A device and method for treating bone fractures/lesions using an inflatable body is provided. The inflatable body has a substantially flat horizontal surface for quick easy insertion into bone beneath the fracture so as to align misaligned fragments of the fracture and/or to collapsed bone. The substantially flat horizontal surface having a radio-opaque material has a higher durometer (less elastic), along the balloon web, than the rest of the inflatable body providing for optimum compression of the bone marrow.
