    Hello,

    The question below is open to anyone viewing this forum…

    Has anyone had an X-STOP procedure in their lumbar spine…and if so what were the results afterwards?

    Thanks Massimo

    You pose a number of question and statements. I’ll do my best to answer.

    X-stops are quick surgical procedures to wedge a metal “blocker” between two spinous processes to force the vertebral segment into kyphosis (flexion). This is performed to “open” the spinal canal (the canal enlarges with flexion). I do not recommend this procedure as this metal device erodes into the spinous processes and the relief is short lasting. It would be better to decompress the canal in the first place than to place a “blocker” between the spinous processes.

    You have Scheuermann’s kyphosis of your thoracic spine. Your overall kyphosis curve is not too abnormal (51 degrees-normal is 20-14 degrees) but these segments can be painful especially at the apex of the curve. For example, if four segments of the thoracic spine (T8-T11) measured 45 degrees and the rest of the entire thoracic spine measured 6 degrees, this focal curve would be significantly pathological. If the curve was not focal but instead distributed throughout the thoracic spine, this would not be too abnormal.

    Just the other day, I fixed a 42 degree kyphosis of T10-T12. The rest of her thoracic spine was actually lordotic (curved backwards-the wrong way) to compensate for that curve. This means the global curve she had prior to surgery was about 39 degrees which was within normal limits but her deformity was very painful.

    Bertolotti’s Syndrome generally does not cause pain as the partial sacralization of the L5 segment is normally stable and not painful. There are some very rare exceptions.

    Baastrup’s Syndrome (kissing spinous processes) is almost never a painful condition. I see it all the time without these articulations causing pain.

    You report “degenerative changes at multi-levels of my Lumbar Spine with mild to moderate foramina stenosis exacerbated by osteophytes, hypertrophic facet disease and ligamentum flavum hypertrophy”. This can cause lower back pain and leg pain, especially with standing and walking.

    Thank you Doctor Gorenman for your insight on the X-STOP Procedure and it’s consequence on the spinous process. Decompressing the canal sounds like a fundamental approach.

    I have researched both Bertelotti and Baastrup Syndromes and I understand that rarely are these problematic. Unfortunately the pain derived from my lumbosacrial/pelvic region and it’s restriction in mobility in fact may be multifactorial.

    During the growth stage of my spine the pseudoarthrosis of the transverse process to the ala of the sacrum caused what seems to be a raised sacrum with it’s enlarged sacral crest.

    The diseased Facet Joints and enlarged spinous process are affected with a moderate degree of Osteochondrosis. Not only are the spinous process touching, however, multiple levels are actually slightly overlapping each other (noted in the 3D CAT SCAN study). More significantly the L5 spinous process and the medial sacrial crest are straddling each other causing the spinous process overtime to actually twist. The anomaly (Bertelotti Syndrome) with Baastrup’s Syndrome have been exasperated in a multi faceted way. Unfortunately the lumbosacrial region appears very crammed and overtime has become more problematic and pain has definitely increased.

    My ignorant perspective with the X-STOP was to create additional space in between the vertebral lumbar levels and canals. In addition alleviating the bone to bone contact of the spinous process.

    Doctor Corenman, will the constant bone to bone contact increase the level of Osteochondrosis and further narrow the canals making my leg issues even worse?

    If a resection of the transitional articulation (transverse process) was performed do you think the drop of the sacrum could create more space for the canals and less bone to bone contact in regards to the spinous process?

    How many vertebral levels were fused in the 42 degree kyphosis that you corrected and what hardware did you use?

    With Thanks,
    Massimo

    Hello Doctor Corenman and Forum Readers

    I have recently researched a surgical institute that performs “GEL FIX IMPLANTS”.
    Has anyone had this procedure performed?

    Thank You

    GelFix implants are yet another iteration of the X-stop. This is an implant device like the Coflex designed to wedge between the spinout processes to distract these structures. This distraction produces flexion of the vertebral segments which is undesirable.

    Hello Doctor Corenman,

    As always, I appreciate your advise. I would like to commend you for your compassion and dedication in part of myself, and your forum readers. You are the modern pioneer to the yesteryear horse and buggy Doctor which devoted his or her life to the principals of medicine.

    Respectfully, I can understand your opinion as to the “Gel Fix Implant”. Upon research, I realize that this device is in fact a parallel to the X-STOP in attribute. As you past mentioned the X-STOP Hardware can be erosive in part to the spinous process. This is how I have come to investigate the “Gel Fix Implant”. This procedure seems more compatible and less destructive to the bone structure of the spine.

    Changing the natural curve and producing “flexion” in the vertebral segments may in fact be undesirable in a somewhat normal spine. The pain I experience in my lumbosacral/pelvic and legs is more than undesirable. It may be due to the fact that this segment is not normal in a multi faceted way. I realize that there is no easy fix to this situation. Creating additional space by raising the spinous process may in fact be like shoring the foundation to a problematic building structure.

    Doctor Corenman, I am a simple person with a great desire to live life with less pain and perhaps to be able to sleep through the night and not be awoken because of pain. In search of this measure I am just trying to make sense from the ground-up “so to speak”. May I inquire…

    (KEEPING IN MIND)
    The posterior lumbosacral segment of my spine are rather crammed in part of the sacrum being raised due to the transverse process being sacralised (Bertelotti’s) along with the enlarged facet joints and spinous process with multi-level degenerative disc changes.

    1) How is the kyphosis of the thoracic spine affected if additional flexion is applied to the lumbar spine …keeping in mind that I do have a Scheuermann’s with a rather more visible curve at the apex of the spine (T7-T9).

    I an just trying to make sense of the fundamental issues throughout my spine. Trying to rewire and replumb a house may not be a starting point in trying to salvage a dilapidating foundation. I see this parallel in my spine. I have great concerns as to the underlying soft tissue degenerative changes throughout my cervical, thoracic and lumbar spine. At times, I wonder if in fact this degenerative reason is due to a structural concern…

    Than You,
    Massimo
