ULTRASOUND EVALUATION OF DEVELOPMENTAL DYSPLASIA OF THE HIP

Abstract

Purpose: Ultrasound is a well-known, sensitive imaging modality of the infant hip that has gained wide acceptance in the past 20 years. In this study, we tried to focus on the important role of the ultrasound examination in the diagnosis of different infant hip abnormalities especially the developmental hip dysplasia. The role of ultrasound in monitoring diseased hips and neonatal hip screening is also explained.

Patients: This study included 181 patients (their age's range is I

day -9 years). 108 normal babies were examined as normal case control,

47 patients had symptoms suggestive of dysplasia and 26 patients had painful hips.

Results: - Examination of the control group revealed high percentage of immature hips that needed follow up. - Examination of the symptomatising patients revealed

28 patients with dysplastic changes. Not all clinically unstable babies were sonographically abnormal. Ultrasound was used successfully m monitoring 6 patients treated by Pavlick harness. - Examination of the babies with painful hip revealed high percentage of those having septic epiphysitis, all these patients share a common history of previous admission to the neonatal care units.
