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 This study
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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study examines 20 adult cadaveric lower limbs to map where motor branches of the tibial and peroneal nerves enter their target muscles. Researchers measure each entry point relative to leg length and calculate probability intervals. The goal is to provide quantitative anatomical references that could support surgical planning for procedures like hyperselective neurectomy.

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 anatomical mapping could give surgeons a clearer reference for planning lower-leg procedures, potentially improving precision and outcomes.
What could go wrong
This is a small cadaveric study, not a clinical trial in living patients. Results may not fully translate to surgical practice, and the sample size limits generalizability.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Fresh-frozen adult cadaveric lower-limb specimens available through the institutional cadaveric program at CLEMI in Cundinamarca, Colombia. Specimens were selected according to institutional procurement standards and were required to have no prior trauma or surgical intervention involving the lower limbs. One extremity per cadaver was selected by coin toss for dissection.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: * Adult cadaveric specimen (age at death 18 years or older) * Fresh-frozen lower-limb specimen made available under institutional standards for cadaveric research * No prior trauma involving the selected lower limb * No prior surgical intervention involving the selected lower limb Exclusion Criteria: * Cadaveric specimen from an individual younger than 18 years at death * Prior trauma involving the lower limb * Prior surgical intervention involving the lower limb
