“…Intraobserver ICC values showed almost perfect agreement (ICC [ 0.8) for both acetabular and femoral components when using both templating methods, suggesting both methods are highly reproducible. Our ICC values correspond well to previous studies, which found ICC values ranging from 0.7 to 0.97 [6,10,15,21]. Our study showed that experience level did not have an effect on accuracy nor intraobserver variability.…”

“…However, to the best of our knowledge, no study has shown that errors in templating at the time of surgery directly leads to inferior clinical outcomes. Our study found substantial interobserver ICC value agreement for acetate templating for the femoral component and digital templating for the acetabular and femoral components, which is similar to several studies using the analog or digital templating methods [6,15]. However, values were lower than that quoted by Gamble et al [10], which found ICC values ranging from 0.8 to 0.94.…”

“…More recently with the creation of digital imaging systems, several studies have assessed the validity of digital templating and have shown good results when compared with analog templating [10,12,15]. This has added to the literature and may potentially be cost-saving by allowing the use of valid and reliable digital templating and avoiding the cost of creating printed images for templating.…”

“…The development of digital radiography and Picture Archiving and Communication Systems has in turn led to the development of digital templating software. Several studies have looked at the validity and reliability of digital templating compared with analog templating [6,10,12,15,18,25]. Digital templating has been shown to have good reliability and validity [2,6,10,12,15,18,25].…”

Digital templating has been shown to have good reliability and validity [2,6,10,12,15,18,25]. However, digital templating requires the availability of digital templating software on numerous workstations and assumes that hospital IT departments will provide timely updates of the built-in templates within the software.…”

Background Templating is an important aspect of preoperative planning for total hip arthroplasty and can help determine the size and positioning of the prosthesis. Historically, templating has been performed using acetate templates over printed radiographs. As a result of the increasing use of digital imaging, surgeons now either obtain additional printed radiographs solely for templating purposes or use specialized digital templating software, both of which carry additional cost. Questions/purposes The purposes of this study was to compare acetate templating of digitally calibrated images on an LCD monitor to digital templating in terms of (1) accuracy; (2) reproducibility; and (3) time efficiency.Methods Acetate onlay templating was performed directly over digital radiographs on an LCD monitor and was compared with digital templating. Five separate observers participated in this study templating on 52 total hip arthroplasties. For the acetate templating, the digital images were magnified to the scaled reference on the templates provided by the manufacturer (ratio 1.2:1) before templating using a 25-mm marker as a reference. Both the acetate and digital templating results were then compared with the actual implanted components to determine accuracy. Interobserver and intraobserver variability was determined by an intraclass correlation coefficient. Observers recorded time to complete templating from the time of complete upload of patients' imaging onto the system to completion of templating. Conclusions Acetate onlay templating on digitally calibrated images can be a reliable substitute for digital templating using specialized software. It is quicker to
