Lumbar Disc Surgery
We practice lumbar disc surgery in some indications, on an out-patient basis. This is rendered possible by the association of Minimally-Invasive Surgery (minimal access spine technologies, MAST) and Microsurgery (use of microscope and micro-instruments).

Microsurgery has revolutionized spine surgery. The microscope permits visualization of the nerve roots and the disc fragments, much better than with loops or the naked eye. Our last generation Zeiss microscopes are used on a daily basis to treat lumbar discs. Combined with the use of micro-instruments, security of the surgery is highly increased, and the rate of complications is maximally decreased.

With over one thousand five hundred lumbar disc surgeries in the last five years, we offer our patients the maximum chances of recovery. 

Video below: the Metr'x (Medtronic) tubular retractor system mini-invasive technique for the removal of lumbar disc hernias. Our patients appreciate going back home the same day, with little or no pain. They resume their normal life activities soon after the surgery.

Potential benefits of the mini-invasive techniques include:

  • Shorter hospital stays – outpatient surgery
  • Smaller scars – one inch vs. up to four inches
  • Quicker return to work and normal activities
  • Less post-operative pain – no muscle cutting or stripping

Left image: herniated disc impinges on exiting nerve root, causing sciatica or lower leg pain. After excision of the hernia, the nerve root is no more compressed.
Right image: Metr'x (microscopic endoscopic tubular retractor system, Medtronic, USA) permits, through an 18 millimeters incision, and successive dilatation of muscle fibers, to place a tubular retractor which permits to get access to the hernia. Dissection and excision of the hernia is done using the microscope and micro-instruments.

Multi-level Percutaneous Pedicle Screw/Rod Fixation
The CD Horizon Longitude (Medtronic) system allows percutaneous placement of pedicle screws and rods through 18 mm incisions.This minimally invasive technique permits stabilization of unstable fractures without the need of big incisions and muscle dissection, therefore minimizing blood loss and post-operative pain. It benefits mainly to older people, without severe osteoporosis (absolute contra-indication).
