Hi all,
I have some informative links about the decompressive techniques
used in posterior approach surgery. First is laminectomy :
http://spinecarehk.com/index_files/CTNavigation.htm. There are some
photos in surgery- may be too graphic for some, but very informative.
Also shows how the surgeons use CT for navigation in surgery.
For laminoplasty : http://spinecarehk.com/index_files/Laminoplasty.htm
, shows how the surgeon makes a trap door to expand the space in the
spinal canal.
Hope this helps answer some questions.
George
