Abstract

Prior studies have suggested that biomodels enhance patient education, pre-operative planning and intra-operative stereotaxy, however the usefulness of biomodels compared to regular imaging modalities such as x-ray, CT and MR has not been quantified. (1) The aim of this study was to quantify surgeons’ perceptions on the usefulness of biomodels compared to standard visualisation modalities for pre-operative planning and intra-operative anatomical reference. Surgeons reported that the use of biomodels reduced operating times in 23 (89%) cases by a mean of 63 minutes per case (range 0–180mins) which included 8% (range 0-125mins) in tumour patients and 22% (range 30-180mins) in deformity procedures, and therefore surgical costs were often subsequently reduced despite the additional cost of the biomodel. In all cases, the surgeons reported the model had a positive effect on the outcome of the surgical procedure and that they would order a biomodel again should a similar case present. This study supports physical biomodelling as a useful, and sometimes essential tool in the armamentarium of imaging techniques used for complex spinal surgery.

Search Google Scholar™

Citation countsare sourced monthly from Scopus and Web of Science® 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.
