Explant rates of electrical neuromodulation devices in 1177 patients in a single center over an 11-year period.
The publication of explant rates has established risk factors and a definitive objective outcome of failure for spinal cord stimulation (SCS) treating neuropathic pain. We present a UK study analyzing explants of electrical neuromodulation devices for different conditions over 11 years in a single center specializing in neuromodulation. ⋯ These data contribute to a growing list of explant data in the scientific literature and give indications of what factors contribute to long-term utilization of electrical neuromodulation devices.

C-arm-Free Circumferential Minimally Invasive Surgery for Adult Spinal Deformity: A technical note.
Circumferential minimally invasive surgery (cMIS), as a technique for reducing the complications of adult spinal deformity surgery, is receiving considerable attention. Conventional cMIS is performed using intraoperative fluoroscopy. In this work, we describe a new cMIS technique without using C-arm fluoroscopy for correcting adult spinal deformities. ⋯ C-arm-free cMIS for adult spinal deformity is a useful technique that reduces percutaneous screw and cage misplacement. With this new technique, the surgeons and the operation room staff can avoid the risk of an adverse event of intraoperative radiation.

Preoperative chronic narcotic use has been linked to poor outcomes after surgery for degenerative spinal disorders in the form of lower health-related quality of life scores, higher revision rates, increased infections, lower likelihood of return to work, and higher 90-day readmission rates. This study evaluated the impact of preoperative chronic narcotic use on patient reported outcome measures following adult spinal reconstructive surgery. ⋯ Chronic opiate use before adult spinal reconstructive surgery was associated with worse pain and disability following intervention. Further work is needed to understand the role of opiate weaning as part of a larger prehabilitation strategy for adult spinal reconstructive surgery.

The clinical course of acute low back pain (LBP) is generally favourable; however, there is significant variability in the prognosis of these patients. A clinical prediction model to predict the likelihood of pain recovery at three time points for patients with acute LBP has recently been developed. The aim of this study is to conduct a broad validation test of this clinical prediction model, by testing its performance in a new sample of patients and a different setting. ⋯ Ethics were granted by the Research Ethics Committee of the Universidade Cidade de São Paulo, #20310419.4.0000.0064. Study findings will be disseminated widely through peer-reviewed publications and conference presentations.
