Spinal interbody system and method

ActiveUS8216312B2Avoid expulsionLimiting reducing and limiting impactInternal osteosythesisBone implantCouplingIntervertebral disk
Embodiments of the present invention provide spinal implant systems and methods. According to one embodiment, a plate attached to one or more vertebrae can prevent expulsion of an interbody device from a disc space. The plate and interbody device can be coupled by an attachment member. According to one embodiment, the attachment member is coupled to the plate and includes a portion inserted in a threaded or non-threaded cavity. Preferably, the coupling between the plate and attachment member allows rotation in three dimensions thereby allowing the plate to rotate relative to the interbody device. This allows the plate to be better positioned for attachment to the spine during an operation.

Instrument and method for implanting an interbody fusion device

A holder is provided which couples to the spine. In an embodiment, the holder has two conduits into which sleeves may be inserted during a spinal fusion procedure. The holder may have a distractor extending from the bottom of the holder. The distractor secures the holder to the spine and maintains a proper separation distance between adjacent vertebrae. The sides of the distractor may be serrated to better secure the holder to the spine. The sleeves and conduits serve as alignment guides for instruments and implants used during the procedure. In an embodiment, the holder may include holes for fasteners that fixably secure the holder to vertebrae adjacent to a disc space. A flange may be placed around the holder to shield surrounding tissue and to provide a placement location for adjacent blood vessels during the spinal fusion procedure.

Systems, devices and methods for posterior lumbar interbody fusion

Described herein are stabilization devices, systems and methods to aid in posterior lumbar interbody fusion (PLIF) surgeries. The stabilization devices (“devices”) described herein are typically self-expanding devices that may be implanted into an intervertebral disc and packed with a bone graft or biologic or synthetic material to promote anchoring of the stabilization device and fusion of the vertebrae adjacent to the intervertebral disc.

Formed in place corpectomy device

An inflatable corpectomy device comprises a balloon, which defines a cavity for receiving a hardenable media. The device can be inserted in an un-inflated form into a space formerly occupied by a diseased or damaged vertebrae bone. When inflated with a hardenable material, the device expands and fills the space. Various bone anchors or plates can be used in combination with the inflatable device to bridge the space and stabilize the spine while the device hardens.

Implants having internal features for graft retention and load transfer between implant and vertebrae

An interbody spinal implant, such as a solid-body or composite implant, includes at least one graft contact surface as one or more of the internal surfaces of the implant. The graft contact surface, for example, having at least one ridge or groove is designed to contact and promote retention and stabilization of bone growth-inducing materials placed within the internal openings of the implant body. In addition, the ridges or grooves may influence the biological processes to promote bone healing and fusion. Also disclosed are processes of fabricating the graft contact surfaces and other surface topographies on the implant.

Spinal Interbody Distractor

A spinal interbody distractor is provided that is configured to provide distraction of adjacent vertebrae after implantation within a spinal disc cavity through manual rotation of the distractor once implanted. Such implantation is preferably, but not necessarily, through minimally invasive surgical techniques. In one form, the distractor is configured to be rotated 90° to 180° after implantation to provide distraction of adjacent vertebrae. The distractor has a lateral side to lateral side height of a first length and a superior end to inferior end height of a second length that is greater than the first length. This configuration allows the distractor to be inserted into a spinal disc cavity having an opening with a height that is smaller than an end height of the spinal disc cavity after implantation thereof, thereby providing distraction of adjacent vertebrae. The spinal interbody distractor may have one or more cavities, areas, openings and / or bores for spinal fusion material when the distractor is used as a fusion body. The spinal interbody distractor is made from a biocompatible material such as a thermoplastic (e.g. PEEK), a polymer, metal, combination thereof or otherwise, such as desired and / or is appropriate.

Composite metal and bone orthopedic fixation devices

Composite orthopedic devices that facilitate spine stabilization, such as: bone screws, rods, plates, interbodies, and corpectomy cages are disclosed. They are designed to provide both strength and load carrying capabilities, while increasing bio-integration of the devices with the surrounding bone tissue. They are constructed of composite layers of allograft and / or autograft bone and a structural material, such as titanium alloy or carbon / graphite fiber composite. Cannulations within the device are loaded with a mixture of stem cells, particles of allograft and / or autograft bone, and bone growth factors, such as BMP-2. The cannulations are connected to the surface of the device via multiple fenestrations that provide pathways to supply the bone / stem cell mixture to the surface, allowing living bone tissue to grow and insure bio-integration. The devices can also have radiofrequency (RF) stimulation implantation within the structure of the implanted device, capable of responding to external RF stimulation of enhanced bone growth.

Expandable interbody spacer

An expandable interbody spacer for the spine is provided. The spacer includes upper and lower endplates simultaneously movable with respect to a housing along an axis traverse to a longitudinal axis to increase or decrease the height of the spacer selectably along both an anterior side and a posterior side for uniform expansion / contraction of the endplates or only along the anterior side for angular expansion / contraction of the endplates. A spacer deployment instrument is provided that is selectable to effect uniform or angular expansion / contraction. When uniform expansion / contraction is selected a gear on an anterior rod is engaged with a gear on a posterior rod to simultaneously rotate both rods in opposite directions. Opposite threads on actuators of the spacer effect translation of the actuators in the same direction along the longitudinal axis.

Intervertebral inflatable distractors employing thecal sac retractors, and related systems and methods

Intervertebral inflatable distractors employing thecal sac retractors, and related systems and methods are disclosed. Adjacent vertebrae are spaced apart or distracted to prepare for the installation of intervertebral cages during spine surgery. An intervertebral inflatable distractor may include a inflatable portion having first and second inflation modes. In the lower-volume first mode, the inflatable portion may be efficiently received within the intervertebral space, then the higher-volume second mode may be used to abut against vertebrae endplates to urge them apart and thereby provide space to receive the cages. A thecal sac retractor of the intervertebral inflatable distractor may also be used to abut against the thecal sac to provide space for larger cages. In this manner, an interbody cage may be efficiently installed between vertebrae while minimizing injury to the vertebrae and the thecal sac.

Spinal fusion apparatus

An interbody spinal fusion cage for posterior interbody fusion procedures includes a superior member and an inferior member connected to each other via a joint. The joint allows the interbody spinal fusion cage to achieve lordosis even if implanted non-orthogonal to the sagittal plane. For example, the joint can be a hinge oriented non-normal to a longitudinal axis of the interbody spinal fusion cage, a polyaxial ball joint, and / or a universal joint. Complementary locking mechanisms, such as locking teeth or a ratchet-and-pawl arrangement, can be provided near the posterior ends of the superior and inferior members in order to prohibit the posterior ends of the superior and inferior members from separating from each other in situ. Bone holes can be provided in the superior and inferior members.
