Abstract:
1. A method of treating an abnormal vertebra, comprising: providing a flow source having at least one outlet port and configured to provide a bone fill material inflow into cancellous bone of a vertebral body; inflowing bone fill material into an interior of the vertebral body while controlling the viscosity of the flow of bone fill material through the controlled application of energy, the introduction of the fill material being controlled causing flowing of the flowable bone fill material along a flow path into the cancellous bone of the vertebral body without previously creating a cavity that compresses or compacts cancellous bone, wherein between an outer region of the flow path and the at least one outlet port in the flow path, the flow path comprises flowable infill material interdigitating with cancellous bone; measuring a characteristic of the bone fill material; and adjusting an inflow parameter of the bone fill material inflow in response to the measured characteristic of the bone fill material so that the bone fill material controllably permeates and interdigitates with the cancellous bone in the flow path.
