Abstract：

:These two morbidly obese patients with severe Charcot foot arthropathy were treated successfully with percutaneous correction of their deformity followed by a stepwise application of a pre-assembled neutrally aligned multiplane ring external fixator. This technique transfers well to the trauma environment in which alignment can be maintained without further violation within the zone of injury. The application of the fine wire ring external fixation has been used for many years to accomplished leg lengthening and correction of deformity. Historically it has required a great deal of experience to apply to complex frames and implement the required daily adjustments. The patient experience often has been an unpleasant ordeal with a high potential for associated morbidity. This negative exposure has prompted practicing orthopedic surgeons to avoid this technique, feeling that it best be left to those in tertiary care setting who are equipped to handle the morbidity and complications. Taking this technology from the domain of the deformity surgeon to the general orthopedic community will require the suppression of bad memories from residency. Using the device solely as a method of maintaining alignment eliminates many of the dynamic attributes that contributes to pain and morbidity. The bone and soft tissues are not stretched, eliminating much of the pain and decreasing the rate of traction-associated pin tract morbidity. Because there is no dynamic of the treatment, the simplified frame can be pre-assembled and have no adjustable components. The experience derived from this application has the potential of expanding the role of ring external fixation. Where the ring has been used previously as method of both obtaining and maintaining alignment, this application uses a simplified neutral version of a complex device to simply maintain alignment in a high risk patient population. Correction of deformity and achieving alignment/reduction of fractures is well within the domain of practicing orthopedic surgeon. Once that correction has been achieved, this application simply maintains that correction. It helps avoid extensive surgical dissection in a poor host and eliminates the need for bone that is mechanically capable of holding internal fixation devices during the bony and soft tissue healing period.
