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 ...
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]
For spinal fusion surgery on AIS cases, with instrumentation attached using pedicle screws, complication rates were reported in 2011 as transient neurological injuries between 0% to 1.5%, a pedicle fracture rate of 0.24%, screw malposition assessed by radiography at 1.5%, 6% when assessed by CT scans though these patients were asymptomatic not ...
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 ...
Pedicle of vertebral arch, the segment between the transverse process and the vertebral body, and is often used as a radiographic marker and entry point in vertebroplasty and kyphoplasty procedures; Pedicle of a skin flap (medicine) Hilum of kidney, also called the renal pedicle; Pedicel, a foot process of a some cells
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.
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 ]
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 ...
