Abstract
Background:
Developmental dysplasia of hip (DDH) is the most common congenital musculoskeletal disorder in infants. Undiagnosed DDH result in shortening of the affected limb which affect the child's gait, decreased strength and increased risk of degenerative joint diseases in hip and knee joints. Hip ultrasonography provide an early diagnostic tool for DDH. Ultrasonography can provide detailed imaging of the hip before femoral head ossification
Aim of the work
This study aims to highlight the role of ultrasound as a screening tool for infantile developmental dysplasia of hip joint. Patient and methods:
50 pediatric patients referred to Mansoura University Hospital and Mansoura University Children Hospital in the period from November 2016 till May 2018. They were 33 females and 17 male patients with their ages below 6 months. The minimum age was 2 weeks and the maximum age was 18 weeks and 3 days with mean of 11.21 ±4.81 weeks. All patients underwent ultrasonographic examination with measurement of Graf alpha and beta angles.
Results:
The present study showed that the most prevalent referral cause is the cesarean section (44%) followed by oligohydraminos (22%) and positive family history (16%). The most detected hip type was Graf type I (52% in right hip and 50% in left hip) and the percentage of Graf type II was 44%in right side and 46% in left side while Graf type III was 4% in both sides.
Conclusion: ultrasonography is a good tool for assessment the DDH mostly in high risk cases.
Key words: developmental dysplasia of hip (DDH), ultrasound, oligohydraminos.
