What this trial studies

This trial evaluates the effects of a 4-week postoperative essential amino acid (EAA) supplementation on muscle health following femoral fragility fractures. Participants will be randomly assigned to receive either standard care or EAA-based supplementation, with assessments conducted over a 6-month period. The study aims to measure changes in muscle morphology, metabolic activity, inflammation, and physical performance, utilizing muscle biopsies and body composition analysis. The goal is to determine if EAA supplementation can enhance recovery and preserve muscle mass after surgery.

Who should consider this trial

Good fit: Ideal candidates are hospital inpatients aged 65 and older who have sustained a low-energy femoral fracture and are indicated for surgical fixation.

Not a fit: Patients who are non-ambulatory prior to injury or have cognitive impairments may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve recovery outcomes and muscle health for patients recovering from femoral fractures.

How similar studies have performed: While the specific approach of EAA supplementation post-fracture is novel, similar studies have shown positive outcomes in muscle recovery and health in other contexts.
