[Complex reconstruction in Charcot arthropathy using the Ilizarov ring fixator]

From the foot surgeon's point of view, the surgical treatment of Charcot neuro-osteopathy is considered challenging. Conservative treatment using plaster and orthoses is used to treat Charcot arthropathy, especially in the acute stage of a treatment strategy. Surgical treatment using the Ilizarov ring fixator is established for the correction of residual misalignments and also in the acute stage. Advantages of the ring fixator are great stability of the apparatus, low loading of the soft tissues caused by foreign material, and possible long-term treatment.

The aim of this work is to explain the indication, planning of correction, assembly of Ilizarov ring fixator, and the postoperative treatment with respect to the literature and the authors' experience. The aim of treatment with the Ilizarov ring fixator is a plantigrade, resilient, ulcer-free foot. Treatment is lengthy for both the affected patients and the attending orthopedic surgeon, and great attention is required to achieve the desired corrections and a good result for the patient.

According to the literature and the authors' experience, the results indicate that the Ilizarov ring fixator represents a viable method for the preservation of the affected limb in patients with Charcot neuro-osteopathy. The assembly of the apparatus must follow the principles of Ilizarov in order to avoid failure. Corrective osseous and soft tissue interventions require a detailed preoperative analysis.
