Abstract

A bone plate having one or more screw holes configured to receive a coupling screw to attach the bone plate to a spacer, anchor holes configured to receive anchors or bone screws to attach the bone plate to one or more vertebral bodies, one or more blocking screws configured to allow passage of the bone screws into the plate body and to lock the bone screws in the plate body after passage, and a port to rigidly attach the bone plate to an inserter instrument. The bone plate allows rigid connection to a spacer that is implanted between adjacent vertebral bodies. The plate body may include one or more anchor holes.

Claims (10)

  1. 1 . A method of treating a spine for fusing adjacent vertebral bodies, said method comprising: preparing a disc space between the adjacent vertebral bodies; providing a spinal fixation system including: a bone plate having a screw hole, one or more anchor holes, a blocking screw for each of the anchor holes, and a port; a spacer configured to attach to the bone plate via a coupling screw threaded into the screw hole; and a bone fixation device configured to be inserted into each of the anchor holes to fixate the bone plate to one or more of the adjacent vertebral bodies, inserting the spacer into the disc space; attaching the bone plate to the spacer; and fixating the bone plate to one or more of the adjacent vertebral bodies.
  2. 2 . The method of claim 1 , wherein an underside of the bone plate contains a toothy ridge configured to engage one of the adjacent vertebral bodies.
  3. 3 . The method of claim 1 , wherein an underside of the bone plate contains a cutout configured to receive a portion of the spacer.
  4. 4 . The method of claim 1 , wherein an underside of the bone plate contains one or more prongs that are received in a portion of the spacer.
  5. 5 . The method of claim 1 , wherein the port is threaded.
  6. 6 . The method of claim 5 , wherein the port is configured to receive a threaded end of an inserter instrument.
  7. 7 . The method of claim 1 , wherein each blocking screw is configured to rotate from a first position to a second position to lock one bone fixation device to the bone plate.
  8. 8 . The method of claim 1 , wherein each bone fixation device is a bone screw.
  9. 9 . The method of claim 1 , wherein each bone fixation device is a shim.
  10. 10 . The method of claim 1 , further comprising an inserter configured to attach to the bone plate via the port.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This patent application is a divisional of U.S. application Ser. No. 18/317,956, filed May 16, 2023, the entire contents of each is incorporated herein by reference. FIELD The present disclosure relates to stable fixation of spine segments, allowing for fusion in, e.g., skeletally mature patients. More particularly, the disclosure relates to a bone fixation plating device that can be affixed to vertebrae of a spine and to a spacer inserted between adjacent spine segments. The invention also relates to a method for delivering and implanting the bone fixation plating device. BACKGROUND Bones and bony structures are susceptible to a variety of weaknesses that can affect their ability to provide support and structure. Weaknesses in bony structures can have many causes, including degenerative diseases (e.g., degenerative disc diseases), tumors, fractures, dislocations and failed previous fusions. Some of these weaknesses can cause further conditions such as spondylolisthesis wherein bony structures slip out of their proper position. In some cases of spinal surgery, it is known to use bone fixation plating devices (e.g., bone plate systems and rod and screw systems) to improve the mechanical stability of the spinal column and to promote the proper healing of injured, damaged or diseased spinal structures. Typically, corrective surgery can entail the removal of damaged or diseased tissue, a decompression of one or more neural elements, followed by the insertion of an interbody implant or bone graft for the purposes of a fusion or disc arthroplasty. In cases where spinal fusion is the desired surgical outcome, the surgery can often include implanting a bone plate or rod and screw system in order to immobilize adjacent vertebral bones to expedite osteogenesis across the vertebral segments. Lateral lumbar interbody fusion (LLIF) and oblique lumbar interbody fusion (OLIF) are two types of minimally invasive spine fusion surgery in which surgeons access the spinal column through a lateral retroperitoneal approach. Diseased spinal discs are removed and supplemented with interbody devices to restore lost disc height and angle, as well as to provide stability so the segment can fuse and reduce nerve pain and discomfort. Stability of a spinal segment is critical for a successful fusion, and various types of implants can be used to facilitate fusion. Plates have been used frequently for stabilization in the lumbar spine. Plating is often used in conjunction with spinal fusion to add stabilization to the segment. However, vertebrae and different surfaces on those vertebrae have varying shapes which causes variation in the desirable plate contour and screw trajectory. Improper placement and fit of a plate onto the vertebral bodies can weaken fixation and can also cause damage to the surrounding soft tissue and vasculature. Additional issues include intra-operative movement in a plate during intra-operative placement and screw prep and to assist in the reduction of migration for the implant's life. There also exists a need for means of data collection on the forces in the segment allow for aid in placement intra-operatively and for patient monitoring post-operatively. Accordingly, there is a need for a lateral plate that can be secured to vertebral bodies to reduce segment motion and promote stability. There is a need for a plate that can also be attached directly to the interbody to further reduce motion to decrease the likelihood of implant migration while further optimizing fusion potential. SUMMARY In accordance with the present disclosure, a spinal fixation system for fusion of adjacent vertebral bodies including a bone plate having a screw hole, one or more anchor holes, a blocking screw for each of the anchor holes, and a port. The spinal fixation system further includes a spacer to attach to the bone plate via a coupling screw threaded into the screw hole and a bone fixation device to be inserted into each of the anchor holes to fixate the bone plate to one or more of the adjacent vertebral bodies. In accordance with the present disclosure, a method of treating a spine for fusing adjacent vertebral bodies, the method including preparing a disc space between the adjacent vertebral bodies and providing a spinal fixation system. The spinal fixation system including a bone plate having a screw hole, one or more anchor holes, a blocking screw for each of the anchor holes, and a port. The spinal fixation system further includes a spacer to attach to the bone plate via a coupling screw threaded into the screw hole and a bone fixation device to be inserted into each of the anchor holes to fixate the bone plate to one or more of the adjacent vertebral bodies. The method further including inserting the spacer into the disc space, attaching the bone plate to the spacer, and fixating the bone plate to one or more of the adjacent vertebral bodies.
