When treating nerve entrapments, the procedure known as nerve hydro dissection (HD) includes injecting an anesthetic, saline, or 5% dextrose in water to separate the nerve from the fascia, surrounding tissue, or nearby structures. According to animal studies, even minor compression may be sufficient to start and maintain neuropathic pain. The release of nervorum or the reduction of vasa nervorum may be related to the mechanical benefits of HD. The detection of pathologic nerves can be done visually or through ultrasonic imaging. The most common and secure technique for nerve HD is in-plane. Based on preliminary comparative-injectate literature, five percent dextrose might be recommended as the preferred injectate, but more research is essential.

Nerve compression syndrome, also known as compression neuropathy, nerve entrapment syndrome, or imprisoned nerves, is treated via nerve hydro dissection. Whatever term you use, this issue arises when joints or other tissues strain against peripheral nerves (nerves outside of the brain and spinal cord). A variety of symptoms, including tingling, numbness, muscle weakness, and scorching pain, might result from that pressure.

To release blocked nerves in the past, surgery was routinely utilized. However, a nonsurgical approach known as nerve hydro dissection has gained popularity recently. It entails using exact, ultrasound-guided injections of a fluid (usually water diluted with a small amount of dextrose) to create a cushion between the tissue pressing on a trapped nerve and the trapped nerve itself. Significant symptom relief is the end result.


Nearly every peripheral nerve can become entrapped. The following standard conditions may be treated by nerve hydro dissection :

  • A pinched nerve in the wrist is the result of carpal tunnel syndrome.
  • Chest wall outlet syndrome:- Between the clavicle and the first rib, entrapped nerves.
  • Entrapment of the radial nerve or the posterior interosseous nerve (PIN):- The armpit to wrist nerve, or one of its branches, being entrapped.
  • Pronator teres syndrome:- Muscle entanglement of a significant arm nerve.
  • Chronic cubital tunnel syndrome:- On the inside of the elbow is irritation and trapping of the ulnar nerve.
  • Meralgia paresthetica:- It refers to compression of the lateral femoral cutaneous nerve, a leg nerve that emerges from the pelvis and functions on the outer side of the thigh.
  • The Piriformis syndrome is sciatic nerve irritation brought on by a buttock muscle.

  • Entrapment of the peroneal nerve, which starts below the knee and may result in discomfort at the top of the foot, is known as peroneal nerve entrapment syndrome.
  • Syndrome of the tarsal tunnel: Ankle discomfort from posterior tibial nerve compression can be very painful.
  • A swelling of the tissue surrounding a nerve supplying the toes is known as Morton’s neuroma.
  • Scar neuropathy: Damage to the peripheral nerves brought on by scar tissue.
