Objective: To evaluate the clinical effect of the Ilizarov compress distract device. Method: 62 patients were treated with Ilizarov technique. Among these cases, 25 were chronic osteomyelities, 13 were bone non union, 12 were extremity fracture, 3 were club foot, 4 were genual varum, 3 were cubitus valgus, 2 were congenital pseudoarthrosis of tibia, and follow up for 0.5～3 years. The lengthening ranged from 2 cm to 9 cm. Result: All patients got primary union; after six months the fracture were all union; there were no non union. Conclusion: It's a better choice to use Ilizarov compress distraction device to treat osteomyelities, bone defect, bone non union, especially for those combined with length discrepancy of the extremity. This technique also can be used in cases of soft tissue fibrosis and poor blood supply of the extremity.
