Cryo nerve block for pain after amputation
Part of Injuries & trauma, Pain clinical trials.
This study is testing a treatment called a cryo nerve block to reduce pain after amputation, including phantom limb pain. It will look at whether freezing the nerve during surgery helps people feel less pain and use less pain medicine.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have already had an amputation or you are scheduled to have one.
- You are able to understand the study and give your written okay (informed consent).
- You are at least 18 years old (or the legal age in your state).
- If you are a woman who could become pregnant, you are not pregnant and do not plan to become pregnant during the study.
- You do not have any other medical, social, or mental health condition that would make it unsafe or impossible to follow the study rules.

This study looks at whether a temporary numbing injection (nerve block) can predict how well a longer-lasting freezing treatment (cryoneurolysis) will relieve chronic pain or muscle tightness. If you're eligible, you'll get the freezing treatment, which may provide longer-term relief.
This study compares two ways to manage pain after a below-knee amputation: one uses a standard numbing medicine (local anesthetic block), and the other adds a mild electrical stimulation to the nerve to see if it provides better pain relief. If you qualify, you may get extra help with pain after surgery.
This trial tests a freezing technique to numb nerves around the lungs during minimally invasive lung surgery. It may help reduce pain after surgery, so you need less pain medication.
This study tests two surgical techniques—target muscle re-innervation and regenerative peripheral nerve interfaces—alone or together, to help reduce pain felt in the remaining limb or the missing limb (phantom pain) after amputation for cancer. The goal is to find the best way to manage pain and improve quality of life.
This study tests a new type of nerve stimulation device placed in the leg to see if it can reduce long-term pain after amputation. It's for people who have already had nerve surgery and still have significant pain.
This study watches how well a freezing procedure works for chronic pain over 6 to 12 months. Your doctor thinks this procedure could help your pain, and the study simply tracks your recovery through questionnaires to help doctors understand if it works.
