“…1,7,[22][23][24][25] However, clinical studies on the outcomes of patients who underwent spinal fusion with the PEEK rod pedicle screw system are limited, and their results are conflicting. 14,16,27 Therefore, the purpose of the current study was to evaluate the clinical and imaging outcomes of patients who underwent spinal fusion with PEEK rod constructs for lumbar spine disease. The current results indicated improved disability and pain scores, high fusion rates, and minor complications with no adjacent segment degeneration at the time of this writing.…”

“…26 However, few clinical studies have been reported on PEEK rod pedicle screw spinal instrumentation systems, and those that were reported had small sample sizes and short-term follow-ups. 14,16,27 In addition, the reported results are conflicting; some studies reported good or excellent results with a low complication rate with PEEK rod systems, 16,27 whereas others reported a high reoperation rate with this system in patients with lumbar degenerative spine disease with no improved benefit over all-metal instrumented fusions. 14 To enhance the literature, the current article describes the authors' clinical results with the use of PEEK rods for posterior spinal fusion.…”

Few clinical studies have reported polyetheretherketone (PEEK) rod pedicle screw spinal instrumentation systems (CD-Horizon Legacy PEEK rods; Medtronic, Minneapolis, Minnesota). This article describes a clinical series of 52 patients who underwent posterior spinal fusion using the PEEK Rod System between 2007 and 2010. Of the 52 patients, 25 had degenerative disk disease, 10 had lateral recess stenosis, 6 had degenerative spondylolisthesis, 6 had lumbar spine vertebral fracture, 4 had combined lateral recess stenosis and degenerative spondylolisthesis, and 1 had an L5 giant cell tumor. Ten patients had 1-segment fusion, 29 had 2-segment fusion, and 13 had 3-segment fusion. Mean follow-up was 3 years (range, 1.5-4 years); no patient was lost to follow-up. Clinical evaluation was performed using the Oswestry Disability Index and a low back and leg visual analog pain scale. Imaging evaluation of fusion was performed with standard and dynamic radiographs. Complications were recorded. Mean Oswestry Disability Index scores improved from 76% preoperatively (range, 52%-90%) to 48% at 6 weeks postoperatively, and to 34%, 28%, and 30% at 3, 6, and 12 months postoperatively, respectively. Mean low back and leg pain improved from 8 and 9 points preoperatively, respectively, to 6 and 5 points immediately postoperatively, respectively, and to 2 points each thereafter. Imaging union of the arthrodesis was observed in 50 (96%) patients by 1-year follow-up. Two patients sustained screw breakage: 1 had painful loss of sagittal alignment of the lumbar spine and underwent revision spinal surgery with pedicle screws and titanium rods and the other had superficial wound infection and was treated with wound dressing changes and antibiotics for 6 weeks. No adjacent segment degeneration was observed in any patient until the time of this writing.

“…Few studies have documented the clinical outcomes of PEEK rods used for fusion [5]. De Iure et al [5] retrospectively reviewed 30 fusion cases in a single-cohort observational study with average follow-up of 18 months. All but one of the patients achieved satisfactory fusion, but the authors recommended longer follow up to better judge the effectiveness of PEEK rods for fusion.…”

Dynamic stabilization in a degenerate symptomatic spine may be advantageous compared with conventional fusion procedures, as it helps preserve motion and minimizes redistribution of loads at instrumented and adjacent segments. This article presents a systematic review of biomechanical and clinical evidence available on some of the pedicle screw based posterior dynamic stabilization (PDS) devices. Using Medline, Embase, and Scopus online databases, we identified four pedicle-screw-PDS devices for which both, biomechanical testing and clinical follow-up data are available: Graf artificial ligaments, Isobar TTL, Polyetheretherketone rods, and Dynesys. The current state-of-the-art of pedicle-screw-PDS devices is far from achieving its desired biomechanical efficacy, which has resulted in a weak support for the posited clinical benefits. Although pedicle-screw-PDS devices are useful in salvaging a moderately degenerate functionally suboptimal disc, for severe disc degeneration cases fusion is still the preferred choice. We conclude that a pedicle-screw-PDS device should aim at restoring load sharing amongst spinal elements while preserving the qualitative and quantitative nature of spinal motion, especially minimize posterior shift of the helical axis of motion. More precise and objective assessment techniques need to be standardized for in vivo evaluation of intervertebral motion and load sharing amongst spinal elements across different pedicle-screw-PDS devices.
