Background and Objectives: Type II odontoid fractures (T2OF) are the most prevalent cervical spine injuries among the elderly. Nonetheless, there are insufficient data regarding the influence of frailty on outcomes for both nonoperative and operative treatment approaches. We sought to evaluate the influence of frailty on outcomes using 5-factor modified frailty index.
Methods: We performed a retrospective review of the American College of Surgeons Trauma Quality Improvement Program database from 2015 to 2020. We analyzed nonoperative and operative traumatic T2OF cases. Outcomes included major complications, hospital length of stay (LOS), nonhome discharge (NHD), mortality rates, and survival probabilities. We used unmatched and propensity score-matched risk-adjusted models to assess the association between frailty and all outcomes. Survival probabilities were examined using Kaplan-Meier plots, stratified by frailty strata.
Results: A total of 22 440 patients comprising 7138 (31.8%) robust, 7913 (35.2%) normal, 5158 (22.9%) frail, and 2231 (9.9%) very frail patients were included. Results from unmatched multivariable analyses revealed a dose-dependent relationship between frailty and all outcomes, in both cohorts ( P < .05). Propensity score-matched resulted in 3942 nonoperative and operative matched pairs. Preoperative characteristics were similar between cohorts, except for age: 75 years (IQR: 60-83) for nonoperative and 70 years (IQR: 56-78) for operative, and male sex: 1799 (55.8%) for nonoperative and 439 (61.1%) for operative cohorts. Significant mortality reductions (43%-77%; P < .05) were observed in the operative cohort compared with the nonoperative cohort across all frailty strata. As expected, the operative cohort had longer LOS and increased NHD risk ranging from 64% to 97%, P < .001. In Kaplan-Meier analyses, survival declined significantly across increasing frailty strata P < .001.
Conclusion: Increasing frailty was independently associated with major complications, LOS, NHD, and decreased survival. Operative patients exhibited improved survival compared with nonoperative patients across all frailty strata. These findings highlight the importance of frailty in T2OF management and care coordination.
