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 ...
As deep gluteal syndrome is defined as entrapment of the sciatic nerve, patients will have pain along the distribution of the nerve, also known as sciatica. [6] These general sciatica symptoms include unilateral, though sometimes bilateral, radiating pain or dysthesias in the affected legs.
A heavily scrutinized anatomic variation involves sciatic nerve branching around the piriformis using the 6 category classification first described by Beaton and Anson. In this classification, the normal anatomy (type A) seen in about 80% of people is where the sciatic nerve passes under the piriformis muscle at the greater sciatic notch.
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).
When the piriformis shortens or spasms due to trauma or overuse, it is posited that this causes compression of the sciatic nerve. [16] Piriformis syndrome has colloquially been referred to as "wallet sciatica" since a wallet carried in a rear hip pocket compresses the buttock muscles and sciatic nerve when the bearer sits down. Piriformis ...
Sciatic nerve exploration can be done by endoscopy in a minimally invasive procedure to assess lesions of the nerve. [12] Endoscopic treatment for sciatic nerve entrapment has been investigated in deep gluteal syndrome. Patients were treated with sciatic nerve decompression by resection of fibrovascular scar bands, piriformis tendon release ...
Extensive scar tissue formation is a major cause of nerve entrapment, and for deep gluteal syndrome (entrapment of the sciatic nerve in the deep gluteal space), it's the most common cause. [11] While the concept of scar tissue causing traction injuries is widely accepted, [ 2 ] its role is more complex than strictly causing stretching injuries.
As cutaneous nerves cover all areas of the skin, and any surgery which requires incisions may inadvertently cause injury or scarring, now entrapping a cutaneous nerve. [15] A common tradeoff when electing to a neurectomy is that numbness along the nerve distribution is expected.
