Hip Fracture Leads to Transitory Immune Imprint in Older Patients.

Hip fracture (HF) is common in the geriatric population and is associated with a poor vital and functional prognosis which could be impacted by immunological changes. The objective here is to decipher immune changes occurring in the 1st days following HF and determine how phenotype, function, and regulation of innate and adaptive compartments adapt during acute stress event. We included HF patients, aged over 75 years.
