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 ...
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]
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 ]
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.
A laminotomy is an orthopaedic neurosurgical procedure that removes part of the lamina of a vertebral arch in order to relieve pressure in the vertebral canal. [1] A laminotomy is less invasive than conventional vertebral column surgery techniques, such as laminectomy because it leaves more ligaments and muscles attached to the spinous process intact and it requires removing less bone from the ...
VBT uses a strong, flexible tether that is attached to screws embedded in the spine. It is important to have the surgery while the child or teen is still growing because the tether is meant to gradually change the severity of the curve as growth occurs. In addition to realigning the spine, the main benefit of VBT is that flexibility is maintained.
