Instrumentation and method for treatment of a spinal structure, comprising a n elongate member (22) including a deformable distal portion (22a) having an initial configuration for placement within the spinal structure and a deform ed configuration wherein the distal portion (22a) is outwardly deformed to form a cavity (C) in the spinal structure. The elongate member (22, 122) comprises a cannula member (32) and an actuator member (30) that is removably positioned within the cannula member (32) and configured to transition the deformable distal portion (22a) from the initial configuration toward the deformed configuration. The actuator member (30) is selectively removed from the cannula member (32) to provide a passageway (60) for delivery of a material (M) into the cavity (C) formed in the spinal structure. |
