The present invention relates to an implantable anterior cervical plate having a stackable superior design, which deflects soft tissue.

An implantable modular plate system for stabilizing adjacent vertebral bodies in a cervical spine includes at least two plate segments aligned or connected together so as to form a connection at and along adjacent ends. At least one of the plate segments includes a flange at an engagement end and at least one of the plate segments including a flange recess at an engagement end, the flange being configured for overlay engagement with the flange recess when the at least two plate segments are engaged. The plate segments are pivotable out of plane with one another at a common axis of rotation traversing overlapping portions of the adjacent ends and are constrained from rotation by the flanges such that the rotation of each plate segment is limited to up to 90 degrees of rotation away from the contact surfaces of the flange and flange recess.

A method for treating a spine is provided. The method includes the steps of: disposing an interbody implant adjacent a first vertebral surface and a second vertebral surface of an intervertebral disc space, the interbody implant engaging the vertebral surfaces at a selected angular orientation; connecting the interbody implant with at least one of the vertebral surfaces via at least one fastener that is engaged with the interbody implant and fixed with the vertebral surface such that the at least one fastener is movable to a plurality of axial orientations relative to the interbody implant; and manipulating the vertebral surfaces such that the at least one fastener is fixed relative to the interbody implant. Spinal implants, surgical instruments and systems are disclosed.

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.

Patient-specific systems and methods are provided for assisting in medical procedures, and can include producing patient-specific devices from computer models of a patient's anatomy, including a first patient-specific device configured to identify and allow access to a resection area in an operation location for a medical procedure; a second patient-specific device configured to refine the procedure, following use of the first patient-specific device and in some embodiments, to identify and allow access to installation locations for an implant and/or surgical hardware; and/or a third patient specific device configured to assist in confirming placement of the implant and/or surgical hardware and refining the procedure, following use of the first and second patient-specific devices. Each of these devices may be developed from patient-specific computer model data via patient-specific image data and may enhance a variety of procedures.

An apparatus for securing a vertebra during healing of a fracture within a pars area of the vertebra is described. In certain embodiments, the apparatus is a plate that has an outer shape similar to a shape of a pedicle and/or lamina of the vertebra, and an inner section that facilitates access to the pars area when the plate is secured to the vertebra.

An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

A system for stabilizing a cervical spine segment utilizing uncinate joint stabilization, includes a stabilizing bridge for bridging across intervertebral disc space of the cervical spine segment to mechanically couple between a pair of uncinate joint stabilizers positioned in a respective pair of uncinate joints of the cervical spine segment. A method for stabilizing a cervical spine segment utilizing uncinate joint stabilization includes (a) positioning a pair of uncinate joint stabilizers in respective uncinate joints of the cervical spine segment to stabilize the uncinate joints and thereby stabilize the cervical spine segment (b) and implanting, in intervertebral disc space of the cervical spine segment, a stabilizing bridge that mechanically couples between the uncinate joint stabilizers across intervertebral disc space of the cervical spine segment.

An implant for insertion into a disc space between vertebrae, wherein the implant includes a spacer portion, a plate portion coupled to the spacer portion, two bone fixation elements for engaging the vertebrae and a retention mechanism for preventing the bone fixation elements from postoperatively backing-out of the plate portion. The retention mechanism may be in the form of a spring biased snapper element that is biased into communication with the bone fixation elements so that once the bone fixation element advances past the snapper element, the snapper element is biased back to its initial position in which the snapper element interfaces with the bone fixation elements. Alternatively, the retention mechanism may be in the form of a propeller rotatable between a first position in which the bone fixation elements are insertable to a second position where the bone fixation elements are prevented from backing-out.

Spinal device/implants are provided, comprising a spinal device/implant and a sensor.
