Abstract

Posterior spinal instrumentation and fusion (PSIF), with bone grafting, is the most accepted surgical treatment in Adolescent Idiopathic Scoliosis (AIS). Many different options are used as a bone graft, but the difference in the rate of infection and pseudoarthrosis has not been fully documented. This study aimed to compare the outcomes of the use of the allograft in adolescent idiopathic scoliosis (AIS) compared to no graft or autograft alone. A literature search was performed in PubMed, EMBASE, CINAHL, CENTRAL, and Web of Science, using the set inclusion/extrusion criteria. A meta-analysis was performed on select articles with RevMan TM (Review Manager 5) software. Six studies were included for each outcome. In total, the odds of getting a pseudoarthrosis if allograft was used were 1.1 (95% CI: 0.41, 3.09) times the odds of getting a pseudoarthrosis if allograft was not used, which was not statistically significant (p = 0.81). The odds of getting an infection if allograft was used were 1.2 (95% CI: 0.33, 4.72) times the odds of getting an infection if allograft was not used, which was not statistically significant (p = 0.74). There is limited evidence to either strongly support using, or not using allograft bone graft for posterior spinal fusion in cases of AIS when compared to the use of autograft alone or no graft.
