###Human: Is it advisable to put cast for green-stick fracture in a 6-month-old? ###Assistant: Hi. Your daughter has greenstick fracture of the distal femur. The cast which your doctor is asking to apply is hip spica. First of all, ideally hip spica should be applied under anesthesia to facilitate reduction of bone fragments but in this case, since no reduction is required, so no need to apply it under anesthesia. Secondly, since the fracture is around the knee, that is in the distal part of the femur bone, so a high above knee good cast will also do. No need to extend it to other leg and abdomen.
