Preoperative Oral Nutrition And Outcomes In Frail Elderly Patients With Femur Fractures

The goal of this observational study is to learn whether preoperative oral nutrition support improves clinical outcomes in elderly patients with femur fractures who have a high frailty index. The main questions it aims to answer are: * Does preoperative nutrition support improve hemodynamic stability during and after surgery? * Does it reduce postoperative complications, mortality, and length of hospital stay? Researchers will compare patients who receive preoperative oral nutrition support with those who follow routine nutrition. Participants will: * Receive routine medical care with or without nutrition support * Have their hemodynamic values, complications, and outcomes recorded during hospitalization * Be followed at 30 and 90 days after surgery for complications and mortality.

Inclusion Criteria: * Patients aged 65 years or older hospitalized with a diagnosis of femur fracture * High frailty index (Clinical Frailty Scale ≥ 5) * Patients expected to require postoperative intensive care Exclusion Criteria: * Patients requiring preoperative intensive care * Patients unable to tolerate enteral nutrition * Patients with advanced liver or kidney failure * Patients unable to cooperate * Patients with neuromuscular disease * Patients with severe malnutrition according to NRS-2002 guidelines * Patients who refuse to participate
