| Popis: | OBJECTIVES Calcaneal fractures often require contralateral, uninjured calcaneus radiographs as a template. The purpose of this study was to establish mean values for calcaneal radiographic parameters in an uninjured urban American population and perform side-by-side comparison with respect to age, sex, laterality, and radiograph obliquity. DESIGN Retrospective analysis of consecutive patients. SETTING 14-hospitals including1 Level I trauma center. PATIENTS/PARTICIPANTS Retrospective review of >800 uninjured patients with bilateral foot and calcaneus radiographs obtained between June and December 2019 was performed. Inclusion criteria were the following: age 18 to 89 without fracture, previous foot surgical procedures, radiographic evidence of arthrosis in ankle, hindfoot, or midfoot, osteomyelitis, tumor or foot deformities. INTERVENTION The lateral radiographs were independently reviewed by three observers, measuring Bohler's Angle (BA), Crucial Angle of Gissane (CAG), calcaneal length (CL), calcaneal height (CH), calcaneotalar ratio (CTR), and radiograph obliquity (XRO). MAIN OUTCOME MEASUREMENTS The mean values of BA, CAG, CL, CH, and CTR were established. Side-by-side comparisons were completed with respect to age, sex, laterality, and XRO. RESULTS There were no statistically significant differences in side-by-side measurements of the BA, CAG, CL, or CH. XRO had significant effects on the measurements of BA, CAG, CH, and CTR. Side-by-side comparisons showed greater inter-subject variability than within subject differences. CONCLUSIONS We did not observe any differences in commonly measured calcaneal radiographic parameters. CAG is not a reliable parameter for diagnostic and operative planning purposes. We conclude that the use of contralateral calcaneus radiographs as templates for calcaneus fractures is a valid technique. LEVEL OF EVIDENCE Diagnostic Level III.
