All-cause mortality risk in older patients with femoral neck fracture
Abstract
INTRODUCTION: The mortality rate after hip fracture is high. However, the 1-year mortality rate after femoral intertrochanteric fracture and femoral neck fracture differs (Gibson-Smith D, Klop C, Elders PJ, Welsing PM, van Schoor N, Leufkens HG, et al., Osteoporos Int 25:2555-2563, 2014), although both are types of hip fracture. A previous real-world single-center prospective cohort study showed that older age and high Charlson comorbidity index score were risk factors for femoral intertrochanteric fracture. Additionally, therapy with zoledronic acid 5 mg (Aclasta) was a protective factor (Li XP, Zhang P, Zhu SW, Yang MH, Wu XB, Jiang XY, J Orthop Surg Res. 16:727, 2021). We wished to determine the risk factors for all-cause mortality in femoral neck fracture patients.
AIM: To identify the risk factors for postoperative all-cause mortality in aged patients with femoral neck fracture.
MATERIALS AND METHODS: We enrolled 307 aged patients with femoral neck fracture; 38 were lost to follow-up after 2-3 years. The patients' general characteristics, bone mineral density, and anti-osteoporosis treatment after operation were recorded as potential risk factors. Kaplan-Meier curves and multivariate Cox proportional hazards models were constructed to analyze the influence of each factor on all-cause mortality.
RESULTS: This was a real-world single-center prospective cohort study showing that (1) most of the patients who died were male, older (mean age of the patients who died: 84.8…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 307 participants or records.
