Abstract

Despite MR potentials, few studies investigate the features of normal hips and of hip osteochondrosis in early and late childhood. We report our personal experience with MRI of hip osteochondrosis in pediatric patients. MR images were obtained with total body MR equipment at medium and high fields. The normal hips were studied in children aged 34 months to 6 years with abdominal-urinary tract disorders and in 9 patients of the same age with unilateral Perthes disease. Hip osteochondrosis was studied in 6 children with Catteral's type III and IV and in 3 with type I and II disease. General anesthesia was never necessary to perform MRI. MRI exactly defined the cephalic anatomic profiles of normal hips which are not depicted with conventional radiography before the femoral head cartilage ossifies completely. MR contrast resolution was very high in depicting the maturation of the epiphyseal nucleus and its exact site in the cartilagineous epiphyseal hemisphere proximal to the femur. The analysis of MR morphological and structural changes permitted to correlate MR findings with the histopathologic features described in the literature. In addition, MRI of childhood hip osteochondrosis showed maked structural changes of the epiphyseal...Continue Reading

Biomechanics

Biomechanics examines the generation of internal forces within the body and investigates the effects and control of forces that act on or are produced on tissues. Here are the latest discoveries.
