  • The introduction of cryoanalgesia has reawakened interest in the therapeutic use of cold as a means of producingpain relief: The historical background to both local cooling and nervefreezing is recorded and the advances since the introduction of cryoprobes in 1961 are described
  • The introduction of percutaneous freezing was made possible by the development of the enclosed gas expansion cryoprobe by Amoils.l7 The principle involved is the Joule Thompson or Kelvin effect whereby gas under pressure escaping through a small orifice expands and cools
  • Unlike the peripheral use of both phenol and alcohol it has no tendency to cause neuritis, and should pain return when sensation returns the technique can be safely repeated without any ill effects
