  • Sciatica

    Sciatica is when pain is felt going down the leg from the back. This pain may go down the back, outside, or front of the leg. Typically, symptoms are only on one side of the body.Diagnosed by physical examination, and the history of the symptoms. The most applied diagnostic test is the straight leg raise to produce Lasègue's sign, which is considered positive if pain in the distribution of the sciatic nerve is reproduced with between 30 and 70 degrees passive flexion of the straight leg. lumbar disc herniation can be diagnosed by computerised tomography or magnetic resonance imaging.

    Treatment:
    Medications like Anti-inflammatory, Muscle relaxants and Corticosteroids reduce pain by suppressing inflammation around the irritated nerve. Botulinum toxin injections may improve pain and or function. Surgery for unilateral sciatica involves the removal of part of the disc, known as a discectomy,back surger Laminectomy. Treatment of the underlying cause of the compression is needed in cases of epidural abscess, epidural tumors, and cauda equina syndrome.spinal manipulation is an effective treatment for acute sciatica and disc-related pain. Lower Back Pain Home Care and Physical Therapy treatment includes posture correction, back support and good body mechanisms focuses on prevention of injuries or disabilities and relieve pain, promote healing, and restore function and movement.

    Pathophysiology:
    Sciatica is generally caused by the compression of lumbar nerves or by compression of the sciatic nerve. When sciatica is caused by compression of a dorsal radix, it is considered a lumbar radiculopathy. When there is a tear in the anulus fibrosus, the nucleus pulposus may extrude through the tear and press against spinal nerves within the
    spinal cord, cauda equina, or exiting nerve roots, causing inflammation, numbness, or excruciating pain. Inflammation in the spinal canal can also spread to adjacent facet joints and cause lower back pain in the posterior thigh. Pseudosciatic pain can also be caused by compression of peripheral sections of the nerve, usually from soft tissue tension in the piriformis or related muscles.
