Is this trial a fit for you?

Likely a good fit

Adults (age 18 or older) who have had or will have an upper or lower limb amputation and are able and willing to give informed consent are ideal candidates.

Probably not a fit

Patients under 18, women who are pregnant or planning pregnancy, or those unable to consent or adhere to follow-up may not benefit or be eligible for inclusion.

What this trial studies

This is an observational registry that collects real-world data on the use of cryoablation (freezing nerves) during upper and lower limb amputations at several hospitals. Investigators will record procedural details, pain measurements, complications, and follow-up outcomes related to post-operative and phantom limb pain. Eligible adults who have or will have an amputation and can provide consent will be enrolled and followed according to the registry protocol. Women who are pregnant or any patient unable to give informed consent or adhere to follow-up are excluded.

Why it matters

Potential benefit: If successful, the registry could help clinicians understand whether nerve-freezing during amputation reduces post-operative and phantom limb pain and inform future care decisions.

How similar studies have gone: Smaller case series and observational reports have suggested cryoablation can reduce neuroma-related and phantom limb pain in some patients, but randomized high-quality evidence is limited.
