Analysis of Missed Skeletal Injuries Detected Using Whole-Body Bone Scan Applied to Trauma Patients: A Case–Control Study

(1) Background: Skeletal injuries may be missed in patients presenting multiple traumas during initial assessment. A whole-body bone scan (WBBS) may aid the detection of missed skeletal injuries, but the current level of research in this regard is insufficient. Thus, this study aimed to investigate whether a WBBS is useful for the detection of missed skeletal injuries in patients with multiple traumas. (2) Methods: This retrospective, single-region, trauma center study was conducted at a tertiary referral center from January 2015 to May 2019. The rate of missed skeletal injuries detected via WBBSs was evaluated, and factors that could influence the outcome were analyzed and divided into missed and not-missed groups. (3) Results: A total of 1658 patients with multiple traumas who underwent WBBSs were reviewed. In the missed group, the percentage of cases with an Injury Severity Score (ISS) ≥ 16 was higher than the not-missed group (74.66% vs. 45.50%). The rate of admission route through surgery and embolization was high in the missed group. Moreover, the proportion of patients that experienced shock in the missed group was higher than that in the not-missed group (19.86% vs. 3.51%). In univariate analysis, ISS ≥ 16, admission route through surgery and embolization, orthopedic surgery involvement, and shock were related to missed skeletal injuries. ISS ≥ 16 was determined to be statistically significant in multivariate analysis. Additionally, a nomogram was constructed based on multivariable analysis. (4) Conclusions: Missed skeletal injuries were significantly associated with several statistical factors, and a WBBS can be used as a screening method to detect missed skeletal injuries in patients with multiple blunt traumas.
