27-MAY-2023  AZIZEH HASAN SALEM  60 YEARS RIGHT TARSAL TUNNEL SYNDROME.

 

Anamnesis

bullet

The patient was operated by me 27-March-2023 for severe LCS with right sciatica and weak dorsiflexion right foot. The power of the right foot improved and the scoliotic stance disappeared and the sciatica decreased. The patient is a known case of rheumatoid arthritis and it was explained to her that she could have different locations for triggering rheumatoid arthritis related pain. Then she came 17-May-2023 complaining of severe headache and still having pain both feet more the right heel exacerbating during standing and walking.

bullet

On examination, the patient is limping due to right foot pain. Tinel's sign positive over both more, the right posterior tibial nerve. There is no neurological deficit.

bullet

The patient was sent for investigations and MRI brain had empty sella and EMG confirmed presence of severe Tarsal tunnel syndrome right foot and mild left. The patient was advised to undergo surgery for TTS right side.

bullet

Under G.A, with tourniquet to the right foreleg, 2 separate incisions were done over the projection of the right posterior tibial nerve. In the above incision the posterior tibial nerve was found and neurolysis was achieved, releasing during that the edge of the tarsal tunnel was bisected and through the lower incision the three major divisions of the nerve including the Baxter nerve were identified, released. Using MultiGen, the posterior tibial nerve responded to 2.8 Volt. A bipolar pulsed mode RF with 42 Celsius, 240 sec, 2 Hz and 20 msec duration to the posterior tibial nerve  was achieved using 2 bended catheters 10 mm exposed length. Further bipolar stimulation of the nerve was responding to 1.5 Volts. Routine closure of the wounds after strict hemostasis. She was sent to the ward.

Comments  

bullet

The tarsal tunnel syndrome here manifest itself as local rheumatoid manifestation.

bullet

This is the 258th case using the BPRF mode with MultiGen. This procedure regained routine acceptance.  It became a usual part of the spine and peripheral nerves surgery. Click here for reference.

bullet

It is still unclear to evaluate the differences of pre and post application motor responses. The only sure thing that it tells that the electrodes did not migrate during the procedure and the nerve is functioning properly. The nerve improved to motor stimulation after performed BPRF.

bullet

With accumulation of data, it became clear that the irritated nerve with aberrant currents running in the C fibers up, not only causing no change or elevation of the required voltage to achieve motor response, but they could cause the preoperative weakness. Ablation of such currents results in facilitation of the motor response and improvement of function with disappearance of pain.

bullet

It is unclear why the roots have several motor response with different patients, despite the fact that the neurological status was the same and the anesthesia protocol also the same.

bullet

It could be that the nerve is recovering minute by minute after decompression and this can explain why the motor conductivity is improving after the BPRF application, which require 5 minute session in most cases.

bullet

After the 172d case, the elevation of motor stimulation above 5 V was abandoned to avoid delayed dural tear with subsequent CSF leak, which take place at the contact at the lower electrode shaft with the dura below or above the level of the axilla.

bullet

Before doing motor stimulation in peripheral nerve surgery with tourniquet. always remove the tourniquet before performing motor stimulation.
