Background: Advances in foot and ankle arthroscopy over the last 2 decades have allowed for subtalar joint arthrodesis to be performed arthroscopically. The potential advantages of the arthroscopic technique include higher fusion rates, lower complications, reduced perioperative morbidity, and accelerated rehabilitation. Arthroscopic arthrodesis may, however, not be appropriate in the setting of complex deformity correction or the need for other open procedures. Methods: Surgical techniques of arthroscopic subtalar joint arthrodesis are described. Outcomes and complications associated with these procedures are presented, based on a comprehensive literature review. Thirteen Level IV studies of moderate quality were included. Results and Conclusion: Excellent arthrodesis union rates were achieved (average 96%, range 86%-100%), at a weighted average union time of 8.8 weeks (95% confidence interval 7.9-9.7). The overall complication rate was 21% (87/415 feet; range 10%-36.4%). Metal irritation was the most common complication (11.2%), followed by nerve injury (4.2%) and infection (0.9%). Similar fusion rates have been reported when comparing arthroscopic and open arthrodesis. Complication rates are also similar, excerpt for infection, which may be lower with arthroscopy. Three different approaches were used to access the subtalar joint with similar union and complication rates. There was no evidence that the use of bone graft or more than 1 screw improved outcomes. The superiority of arthroscopic subtalar fusion over open techniques cannot be demonstrated by the available studies. Level of Evidence: Level IV, case series.
Objectives: Surgical site infections (SSIs) are associated with increased length of hospitalization and costs. Epidemiologists and infection control practitioners, who are in charge of implementing infection control measures, have to assess the quality and relevance of the published SSI cost estimates before using them to support their decisions. In this review, we aimed to determine the distribution and trend of analytical methodologies used to estimate cost of SSIs, to evaluate the quality of costing methods and the transparency of cost estimates, and to assess whether researchers were more inclined to use transferable studies. Methods: We searched MEDLINE to identify published studies that estimated costs of SSIs from 2007 to March 2021, determined the analytical methodologies, and evaluated transferability of studies based on 2 evaluation axes. We compared the number of citations by transferability axes. Results: We included 70 studies in our review. Matching and regression analysis represented 83% of analytical methodologies used without change over time. Most studies adopted a hospital perspective, included inpatient costs, and excluded postdischarge costs (borne by patients, caregivers, and community health services). Few studies had high transferability. Studies with high transferability levels were more likely to be cited. Conclusions: Most of the studies used methodologies that control for confounding factors to minimize bias. After the article by Fukuda et al, there was no significant improvement in the transferability of published studies; however, transferable studies became more likely to be cited, indicating increased awareness about fundamentals in costing methodologies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
