Abstract

Marfan's syndrome is an autosomal dominant disorder of connective tissue, commonly involving the cardiovascular, ocular, and skeletal systems. Revised criteria for the clinical diagnosis of Marfan's syndrome regard skeletal involvement as a major criterion if at least four of eight typical skeletal manifestations are present, one of which is protrusio acetabuli, Using Kulman's method to determine the presence of protrusio, we analysed the pelvic X-rays of 15 patients with Marfan's syndrome and 15 controls, Protrusio was present in 47% (7/15) of Marfan patients, compared with 7% (1/15) of controls (P = 0.035). Using the revised criteria, the presence of protrusio would have affected the final diagnosis of Marfan's syndrome in only one patient out of 15, Therefore, we recommend that a pelvic X-ray is reserved for those cases in which the presence of protrusio will alter the final diagnosis, With regard to the radiological assessment of protrusio, in our opinion this can be performed simply and reliably using the position of the acetabular line alone.
