The Incidence, Diagnosis, and Treatment practices of Developmental Dysplasia of Hip (DDH) in India: A Scoping Systematic Review
2021
To identify literature on variations and knowledge gaps in the incidence, diagnosis, and management of developmental dysplasia of hip (DDH) in India. Following standard methodology and PRISMA-ScR guidelines, a scoping systematic review of literature on incidence, diagnosis, and treatment of DDH in India was conducted. Studies conducted in India, published in indexed or non-indexed journals between 1975 and March 2021, were included in the search. Of 57 articles which met the inclusion criteria, only 33 studies (57.8%) were PubMed-indexed. Twenty-eight studies (49%) were published in Orthopaedic journals and majority had orthopaedic surgeon as the lead author (59.6%). Sixteen studies were mainly epidemiological, 20 reported screening/diagnosis, and 21 reported treatment of DDH. Almost 90% of the studies (51) were Level 4 or 5 according to the levels of evidence in research. There is lack of clarity in the definition of hip dysplasia and screening/diagnostic guidelines to be used. The incidence of hip dysplasia in India is reported to be 0–75 per 1000 live births, with true DDH between 0 and 2.6/1000. Late-presenting DDH is common in India, with most studies reporting a mean age of > 20 months for children presenting for treatment. The treatment is also varied and there is no clear evidence-based approach to various treatment options, with lack of long-term studies. This systematic scoping review highlights various knowledge gaps pertaining to DDH diagnosis and management in India. High-quality, multicentric research in identified gap areas, with long-term follow-up, is desired in future.
