Carbon Fiber-Reinforced PolyEtherEtherKetone (CFR-PEEK) Instrumentation in Degenerative Disease of Lumbar Spine: A Pilot Study.

CFR-PEEK is gaining popularity in spinal oncological applications due to its reduction of imaging artifacts and radiation scattering compared with titanium, which allows for better oncological follow-up and efficacy of radiotherapy. We evaluated the use of these materials for the treatment of lumbar degenerative diseases (DDs) and considered the biomechanical potential of the carbon fiber in relation to its modulus of elasticity being similar to that of bone. Twenty-eight patients with DDs were treated using CRF-PEEK instrumentation.

Percutaneous Cement Discoplasty in Degenerative Spinal Disease: Systematic Review of Indications, Clinical Outcomes, and Complications.

Background: Percutaneous cement discoplasty (PCD) is a minimally invasive surgical procedure that can provide a segmental stabilizing and indirect decompression effect in the case of severely degenerated discs characterized by vacuum phenomenon. This systematic review aims to analyze the available literature relating to correct indications and clinical and radiologic efficacy of PCD in patients affected by advanced degenerative spine conditions.

Methods: The search was conducted according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guideline.
