Comparative Study
Rates of lead migration and stimulation loss in spinal cord stimulation: a retrospective comparison of laminotomy versus percutaneous implantation.
Neuromodulation has been used to treat neuropathic pain. Leads have been implanted using laminotomy or percutaneous approaches. Laminotomy implantation has been shown to be superior in terms of lead migration when compared to percutaneous implantation. Lead migration has been reported as high as 68% with the percutaneous approach. Because of this, newer anchors have been developed but not tested in vivo. ⋯ Rates of stimulation loss and radiographic lead migration are similar for both laminotomy and percutaneous implantation. Time to loss of stimulation was not statistically different in either group, although there was a trend toward laminotomy leads migrating earlier. Lead type and laterality of symptoms do not affect lead migration rates. The effect of the level of implant and diagnosis was indeterminate.

Multicenter Study Clinical Trial
Infection control practices (safe injection and medication vial utilization) for interventional techniques: are they based on relative risk management or evidence?
Recently, multiple regulations and recommendations for safe infection control practices and safe injection and medication vial utilization have been implemented. These include single dose and multi-dose vials for a single patient and regulations. It is a well known fact that transmission of bloodborne pathogens during health care procedures continues to occur because of the use of unsafe and improper injection, infusion, and medication administration. Multiple case reports have been published illustrating the occurrence of infections in interventional pain management and other minor techniques because of lack of safe injection practices, and noncompliance with other precautions. However, there are no studies or case reports illustrating the transmission of infection due to the use of single dose vials in multiple patients when appropriate precautions are observed. Similarly, the preparation standards for simple procedures such as medial branch blocks or transforaminal epidurals have not been proven to be essential. Further, the effectiveness or necessity of surgical face masks and hats, etc., for interventional techniques has not been proven. ⋯ There were no infections of any significance noted in approximately 3,200 patients with over 18,000 procedures performed during a 20-month period in an ambulatory surgery center utilizing simple precautions for clean procedures with the use of single dose vials for multiple patients and using safe injection practices.
