  • Title: Circular external fixation in tibial nonunions.
    Author: García-Cimbrelo E, Martí-González JC.
    Journal: Clin Orthop Relat Res; 2004 Feb; (419):65-70. PubMed ID: 15021133.
    Abstract:
    The Ilizarov method based on compression-distraction and subperiostic corticotomy was used in 82 lower extremities. There were 45 tibial nonunions without a significant bone defect and 37 tibial nonunions with a bone defect that required radical removal of the necrotic bone and bone lengthening or bone transport. Bone healing was obtained in 39 of the 45 tibial nonunions without bone defect (mean bone healing, 5.4 months) and in all patients with bone defect (mean bone healing, 15 months for patients treated with bone transport) although secondary surgeries (autografting and tibial nails) were frequent (23 patients). Infection was eradicated in all patients after necrotic bone removal and bone transport. The final mean limb length discrepancy was 0.7 cm for the patients without a bone defect and 2.03 cm for the patients with a bone defect. In the patients in the bone transport group, residual axial deviation and residual limb shortening were common. Circular external fixation is a useful method to solve complex tibial nonunions in patients in whom internal devices and autografting have failed. Patients must be cooperative, and must understand the length of time the frame needs to be worn, and that complications are a probability.
