Neurophysiologic studies can be helpful to fur- ther confirm the diagnosis and allow for a differential diagnosis.. 4 ) often associated with spinal stenosis are:. congenitally narrow spinal canal. Degenerative spondylolisthesis is indicative of a spinal stenosis. Degenerative spondylolisthesis particularly at the L4/5 level in females is fre- quently associated with spinal stenosis ( Fig.

Lumbar Spinal Stenosis. Lumbar spinal stenosis can be defined as any narrowing of the spinal canal, lateral recess or intervertebral foramen. Spinal stenosis most frequently results from degenerative alterations of the motion seg- ment. Lumbar spinal stenosis is a common condition in elderly patients. Spinal stenosis is often associated with degen- erative spondylolisthesis. The cardinal symptom of spinal stenosis is neurogenic claudication.

The blockade level increases after epi- dural anesthesia and spinal anesthesia [12, 13]. 30% reduction in the DSCSA and sagittal an- teroposterior diameter has been observed in patients with lumbar spinal stenosis [15. The DSCSA is a more sensitive measurement parameter to predict lumbar cen- tral canal spinal stenosis [16. Thus, measuring the sagit- tal anteroposterior diameter of the dural sac with ultrasound can evaluate the degree of lumbar central canal spinal stenosis..

Portal made the first description of spinal stenosis in 1803. The first evidence of spinal stenosis can be found in Egyptian mummies. The first report of a spinal stenosis is attributed to the French surgeon Antoine Portal in 1803. He observed at autopsy three specimens with narrowing of the spinal canal [93]. He was also able to relate the pathological findings to the typical clinical symptoms of spinal stenosis.. Vittorio Putti was the first to report the relevance of foraminal stenosis.

For example, deformity may be interpreted on one of the MRI cuts as spinal stenosis since the whole deformity is not in the same plane;. however, the patient has no signs of spinal stenosis at all.. Primary and secondary degenerative scoliosis. a, b Secondary degenerative scoliosis on the basis of an idiopathic scoliosis is usually more strongly expressed, c, d less osteoporotic and longer than a primary degenerative scoliosis .

Spinal injection studies have been advocated to differentiate a symptomatic from an asymptomatic lesion because of the low positive predictive value of imaging studies . The second rationale is to use spinal injections to support non-operative treatment in patients suffering from nerve root compromise, spinal stenosis, or facet joint osteoarthritis. Lumbar and Cervical Nerve Root Blocks.

Secondary pathologies include sclerosis and bone formation of the endplate, re- stricted blood supply to the disc and formation of osteophytes, ending up in spinal deformities. These changes can, together with changes in the posteri- or joints and spinal ligaments, cause spinal stenosis.. The ligaments of the spine provide in- trinsic stability and limit motion in all planes.

The radiographs showed decompensation of the adjacent levels with significant retroposition of the vertebral body C3 producing severe spinal stenosis (d, e).. A one-stage surgery was performed with initial anterior resection of the vertebral body of C3. With this step, decompres- sion of the spinal canal and reduction of the deformity was achieved. In the same sitting, posterior fixation was carried out to maintain reduction and stability.

Degenerative disorders, particularly spinal stenosis and disc herniation, most frequently occur in the cervical and lumbar spinal seg- ments due to the biomechanical spine properties (anatomical characteristics) and dynamic/static forces acting on these segments. spinal cord injury, SCI) are mainly caused [30] by:.

Non-rigid posterior stabilization of the spine is another concept for the treat- ment of various spinal pathologies. The aim is to improve functional spinal stenosis by indirect widening of the spinal canal.. removal of the facet joint with Graf ligamentoplasty, flexibility is significantly reduced in all directions compared to the intact state [94].

Hence, for decompression surgery for a herni- ated disc or spinal stenosis, the most important outcome may be the reduction of leg pain or sensory disturbances and/or walking capacity, whereas for “chronic degenerative low back pain”, the relief of low back pain will primarily govern the degree of success.

However, a suture of the dura is very dif- ficult and can cause stenosis. A further cause may be venous congestion in the presence of preexisting lumbar spinal ste- nosis [52]. The risk of unintended durotomy and cerebrospinal fluid (CSF) leaks can be reduced with increasing surgical experience. Dural tears should be repaired (if possible). In severe spinal stenosis, which often presents with adhesions, dural tears occur even in the hands of experienced surgeons.

From the spine surgeon’s perspective, the assessment of an osteoporotic fracture includes consideration of the following criteria ( Fig. vertebral fractures with subsequent spinal stenosis/neural compression. Typical morphometric criteria for diagnosing incident fractures: Melton [68] defines a vertebral fracture as present if any of the ratios AH/PH, MH/. PH, PH/PH1, PH/Ph-1 of a vertebra are less than 85 % of the mean ratio in normal women for that vertebral level.

Neu- rogenic claudication is produced by spinal stenosis secondary to slippage and hypertrophy of the ligamentum flavum and facet joints encroaching into the spi- nal canal. Pain along the buttocks and both legs may occur with standing or walking and is frequently associated with dysesthesia, numbness or weakness of the legs.. Most high-grade. This is caused by compression of the cauda equina and subsequent spasm of the ischiocrural mus- cle group.
