What makes muscles weak in frail seniors after a hip break?
NCT ID NCT04764617
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 80 frail older adults who had hip surgery after a fall. Researchers took small muscle samples to measure fat, protein, and gene activity. The goal was to understand whether muscle amount or muscle function matters more for recovery. This is a knowledge-gathering study, not a treatment test.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could help identify why some frail older patients recover poorly after hip surgery, pointing toward ways to improve muscle health and recovery.
- What could go wrong
- This is an observational study, not a treatment trial. It aims to gather knowledge, not test a therapy, so it won't directly change patient care.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Clinical Frailty Score (assessed as part of standard care) ≥ 4 * Fractured hip, sustained following a fall, that requires surgery * Good understanding of spoken and written English language * Able to give informed consent, or availability of a legally acceptable surrogate to provide consent Exclusion Criteria: * Those who fell and sustained their hip fracture greater than 12 hours prior to hospitalisation. * Those who have fallen and sustained a hip fracture whilst an in-patient in hospital * Those who sustained the hip fracture as a result of high impact trauma (e.g. road traffic accident) * Surgery carried out later than 96 hrs after fall * Chronic neurological, inflammatory or musculoskeletal disorders which result in muscle wasting, e.g. Multiple sclerosis, muscular dystrophy, rheumatoid arthritis * Any co-morbidity which precludes hip surgery * Those with a compromised swallowing reflex which would prevent the participant from taking fluids orally, will be excluded. * Those taking diabetes medication
