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 ...
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 ...
Postoperative wounds are those wounds acquired during surgical procedures. Postoperative wound healing occurs after surgery and normally follows distinct bodily reactions: the inflammatory response, the proliferation of cells and tissues that initiate healing, and the final remodeling.
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
If the defect is at the nasal tip, or at the nasal dorsum, the pedicle is based laterally. An ideal location for the second flap is along the junction of the nasal dorsum and the lateral nasal wall. The nasal wound is cut and shaped into a teardrop form, by the cutting out of a Burrow's triangle of flesh on the side of pedicle base.
Neuronavigation is recognized as the next evolutionary step of stereotactic surgery, a set of techniques that dates back to the early 1900s and that gained popularity during the 1940s, particularly in Germany, France and the U.S., with the development of surgery for the treatment of movement disorders such as Parkinson's disease and dystonias.
External fixation is a surgical treatment wherein Kirschner pins and wires are inserted and affixed into bone and then exit the body to be attached to an external apparatus composed of rings and threaded rods — the Ilizarov apparatus, the Taylor Spatial Frame, and the Octopod External Fixator — which immobilises the damaged limb to facilitate healing.
