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.



Accuracy of pedicle screw insertion with and without computer assistance: a randomised controlled clinical study in 100 consecutive patients

In conclusion, pedicular screws were inserted more accurately with image-guided computer navigation than with conventional methods.

Pedicle Screw Placement Using Image Guided Techniques

Results show that a computer assisted technique is much more accurate and safe than manual insertion in treating fractures, spondylolisthesis, or pseudarthrosis and in patients with scoliosis, four screws in four vertebrae had incorrect placement.

Computer-assisted surgery in posterior instrumentation of the cervical spine: an in-vitro feasibility study

C1/2 transarticular screws as well as transpedicular screws in the cervical spine can be applied safely and with high accuracy using a computer-assisted surgery (CAS) system in vitro, and may be used in a clinical setting, as it offers improved accuracy and reduced radiation dose for the patient and the medical staff.

Improved Accuracy of Pedicle Screw Insertion With Computer-Assisted Surgery: A Prospective Clinical Trial of 30 Patients

The accuracy of pedicle screw placement using computer-assisted surgery proved to be superior to the accuracy obtained when using conventional techniques.

Computer‐Aided Pedicle Screw Placement Using Frameless Stereotaxis

Computer‐aided pedicle screw instrumentation is feasible and better overall accuracy was obtained when surface matching was used in combination with these points, and further technical points require clarification before widespread use is possible.

Complications of Pedicle Screw Fixation in Reconstructive Surgery of the Cervical Spine

The incidence of the clinically significant complications caused by pedicle screw insertion was low and can be minimized by sufficient preoperative imaging studies of the pedicles and strict control of screw insertion.

Accurate pedicle screw insertion under the control of a computer-assisted image guiding system: Laboratory test and clinical study

A commercially available computer-assisted navigation system (StealthStation; Sofamor Danek, Memphis, TN, USA) used in both an in-vitro and a clinical study performed in 1996–1998 achieved satisfactory results both in the laboratory and in a clinical setting.

Computer Assisted Spine Surgery

A computer assisted method is proposed that enables the surgeon to place a screw at a position preoperatively defined in 3 dimensions using computed tomography images and shows that an accuracy of less than 1 mm can be obtained.

Pedicle Screw Fixation for Nontraumatic Lesions of the Cervical Spine

Pedicle screw fixation is a useful procedure for posterior reconstruction of the cervical spine, and should be especially valuable for simultaneous posterior decompression and fusion.

Correction of cervical kyphosis using pedicle screw fixation systems.

Cervical kyphosis in 30 patients was effectively corrected using a pedicle screw fixation procedure with no serious complications.
