Correction of complex lower limb deformities by the Ilizarov technique: An audit of complications.

This is an audit of complications resulting from correction of complex lower limb deformities by the Ilizarov technique. 33 patients (40 bone segments) were reviewed and divided into 4 groups according to the type of surgery carried out: limb lengthening and/or correction of deformity, bone or joint stabilisation, treatment of nonunion or bone defect, angular and/ or rotation correction. Most minor complications were fixator specific. Pin tract infections were almost universal but responded well to oral antibiotics and rarely resulted in osteomyelitis. Major complications were procedure specific and more common in those patients who underwent leg lengthening, treatment for nonunion and bone transport. There was also a high incidence of nerve injury as a result of acute angular deformity correction. Despite the high complication rate the Ilizarov technique remains an effective tool for complex lower limb reconstruction surgery.
