  • Title: Choice of lasers for minimally invasive spinal surgery.
    Author: Stith WJ, Judy MM, Hochschuler SH, Guyer RD.
    Journal: Orthop Rev; 1991 Feb; 20(2):137-42. PubMed ID: 1901165.
    Abstract:
    Recently, there has been increased interest in less invasive spinal surgery techniques. This has led to the development of procedures such as automated percutaneous lumbar discectomy and arthroscopic microdiscectomy. Lasers are now used in many areas of medicine and may have applications in minimally invasive spinal surgery. A number of different laser systems have been evaluated for their effectiveness in removing disc tissue in the laboratory, but technical problems have limited their clinical use. Only the Nd:YAG (1,064 nm and 1,320 nm) and KTP (532 nm) systems have been used clinically. Unsuccessful clinical results were obtained with the 1,064 nm Nd:YAG, whereas the other two systems appeared to produce results similar to the present mechanical systems but required less time for disc removal. This paper discusses considerations for choosing a laser system for spinal applications and reviews the work performed in this area.
