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 Results may not be published yet.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 will use tiny probes called microdialysis to measure chemicals related to blood flow, inflammation, and antibiotics right inside the amputation stump after surgery. Researchers will compare results between diabetic and non-diabetic patients to understand why some stumps heal poorly. The goal is to gather knowledge that could improve wound care after leg amputation.

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 improve understanding of wound healing after amputation, potentially leading to better post-surgery care.
What could go wrong
This is a small, early observational study with only 20 participants. It is not testing a treatment, so direct patient benefits are not guaranteed.

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

Expected to finish

Jan 2028

An estimate. End dates often move.
