Conclusions Wide-bore 3-T closed MRI revealed significant kinematic changes in the menisci and tibiofemoral joint spaces in asymptomatic volunteers. However, in complex views the use of specific angle designations helps to define exactly how the radiograph was obtained. Conventional radiography is a fundamental tool in the diagnosis, staging and surgical planning of Blount-disease. Rajesh Purushothaman, Associate Professor, Medical College, Kozhikode, India.

For more information, click on the link if you see this icon, Growth disturbance in the proximal, medial, epiphyseal plate, epiphysis, and metaphysis of the tibia produces medial angulation (varus deformity) at the knee and internal rotation of the tibia, Infantile form is more common in females, African-Americans and the overweight, Adolescent form also is more common in overweight obese, Infantile form is usually free of pain whereas adolescent form is accompanied by pain, Infantile form is bilateral in 80% of cases and associated with greater deformity, Adolescent form is unilateral in 80% and associated with less deformity, The study of choice is a standing AP view of the knees and a lateral view, Infantile form is bilateral in 80% of cases and associated with associated with a prominent metaphyseal beak, Leg-length discrepancy (shorter on affected side), Fragmentation of the medial epiphysis which is wedge-shaped, Varus deformity is measure by the tibiofemoral angle, Severity of changes are assessed by using the metaphyseal-diaphyseal angle of the tibia, Angle is formed by lines between metaphyseal beaks and perpendicular to the longitudinal axis of the tibia; >11 degrees is abnormal, Common in toddlers who walk at an early age and are overweight; usually resolves spontaneously by age 2 years, Orthotic management includes long-leg, locked-knee braces, Indications for operative treatment include increasing severity of symptoms or progression of deformity, Adolescent Blount disease does not appear to be as progressive infantile form. 0000016873 00000 n Articular branches of femoral, obturator, common fibular, tibial, and saphenous nerves constitute the nerve supply to the tibiofemoral joint1. When a child is born, it has 10-15 degrees of physiological genu varum, 5 degree internal tibial torsion and external rotation contracture of the hip. . γ angle of 2°. The tibiofemoral angle created by these two axes was 5.3°, which, in comparison to eight other axis combinations tested on the short radiographs, correlated best (r = 0.94) with the mean tibiofemoral angle observed on the long radiographs.
