A distraction method including inserting a spacer element into a space between bones to be distracted, removing the spacer element from the space, inserting a wider spacer element into the space, and removing the wider spacer element from the space.

Method of distracting vertebral bones

An orthopedic device set, including: a plurality of intervertebral spacer elements, each spacer element having a different axial thickness from each other element, the axial thicknesses being selected to increase by an increment from one element to another; and an instrument for holding ones of the intervertebral spacer elements, the instrument comprising a shaft having a distal end, a selectively grasping subassembly for alternatively rigidly holding each spacer element at the distal end so that the spacer element cannot move relative to the instrument, and releasing the spacer element.

Instruments for reorienting vertebral bones for the treatment of scoliosis

An instrument for holding an intervertebral spacer includes a shaft having a proximal end forming a handle, and a distal end forming a claw subassembly for holding the spacer; the claw subassembly including a first pincer which is fixed at the distal end of the shaft and a second pincer which is selectively rotateable into and out of spacer holding association with said first pincer to hold and release, respectively, the spacer. The instrument includes an actuation mechanism for selectively rotating the second pincer, wherein the first and second pincers have opposing inner curved surfaces that extend to a distal end of the instrument.

Insertion tool for use with intervertebral spacers

A porous metal intervertebral spacer having at least one angled through hole extending from the side of the implant to a surface which interfaces with a vertebral body end plate such that an interference screw may be driven through the implant and into the bone, thereby securing the implant from undesired motion. In particular, the through holes are tapered to receive a screw and coupling element therethrough such that once fully seated, the screw is locked to the implant by virtue of a coupling element-through hole mutually tapered nesting. The head of the screw is round, as is the interior of the coupling element, thereby allowing the screw to be inserted at various angles relative to the hole without interfering with the proper seating of the coupling element in the through hole.

Porous interbody fusion device having integrated polyaxial locking interference screws

An intervertebral spacer device having a pair of opposing plates for seating against opposing vertebral bone surfaces, separated by at least one force restoring element. The preferred force restoring mechanism is a wave washer. In a first embodiment the wave washer is ring-shaped. In a second embodiment the wave washer is spiral-shaped.

Intervertebral spacer device having a wave washer force restoring element

An orthopedic spacer device comprising a spacer body having an external surface that includes at least two relative angle designation marks such that a rotational angle of the spacer body relative to a known reference is determinable.

Trial intervertebral distraction spacers

An orthopedic device set includes a plurality of intervertebral spacer elements, an instrument for holding the spacer elements during the insertion and removal thereof into and out from between adjacent vertebral bones, and a tool which facilitates the loading and unloading of the spacer elements into and out of the instrument. The tool includes a handle and a bifurcated end having a pair of similarly curved tines. The bifurcated end is engageable with each spacer element during the loading and unloading of the spacer element.

Vertebral bone distraction instruments

An instrument for insertion, implanting, and removing a cylindrical intervertebral spacer member having a deep circumferential groove, including: a shaft having a proximal end and a distal end, said proximal end forming a handle and the distal end forming a spacer member engaging subassembly; said spacer member engaging subassembly including at least one selectively expanding and contracting enclosure into which a central core of the spacer member may be introduced when the engaging subassembly is in the expanded state, and which holds the spacer member so that it cannot move when the selectively expanding and contracting enclosure is rendered into the contracted state; and an actuating mechanism, extending from the proximal end to the distal end, by which the spacer member engaging subassembly may be selectively expanded and contracted.

Insertion tool for use with tapered trial intervertebral distraction spacers

A surgical treatment for restoring proper anatomical spacing and alignment to vertebral bones including: determining an angular misalignment associated with adjacent vertebral bones; sequentially inserting and removing a series of progressively wider spacer elements into the corresponding intervertebral space between the adjacent vertebral bones until the proper anatomical spacing between the adjacent vertebral bones is restored; for each intervertebral space, inserting a tapered porous spacer element into the intervertebral space between the corresponding adjacent vertebral bones; rotating the tapered porous spacer element such that the rotational orientation of the tapered porous spacer element introduces the appropriate counter offset to the intervertebral space of the previously misaligned scoliotic vertebral bones, thereby restoring the proper anatomical alignment of the vertebral bones; and stabilizing the adjacent vertebral bones to permit infused growth of bone into the tapered porous spacer element.

Surgical method of treating scoliosis

A screw and coupling element assembly for use with an orthopedic rod implantation apparatus includes a screw with a head and a shaft extending from the head, a coupling element with a seat within which the head is seatable such that the shaft protrudes from the coupling element, and a locking element mateable with the coupling element and when mated is selectively movable through a plurality of positions including unlocked and locked positions. When in the unlocked position, the locking element presents a rod-receiving channel and the head is movable in the seat such that the shaft is directable in a plurality of angles relative to the coupling element. When in the locked position, a rod disposed within the rod-receiving channel is fixed relative to the coupling element and the head is immovable in the seat such that the shaft is fixed at an angle relative to the coupling element.

Polyaxial pedicle screw having a rotating locking element

A surgical treatment for restoring a proper anatomical spacing and alignment to vertebral bones of a scoliosis patient, the treatment including determining an angular misalignment associated with at least one pair of adjacent bones, adjusting the intervertebral space between adjacent vertebral bones to restore proper spacing, and inserting a tapered spacer to restore proper anatomical misalignment of the vertebral bones.

Method of surgically treating scoliosis

Orthopedic device set for reorienting vertebral bones for the treatment of scoliosis

A surgical treatment for distracting vertebral bodies to their proper anatomical spacing including sequentially inserting and removing a series of progressively wider cylindrical spacer elements into the intervertebral space between adjacent vertebral bones until the distance between the vertebral bones is anatomically appropriate.

An intervertebral space distraction and implantable device assembly provides sequentially axially wider spacers that are to be sequentially inserted into and removed from an intervertebral space to widen the space until a desired anatomical spacing of the adjacent vertebral bones is restored. The set of spacers includes a porous spacer that is as wide as the spacer that restores the desired anatomical spacing. The porous spacer can therefore be left implanted in the intervertebral space to promote fusion of the adjacent vertebral bones.
