Final answer:
The fracture is classified as a pathological fracture and requires closed reduction as the treatment.
Step-by-step explanation:
The fracture in the tibia caused by bone cancer is classified as a pathological fracture. This type of fracture occurs when a bone weakens due to an underlying disease or condition. In this case, the weakened tibia broke due to the presence of bone cancer.
The treatment needed for this fracture would be closed reduction. Closed reduction refers to the realignment of the fractured bone without the need for surgery. It involves manipulating the broken bone back into its proper position and then immobilizing it with a cast or splint.
So, the classification of the fracture would be pathological fracture and the treatment needed would be closed reduction.
