Microscopic decompression

...without FUSION

Often the desired enlargement of the spinal canal and decompression of the pinched nerves is possible only with a surgical removal of protruding osteophytes. This used to be a complex surgery on the open spinal canal in the past where great parts of the vertebral arches and joints were removed (laminectomy). Modern minimally invasive techniques today allow for a very tissue-preserving intervention as nerves and blood vessels running through the spinal canal remain unhurt. With the aid of a surgical microscope greatly enlarging the operating field a removal of the narrowing structures to the nearest millimeter is feasible. The natural physiological and biomechanical conditions are kept and the stability of the spine is maintained. Surgery and recovery times are much shorter than with conventional stenosis surgery. The obtained results are better than with traditional techniques like laminectomy where the vertebral arches are almost completely removed.

In rare cases a spinal stenosis comes along with so called degenerative slipped vertebrae. If during surgery a relative instability is detected, additionally to the microscopic decompression a fixation is carried out. A filament (a thick thread) is pulled around the spinous processes in the shape of an eight as a stablizing cerclage. 

Modern technique allows for even more tissue-preserving surgery

The tube-technique is a new microscopic decompression technique. Widening of the spinal canal is done with the aid of a so-called trocar. This small tube is inserted dorsally via a small skin incision and under microscopic sight-control carefully pushed forward to the narrowed section of the spinal canal. The advantage with this small tube – the trocar – is that muscles do not have to be removed from the bone. All narrowing structures are thoroughly removed with minute surgical instruments that can be pushed forward through the trocar so that in the end the nerves are freed. 

 The intervention is done under general anesthesia and takes about 45 minutes.

The next day and then again after three months there will be follow-up examinations. 

What postoperative care is necessary?

During the first two weeks you will have to put on a specially fitted plastic corset that sustains your back and will soon allow for resuming daily activities. It is recommended to start a professionally supervised physiotherapy two weeks after the intervention.  

When may I resume my sports activities?

After about six weeks you should be able to go swimming or to ride your bicycle. Your may resume your usual sports activities after 9 weeks.

When can I go back to work?

After two weeks you can resume simple office work and slight physical work. You shouldn’t do any hard physical work during the first three months and then only gradually increase.

What is the success rate?

In the international scientific literature success rates of about 85% are quoted.

The most important facts at a glance for your convenience
  conventional stenosis surgery MIOR©- minimally invasive surgery and reconstruction of the spinal canal
  • Surgery visualized only with the naked eye is less precise
  • healthy bone material must be removed to access the spinal canal
  • often instability of the spine develops
  • frequent damage of the dura
  • spine stability is preserved
  • With the help of the microscope bone spurs can be removed very precisely
  • the spinal canal is meticulously reconstructed
  • Healthy bone structures are preserved and remain stable
  • Pain often prevail or new symptoms develop after surgery
  • pain usually subsides within a couple of days after surgery
  • How long it takes for all symptoms to disappear depends on severity of stenosis
After the intervention
  • As a rule return to activity takes 6 weeks.
  • You can go back to some activity already 3 hours after surgery with a specially tailored brace.
Hospital stay
  • 1-3 weeks
  • 2-4 days
  • Rapid and extensive removal of bone substance
  • often the vertebrae are fixed with metal rods
  • Not all bony spurs (stenosis) can be recognized and removed, if the surgeon works without a microscope
  • As small natural openings of the spinal canal are used for the intervention, surrounding structures are preserved
  • A fixation with metal rods is not necessary
  • Natural stability of the spine is preserved
  • As a microscope is used, all bony spurs (stenosis) can be recognized and removed
  • Resuming sports activity is virtually impossible
  • After rehabilitation usual physical activity is possible
  • Long waiting times are not unusual.
  • In acute cases you can be operated on within 48 hours.


 !!! Flexibility and function of the spine are fully preserved !!!

All advantages at a glance:
  •  Short surgery time
  •  A smaller incision and a tissue-preserving procedure where muscles and nerves remain unhurt. This leads to a less cumbersome intervention with a low complication risk
  •  Stability of the spinal column is preserved
  •  Already two hours after the intervention you will be able to stand or walk without pain.
  •  No long hospital stay is necessary: two to three days after the intervention your may go back home again
  •  Short recovery time: Already three weeks after the intervention you may resume your usual activities
  •  Almost no scarring
  •  High success rate


I needed to tell just one sentence and diagnosis was established and then also confirmed by imaging techniques. Neither the orthopedic specialist nor the radiologist I had visited before, had identified the herniated disc. They told me to do some sports and that surgery would not help. Immediately after the surgery in the ATOS clinic, my symptoms disappeared and I was also pain free. Absolute number 1 address for spinal disc problems.
