Shifting a page image while it is still in compressed form. The hosel insert is secured to the hosel portion and includes at least one inwardly extending pawl. The valve assembly is a one-way valve assembly that relieves pressure within an annulus formed between adjacent casings andor tubular members to prevent burst or collapse of the casings andor tubular members. The actuator driving circuit applies a drive signal to the actuator to cause the relative motion, and has a small signal bandwidth of at least 200 kHz with a phase lag of not more than 100 degrees within the small signal bandwidth. The robotic mechanism may be utilized to position the cannula through which the flow of synthetic bone material or cement is conducted into the space created in the vertebra by expansion of the balloon or bladder. Other embodiments may be described and claimed.
