Abstract
Background and objective: Spinal cord stimulation has been performed frequently in the last years as a neuromodulation technique for the treatment of chronic low back pain. Dorsal column is stimulated with the electrode replaced at epidural region. We applied subcutaneous lead as an adjunct in failed back syndrome patient receiving spinal cord stimulation for limb pain but had inadequate response to back and gluteal pain.
Case report: 65 year old male patient had an operation because of lumbar disc herniation. After the operation he had recieved physical therapy and multiple steroid injections due to his unrelieved pain. He was admitted to our pain clinic with a radiating pain to right gluteal and limb. He was performed spinal cord stimulation. Later on subcutaneous lead was placed on the right cluneal nevre distrubition because of the unrelieved pain. He has a VAS of 1-2 and pain was reduced over 80 %.
Technique: Octad electrode was placed between T8-T10 after the tuohy needle was introduced between L1-L2 intervertebral area. Paresthesia was obtained at right extremity. The boundries of the right gluteal region side has been determined which the paresthesia did not obtaiıned. Octad electrode was placed subcutaneously after the vertical line drawn from the center point. Paresthesia was obtained at all region (pw 390-450 msec, f 10-30 hz).
Conclusion: Subcutaneous electrode replacement can be used as an alternative technique after spinal cord stimulation due to unrelieved pain.
