What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing

Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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
