Treatment of Infected Pseudarthrosis of the Tibia Using the Ilizarov Method and the Orr Dressing.

ABSTRACT

Objective This study aims to analyze outcomes and clinical and epidemiological data of infected tibial pseudarthrosis using the Ilizarov method and the Orr dressing. Methods Data from n = 43 patients diagnosed with infected tibial pseudarthrosis were analyzed by descriptive and inferential statistical methods. In addition, Paley's assessment criteria evaluated bone and functional outcomes. Qualitative variables were presented as the distribution of absolute and relative frequencies. The presentation of quantitative variables followed the D'Agostino-Pearson test. Results Thirty-seven (86.04%) subjects were males, and six (13.95%) were females. The most frequent age group among patients was 50 to 59 years old (25.6%), with a p-value = 0.8610. The treatment time was longer for the trifocal treatment (23.8 months) when compared to the bifocal treatment (15.6 months), with a p-value = 0.0010* (highly significant). Excellent bone outcomes represented 72.09% of the sample; 23.25% of outcomes were good. Functional outcomes were excellent in 55.81%, good in 6.97%, and regular in 27.90% of subjects. The Orr dressing (using Vaseline gauze) proved effective, achieving wound healing with soft tissue coverage in all patients evaluated. Conclusions The Ilizarov method resulted in a substantial change in the treatment of bone infections, especially infected pseudarthrosis. The versatility of this method has turned it into an effective tool, allowing the healing of the infectious process and the correction of potential deformities and shortening.
