= Ischias syndrome =
Ischias syndrome (sciatica) is one manifestation of spinal cord disease. It’s characterised by the presence of back pain and radiating pain down the leg, but no other neurological symptoms. It’s caused by compression of the L4 – S1 roots.

The other manifestations of spinal cord disease are cervicobrachialgia, chronic back pain, and lumboischialgia (topic 23A).

== Etiology ==

* Spinal disc herniation (most common)
* Trauma to the back
* Spondylosis (age-related arthritis of the spine)
* Spinal stenosis
* Spinal tumour

== Clinical features ==
These patients have lower back pain and pain in the distribution of the sciatic nerve. The pain radiates down the posterior or lateral aspect of the leg, usually to the foot or ankle.

== Diagnosis and evaluation ==
These patients can be diagnosed based on clinical symptoms and a positive Lasegue sign. Diagnostic imaging is only necessary in case of severe symptoms, as surgery is not indicated otherwise.

== Treatment ==
Treatment is normally supportive, with physical therapy and NSAIDs. If the symptoms are very severe, surgical treatment may be an option. Most cases of disk herniation improve spontaneously without treatment.
