OBJECT The authors introduce a unique computer-assisted cervical pedicle screw (CPS) insertion technique used in conjunction with specially modified original pedicle screw insertion instruments. The accuracy of screw placement as well as surgery-related outcome and complication rates were compared between two groups of patients: those in whom a computer-assisted and those in whom a conventional manual insertion technique was used. METHODS The screw insertion guiding system consisted of a…

Clinical accuracy of 3D fluoroscopy-assisted cervical pedicle screw insertion.

The authors were able to correctly insert cervical PSs using the 3D fluoroscopy and navigation system and placed screws using intraoperative acquisition of data by the isocentric C-arm fluoroscope and a computer navigation system.

Efficacy of computer-assisted pedicle screw insertion for cervical instability in RA patients

The screws in RA patients tended to be more deviated than those in non-RA patients, and in Conventional group, four screws were placed far laterally, and two (7%), far medially, while in Navigation group, no screw was placed far Laterally or medially.

Intra-operative computer navigation guided cervical pedicle screw insertion in thirty-three complex cervical spine deformities

Iso-C navigation improves the safety and accuracy of pedicle screw insertion and is not only successful in achieving secure pedicle fixation but also in identifying the best available bone stock for three-column bone fixation in altered anatomy.

Accuracy of pedicle screw insertion in the cervical spine for internal fixation using frameless stereotactic guidance.

Results may be improved by the use of intraoperative CT scanning and navigated percutaneous screw insertion, which allow optimization of the transpedicular trajectory, and there remains some risk of criticaltranspedicular screw malpositioning in the subaxial cervical spine.

Cervical pedicle screw insertion using a computed tomography cutout technique.

A new pedicle screw insertion method, called the "CT cutout" technique, is developed that can be performed with the aid of single-plane fluoroscopy and without the need of configuration and shows great promise for safe pedicle Screw insertion for the cervical spine.

Surgical safety of cervical pedicle screw placement with computer navigation system

Evaluating the safety of CPS placement using computer navigation system for posterior cervical instrumented fixation and discussing its complication avoidance and management found that image-guided CPS placement has been an important advancement to secure the safe surgery.

Revision cervical spine surgery using transarticular or pedicle screws under a computer-assisted image-guidance system

Although more advanced technology is hopeful, a computer-assisted image-guidance system with simultaneous fluoroscopy is useful for aiding revision surgery to achieve rigid fixation and ensure safety.

Screw perforation features in 129 consecutive patients performed computer-guided cervical pedicle screw insertion

Careful insertion of pedicle screws is necessary, especially at C3 to C5, even when using a CT-based navigation system, because Pedicle screws tend to be laterally perforated.

Anatomic study of individualized and improved pedicle screw implantation in the lower cervical spine.

The method of individualized and improved pedicle screw implantation in the lower cervical spine is relatively safe and reliable, which can be considered to be used in the clinic.
