The creation of microcrystals destroy the innervation that transmits pain.
It does not permanently damage the nerves, since they can regenerate.
Cryanalgesia is applied through the nerve that transmits pain. If a pain intensity of Eva is perceived more than 5 is a good indication for the application of cryoanalgesia.
After the application of cryoanalgesia, the axons (which transmit the pain) have been damaged but the layers that surround them (epineuro, endoneuro, perineuro) remain intact. From here at a speed of 1mm / day the axon is regenerated again, but after a few weeks the sensitivity is still altered, and first the motor capacity is recovered. In short, after 6-12 months all sensory and motor capacity has been recovered without pain
Advantages of Cryanalgesia
- There is no risk of secondary pain, there is no risk of neuroma formation.
- High effectiveness duration of analgesia between 6 months and one year.
- Safe in patients with pacemakers.
- Procedure with local anesthesia.
- It can be repeated.

in the geniculate nerve for knee pains
on Morton's neuroma
on the ilioinguinal nerve
