Artificial Disc compared to the spinal fusion patients. It must be noted that disc arthroplasty is only appropriate for very specific indications and it does not replace the need for lumbar spinal fusion in every case.
Total disc arthroplasty represents only one option among motion preservation technologies available to spine surgeons today. The dimensions of the spinal canal and lateral neural foramen change significantly with
posture. In a degenerated spinal segment, extension can cause anatomic structures to compress the spinal cord and/or nerves, leading to various symptoms including neurogenic intermittent claudication. These patients complain of low back and buttock pain that radiates down the legs. Most notably, their pain is worse with prolonged standing and walking and relieved by sitting or bending forward. The X STOPPK™ ("eXtension STOP") significantly prevents narrowing of the spinal canal and neural foramina in extension, decompressing the individual degenerative spinal level(s) that provokes symptoms.
X STOPPK™-Interspinous Process Decompression (IPD®) System is designed to relieve the patient's symptoms while standing and walking, which allows the patient to resume their normal posture.
X STOPPK™ represents a significant breakthrough in lumbar spinal decompressive surgery. Placed between the spinous processes of the symptomatic disc levels, it reduces loading on the disc, annulus and facets, and increases the area of the spinal canal and foramen, relieving patients' symptoms. After Interspinous Process Decompression, patients are able to stand and walk without flexing their spines to get relief of pain.
The X STOPPK™ is minimally invasive and requires no removal of bone. It has a low complication rate and can be implanted under local anesthesia in an out-patient setting. Compared to the more traditional laminectomy, with or without fusion, the procedure is shorter and recovery and rehabilitation is faster. Most importantly, The X STOPPK™ represents a non-fusion technology that is non-destructive and reversible.
This represents a sampling of the new trends in the surgical management of degenerative disease of the lumbar spine. There are many other technologies currently being developed, including a variety of other posterior motion preservation technologies and disc nucleus replacements.
