Bilateral and Symmetrical Anteromedial Bowing of the Lower Limbs in a Patient with Neurofibromatosis Type-I

Figure 2

AP standing radiograph at the age of 7 years showed squaring of the iliac wings, coxa vara, and bilateral and symmetrical lateral bowing of the femora associated with thickening of the cortices. The tibiae and fibulae showed bilateral sabre deformity with posteromedial bowing between the middle and distal thirds of the tibia. Thickening of the tibial cortices was evident. The fibulae showed broadening/“tibialization” and posterior cortical thickening of the two bones.
