We carried out a systematic review of the literature
to evaluate the evidence regarding the clinical results of the Ilizarov
method in the treatment of long bone defects of the lower limbs. Only 37 reports (three non-randomised comparative studies, one
prospective study and 33 case-series) met our inclusion criteria.
Although several studies were unsatisfactory in terms of statistical
heterogeneity, our analysis appears to show that the Ilizarov method
of distraction osteogenesis significantly reduced the risk of deep
infection in infected osseous lesions (risk ratio 0.14 (95% confidence
interval (CI) 0.10 to 0.20), p <
0.001). However, there was a
rate of re-fracture of 5% (95% CI 3 to 7), with a rate of neurovascular
complications of 2.2% (95% CI 0.3 to 4) and an amputation rate of
2.9% (95% CI 1.4 to 4.4).The data was generally not statistically
heterogeneous. Where tibial defects were >
8 cm, the risk of re-fracture
increased (odds ratio 3.7 (95% CI 1.1 to 12.5), p = 0.036). The technique is demanding for patients, illustrated by the voluntary
amputation rate of 1.6% (95% CI 0 to 3.1), which underlines the
need for careful patient selection. Cite this article:
