- Abstract
<bold>Background: </bold>Spinal fusion surgery has become one of the most common spinal procedures during the recent years. Searching for an optimum structural stability of the vertebral interspace, surgical implants which can be inserted via a posterior lumbar interbody fusion (PLIF) approach have been enhanced recently.<bold>Objective: </bold>Evaluation of safety and efficacy of a novel PLIF polyetheretherketone (PEEK) interbody cage (TWIST) with an impactionless insertion technique.<bold>Methods: </bold>Surgical outcome in 15 patients treated with the new system were observed preoperatively, one and three years after surgery using the Oswestry Disability Index (ODI), a Visual Analogue Scale (VAS) for pain and radiological outcome analysis of fusion success.<bold>Results: </bold>Fifteen patients (7 female, 8 male) were included in the test series. After three years ODI and VAS were significantly improved. The pain intensity was reduced by more than 75% after one year and after 3 years, pain intensity was about 60% below the initial situation. The Oswestry values (ODI) improved significantly in all patients after 3 years. The fusion evaluation showed a fusion success in 87% of the patients.<bold>Conclusion: </bold>The clinical and radiological results of this first series give a positive standing and important information on the efficacy and safety over 3 years. The follow-up checks with imaging techniques showed that the fusions were very successful and functional outcome as well as pain reduction were increased.
