An interventional study of Neodymium magnet-guided foreign body removal in Foreign Bodies, Soft Tissue Foreign Body and Wounds, Penetrating, sponsored by Uludag University. Recruiting at 1 site in Turkey (Türkiye). Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-11-09.
Sponsored by Uludag University · Not applicable, Interventional, and Treatment
The goal of this clinical trial is to learn if a strong magnet (neodymium magnet) can help doctors remove metal objects stuck under the skin in adults. It will also learn about the safety of this method. The main questions it aims to answer are:
Participants will:
This prospective, single-center, single-arm study is conducted in the Emergency Department of Bursa Uludag University Faculty of Medicine Hospital. Before the procedure, the location of the foreign body and its distance from the skin surface are measured on X-ray, and the entry site is photographed. Before sterile preparation, the magnetic property of the foreign body is confirmed with the neodymium magnet. After sterile preparation, the foreign body is localized with a sterile-draped neodymium magnet. Local anesthesia is applied if needed. The foreign body is removed through the existing wound or, if there is none, through a skin incision. The site is photographed again after removal. Prophylactic antibiotics are given for contaminated wounds. Participants are re-evaluated at suture removal or 15 days after the procedure.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Adults with a magnetic metallic foreign body in the soft tissue. The foreign body is removed with the help of a neodymium magnet in the emergency department, with or without local anesthesia.
Procedure: Neodymium magnet-guided foreign body removal
After sterile preparation, the foreign body is localized and pulled toward the skin surface with a sterile-draped neodymium (NdFeB) magnet, and removed through the existing wound or a skin incision.
Also known as: Rare earth magnet
Successful removal of the foreign body
Number and percentage of foreign bodies successfully removed with the help of the neodymium magnet.
Time frame: During the procedure (Day 0)
Complete removal per participant
Number and percentage of participants in whom all foreign bodies were successfully removed.
Time frame: During the procedure (Day 0)
Procedure time
Duration of the foreign body removal procedure, in minutes.
Time frame: During the procedure (Day 0)
Need for additional incision and its length
Number and percentage of participants who need a new or additional skin incision, and the length of the incision in millimeters, if required.
Time frame: During the procedure (Day 0)
Volume of local anesthetic
Volume of local anesthetic used during the procedure, in milliliters, in participants who receive local anesthesia.
Time frame: During the procedure (Day 0)
Complications
Number and percentage of participants with complications (such as wound infection or bleeding) within 15 days after the procedure.
Time frame: 15 days after the procedure
Patient satisfaction
Participant satisfaction with the procedure on a 5-point Likert scale (1 = not satisfied at all, 5 = very satisfied). Higher scores mean greater satisfaction.
Time frame: Immediately after the procedure (Day 0)
Plan to share: No — Individual participant data will not be shared because the informed consent form and ethics approval do not cover sharing of individual-level data with third parties. Aggregated results will be published.
