The use of a nerve decompression or neurectomy to treat nerve pain along the lateral femoral cutaneous nerve is a firmly established surgical treatment. [ 24 ] [ 25 ] However, the more effective treatment between a decompression and neurectomy is still being researched.
Meralgia paresthetica is a specific instance of nerve entrapment. [5] The nerve involved is the lateral femoral cutaneous nerve (LFCN). [6] [7] [4] [8] The symptoms are purely sensory because the LFCN has no motor function. [4] This syndrome can be caused by anything which places prolonged pressure on the LFCN, such as wearing a tight belt.
Identifying the level of entrapment is an important consideration for surgery as decompressing the wrong area will lead to a failed surgery (e.g. performing back surgery for extra-spinal sciatica), [2] [3] failure to treat nerve entrapment early can lead to permanent nerve injury, [4] and the patient may be unnecessarily exposed to surgical ...
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).
Entrapment of the lateral cutaneous nerve of the thigh is caused by compression of the nerve near the anterior superior iliac spine and the inguinal ligament. [2] This causes meralgia paraesthetica (Bernhardt-Roth syndrome). [2] [5] This may be diagnosed with ultrasound, which changes the morphology of the nerve. [1]
Sometimes compression occurs in areas that are not considered tunnels and where a nerve passes between two mechanically stiffer tissue types that can squeeze or pinch the soft nerve. Examples include the lateral femoral cutaneous nerve at the inguinal ligament [8] and the middle cluneal nerves at the long posterior sacroiliac ligament. [9]
It works by affecting the femoral, obturator and the lateral cutaneous nerves. [51] 3-in-1 nerve block is indicated for pain relief for hip fractures. The femoral nerve block is indicated for femur, anterior thigh, and knee surgery. [53] It is performed slightly inferior to the inguinal ligament, and the nerve is under the fascia iliaca. [53]
Dysfunction of the superior cluneal nerves is often due to entrapment as the nerves cross the iliac crest – this can result in numbness, tingling or pain in the low back and upper buttocks region. Superior cluneal nerve dysfunction is a clinical diagnosis that can be supported by diagnostic nerve blocks. [1]
