A child with a history of pain over lower extremities since few moths shows radiological evidence of osteosarcoma. Most common site of osteosarcoma is:
Upper end of femur
Lower end of femur
Lower end of fibula
Lower end of tibia
The classic form of osteosarcoma is typically seen in patients in their second or third decade, with a peak in the adolescent growth spu. It occurs more frequently in males than in females and is found in the metaphyseal areas of long bones, with 50% of lesions seen about the knee joint. The distal femur is the most common site, followed by the proximal tibia and then the proximal humerus. Ref: Randall R.L., Hoang B.H. (2006). Chapter 6. Musculoskeletal Oncology. In H.B.
