Back Pain, Low, Degenerative Disc Disease
Conditions
Brief summary
The aim of the present study is to find out whether fusion of a sinlge level SPECT/CT positive degenerative disc disease leads to a significant improvement of pain and disability.
Detailed description
Chronic back pain (CBP) is a very common clinical problem. It is dominantly caused by degenerative changes, while specific causes such as tumor, trauma or inflammatory conditions are relatively rare. Back pain may be a concomitant symptom of lumbar disc herniation or spinal canal stenosis and is a typical symptom of spondylolisthesis. Magnetic resonance imaging (MRI) plays a key role in the diagnosis, showing in detail the soft structures, vertebral bodies (Modic changes, MC) or signs of facet arthropathy. On the other hand, it also proves a number of clinically silent findings. Degenerative disc disease (DDD) or facet osteoarthritis are most often considered to be a pain generator. The problem, however, is that both entities are very common in the general population without a painful correlate, and there is still controversy in the literature about their role in the genesis of CBP. Radionuclide bone scintigraphy with single photon emission computed tomography (SPECT) provides functional imaging and is used to detect microcalcification due to increased osteoblastic activity. In the absence of other pathology the foci of increased osteoblastic activity reflex areas of mechanical stress and degenerative change in the skeleton. There is growing evidence about the relationship between DDD, facet arthropathy, and SPECT positivity. Although these findings have been recently confirmed by surgical studies, the evidence about the effect of surgical treatment of SPECT positive lumbar degeneration is still weak due to the small number of operated patients. The aim of the present study is to define a possible correlation between degenerative changes of the lumbar spine and positivity on SPECT/CT imaging. Patients with a single level SPECT+ DDD will undergo spinal fusion of the involved segment. Postoperative improvement will be measured by ODI (Oswestry Disability Index) and pain VAS (Visual Analogue Scale) in 6 and 24 months follow-up period.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Improvement in Oswestry Disability Index (ODI) | 2 years | The Oswestry Disability Index (ODI) is an index derived from the Oswestry Low Back Pain Questionnaire. The self-completed questionnaire contains ten topics concerning intensity of pain, lifting, ability to care for oneself, ability to walk, ability to sit, sexual function, ability to stand, social life, sleep quality, and ability to travel. he scores for all questions answered are summed, then multiplied by two to obtain the index (range 0 to 10). Zero is equated with no disability and 10 is the maximum disability possible. |
| Improvement in Pain Visual Analogue Scale (VAS) | 2 years | The visual analog scale (VAS) is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between VAS 0 (no pain) and VAS 10 (worst pain). |
