Diagnostic Performance of Clinical Examination Versus Ultrasonography in the Detection of Developmental Dysplasia of Hip: A Systematic Review and Meta-Analysis.

Background: Developmental dysplasia of the hip (DDH) is a spectrum of diseases involving the femoroacetabular joint. Due to the controversies over the value of different strategies used for DDH screening, this systematic review and meta-analysis aimed to assess the diagnostic performance of standard physical examination maneuvers on the diagnosis of DDH, compared to the Graf ultrasonography (US) method.

Methods: PubMed, Web of Science, and SCOPUS databases were searched until the end of October 2020.
