The inner portion of the disc is
soft and spongy and enables it to function as a shock
absorber. Over time the intervertebral discs degenerate,
losing their water content and ability to absorb shock
with movement. Excessive pressure, strain or injury
to a rigid disc can cause the disc to tear and bulge.
This causes the discs to come closer together and
compress the spinal nerve roots, causing pain, numbness
and decreased mobility.
At our partner hospitals the highly
advanced skills of the neurosurgeons include Computer
Assisted Neurosurgery using an operating computer,
which allows them to apply instrumentation within
1 mm of accuracy. Automated percutaneous lumbar discectomy
is done this way. The device they use is also very
advantageous in locating difficult tumors and avoiding
fragile structures during surgery.
Microsurgery (dissection of minute
structures under microscope by hand held instruments)
can be successfully done for lumbar or anterior cervical
discectomy or decompression.
Total disc replacement surgery is
also available when the degeneration of the disc or
discs is so far advanced.
