Testing, Treatment & Recovery - Lower Extremity Nerves
A neurosensory test can show how much feeling is left in the feet by using a two-prong testing device. It determines:
- The pressure needed to feel the two prongs
- The minimal distance felt between the two prongs
- A nerve conduction study may also performed to determine exactly where the nerve is compressed by measuring the conduction velocity of an electrical current through the nerve.
During an outpatient procedure compressed nerves are released by:
- Making two small incisions behind the ankle, on top of the foot and just below the outside of the knee
- Freeing up and mobilizing the nerves
- Restoring blood flow inside the nerve, which gives the nerve the ability to heal itself
- The leg is placed in a soft boot made of thick cotton and gauze
- Pressure can be placed on the foot by walking with the use of a walker over short distances
- Rest is recommended, and the feet should be kept elevated above the level of the heart
- Dressing is removed after one week
- Sutures are removed after three weeks
- The burning pain should be relieved within days after surgery. The numbness improves as the nerve regenerates, depending on the amount of damage to the nerve. Patients improve up to one and a half years after surgery.
