What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
Running, but no longer taking on new participants.
Completed
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 Results may not be published yet.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
Cancelled before anyone took part.

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 at Montpellier University Hospital will look at whether low muscle mass and strength before hip replacement surgery affects how well people aged 75 and older regain their independence. About 20 volunteers will have blood tests, scans, and a tiny muscle sample taken during their surgery. Researchers will then check on their recovery at 3 and 6 months to see if muscle weakness predicts slower healing.

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 could help doctors predict recovery after hip surgery and design better exercise and nutrition plans for older adults.
What could go wrong
This is a very small, early exploratory study with only 20 participants. It is not testing a treatment, so it may not lead to direct changes in care.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Participants

About 20 people

The number the study aims to enrol. It can still change while the study runs.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: \- Elderly subjects undergoing surgical hip replacement for fracture of the upper end of the femur or severe hip osteoarthritis. Exclusion Criteria for both groups : * Contraindications to MRI : pacemaker, metallic implants. * Presence of a lower-limb prosthesis on the contralateral side to the surgery that may interfere with quadriceps mass measurements. * Progressive high-grade neoplasia. * Documented major cognitive disorders * Under legal protection measures (guardianship, conservatorship, or curatorship). * Subjects not affiliated with or not covered by a social security system. * Participation in another ongoing study with an active exclusion period. Exclusion criteria - Fracture group : * Fracture with a suspicion of underlying neoplasia. * Placement of a lower-limb prosthesis on the surgical side within the last 12 months. * Inability to walk with or without human/technical assistance prior to fracture. Exclusion criteria - Hip osteoarthritis group : \- Active inflammatory joint disease (rheumatoid arthritis, spondyloarthritis).
