Abstract

Implant systems in some embodiments such as midline incision implant systems may generally include an insertion guide assembly and a plate, which define fixation trajectories. In other embodiments such as a percutaneous implant system may generally include a first a plate, an insertion guide, and a separate second insertion guide, which define fixation trajectories. Surgical methods include use of the implant systems with the plates, and use of plates alone, for installing bone fusion systems.

This application is also related to U.S. patent application Ser. No. 16/273,567 filed Feb. 12, 2019, entitled “Bone Fusion Device, System And Methods,” which application is a continuation of International Application No. PCT/US2017/047035 filed on Aug. 15, 2017, entitled “Bone Fusion Device, System And Methods” and published under the PCT Articles in English as WO 2018/035175 on Feb. 22, 2018, which application claimed priority from U.S. provisional application No. 62/375,114 filed Aug. 15, 2016, entitled “Bone Fusion Device, System And Methods,” each of which applications is incorporated herein by reference in its entirety. FIELD OF THE INVENTION The present disclosure relates generally to general surgery, orthopaedic and neurosurgical implants used for insertion within a patient's vertebrae. More specifically, but not exclusively, the present disclosure related to implant systems having a plate or an implant operable with insertion guides for establishing screw trajectories in a patient's spine. The plate or implant may also be operable in a bone fusion system with fixations elements and devices such as screws to maintain or re-establish proper spacing and alignment of a patient's spine. As used herein the term plate, implant, body, member may be used interchangeably and are not to be limiting. BACKGROUND OF THE INVENTION Spinal deformities may result from disease, age, or trauma causing destabilization of the spine. To correct destabilization of a patient's spine, fusion devices and systems may be used. Posterior lumbar spinal fusion with pedicle screws is the most common way to fuse a patient's spine. However, the pedicle screw fusion and surgical technique used for these fusions has not changed in the last 30 to 40 years. Moreover, the large number of necessary parts and pieces involved to complete these fusions increases risk, surgical time, potential for construct failure, and cost. When a patient presents with a spondylolisthesis or a displacement of a spinal vertebra in relation to the vertebra below, which needs to be fixed prior to inserting stabilization devices, for example, screws. Thus, improved fusion and/or fixation devices, systems and instrumentation are needed. SUMMARY OF THE INVENTION Aspects of the present disclosure provide bone fusion devices, systems, instruments and methods of using the same. Shortcomings of the prior art are overcome and additional advantages are provided through the provision in one embodiment of an insertion guide assembly for use in implanting a plate in an anatomical structure. The insertion guide assembly includes, for example, an insertion guide having a body with a first portion and a second portion. The second portion has a plate engaging portion. A passageway extends through the first portion, the second portion, and opens onto the plate engaging portion with the passageway defining a longitudinal axis. The body defining a first guide passageway with a first guide trajectory extending from the first portion to the second portion and opening onto the plate engaging portion. The body defines a second guide passageway with a second guide trajectory extending from the first portion to the second portion and opening onto the plate engaging portion. A plate holder is extendable through the passageway of the body from the first portion to the second portion. The plate holder has a distal end engageable with the plate to secure the plate to the plate engaging portion of the second portion of the body. The plate holder has a passageway aligned with the passageway of the body. A docking pin is extendable through the passageway of the plate holder and extendable through the plate. In another embodiment, a plate includes, for example, a body having a first surface and a second surface, a first opening at a first end of the body extending from the first surface to the second surface, a second opening at a first end of the body extending from the first surface to the second surface, a third opening positioned between the first opening and the second opening and extending from the first surface to the second surface, and the first surface defines a first boss extending around at least a portion of the first opening, and the first surface defines a second
