Percutaneous leads for spinal cord stimulation (SCS) are routinely placed in the dorsal epidural space with the goal of targeting the afferent sensory neurons located dorsally in the spinal cord. The efferent motor neurons leading to the skeletal muscles are located ventrally to the spinal cord.
A randomized clinical trial investigating high frequency spinal cord stimulation delivered at 10 kHz (HF10) has shown that this paresthesia-independent therapy is effective and safe in an FBSS population with both back and leg pain [1, 2] for up to 24 months.
In this case report, a description of a patient with a percutaneous lead placed unintentionally in the ventral epidural space that elicited good pain relief.
