Abstract


Purpose. To determine the features of reparative osteogenesis in 6-9-year-old patients with achondroplasia during tibial distraction.
Materials and Methods. Complex dynamic ultrasound examination (Voluson - 730 PRO, Austria) performed in 25 patients at the age of 6-9 years with achondroplasia after 10, 20, 30, 60 days of distraction. Qualitative and quantitative criteria presented which reflects a rapid course of osteogenesis in children. Vascularization features in the zone of lengthening demonstrated in CDS and ED modes.
Results. Reparative osteogenesis of high level established to be characteristic of children at the age of 6-9 years with achondroplasia requiring to perform dynamic USE and timely adjustments of distraction rate.
Conclusion. USE technique in patients at the age of 6-9 years with achondroplasia allows timely identification of qualitative and quantitative echo-signs of rapid osteogenesis throughout the period of distraction and adjusting treatment tactics thereby promoting favorable osteogenesis process and achievement of required lengthening amount.
