Abstract
The invention provides instruments and methods for prophylactic treatment of an osteoporotic vertebral body or for treating a vertebral compression fracture (VCF). In one exemplary method, a probe system uses a high speed rotational cutter for abrading or cutting a plane within vertebral cancellous bone. Optional irrigation and aspiration sources are included in the probe system for removing abraded bone debris. In one embodiment, the high speed cutter uses a tissue-selective abrading surface that abrades or cuts bone but does not cut soft tissue. After the creation of a weakened cut plane in the bone, reduction of the fracture requires reduced forces.
