Thoracic/lumbar and cervical spinous process staples which staple/fuse adjacent spinous processes are disclosed. Thoracic/lumbar transverse process staples which staple/fuse adjacent transverse processes are also disclosed. Each embodiment has upper and lower claws connected by a ratchet spring mechanism, along with a multiplicity of bone fastener prongs attached to the upper and lower claws. Two sets of prongs on each staple claw are spaced by a distance approximately equal to the distance separating adjacent spinous or transverse processes so as to facilitate stapling/fusion of two adjacent processes. Also disclosed are staple prongs with multiple perforations which enable incorporation of bone fusion material thereby facilitating stapling/fusion of spinal elements.

The present disclosure relates to an interspinous omnidirectional dynamic stabilization device, including a first fixing part, a second fixing part, a connecting structure and an elastic structure, wherein the first fixing part and the second fixing part are fixedly connected to each other through the connecting structure and elastic structure, the bottoms of the first fixing part and the second fixing part are provided with one or more barbs, the elastic structure is made up of one or more U-shaped structures connected to each other, and the first fixing part and the second fixing part are provided with fixing holes respectively. The device is able to provide the maximum matching for the mobility in all directions, according to the requirements on the physiological activities of the human body, without causing stabilizing structures to be relatively displaced, or loosen and fall off. In addition, the device has a reasonably designed structure, with a small size. The device can be firmly fixed, and have a strong ability of elasticity attenuation resistance. In the device, the prosthesis has strong vertical support force at the bottom of the spinous process after implantation. Moreover, the device is fixed to the spinous processes and lamina, with the elastic structure attached to the spinous processes on either side of an interspinous space, and the bottom of the prosthesis is not forced to be close to the spinal dura mater, to reduce the risk of damaging the spinal dura mate during or after surgery.

A spinous laminar clamp system is disclosed herein. The preferred embodiments are either a three or a four-point fixation system at a particular vertebral level. For example, a two-point adjustable fixation below a vertebrae and a single-point non-adjustable point above the vertebrae exemplifies the three-point fixation. Multiple level and further stabilizing is provided by fixation to subjacent vertebrae above and/or below with a connecting rod providing unitization between levels. Specific designs are applicable to the cervical spine; however, fixation at all levels and regions of the human spine are contemplated.

Systems, devices, and methods for treating the spine are disclosed herein. Medical devices can be positioned along a subject's spine to treat various conditions and diseases. The medical device can include an actuator assembly and a clamp assembly. The actuator assembly can be positioned at an interspinous space between a superior spinous process and an inferior spinous process. The actuator assembly can be used to reconfigure the clamp assembly such that the clamp assembly clamps onto the superior and inferior spinous processes.

Embodiments herein are generally directed to derotation systems, apparatuses, and components thereof that can be used in spinal derotation procedures, as well as methods of installation. The derotation systems may include a plurality of derotation towers and clamp members.

A non-intrusive bone anchor for attachment to vertebral laminar processes with a main body which has a lower fixed jaw; a connecting portion to said lower fixed jaw, a bore hole providing basis for an axis from one side of said connecting portion to the other, and a threaded two ring clamp where each ring has an inner threaded surface with a threaded axis; An externally threaded shaft with a first and second end, where said first end has an internal torquing indent and a portion adjacent thereto for a locking mechanism to engage the outer portion of the clamping ring and said first end has a fixation protuberance. An upper jaw that cooperates with said externally threaded shaft and engages bone between said upper jaw and said lower fizzed jaw forming a diagonal across a clamped bone body; and an inter-anchor connector comprising an axis with a first connector end and a second connector end where said first connector end has a rod portion and said second end has a tulip rod fixer portion.

A bone attachment assembly may include an attachment head, a set screw configured to attach to the attachment head, and a rod surface with a first raised portion and a second raised portion that define a lowered portion positioned between the first raised portion and the second raised portion. The first raised portion, the second raised portion, and the set screw may be configured to directly contact a rod in order to retain the rod within the attachment head.

A bone anchor is provided for connecting a rod to a bone structure, the bone anchor having a rod housing configured to accommodate the rod; a cavity distal to the rod housing dimensioned to accommodate the bone structure; and a deployable purchase element capable of assuming a deployed position in which the purchase element protrudes into the cavity, and capable of assuming a non-deployed position in which the purchase element does not substantially protrude into the cavity.

The present invention is an implant for bone. The current implant is particularly useful in spinal surgical procedures.

A device for spinal correction includes a stabilizer assembly including a hinge including a first rod-bearing leaf; a second rod-bearing leaf rotatably coupled to the first rod-bearing leaf to provide coronal or sagittal freedom of movement, or both, of the stabilizer assembly; a locking mechanism to lock the first and second rod-bearing leaves at a desired angle; a first stabilizing rod coupled to the first rod-bearing leaf; a second stabilizing rod coupled to the second rod-bearing leaf; and a plurality of monoaxial or polyaxial links, wherein each monoaxial or polyaxial link is movably coupled to the first or second stabilizing rod and is movably couplable to a first spinal rod or a second spinal rod fixed to the spine; wherein the stabilizer assembly is couplable to the first or second spinal rod to stabilize the spine to prevent compression, distraction, or translation of the spinal cord during a spinal correction.
