Characterization of Developmental Hip Dysplasia in Saudi infants using Ultrasonography
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 7
Abstract
Developmental dysplasia of the hip (DDH) represents a spectrum of anatomic abnormalities that can result in permanent disability. Ultrasonography(US) technique allows evaluation of different anatomical structures and their pathological changes, in the bony profile of the joint surfaces, ischial tuberosity, and greater trochanter .The objective of this study is to characterize the DDH in Saudi infants using US .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 0days up to 4 months. The sample including 145(27.1%) females and 391(72.9%) males. All infants were examined clinically and underwent US of the hip.US was performed with a 7.5-3.5 ,5 MHZ, but most examination were performed with 3MHZ linear transducer (Toshiba, Philips 2010, volusum4000, Son layer SSA-270A, Japan)using Graf method. The most common affected age were ages<30 days, 280 were of type1, 9 were 2a < 3m, 75 were 2b >3m and 29 were 2c. 44 were type 3 and 30 were type 4 with significant relation with age at p=0.018, 0.000, 0.005 for type 1, 2, and 4 respectively .There is significant relation between type 2 and 3 dislocation and the risk factor. When characterizing hip joint and its development in different types of DDH, results showed that the acetabulum is well developed in type 1 and least developed in type 3 and 4 significantly the femoral head is outside the acetabuler cavity in both type 3 and 4 while it was found inside the groove in type 1 .The ischium is found to be well developed in type1 while in type 3and4 most of the cases were not developed .Normal Illiac line capsule, acetabular cartilage, Femoral head ligament were detected in type 1 where significant changes were detected in type 3 and 4 . Regarding the results; US has documented its ability to detect abnormal position, instability, and dysplasia not evident on clinical examination as well screening of all infants at risk . Consequently, the use of US is recommended as an adjunct to the clinical evaluation. It is the technique of choice for clarifying a physical finding, assessing a high-risk infant, and monitoring DDH, it can guide treatment and may prevent overtreatment
