Complications of leg lengthening: 46 procedures in 28 patients

The results and complications of 46 leg-lengthening procedures in 28 consecutive patients were analyzed retrospectively. There were 24 femoral and 22 tibial lengthenings, performed for short stature (5 patients) and limb-length discrepancy (23 patients). Three methods were used: diaphyseal osteotomy, metaphyseal corticotomy, and distraction physiolysis. In the second group a satisfactory result was obtained more often and a lower complication rate was observed. The overall complication rate was high: 45 substantial problems occurred. We conclude that leg lengthening is difficult, requiring good preoperative examination and planning, and should be carried out only in specialized centers.
