Abstract
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 (XRO).
DESIGN
Retrospective analysis of consecutive patients.
SETTING
Fourteen hospitals including Level 1 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 18-89 years 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 3 observers, measuring Böhler angle (BA), crucial angle of Gissane (CAG), calcaneal length (CL), calcaneal height (CH), calcaneotalar ratio (CTR), and 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 intersubject 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.
