Evaluation of the Treatment of Patients Subjected to Osteogenesis Induced by Tibia Bone Distraction* * Work performed at Hospital Maria Amélia Lins (HMAL), Belo Horizonte, MG, Brazil.

Abstract

Objectives

To evaluate the management of tibial fractures resulting in bone loss (traumatic or infection-related) and the complications occurring during treatment with external fixator and immediately after apparatus removal.

Methods

Forty patients were selected from 2010 to 2017. The mean age of the patients was 33.02 years; 34 subjects were male and 6 were female. All patients had tibial bone regeneration, suffered trauma (mainly related to motorcycle accident) and were followed-up at an outpatient facility.

Results

Proximal tibial bones of up to 17 cm in length and distal tibial bones of up to 14 cm in length were obtained. The largest trifocal transport had the same length as the regenerated bone tissues, which was 14.5 cm. Regarding complications, 29 (72.5%) patients had infections in the pin and wire paths. There were 9 (22.5%) cases of de novo fracture, 6 of which were managed with the implantation of a new circular fixator, and 2 cases of infection of the regenerated bone. On average, patients were subjected to 4.72 procedures (ranging from 2-12), had the fixator for 20.75 months (ranging from 7-55 months), and stayed at the hospital for 53.7 days (ranging from 5-183 days), mainly because of soft-tissue complications, intravenous antibacterial therapy, and even social issues. Two (5%) patients presented symptomatic gonarthrosis, and two other patients had symptomatic ankle arthritis. Three of the patients showed lower limb discrepancy of 3.0, 3.7, and 5.0 cm.

Conclusion

Despite not being widely available, the Ilizarov method is useful for solving the majority of tibial bone losses, regardless of their etiology.
