| Summary: | Introduction: There has been a global trend towards individually packaged screws for orthopaedic operations. Traditional practice makes use of screw caddies that require re-sterilization. Individually wrapped screws (IWS) are purported to decrease infection rates and avoid the deleterious effects of repeated screw sterilizations, despite marginal evidence. This review aimed to evaluate the safety, effectiveness and economics of screw caddies with IWS. Material and methods: The literature was surveyed in a systematic fashion between 1998 and 2017 and all relevant health technology assessments, systematic reviews, meta-analyses, randomized controlled trials, cohort studies, case-controlled studies and case series were sought. Any benefits or otherwise of IWS over screw caddies were then evaluated in the areas of safety, effectiveness and economics. Results: Two level III-3 papers suggested the use of caddies at least as safe as individual screws. Four level III-2 papers demonstrated that screws from caddies were as effective as individual alternatives, while a level III-3 paper reported that individual screws were significantly more expensive than screw caddies. Cost increases to our regional health service from ankle open reduction and internal fixations alone of at least $50,112 (AUD) per annum were calculated. Conclusions: From the results obtained, the authors recommend the continued use of screw caddies for orthopaedic procedures.
