A sciatic nerve block is a nerve block that uses local anesthetic to achieve analgesia in the leg. The block works by affecting the sciatic nerve and is used for surgeries at or below the knee. [1] The sciatic nerve is located in the gluteus maximus muscle, where the block is performed. [1] The sciatic nerve can be blocked at different locations.
A nerve decompression is a neurosurgical procedure to relieve chronic, direct pressure on a nerve to treat nerve entrapment, a pain syndrome characterized by severe chronic pain and muscle weakness. In this way a nerve decompression targets the underlying pathophysiology of the syndrome and is considered a first-line surgical treatment option ...
Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
A sciatic nerve injury occurs between 0.5% and 2.0% of the time during a hip replacement. [7] Sciatic nerve palsy is a complication of total hip arthroplasty with an incidence of 0.2% to 2.8% of the time, or with an incidence of 1.7% to 7.6% following revision.
Lateral femoral cutaneous neuralgia, often known as Meralgia Paresthetica, involves neuropathic pain on the outer thigh. The use of a nerve decompression or neurectomy to treat nerve pain along the lateral femoral cutaneous nerve is a firmly established surgical treatment.
These nerves are as long as 1-1.5 meters (sciatic nerve). Most of the substances the axon needs to survive is manufactured in the cell body. [2] The axon's survival depends on its connection with the cell body, supported by the axonal transport mechanisms to carry cellular material. [4]
