X-ray and MRI showing three case scenarios including specific answers for treatment options. None of the cases involved skip metastasis, metastatic disease, intra-articular tumour infiltration, or pathological fracture. (a) Male, 6.5 years at initial diagnosis, osteosarcoma of distal femur, and femur length (greater trochanter to eminentia intercondylaris) is 290 mm. (b) Female, 8.0 years at initial diagnosis, osteosarcoma of distal femur, and femur length (greater trochanter to eminentia intercondylaris) is 340 mm. (c) Male, 10.5 years at initial diagnosis, osteosarcoma of distal femur, and femur length (greater trochanter to eminentia intercondylaris) is 320 mm.
