A new hernia blocking system to prevent recurrent lumbar disc herniation: surgical technique, intraoperative findings and six-months post-operative outcomes.

Purpose: The aim of this study was to evaluate the performance and safety of a new hernia blocking system (HBS), implanted after a limited discectomy, to prevent recurrence of lumbar disc herniation.

Methods: Prospective, multicenter (6 sites), cohort clinical investigation. Thirty patients with a postero-lateral disc herniation between L4-S1 and large annular defects (> 6 mm wide), who underwent a limited discectomy and were treated with a new HBS (DISC care, NEOS Surgery S.

Health-related quality of life in patients undergoing lumbar total disc replacement: A comparison with the general population.

Objectives: In up to half of the cases, low back pain (LBP) is thought to be related to a degeneration of the lumbar disc. Lumbar total disc replacement (LTDR) emerged as an alternative to fusion, but its use and indications are still subject to debate. The purpose of this paper was to compare Health-related Quality of life (HRQOL) in patients undergoing LTDR for one or two-level degenerative disc disease (DDD) with the paired age and gender general population values and to assess functional disability and residual pain at one year after the surgical procedure.
