Unlike standard lateral mass plate and screw systems, the new cervical polyaxial screw and rod system easily accommodates severe degenerative cervical spondylosis and curvatures. This instrumentation system allows for polyaxial screw placement with subsequent multiplanar rod contouring and offset attachment. [1]
X-ray of interbody fusion cage in cervical vertebrae, Juliet system. X-ray of interbody fusion cage in L5S1 vertebrae. An interbody fusion cage (colloquially known as a "spine cage") is a prosthesis used in spinal fusion procedures to maintain foraminal height and decompression. They are cylindrical or square-shaped devices, and usually threaded.
Spinal fusion, also called spondylodesis or spondylosyndesis, is a surgery performed by orthopaedic surgeons or neurosurgeons that joins two or more vertebrae. [1] This procedure can be performed at any level in the spine (cervical, thoracic, lumbar, or sacral) and prevents any movement between the fused vertebrae.
At the midline of the vertebral laminae, a drill is used to cut the bone. The lateral sides of the laminae serve as a hinge that allows expansion of the spinal canal. Specifically, the inner cortex of the lateral portion was part of the hinge. An artificial spacer is used to keep the opening fixed. One common spacer that is used is ...
SpineGuard products prepare the pilot hole for pedicle screw placement during spine surgery. [9] The PediGuard probes address various spine pathologies and surgical approaches. [10] [11] The PediGuard probe is FDA-cleared [4] [12] and CE-marked, [4] but it is not cleared for use in the cervical spine by the FDA in the US. [2]
Cervical vertebra. The pars interarticularis, or pars for short, is the part of a vertebra located between the inferior and superior articular processes of the facet joint. [1] [2] In the transverse plane, it lies between the lamina and pedicle. In other words, in the axial view, it is the bony mass between the facets that is anterior to the ...
Anterior cervical discectomy and fusion (ACDF) is a surgical procedure to treat nerve root or spinal cord compression by decompressing the spinal cord and nerve roots of the cervical spine with a discectomy, followed by inter-vertebral fusion to stabilize the corresponding vertebrae. [1]
Stereotactic surgery is a minimally invasive form of surgical intervention that makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc.
