Answer

After exhausting conservative treatment, injection is indicated for the treatment of carpal tunnel syndrome, as follows:

  • With the palmar surface of the hand facing upward, inject just proximal to the flexor crease and between the palmaris longus tendon and the flexor carpi radialis tendon. The needle should enter the skin at a 45° angle and be aimed toward the tip of the middle finger.

  • Advance the needle 1 to 2 cm until resistance is felt.

  • Withdraw the needle slightly, and inject the medication. The patient should have mild paresthesias elicited in the distribution of the median nerve. Volume should be minimized to prevent discomfort.
