Developmental Dislocation of Hip Misdiagnosed as Traumatic Posterior Hip Dislocation

Abstract

A 47-year-old woman was presented to the emergency department. The limb of the patient was shortened, and her hip was mildly flexed, adducted, and internally rotated. Initially, the patient was misdiagnosed as posterior hip dislocation. However, after careful history taking and radiologic evaluation, her final diagnosis was developmental dysplasia of hip, which was a sequelae of poliomyelitis.
