A system for correcting scoliosis, the system comprising: a bone screw configured to be screwed into a bone having: an exterior casing; a head having interior threads; a distalmost tip configured to be driven into the bone; a shaft extending between the head and the tip, the shaft having exterior threads; a magnetic ball; an interior cavity within the bone screw configured to house the magnetic ball; a cap having: a top end having a recess configured to receive a means for driving the bone screw into the bone; and a bottom end having cap threads; wherein an association of the cap threads with the interior threads causes the cap to be sealed to the head, and thus causes the magnetic ball to be fully encased within the bone screw, such that no portion of the magnetic ball is exposed outside of the exterior casing; and a correction abacus.

A bone fastener assembly instrument that can assemble a two-component bone fastener during surgery is provided. The bone fastener may be of a type that comprises a threaded bolt and nut for securing an implantable device to bone, such as a spinous process. A method for using the bone fastener assembly instrument is also provided.

A surgical screw configured to expand and prevent or minimize bone growth inside of the surgical screw is provided. Accordingly, the surgical screw is configured to increase the purchase of the surgical screw with respect to the bone, but also to be withdrawn from the bone without damaging the bone as a result of bone ingrowth. The surgical screw includes a center post with an inner bore and an outer sleeve concentric to the center post. An outer surface of the outer sleeve includes a thread to engage bone. The outer sleeve includes a cut pattern defining an expandable region configurable between a first state with a first radius measured from a longitudinal axis of the surgical screw to the outer surface and a second state having a second radius measured from the longitudinal axis to the outer surface.

Provided herein is an interspinous stabilization device, including: a central connection portion, a first side wing, a second side wing, a third side wing, and a fourth side wing. The first side wing extends from the central connection portion in a first direction. The second side wing extends from the central connection portion in the first direction. The third side wing extends from the central connection portion in a second direction opposite to the first direction. The fourth side wing extends from the central connection portion in the second direction. The central connection portion has at least one thread hole. The thread hole extends in a third direction substantially perpendicular to the first direction. The first side wing, the second side wing, the third side wing, and the fourth side wing each have a through hole.

The shim-type implant for distraction and fusion of cervical facet joints is provided. The implant has a generally box-like shape with a blunt leading edge that may be centered or offset to the inferior face. The implant may include a graft window for enhanced osseous through-growth after implantation. The implant is coated with hydroxyapatite (HA) and/or tri-calcium phosphate (TCP) to allow for osteo-conduction, is porous, and has a roughened surface with serrations on the superior and inferior faces. The implant may be fabricated from a titanium or tantalum alloy. In an embodiment, a set of tools is provided with a chisel and one or tongs and one or more decorticators for inserting the implant.

Systems for the minimally invasive repair, stabilization and/or fixation of a fractured bone, such as a rib, are disclosed. The systems include one or more rods/support members that are designed to extend along a dimension of a bone being repaired and secure the fractured bone. The support members can be photodynamic and are formed using an expandable member that is filled with a light-sensitive liquid that is cured to form the rigid support member. Two or more clamps are used to secure the support member(s) to the rib or other bone. Minimally invasive surgical methods for securing the systems to a fractured bone are also disclosed.

An apparatus for maintaining spacing of a cutout portion of lamina used for patient-customized laminoplasty is proposed. The apparatus for maintaining spacing of a cutout portion of lamina used for patient-customized laminoplasty includes a spacer configured to be fitted in a cutout space secured by opening in order to open a cutout portion and expand a spinal canal after a portion of a lamina of a vertebra is cut, and configured to keep the spinal canal expanded, and a plate coupled to the spacer and fixed to an outer side of the lamina, thereby preventing movement of the spacer.

A system and method for providing a spinal implant having a main body, a proximal anchor, a distal anchor, and an internal plunger. The proximal anchor comprises a nut having an internal bore. The distal anchor comprises a plurality of wings having a first closed configuration and a second open configuration. The internal plunger is housed within a central bore of the main body. The distal end of the internal plunger is operatively connected to the first wing and the second wing to selectively move the wings between the first closed configuration and the second open configuration, and vice versa.

Spinal implants for limiting flexion of the spine are implanted between a superior spinous process and an inferior spinous process or sacrum. The implants include upper straps which are placed over the upper spinous process, while the lower portions of the implant are attached to the adjacent vertebra or sacrum. The attachments may be fixed, for example using screws or other anchors, or may be non-fixed, for example by placing a loop strap through a hole in the spinous process or sacrum.

A spinal treatment system includes a constraint device having an upper tether portion, a lower tether portion and a compliance member coupled therebetween. The upper tether portion is coupled with a superior spinous process of a spinal segment in a patient and the lower tether portion is coupled with an inferior spinous process or sacrum of the spinal segment. The length or tension in the constraint device is adjustable so that the construct of the tether portions and the compliance member provides a force resistant to flexion of the spinal segment. The system also includes a first prosthesis coupled with the spinal segment, wherein the constraint device modulates loads borne by the prosthesis or by tissue adjacent thereto.
