Ahii V. Complex X-ray diagnostic ultrasound of ankle joint damage in children.

On the basis of the conducted study, it was found that fractures of bones that form an ankle are more common in children of the age between 11-14 years (39.7%), namely, the injury peak occurs at 13 years (40.0%) both in boys and girls; with the distal epimetaphys of hucklebone being the main localisation (78.1%), fractures involving growth areas account for up to 72.7%, of which inner articular - 47.8%. Among the injuries of growth zones, the most often occurence, type III fractures, according to a Salter-Harris classification, - 38,7%, type II fractures - occurring in 33.9% of cases. The mathematical model of the medial and lateral ankle joints revealed that the most likely location of lesions occur in places of joint attachment to tibia and in the central part of calcaneal block, as a result of maximum rates of equivalent stress in these areas. The most frequent injury of the anterior ankle ligament (65.4%) also caused high rates of overpressure at the level of its attachment to a fibula (9,2082e6), that at 1, 59 times dominate the data on the tibia level (5,8102e6; p <0,01), which was confirmed by ultrasound. The proposed protocol of a complex X-ray ultrasound allowed to increase the accuracy of combined traumatic ankle injuries by 25.0% compared to the X-ray method and by 13.4% compared to the ultrasound method.
