A bone cage may include first and second spaced apart frames defining a bone ingrowth cavity therebetween, a plurality of first protrusions each having a proximal end coupled to the first frame and a distal end extending into the cavity toward the second frame but not contacting the second frame, and a plurality of second protrusions each having a proximal end coupled to the second frame and a distal end extending into the cavity toward the first frame but not contacting the first frame. Furthermore, the distal ends of the first protrusions may be laterally offset from the distal ends of the second protrusions.

An implant device having a non-conductive base structure with at least two exposed or exterior surfaces wherein at least one of the exposed or exterior surfaces has attained electrical conductivity on at least portions of the surface by an energy exposure wherein portions of the exposed or exterior surfaces are transformed by the energy exposure to attain the electrical conductivity.

Bone growth enhancing implant

The invention is directed to an interbody fusion device comprises a load bearing component and a retention component and further comprises two bone screws that pass through the retention device and into the vertebral bodies. When implanted, the construct is flush with the anterior face of the vertebras and provides support and temporary fixation for the ultimate fusion of the vertebral bodies.

Collapsible two-piece olif implant

A method and apparatus is provided for use in spinal fusion procedures. An interbody fusion device has a first piece that is a load bearing device designed to bear the axial loading from the end plates of adjacent vertebrae. A second piece of the interbody fusion device is a retention device whose function is to prevent migration of the load bearing device. One or more fasteners secure the retention device to the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion. The second piece can be configured to include lips that abut the apothyseal rings during, with the plate including bores angled such that fasteners penetrate the apothyseal rings.

Interbody fusion device with lipped anterior plate and associated methods

A method and apparatus is provided for use in spinal fusion procedures. An interbody fusion device has a first piece that is a load bearing device designed to bear the axial loading from the end plates of adjacent vertebrae. A second piece of the interbody fusion device is a retention component whose primary functions are to prevent migration of the load bearing device and loss or migration of graft material from within the load bearing device. A secondary function of the retention component is to address fixation of fasteners when the surgeon is confronted with a challenging access to adequate boney structures due to excessive curvature/angulation of the vertebrae column, minimal invasive surgery techniques, danger to surrounding vascular or neurological tissues, poor bone quality, or similar surgical complications. A tertiary function of the retention component is to provide better alignment and stabilization of misaligned vertebrae when spondylolisthesis is a significant factor. One or more fasteners secure the retention component to each of the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion.

Interbody fusion device and associated methods

A spinal rod implantation system may be used with pedicle screws to be secured to respective pedicles of a patient's spine, each pedicle screw having a spinal rod channel therethrough. The system may include extenders each including an inner member having a distal end, and an outer member surrounding the inner member and being slidable relative thereto to permit removable coupling of the distal end to a respective pedicle screw. The inner and outer members may include respective features defining a first joint permitting at least partial relative rotation to provide a first degree of rotational freedom. The system may further include extender heads each pivotally coupled to a proximal end of a respective outer member to define a second joint providing a second degree of rotational freedom. A spinal rod insertion assembly may be coupled to the extender heads for guiding the spinal rod through the spinal rod channels.

A surgical draping method for a patient on an operating table and an adjacent movable medical tool may include positioning a patient drape having a surgical access opening in a medial portion thereof over the patient on the operating table so that the surgical access opening exposes a surgical site on the patient. Opposing medial side portions of the patient drape may be fastened together underneath the operating table to provide a pathway thereunder for passage of at least one portion of the medical tool therethrough. An equipment drape may be positioned adjacent a side of the operating table aligned with the pathway to cover the at least one portion of the medical tool when moved through the pathway.

An intervertebral support device may include a body having opposing first and second end faces, opposing top and bottom faces extending between the first and second end faces, and opposing side faces extending between the first and second end faces. A first diagonal direction may be defined between a first vertical corner at the first end face and a diagonally opposite second vertical corner at the second end face, and a second diagonal direction defined between a second vertical corner at the first end face and a diagonally opposite first vertical corner at the second end face. The body may have a tapering height decreasing from the first end face to the second end face, and while also tapering more quickly in the first diagonal direction than the second diagonal direction to provide a corrected angle of spinal curvature upon positioning between adjacent vertebral bodies in a human spine.
