A spinal implant comprises an implant body extending between an anterior surface and a posterior surface, and including a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an inner surface that defines at least a first cavity and a second cavity. The cavities are oriented to implant fasteners in alignment with an oblique surgical pathway relative to a bilateral axis of a subject body and adjacent an anterior portion of an intervertebral space of the subject body. Systems and methods are disclosed.

An adjustable spinal stabilization system for maintaining preselected spacing and movement between adjacent vertebrae in a spinal column and for providing overall stability thereto. The system includes at least one interlaminar member positioned in the spaces intermediate a first vertebra and the vertebrae positioned immediately above or immediately below and adjacent to the first vertebra. The interlaminar member is operatively connected to an adjustable support structure and cooperates therewith to maintain the preselected spacing between adjacent vertebrae and to provide overall stability to the spinal column.

A surgical compression instrument includes a member configured for disposal longitudinally along a first implant support for pivotably connecting the first implant support with a second implant support. The first implant support is engageable with a first receiver of a first fastener having a first shaft fixed with vertebra tissue and the second implant support is engageable with a second receiver of a second fastener having a second shaft fixed with vertebral tissue. A part is movable relative to the member and engageable with the implant supports such that the second implant support moves relative to the first implant support to compress the vertebral tissue. Surgical systems, constructs, implants and methods are disclosed.

Spinal correction surgical techniques and methodologies for correction of scoliosis using non fusion anterior scoliosis correction, including soft tissue releases, unique correction techniques such as de-rotation, and unique single and dual anchor screw/cord applications.

The present disclosure includes a polyaxial bone fixation element for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The polyaxial bone fixation element preferably includes a bone anchor, a collet, a body, and a locking cap. The polyaxial bone fixation element preferably enables in-situ assembly. That is, the polyaxial bone fixation element is preferably configured so that in use, the bone anchor may be secured to the patient's vertebra prior to being received within the body. Accordingly, the polyaxial bone fixation element enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body can be snapped-onto the bone anchor. The bone anchor preferably also includes a second tool interface so that a surgical instrument can be directly coupled to the bone anchor.

The disclosure relates to devices and methods for implantation of an orthopedic device between skeletal segments using limited surgical dissection. The implanted devices are used to adjust and maintain the spatial relationship(s) of adjacent bones. Depending on the implant design, the motion between the skeletal segments may be increased, limited, modified, or completely immobilized.

A system for correcting a position of bones, bone parts, or vertebrae includes a first bone anchor including a shank for anchoring in bone and a receiver for connecting a rod to the shank, a second bone anchor including a shank for anchoring in bone and a receiver for connecting the rod to the shank, and an instrument including a positioning member, a first coupling member for coupling the positioning member to the first bone anchor, and a second coupling member for coupling the positioning member to the second bone anchor. The first and second coupling members are movable relative to one another. The receiver is pivotable relative to the shank for at least one bone anchor. The at least one bone anchor can assume a locked configuration where an angular position of the receiver relative to the shank is locked while the rod remains movable relative to the receiver.

Spinal correction surgical techniques and methodologies for correction of scoliosis using non fusion anterior scoliosis correction, including soft tissue releases, unique correction techniques such as de-rotation, and unique single and dual anchor screw/cord applications.

The present application is generally directed to improved instruments and instrument features for distraction and tissue retraction. In particular, the present application is directed to distraction blades and wide blocking blades that can be used together, or individually, to assist in the distraction of bone and the retraction of tissue during a surgical procedure, such as a spinal fusion procedure.

An instrument for spinal rotation that aligns and holds direct vertebral rotation (DVR) lever arms relative to each other to achieve an initial axial alignment of a segment of vertebrae and allows the final DVR rotation by rotating the instrument and lever arms together. A method of direct vertebral rotation that allows rotating the vertebrae to be aligned relative to each other, and collectively rotating the vertebrae to be aligned relative to adjacent spinal segments by rotating the direct vertebral rotation instrument. A system for direct vertebral rotation having at least two pedicle screws. The system also includes at least two levers attachable to the pedicle screws and a clamping instrument configured to clamp the levers.
