Orthopedic manifestations of acute pediatric leukemia

The variety and distribution of skeletal lesions in children with acute lymphoblastic leukemia is rarely seen in other diseases. Skeletal radiographic changes that can occur in a child with acute leukemia include diffuse osteopenia, metaphyseal bands, periosteal new bone formation, geographic osteolysis, osteosclerosis, mixed osteolysis and sclerosis, and permeative destruction. It is important for orthopedic surgeons to recognize the skeletal manifestations of acute leukemia of childhood because the physician who initially evaluates the child will often be an orthopedic surgeon, and a delay in diagnosis has an adverse affect on survival.
