Pulmonary Embolism Post-Femoral Neck Fracture Surgery: A Critical Predictor of Five-Year Mortality.

Objectives: This study examines the impact of pulmonary embolism (PE) on mortality among patients with femoral neck fractures, exploring the predictive value of preoperative PE for postoperative occurrences and associated mortality over a 5-year follow-up period. Methods: We analyzed 2256 patients over 60 years old admitted with femoral neck fractures, focusing on those who developed DVT or PE postoperatively. Surgical intervention aimed within 48 hours without pharmacological thromboprophylaxis, utilizing mechanical prophylaxis instead. Postoperative management included Enoxaparin administration. Data analysis employed SPSS 21, with chi-squared tests, T-tests, and multivariate logistic regression to explore mortality and PE incidence. Results: PE was diagnosed in 1.4% of patients, with a notable mortality contrast between patients with PE (87%) and those without (59.7%) over 5 years. A history of preoperative PE emerged as a significant risk factor for postoperative PE. Despite surgical variations, no significant correlation was found between surgery type and PE incidence. Early postoperative weight-bearing and institutional rehabilitation did not significantly alter PE incidence rates. Conclusions: The study underscores the significant mortality risk associated with preoperative PE in femoral neck fracture patients. It highlights the necessity for vigilant PE risk assessment and management, challenging assumptions about the protective role of early mobility and rehabilitation in PE incidence. Further research is essential to refine patient care strategies and improve outcomes.
