Unilateral bone Transport System using Bifocal Monofixator / 대한정형외과학회잡지

ABSTRACT

Limb lengthening with any kind of lengthening apparatus is accepted as a standard method to correct leg length discrepancy. And furthermore, the deformity accompanying shortening is corrected by multifocal lengthener. twenty two patients have undergone lower limb reconstruction by the technique of unilateral bone transport for diaphyseal bone defect, nonunion or deformity in the presence of shortening from May 1990 to August 1993 in Wilson Leprosy Center & Rehabilitation Hospital. All Patients had bifocal procedure using bifocal monofixator(Orthofix) and bone defects were graduaily filled by bone transport. Average healing index(days/cm)was 61. Average bone defect was 7,4cm, and average transported length was 5.4cm. In conclusion, the unilateral bone transport system using bifocal monofixator has satisfactory outcome, and salvaged limbs where amputation has been previously the only option.
