Use of the Ilizarov external fixator in the treatment of patients with Ollier's disease.

The authors present the results of treatment of 10 patients with Ollier’s disease using the Ilizarov technique. The Ilizarov device was used to treat leg length discrepancy and to enhance the conversion of chondroma cartilage into normal mature bone, with no curettage and bone grafting. The mean duration of treatment was 9.4 months. This technique was highly efficient in treating the disease. It led to conversion of the abnormal cartilage into histologically mature bone in all patients. Some complications were seen, such as decreased knee mobility, which required prolonged use of the device. The Ilizarov technique is successful in treating patients with Ollier’s disease despite some complications and the difficulty in using the technique.

Evaluation of effectiveness of 10% polyvinylpyrrolidone-iodine solution against infections in wire and pin holes for Ilizarov external fixators

CONTEXT AND OBJECTIVE Superficial infection at wire and pin insertions in the skin is a frequent disorder among patients utilizing the Ilizarov method. The objective of this study was to evaluate the effectiveness of daily topical application of 10% polyvinylpyrrolidone-iodine solution against infections of the holes for Kirschner wires and Schanz pins among patients using Ilizarov external fixators, in comparison with cleaning these holes only with 0.9% sterile physiological saline solution. DESIGN AND SETTING Controlled randomized clinical trial, in the Orthopedics and Traumatology Outpatient Clinic, Hospital São Paulo, and Orthopedics and Traumatology Center of Jundiaí. METHODS 30 patients were treated using the Ilizarov technique: 15 were instructed to apply 0.9% physiological saline dressing on the wire and pin insertions and 15 to apply 0.9% physiological saline plus 10% polyvinylpyrrolidone-iodine. Patients were evaluated at outpatient return visits for identification of signs and symptoms of superficial infection at wire and pin insertion sites. Samples were collected from cases of purulent exudate secretion, for culturing and clinical tests. RESULTS The chi-squared and Fischer exact tests were applied, but no statistically significant association between the intervention of topical polyvinylpyrrolidone-iodine solution and the prevention of infections at wire and pin insertions could be found. CONCLUSIONS Topical 10% polyvinylpyrrolidone-iodine solution applied daily to Kirschner wire and Schanz pin insertions did not reduce the incidence of superficial infection at these holes, in comparison with mechanical removal of dirt using 0.9% physiological saline solution.

Artrodese subtalar do pé pelo método de Ilizarov

There had been heated 28 patients in a total of 29 feet, with na age average of 25,8, predominance in the quality of being male 16 patients (57,2%), white color 25 patients (89,2%), right side 16 patients (57,2%). As the ethiology there were a predominancy of the calcaneum fracture´s consequence 11 patients (37,9%) and poliomyelitis 11 patients (6,9%), bone bar 2 patients (6,9%), primary arthrosis 02 patients (6,9%) abd cerebral palsy 1 patient (3,5%). The average time of consolidation was 3,5 months. There had been used bone graft in 11 patients (44%). There were the necessity to promote the calcaneum extension to raise the pitch of itself, in 2 cases (6,9%). The mounting is simple and it relies on 2 rings transbone settlement through 2 strings fixed in the talus and 2 in the calcaneum. As the result was obtained in 100% of consolidation, pain´s absence and osteopethosis and feet´s great sensibility. In the complications there were found, besides the usual or method itself 1 (3,5%) patient. Showed deep infection in 1 of the strings. The method has showed efficient, independent of the ethiology with 100% of consolidation beyond to permit a certain independancy of the patient during the treatment.
