Spine distraction implant

A spine distraction implant alleviates pain associated with spinal stenosis and facet arthropathy by expanding the volume in the spine canal and/or neural foramen. The implant provides a spinal extension stop while allowing freedom of spinal flexion. An interspinous process implant with a selectably expandable spacer can be placed between adjacent spinous processes. a device implanted between the spinous processes of adjacent vertebrae of the spine can be used for relieving pain associated with the vertebrae and surrounding tissues and structures by maintaining and/or adding distraction between adjacent vertebrae. A tissue expander can be adapted to move from a first insertion position, for ease of implantation between spinous processes, to a second retention position that prevents displacement of the implant. An embodiment of a system can include an implant having a spacer with a thickness and a wing, wherein a first configuration of the wing has a first height substantially similar to the thickness and wherein the wing is adapted to be selectably arranged in a second configuration such that the wing has a second height greater than the first height. A periphery of the implant has a shape generally conformal with a shape of an inner surface of a cannula and a cross-sectional diameter smaller than an inner diameter of the cannula. The cannula is inserted such that a proximal end of the cannula is arranged between the adjacent spinous processes. The implant is then urged into position between the adjacent spinous processes by way of the cannula, and subsequently arranged in a second configuration to fix the implant in position.

Offset helix surgical fixation screws and methods of use

A surgical fixation screw that can be driven with significantly reduced torque thus allowing for theaded fixation bodies to be made substantially of bioabsorbable materials. The novel fixation body, also called an offset helix fixation body, extends along a first (central) axis. The fixation body comprises first and second helically-mating members that mate along a constant-lead helical interface that extends about a second (non-central) axis. The second axis is angularly offset from the first axis of the fixation body from about 1° to 20°. Alternatively, the second axis is parallel to, but laterally offset from, the first axis. Thus, the first and second members of the fixation body can travel helically relative to one another about the helical mating interface between a first insertion configuration and a second anchor configuration. In the insertion configuration, the screw's outer periphery has a first (lesser) transverse sectional dimension to allow reduced torque in helically driving the screw into a space in a bone. After being driven into a space or bore, the first and second members then can be moved helically relative to one another about the helical mating interface to an anchor configuration in which the screws outer periphery is expanded radially outward to provide a second (greater) transverse sectional dimension for securing the fixation body in the space or bore.
