  2. Polyaxial screw - Wikipedia

    en.wikipedia.org/wiki/Polyaxial_screw

    A polyaxial screw is used for connecting vertebrae to rods in spinal surgery, particularly spinal fusion procedures. It is a type of screw whose spherical head is enclosed in a housing, which allows the screw a range of motion along several different axes relative to the housing. The ball joint allows the surgeon some flexibility in placing the ...

  3. Vertebral augmentation - Wikipedia

    en.wikipedia.org/wiki/Vertebral_augmentation

    Vertebroplasty and kyphoplasty are the two most common procedures for spinal augmentation. These medical terms are classical compounds of the suffix -plasty meaning "molding or shaping surgically" (from Ancient Greek plastós "molded, formed") and the prefixes vertebro-"vertebra" (from Latin vertebra "joint, joint of the spine") and kypho-"humped; stooping forward" (from Ancient Greek kyphos ...

  4. Vertebral fixation - Wikipedia

    en.wikipedia.org/wiki/Vertebral_fixation

    Vertebral fixation (also known as "spinal fixation") is an orthopedic surgical procedure in which two or more vertebrae are anchored to each other through a synthetic "vertebral fixation device", with the aim of reducing vertebral mobility and thus avoiding possible damage to the spinal cord and/or spinal roots.

  5. Spinal fusion - Wikipedia

    en.wikipedia.org/wiki/Spinal_fusion

    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.

  6. Robot-assisted surgery - Wikipedia

    en.wikipedia.org/wiki/Robot-assisted_surgery

    As of 2019, the application of robotics in spine surgery has mainly been limited to pedicle screw insertion for spinal fixation. [76] In addition, the majority of studies on robot-assisted spine surgery have investigated lumbar or lumbosacral vertebrae only. [ 76 ]

  7. Fixation (surgical) - Wikipedia

    en.wikipedia.org/wiki/Fixation_(surgical)

    Fixation in orthopedics is the process by which an injury is rendered immobile. [1] This may be accomplished by internal fixation , using intramedullary rod , Kirschner wire or dynamic compression plate ; or by external fixation , using a spanning external fixator , Taylor Spatial Frame or Ilizarov apparatus .

  8. Ventral slot - Wikipedia

    en.wikipedia.org/wiki/Ventral_slot

    The ventral slot technique is a procedure that allows the surgeon to reach and decompress the spinal cord and associated nerve roots from a ventral route in veterinary medicine. There are also alternative ways to open the spinal canal from dorsal by performing a hemilaminectomy, but this often gives only limited access.

  9. Pars interarticularis - Wikipedia

    en.wikipedia.org/wiki/Pars_interarticularis

    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 lamina and posterior to the pedicle. It is abnormal in spondylolysis, either due to fracture or congenitally. [1] Bilateral C2 pars fractures are known as a variant of the hangman's ...
