To examine the incidence of percutaneous spinal cord stimulator lead migration, given current hardware and surgical technique. ⋯ The rate of lead migration observed in our practice was considerably lower than previously published estimates of clinically significant lead migration or revision for lead migration (13%-22%). However, our study did not determine the reason for the decreased rate, which may be influenced by current hardware and implant techniques.

Conversion rates from trial leads to permanent spinal cord stimulation (SCS) systems have recently come under scrutiny. Our goal was to examine the rate of conversion from trial lead to permanent system placement as well as identify factors associated with successful SCS conversion. ⋯ In this study of a national cohort of patients, we identified specific factors associated with higher conversion rates, along with significant geographical variation. In general, there is a need for better patient selection by physicians who practice neuromodulation.
