It is a therapeutic method that bases its effect on the temporary interruption of peripheral nerve sensory conduction through the application of a low temperature.

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.

on the occipital nerve

suprascapular nerve for shoulder pain

in the geniculate nerve for knee pains

on Morton's neuroma

on the ilioinguinal nerve

Clinical applications of Cryanalgesia

  • Acute postoperative thoracotomy pain
  • Syndromes of facial pain (supra infra orbital, occipital, mental)
  • Suprascapular, ilio-inguinal and other specific neuralgia.
  • Low back pain and lower limb pain secondary to lumbar, pseudosciatic facet pathology.

  • Facet syndrome – cervical, thoracic and lumbosacral
  • Coccydynia Perineal neuropathies Phantom member
  • Activation points
  • Painful neuromas


  • Anterior or secondary knee pain to the infrapatellar branch of the saphenous nerve, cutaneous anterior femoral nerve, genicular nerve after total knee arthroplasty.

  • Tennis elbow syndrome and golfer’s elbow syndrome
