Metaphyseal distraction for lower limb lengthening and correction of axial deformities.

Metaphyseal distraction with the Orthofix apparatus was performed on 10 patients (five femora and five tibiae). A retrospective review is presented. The follow-up time was 10-38 months. A satisfactory correction of leg length and axial deformity was achieved in all cases. There was no need for plating or bone grafting. All patients showed solid bony fusion at follow-up. Pin tract infections in seven patients resolved under antibiotic treatment. Problems of pin loosening and mechanical weakness of the distraction device are discussed.
