One the drawbacks of the dorsal column stimulation (DCS) method is that the electrode
array and the subsequent electrical stimulation induce proliferation of connective
tissue between the array and the dura. In this case report, a patient is presented
in whom dural thickening after placement of a DCS electrode array at the C2-C3 level
prevented sufficient electrical penetration and thus resulted in treatment failure.
The thickened dura was excised and the electronic array was used as a dural substitute.
This resulted in efficient DCS and resolution of the pain symptoms.
