Abstract

Background: Dysplastic hips infants may normalize spontaneously without any intervention due to the natural growth. However, some infants need one or more surgical interventions to achieve stable and non-dysplastic hips. The purpose of this study is to determine the proportion of infants diagnosed with DDH before the age of 6 months undergoing surgical procedures of the hip(s) before the age of four years and to determine the number and types of surgical procedures in each infant.

Methods: A prospective and consecutive study of all infants aged 0-6 months diagnosed with dysplasia of the hips in the combined paediatric orthopaedic and radiologic examination in the Region of Southern Denmark 2013-2017. From medical records, we obtained information about all surgical procedures in the hips including open or closed reductions, arthrographies, tenotomies, and pelvic osteotomies before the age of 4 years.

Results: Overall, 281 infants with hip dysplasia were included. The median age at first examination was 48 days. In 254 (90%) of the infants, the hips resolved spontaneously, and 27 (10%) needed one or more surgical interventions. Overall, the 27 infants had 47 surgical intervention as 12 infants had more than one intervention. One infants had five surgical interventions. The most frequent surgical procedures were closed reduction and arthrography with or without adductor tenotomy (58%) and pelvic osteotomy (27%). Among infants with surgical interventions, 23 (8.2%) had unstable hips, and four (1.4%) had stable hips. All four infants with stable hips had an arthrography and none required a pelvic osteotomy.

Discussion: This study supports the propensity for spontaneous normalization early dysplasia of the hips in infants. Only a small proportion of the infants needed surgical interventions to achieve stable and non-dysplastic hips.
