Objective. The aim was to determine efficacy and safety of a surgical method to reduce adult height in extremely tall adolescents. Methods. Data for all girls (n = 12) and boys (n = 9) in our center subjected to bilateral percutaneous epiphysiodesis around the knee who had reached final height were included. Final height predictions were based on hand and wrist X-rays before surgery. Results. When compared to prediction, adult height was reduced by 4.1 ± 0.7 cm in treated girls (P < .001) and 6.4 ± 0.7 cm in treated boys (P < .001) corresponding to a 33.6 ± 3.4% and 33.6 ± 4.2% reduction of remaining growth, respectively. Besides mild to moderate postoperative pain reported in 9 operated individuals, no other side effects were reported. Postoperative X-rays confirmed growth plate closure and absence of leg angulations. Conclusions. Bilateral epiphysiodesis is an effective and safe method to reduce adult height in extremely tall girls and boys.
