DESTANDAU Endoscopic Approach with the Mobile
ENDOSPINE® Operating Tube
For central to far lateral disc herniations and lumbar spinal stenosis
Lumbar disc herniations and lumbar canal stenosis occur very frequently. If surgery is required,
the standard surgical treatment remains a posterior approach to the spine. The ENDOSPINE®
operating tube makes treatment of all kinds of disc herniations from medial to far lateral
possible, not only on the lumbar spine but also for the cervical and thoracic levels. Lumbar
canal decompression is also possible.
Especially when operating on adipose patients or in very deep-seated pathologies like a
foraminal disc hernia or spinal canal stenosis, using the ENDOSPINE® operating tube allows a
smaller skin incision while retaining a standard surgical approach. The difference is, however,
that the surgeon has a view right inside the surgical field, very close to the pathology being
treated.
Apart from the aesthetic aspect, the more atraumatic approach with the ENDOSPINE®
operating tube provides a better post-operative comfort, a faster recovery and a faster return to
normal activities.

l 4 degrees of freedom

l Unsurpassed view of the anatomy
l Minimized bone resection
Treatment of medial disc herniations
After a paramedian incision, the
ENDOSPINE® operating tube is inserted in
the direction of the posterior arc.
Bone resection includes part of the
superior lamina and of the intervertebral
articulation with exposure of the dural sac
and nerve root.
The posterior longitudinal ligament needs to
be resected as well. Once the nerve root has
been identified, it is generally retracted using
the integrated nerve retractor.
The herniated portion of the disc is expelled
by pressure from the spatula and extracted
using the grasping forceps.

Treatment of foraminal and extra-foraminal herniations
The paramedian incision is made 1 cm
more cranial than in the case of a medial
herniation. The operating tube faces the
foramen at the level of the exiting nerve
root, slightly above the disc space.
The lateral limit of the isthmus is exposed.
The nerve retractor, which is not utilized
as such in this kind of procedure, can be
used as a muscle retractor. To achieve this,
the nerve retractor is inserted upside-down
outside the operating tube to retract the
paraspinal muscle laterally.
After bone resection with the KERRISON
punch, the ligament is exposed and
removed. Dissection around the nerve root
leads to herniation.
After removal of the herniation with a
grasping forceps, the nerve root is freed.

Treatment of lumbar spinal stenosis
Spinal stenosis is responsible for intermittent radicular claudication and is probably the
leading cause of impaired mobility in elderly people.
If the diagnosis is made before the onset of neurological signs, decompression surgery
enables the patient to quickly regain their usual autonomy.
The aim of this endoscopic technique is to minimize surgical trauma and to offer surgical
treatment to elderly patients whose loss of mobility could lead to severe complications.
The goal of the mobile ENDOSPINE® system is bilateral decompression using a unilateral
posterior endoscopic approach. This operation can be performed under spinal anesthesia or
under general anesthesia. The aim of this surgical technique is bilateral decompression using
an unilateral approach.
The approach is basically the same as for medial disc herniations and is preferably started
on the left side. Part of the superior lamina and the medial part of the intervertebral
articulation are resected to expose the thecal sac.
The lateral expansion of the yellow ligament and a part of the intervertebral articulation have
to be removed, working in a caudal direction, to decompress the left side of the spinal canal
and the left nerve root.
The ENDOSPINE® is then tilted to the other side and the same procedure is repeated on
the right side, i.e. to decompress the right side of the spinal canal and the right nerve root.
Cotton swabs are used during the procedure to protect the dural sac.
For a single level stenosis, the operating time is less than one hour and the hospitalization
period is 48 hours. Special postoperative precautions are not necessary and the patient can
immediately return to normal walking activities.
The advantage of this technique lies in its minimal invasiveness. Furthermore, immobilization
or fixation with plates, screws or cages is not required. The resulting reduction in costs is an
advantage in both the so-called developed countries where health costs are exponentially
increasing as well as in other cost-sensitive countries.
