Study of Developmental Hip Dysplasia in Saudi Infants Using Ultrasonography

ABSTRACT

The objectives of this study were to characterize the DDH in Saudi infants using US, also to evaluate the hip joint for infants who were clinically diagnosed to have Developmental hip dysplasia (DDH) focusing mostly on the Graf’s method using ultrasonography, by measuring the α and β angles and correlate the results with the anatomical findings related the hip. The study was conducted during the period extended from 2011 up to 2017. The hips of 536 newborn infants were examined by US using routines screening program for DDH at age 1 day up to 4 months. Ultrasonographic examination was performed with a 12-7.5,3.5, 5 MHZ, linear transducer (Toshiba, Philips 2010, volusum4000, Son layer SSA-270A, Japan). The sample including 145 (27.1%) females and 391(72.9%) males. Participant's age were < 3m, 75 were 2b >3m and 29 were 2c. 44 were type 3 and 30 were type 4 with significant relation with age
