  2. Neurogenic claudication - Wikipedia

    en.wikipedia.org/wiki/Neurogenic_claudication

    Surgical treatments are predominantly used to relieve pressure on the spinal nerve roots and are used when nonsurgical interventions are ineffective or show no effective progress. [ 1 ] [ 11 ] Diagnosis of neurogenic claudication is based on typical clinical features, the physical exam, and findings of spinal stenosis on computer tomography (CT ...

    en.wikipedia.org/wiki/Failed_back_syndrome

    The remaining cases developed pathology at a different level, or on the opposite side, but at the same level as the surgery was performed. In theory, all failed back patients have some sort of nerve injury or damage which leads to a persistence of symptoms after a reasonable healing time. [59] [60] [132]

  4. Facet syndrome - Wikipedia

    en.wikipedia.org/wiki/Facet_syndrome

    Typically, the pain is worsened by stress on the facet joints, e.g. by lumbar extension and loading (the basis of the Kemp test) or lateral flexion but also by prolonged standing or walking. [citation needed] Pain associated with facet syndrome is often called "referred pain" because symptoms do not follow a specific nerve root pattern. This is ...

  5. Spinal stenosis - Wikipedia

    en.wikipedia.org/wiki/Spinal_stenosis

    Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [6] Symptoms may include pain, numbness, or weakness in the arms or legs. [1] Symptoms are typically gradual in onset and improve with leaning forward. [1]

  6. Cauda equina syndrome - Wikipedia

    en.wikipedia.org/wiki/Cauda_equina_syndrome

    The nerve roots from L4–S4 join in the sacral plexus which affects the sciatic nerve, which travels caudally (toward the feet). Compression, trauma or other damage to this region of the spinal canal can result in cauda equina syndrome. [citation needed] The symptoms may also appear as a temporary side-effect of a sacral extra-dural injection. [9]

  7. Dural ectasia - Wikipedia

    en.wikipedia.org/wiki/Dural_ectasia

    Moderate-to-severe cases can cause radicular pain in the legs caused by nerve root compression. [5] The symptoms are usually exacerbated by upright posture and often, but not always, relieved by lying down. Postural headaches can be related to spontaneous spinal cerebrospinal fluid leaks. [6] However, in many patients, dural ectasia is ...

  8. Disc herniation - Wikipedia

    en.wikipedia.org/wiki/Disc_herniation

    If the herniated disc is in the lumbar region, the patient may also experience sciatica due to irritation of one of the nerve roots of the sciatic nerve. Unlike a pulsating pain or pain that comes and goes, which can be caused by muscle spasm , pain from a herniated disc is usually continuous or at least continuous in a specific position of the ...

  9. Neurolysis - Wikipedia

    en.wikipedia.org/wiki/Neurolysis

    The general technique of administering lumbar sympathetic neurolysis involves using three separate needles rather than one because it allows for better longitudinal spread of the chemicals. [13] Complications can arise from this procedure such as nerve root injury, bleeding, paralysis, and more. Complications have been seen to be diminished ...
