Abstract:
Cross-links increase the stability of screw-rod systems in biomechanical testing. The aim of this systemic review was to find evidence pertaining to the additional benefit of the implantation of cross-links in clinical practice in regard to different spinal diseases. Therefore, a systematic literature analysis of two online databases was performed according to the PRISMA statement. Inclusion criteria were prospective and retrospective studies investigating the use of cross-links in dorsal instrumentation. Biomechanical studies and case series were excluded. A total of seven retrospective studies remained for final full-text evaluation. In total, two studies each address the use of cross-links in adolescent idiopathic scoliosis, neuromuscular scoliosis or atlantoaxial fusion, one study in congenital scoliosis. In atlantoaxial fusion the additional use of cross-links may provide earlier bony fusion. In surgical treatment for pediatric scoliosis the additional use of cross-links does not provide additional benefit. Radiological outcome and complication rate did not differ in between groups. No study addressed the use of cross-links in short- or long-segment fusion due to degenerative or traumatic disorders of the spine. There is a deficiency in published literature towards the impact of cross-links in spinal surgery. The current clinical evidence data do not confirm the biomechanical advantages of cross-links in clinical practice. Further studies are needed to warrant the use of cross-links in the future.
