Ormiston Hospital Spinal Surgery
Private Surgical Service, Spinal
Laminectomy or Laminotomy
These procedures involve making an incision down the centre of the back and removing some or all of the bony arch (lamina) of a vertebra.
In a laminectomy, all or most of the lamina is surgically removed while a laminotomy involves partial removal of the lamina.
By making more room in the spinal canal, these procedures reduce pressure on the spinal nerves. They also give the surgeon better access to the disc and other parts of the spine if further procedures e.g. discectomy, spinal fusion, are required.
