Abstract
Introduction
The Z or “scarf” osteotomy was first described by Meyer in 1926 and then by Burutaran in 1976. It was later popularised by Weil in the USA and Barouk in Europe in the 1990's and is now an accepted technique that forms part of a surgeons' armamentarium. The theory of Diffusion of Innovations was described by Rogers in 1962 to explain how novel ideas are accepted into practice across different industries, including medicine. It has never previously been used to study the adoption of ideas in foot and ankle surgery.
Methods
This paper uses publication volume as a surrogate marker for adoption, as described previously by the authors. Briefly, a systematic review of the literature was carried out. MESH headings included ‘Hallux Valgus’, and ‘osteotomy’ or ‘SCARF’ or ‘Z osteotomy’ or ‘bunionectomy’. 2818 publications were identified and the abstracts were reviewed excluding 2699 publications for non-relevance. The data was analysed by year of publication, country of origin, as well as for level of evidence.
Results
There were 120 publications relating to SCARF osteotomy, which when plotted on a graph produced an s shaped curve. 58% of publications came from Europe and 38% from the USA. There was only a single level 1 paper published in 2008.
Discussion
This study confirms that publication volume is a surrogate marker for adoption and that SCARF osteotomy became adopted by the late 2000's as indicated by the plateau on an s-shaped curve. Post market surveillance has led to a further rise in recent publications indicating that certain issues still need resolving before the laggards adopt this technique. Despite SCARF having been around for more than 80 years, very little high level evidence has been published of its effectiveness. Recommendations are made as to how future innovations should be introduced in foot and ankle surgery.
