The Importance of Modified Budin Incidence in the Radiological Diagnosis in Patients with Aseptic Necrosis of the Femoral Head

This study included 56 patients who presented hip pain occurring spontaneously without any trauma history. A new radiological protocol was initiated for all the patients suspected of NACE A pelvis, Dunlop profile and modified Budin at both hips scan was performed. In order to emphasize the effectiveness of the new radiological protocol, the following indicators were analyzed: the mobility of the affected hip, the radiological changes typical to the aseptic necrosis of the femoral head, the extension angle of the necrosis area on every incidence after Kerboul [1,2], the surface area covering the necrosis zone on every incidence and the coverage on every patient. The modified Budin profile has a greater diagnostic value for the early stages of NACF than the Dunlop profile and the radiography. The Budin incidence is important in order to differentiate stage III of NACF from stage IV by highlighting the degenerative changes in the acetabular cavity.
