Objectives: Developmental dysplasia of the hip (DDH) describes a wide spectrum of abnormal hip development and maturation defects. Till date, there have been many classifications proposed to describe the severity of the disease based on individual hip joint pathology and radiological appearance. None of these classifications has taken patients with the bilateral hip disease into consideration. A new radiological classification system based on plain pelvic radiographs has been presented, combining all the pathological possibilities in both unilateral and bilateral cases and its reliability was assessed in patients aged 6-months and older. Methods: The plain anteroposterior pelvic radiographs of 120 DDH patients were classified according to the suggested classification system by five orthopedic surgeons. Inter- and intra-observer reliability was assessed to determine the reliability and validity of the new classification system. Results: Intraobserver differences were on an average 0, and interobserver differences were negligible. The intra- and inter-observer reliability was >97%. Conclusions: The classification system developed and tested in this study is highly reliable. Our system represents a complete classification than the systems already existing. This system of classification if applied in clinical practice will help in better describing and comparing the outcome in patients with bilateral disease instead of just focusing on the outcome of individual hip joints.
