摘要:
A biologically implantable device including a spacer body and fasteners for fixing the spacer body in place between vertebrae, and a method for use of the device to improve intervertebral spacing and correct foraminal stenosis, and to immobilize facet joints and promote fusion of adjacent vertebrae to each other. A drill guide may be used in providing bores in the facet joints to receive the fasteners.
摘要:
Systems, methods and devices for providing stabilization between first and second vertebrae are provided. More particularly, in one form a system includes an implant configured to be positioned in a disc space between the first and second vertebrae and a freestanding plate for engagement with extradiscal surfaces of the first and second vertebrae. The system also includes an insertion instrument with an engaging portion configured to releasably engage with the implant and the plate such that the implant and plate can be positioned together relative to the first and second vertebrae. In one aspect, an angular orientation of the implant relative to the plate is adjustable when the implant and the plate are engaged by the instrument. In this or another aspect, the implant and plate are held in a contiguous relationship when engaged by the instrument. However, different forms and applications are also envisioned.
摘要:
A surgical instrument includes a first member having an inner surface and an outer surface. A second member has an inner surface and an outer surface. At least one of the inner surfaces defines at least one mating element and the outer surfaces are engageable with tissue. The members are relatively movable between a first configuration and a second configuration to space the tissue and define an opening between the members. At least one third member defines at least one mating element engageable with the at least one mating element of the inner surface such that the at least one third member is disposed within the opening. Systems and methods are disclosed.
摘要:
A spinal implant comprises an implant body extending between an anterior surface and a posterior surface, and including a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an inner surface that defines at least a first cavity and a second cavity. The cavities are oriented to implant fasteners in alignment with an oblique surgical pathway relative to a bilateral axis of a subject body and adjacent an anterior portion of an intervertebral space of the subject body. Systems and methods are disclosed.
摘要:
An intrabody implant disclosed and methods of use are disclosed. The implant has an inclined surface, forming a wedge shape having an acute angle adapted to be placed between at least 2 separated portions of a single bony structure (such as a vertebral body). In some embodiments, the implant may be used to support portions of a vertebral body that have been separated surgically as part of a pedicle subtraction osteotomy and to orient the portions at a more predictable lordotic angle.
