Orthofix LRS monolateral fixators were used for femoral lengthening and either Ilizarov-type or hexapod-type circular external fixators for tibial lengthening. Tenotomies of the hip flexors and the Achilles tendon were performed to prevent injury to the growth plates and to prevent joint contractures. Results and complications were evaluated according to Paley\u2019s scoring and complication systems.\n\nResults: Average follow-up time was 35 (range: 26 to 76) months. The femora were lengthened by an average of 7.07 cm (46.1%), and the tibiae by an average of 6.64 cm (52.9%). Patients gained an average of 16.9 cm in height, including physiological growth. The mean bone-healing index (BHI) was 31.2 days\/cm for the femora (range: 17.4 to 43.3 days\/cm) and 34.3 days\/cm for the tibiae (range: 19.5 to 60.0 days\/cm). Complications included 3 delayed maturations, 3 pin track infections, 5 transient fibular paralyses, 5 regenerate fractures, 1 late varus deformity, 1 knee contracture and 1 knee contracture secondary to knee dislocation. Functional scores were excellent in 78 segments, good in 8, fair in 1 and poor in one. There was no growth inhibition related to the lengthening.\n\nConclusion: Bilateral simultaneous lengthening of the femora and tibiae in achondroplastic patients provided a reduction in total treatment and external fixation time, with a low rate of complications.\n\n \n\n\u00d6zet\n\n \n\nAma\u00e7: Bu \u00e7al\u0131\u015fmada akondroplastik hastalar\u0131n femur ve tibialar\u0131n\u0131n bilateral ve e\u015f zamanl\u0131 olarak uzat\u0131lmas\u0131n\u0131n do\u011furaca\u011f\u0131 sonu\u00e7lar ve komplikasyonlar analiz edildi.\n\n\u00c7al\u0131\u015fma plan\u0131: \u00c7al\u0131\u015fmaya 44 femur ve 44 tibias\u0131nda e\u015f zamanl\u0131 uzatma yap\u0131lan 22 akondroplastik hasta (16 k\u0131z, 6 erkek; ortalama ya\u015f: 6.36, da\u011f\u0131l\u0131m: 3-11) al\u0131nd\u0131.
