The bone medical implants include at least one rotational fixation mechanism that further includes or is attached to one or more sharp protrusions configured to penetrate and become lodged into hard tissue to provide support and positional stability. Such support is useful to ensure that the spinal bone graft may be used without additional stabilizing or anchoring structures, such as supporting plates or screws.

The retractor system includes a plurality of blade assemblies coupled to a handle assembly, wherein each of the blade assemblies may be independently adjusted (e.g. length blade and/or blade angulation and/or blade rotation relative to the handle assembly) to provide unprecedented customization of an operative corridor extending to the surgical target site of the patient such that any number of spinal surgery procedures may be undertaken by a surgeon, including but not limited to spinal fusion procedures at the L5-S1 disc space.

Abstract: An adjustment tool configured to adjust an intervertebral implant comprises a housing, a traveler member, a tether member, and a drive member. The traveler member is coupled to the housing. A proximal end of the tether member is coupled to the traveler, and a distal end of the tether member is configured to couple to the implant. The tether member is substantially linearly fixed to the traveler and rotatable relative to the traveler. The drive member is configured to transition between 1.) a first position in which the drive member is coupled to the tether such that rotation of the drive member causes rotation of the tether relative to the traveler, and 2.) a second position in which the drive member is coupled to the traveler such that rotation of the drive member causes rotation of the traveler relative to the housing.

Abstract: 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.
