The development of non-union following instrumented scoliosis correction may predispose to pseudarthrosis and subsequent implant failure. Although non-union is often multifactorial, it is widely accepted that bone graft of adequate quality and quantity is fundamental to achieve solid fusion. Traditionally, autologous rib graft or iliac crest harvest has been utilised for endoscopic anterior instrumented scoliosis surgery. However, these techniques increase the operative duration and cause donor site morbidity, both of which may lengthen hospital stay. Alternatives such as allograft bone and bone morphogenetic proteins have gained more widespread use and may improve fusion rates although this remains controversial. The aim of this study was to compare two-year postoperative fusion rates for a series of patients who underwent endoscopic anterior instrumentation for thoracic scoliosis utilising various bone graft types. This study demonstrated significantly better rates of thoracic fusion in endoscopic anterior instrumented scoliosis correction using mulched femoral allograft compared with autologous rib heads and iliac crest graft. This could be partly explained by the difficulty obtaining sufficient quantities of autologous graft. The lower fusion rate seen in the autologous graft group appear to predispose to rod fracture although the longer-term clinical consequence of implant failure in this group is not clear and warrants further study.

Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
