A 12 year old boy presents with chronic knee pain for 2 years/. Knee x ray is shown. Probable diagnosis:
* The x-ray shows lower end of femur with flaring and irregular margins but the epiphysis is normal.* There is no white line in epiphysis, hence scurvy is ruled out.* Absence of lytic lesions rules out hyperparathyroidism.* Malignancy is ruled out as there is no periosteal reaction or bone growth is seen.* Rickets shows flaring of metaphysis and widening of the growth
Chronic osteomyelitis
Osteosarcoma
