  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. Laminotomy - Wikipedia

    en.wikipedia.org/wiki/Laminotomy

    The percutaneous pedicle screw fixation technique allows for a procedure that presents minimal risk to the patient. Fluoroscopic image guided navigation through these portals allows for surgeons to perform more efficient procedures. Minimally invasive procedures often yield a much faster recovery time than fully invasive surgeries, making them ...

  4. Vertebral fixation - Wikipedia

    en.wikipedia.org/wiki/Vertebral_fixation

    The device used to achieve vertebral fixation is usually a permanent rigid or semi-rigid prosthesis made of titanium; examples include rods, plates, screws, and various combinations thereof. A less common alternative is the use of a resorbable fixation device, composed of a bio-resorbable material.

  5. 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 .

  6. Management of scoliosis - Wikipedia

    en.wikipedia.org/wiki/Management_of_scoliosis

    In recent years all-screw systems have become the gold-standard technique for adolescent idiopathic scoliosis. Pedicle screws achieve better fixation of the vertebral column and have better biomechanical properties than previous techniques, so enabling greater correction of the curve in all planes. [50]

  7. Computer-assisted surgery - Wikipedia

    en.wikipedia.org/wiki/Computer-assisted_surgery

    The application of robotic surgery is widespread in orthopedics, especially in routine interventions, like total hip replacement [11] or pedicle screw insertion during spinal fusion. [12] It is also useful in pre-planning and guiding the correct anatomical position of displaced bone fragments in fractures, allowing a good fixation by ...

  8. Vertebral augmentation - Wikipedia

    en.wikipedia.org/wiki/Vertebral_augmentation

    Vertebroplasty had been performed as an open procedure for many decades to secure pedicle screws and fill tumorous voids. However, the results were not always worth the risk involved with an open procedure , which was the reason for the development of percutaneous vertebroplasty.

  9. 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.
