Does the Current State of Evidence Justify the Broad Use of Cross-Links in Dorsal Instrumentation? A Systematic Review

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