There is some proximal limb hypotrophy, and mild bowing deformity of the distal portions of the upper and lower extremities. In the posterior left iliac crest there is one palpable lesion which is just a few centimeters in size. On the left wrist there is about 15 to 20% loss in both supination and pronation, and over radial side of the wrist on the distal radius there is a palpable lesion. There is significant valgus deformity of both ankles. Radiographs of upper and lower extremities, wrists and feet, ankles, and pelvis are made. Assessment of the balance of the skeleton, including the humerus, femur, tibia, fibula, hands and feet show a various lesions that are in general relatively small or have been surgically treated, and there are no signs of aggressive destructive or malignant behavior in any of the visualized lesions. Standing radiographs of the ankles show that there is significant valgus deformity of both ankles, with the left side worse than the right. There is at least a 20 degree valgus deformity of the left tibial plafond. What treatment should be recommended?
