摘要： A system (10) for forming an implant (M) to stabilize an interior of a vertebral body (12) is provided. The system (10) includes a delivery cannula (18). A plurality of elements (20) are disposed adjacent to one another in the delivery cannula (18) with void spaces (63) defined between the elements (20). A fluent material (22), capable of setting to a hardened condition, is disposed within at least a portion of the void space (63) in the delivery cannula (18). A push rod (24) is movably disposed within the delivery cannula (18) to apply a force to move the elements (20) through the delivery cannula (18) and into the interior of the vertebral body (12). Upon application of the force, the elements (20) simultaneously carry the fluent material (22) through the delivery cannula (18) and into vertebral body (12) to delivery the fluent material (22) at a low pressure. The fluent material (22) sets to the hardened condition to secure the elements (20) and form the implant (M).
