RESUMO
Poliomyelitis is an infectious disease caused by a neurotrophic virus targeting anterior horn cells of lower motor neurons resulting in flaccid paralysis and represents a common condition in developing countries, and even nowadays, most of both treated and untreated cases result in foot deformities. Between 1994 and 2007, 27 patients were treated by classic ring Ilizarov fixator, aiming at producing a stable plantigrade and cosmetically acceptable foot and followed up for meanly 7.17 years. Additional procedures were performed if needed. The mean time in frame was 4.2 months. All the patients were satisfied with their gait, compared to preoperative status. A painless and plantigrade foot was obtained in all patients, and limb-length discrepancy was always corrected where present. No major complications were encountered. In conclusion, the Ilizarov method allows simultaneous progressive correction of all components of severe foot deformities associated with limb-lengthening discrepancy with minimal surgery, reducing risks of cutaneous or neurovascular complications and avoiding important shortening of the foot.
