Ultrasound guided Nerve Hydrodissection MIPSI

MIPSI or Minimally invasive pain and spine interventions is a broad term which encompasses all the Non-invasive and minimally invasive interventions done by the interventional spine and pain physicians for myriad of conditions right from Musculo-skeletal disorders like back pain, neck pain, knee pain etc.

Nerve entrapment syndromes are one of the common causes of Peripheral mono-neuropathies. If other systemic causes of neuropathy are ruled out, Ultrasound guided nerve hydrodissections can play a pivotal role in management of these conditions.

Some commonly entrapped nerves in our body are


  • Median nerve (Carpal tunnel syndrome, Pronator teres syndrome)
  • Posterior Tibial nerve (Tarsal tunnel syndrome)
  • Lateral Femoral Cutaneous nerve (Meralgia paresthetica)
  • Radial nerve (Radial tunnel syndrome)
  • Ulnar nerve (Cubital tunnel syndrome, Guyon’s canal syndrome)
  • Suprascapular nerve, Dorsal scapular nerve
  • Peroneal nerve
  • Pudendal nerve (Pudendal neuralgia)
  • Ilio-inguinal/Ilio-hypogastric nerve
  • Anterior Cutaneous nerve entrapment syndrome (ACNES)

How Ultrasound guided Nerve hydrodisscetion MIPSI helps relief pain?


This procedure is characterized by actual identification of the compressed segments of the nerves with the help of Ultrasound scanning and then hydrodissection of the nerve with the help of 5% dextrose. This process of hydrodissection involves injection of 10-20 ml of this hypertonic solution of dextrose around the nerve which separates the nerves from the surrounding tissues, fibrous bands, fascia or any other adjacent structures.

This releases the pressure over the nerve which facilitates the recovery in the vascular supply to the nerve and hence initiating the process of remyelination or healing.




When will the medication begin to work?

Patient can start appreciating the effect of the medications 3-4 days post-procedure and maximal effect is achieved over a period of 3-4 weeks.

How many times this procedure has to be repeated?

Most patients need only one injection, however, some patients may need repetition of the procedure. Decision to repeat the procedure is taken by your doctor looking at the relief percentage from previous procedure.

Will I require hospitalization for this procedure?


No. This is a Day care procedure. Patient is advised about the Pre-procedure precautions before- hand. On the day of the procedure, patient arrives 2 hours before the procedure and is discharged same day after 2 hours of monitoring.
