The disease of male young adults more common, in recent years
especially common to do office work and the use of computer for a
long time people.
Symptom is: unilateral multiple. The degree of pain and time
constant and the etiology and treatment of disease.
Radicular sciatica
With the cause of onset varies. The most common lumbar disc
herniation, often in force, bending or strenuous activity and other
incentives, acute or subacute onset. A chronic disease. Pain often
from the waist to hips, thighs side, popliteal fossa, lateral lower
leg and foot radiation, a burning or knife like pain, cough and
forceful when the pain can exacerbate, night more.
Patients to avoid nerve stretching, compression, often take a
special sciatic nerve anatomy diagram
Pain reducing posture, such as sleep lying to the contralateral
knee, hip, buckling, standing to Yu Jian side, a cause of the
scoliosis, the curved toward the healthy side, sitting in the hips
to the healthy side inclined, to relieve the nerve root
compression. Traction on the sciatic nerve can induce pain, or
pain, such as Kernig syndrome positive (patient supine, the first
hip flexion and knee at right angles, then lower leg lift.
As a result of flexor spasms, and knee extension restriction and
less than 130 degrees and the pain and resistance ); straight leg
raising test ( Lasegue syndrome) positive (patient supine, lower
limbs, limb into up to 70 degrees Celsius and cause leg pain ).
Sciatic nerve pathways can tenderness, such as lumbar paraspinal
point, point of rump, country point, ankle and metatarsophalangeal
point.
The affected limb of lateral leg and foot dorsum often numbness and
decreased sensation. Gluteal muscle tension relaxation, the
extensor hallucis and flexor pollicis muscle weakness. Achilles
tendon reflex abate or disappear.
Sciatica
They also vary with etiology of disease. Such as a cold or trauma
induced by more acute onset. Pain often from the buttock to the
posterior femoral posterolateral lower leg and foot, lateral
radiography. Walk, activities and traction sciatic nerve pain
exacerbations. Point tenderness at the hip points below, Lasegue
positive and Kernig negative syndrome syndrome of multiple,
scoliosis, bending to suffer from side to reduce the sciatic nerve
trunk pull.
