Diagnosing Developmental Dysplasia of Hip in Newborns Using Clinical Screen and Ultrasound of Hips-An Indian Experience.

Abstract

To study the cost-effectiveness of clinical screen with ultrasonography (USG) of hip for diagnosing developmental dysplasia of the hip (DDH) in newborns. Retrospective study (2006-14). Term newborns had (i) target scan at 6 weeks-family history of DDH or breech presentation-and (ii) early scan-abnormal clinical screen. In all, 736 babies had USG scan. Five early scans (Graf's classification; three Type IIA, one Type IIC and one Type IIIB] and 15 target scans (Type IIA) were reported abnormal. All Type IIA DDH had subsequent 12 weeks' scans normal. Babies with Type IIIB and IIC had hip reduction surgery at 6 and 16 months of age, respectively. At cost 200 INR/scan, total 147 200 INR was incurred against two possible hip replacements prevented. Universal clinical screen with USG of hip can aid in early diagnosis of DDH in newborns. Large population-based studies from developing countries need to look in its cost-effectiveness.
