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 Results may not be published yet.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

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

Summary

This study follows 20 people who had surgery as children to correct flatfoot. Researchers want to see if the correction lasts more than 10 years by checking foot structure and pain. They use simple tests like standing on tiptoes and X-rays to measure results.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
calcaneal stop and endorthesis (surgical implants)
What this could lead to
If successful, this could confirm that this surgery provides lasting correction of flatfoot in children, reducing the need for future treatments.
What could go wrong
This is a small, long-term follow-up study with only 20 patients, so results may not apply to everyone. Some patients may have pain or loss of correction over time.

Who is studied

Primary objective: To evaluate, at more than ten years' follow-up, the clinical and radiological outcomes of patients who underwent subtalar arthroereisis with calcaneostop and endorthosis for the correction of pediatric flatfoot. Secondary objectives: To compare, within the same patient, the clinical and radiological outcomes of feet treated with subtalar arthroereisis using calcaneostop versus endorthosis.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

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

INCLUSION CRITERIA: Patients already in follow-up after undergoing subtalar arthroereisis with calcaneostop and endorthosis, enrolled in the study "Flatfoot treatment: comparison between resorbable endorthosis and resorbable calcaneal stop" by Prof. Giannini, still in follow-up at IOR. EXCLUSION CRITERIA: Patients who have undergone subsequent surgical procedures on the foot and ankle
