Chronic midline low back pain is the number one reason for disability in the United States despite the prolific use of medical and surgical interventions. Notwithstanding the widespread use of epidural spinal cord stimulators (SCSs), there remains a large portion of the population with inadequate pain control thought to be because of the limited volume of stimulated neural tissue. Intradural SCSs represent an underexplored alternative strategy with the potential to improve selectivity, power efficiency, and efficacy. We studied and carried out development of an intradural form of an SCS. Herein we present the findings of in vivo testing of a prototype intradural SCS in a porcine model. ⋯ Chronically implanted intradural device in the porcine model demonstrated safety and feasibility for translation into humans.

An epidural nerve block injection is the most common modality of treatment for control of low backache associated with radiating pain. Epidural catheter injections are also widely used by pain physicians to control cancer pain. Epidural catheters could be associated with procedure-related complications, such as epidural hematoma, epidural abscess, and post-dural puncture headache, and rare complications, such as shearing or breakage of the catheter tip. In this report, we describe the full-endoscopic removal of a sheared epidural catheter fragment. ⋯ Interlaminar full-endoscopic procedure could be used for the removal of the retained epidural catheter as a practical option.

To evaluate change in fear of movement and the relationship of fear of movement and pain intensity to low back disability and general health-related quality of life over a 2-year period. ⋯ We found that greater levels of fear of movement were related to greater levels of low back disability, following lumbar spine surgery, in a longitudinal study. This shows the need to address fear of movement in prehabilitation/rehabilitation pre- or postsurgically to improve health outcomes for patients who undergo lumbar spine surgery.
