    Abstract:
    Of the many methods of limb elongation, lengthening by physeal distraction is among the newest. The goal of this study was to estimate the long-term results of femoral and tibial lengthening by epiphyseal distraction. The authors examined 40 patients who underwent 24 femoral and 16 tibial lengthenings. The average follow-up period was 9.6 years. An average of 4.6 cm of femoral lengthening and 4.7 cm of tibial lengthening was achieved. The femoral healing index was 38.1 days/cm and the tibial healing index was 35.7 days/cm. After lengthening the epiphyseal cartilage started to function in all patients, and premature growth cartilage fusion was not observed during follow-up. Complications occurred in eight patients during femoral lengthening and in four during tibial lengthening. The authors suggest that physeal distraction is a good method for moderate and simple limb lengthening. Particular care should be applied to knee joint function, especially during femoral lengthening.
