Recently posterior cervical foraminotomy (PCF) performed using a minimally-invasive surgery (MIS) approach for cervical radiculopathy due to lateral disc herniation or osseous foraminal stenosis has gained popularity. As 2 dominating MIS techniques, whether FE-PCF or MI-PCF provides superior clinical outcomes remains controversial. ⋯ Cervical radiculopathy, full-endoscopic, microendoscopic, posterior cervical foraminotomy, clinical outcome, complication, reoperation, meta-analysis.

Transforaminal Epiduroscopy in Patients with Failed Back Surgery Syndrome.
Epiduroscopy is a useful diagnostic and therapeutic tool for managing failed back surgery syndrome (FBSS). The conventional approach is via either the sacral hiatus or the interlaminar. Major causes of FBSS include epidural fibrosis, disc herniation, and stenosis. When these problems are located at the intervertebral foramen level, it can be difficult to reach the lateral recess and the foramen with the epiduroscope. Transforaminal epiduroscopy could be a useful alternative approach in patients with FBSS located at the foraminal level. ⋯ Epidural, epiduroscopy, chronic pain, spinal cord, back surgery.

Pain arising from the lumbar facet joints is a common cause of axial back pain in adults. Radiofrequency neurotomy (RFN) of the medial branches of the spinal dorsal rami has been used as a treatment option. The most common side effect is transient, localized, burning, neuritic-type pain, termed post-neurotomy neuritis (PNN). Corticosteroids have been administered through the radiofrequency cannula after neurotomy to prevent PNN, but no study has examined the effects of this on PNN. ⋯ Radiofrequency neurotomy, radiofrequency ablation, neuritis, corticosteroid, lumbar facet pain, post neurotomy neuritis.

Spinal cord stimulation (SCS) relieves pain by delivering doses of electric current to the dorsal column of the spinal cord and has been found to be most effective in the treatment of neuropathic pain. Psychological distress is a significant risk factor for the development of chronic pain and has been found to affect the outcome of SCS. Childhood trauma is a risk factor for chronic pain, but has not previously been studied in SCS patients. ⋯ Spinal cord stimulation, the Trauma and Distress Scale, chronic pain, childhood trauma, childhood abuse, childhood neglect, chronic back pain, back pain, psychological distress, neuropathic pain.

OPRM1 Gene Interaction with Sleep in Chronic Pain Patients Treated with Opioids.
The experience of chronic non-cancer pain (CNCP) is one of the most common reasons individuals seek medical attention. Patients with CNCP frequently experience concomitant sleep-related problems. ⋯ OPRM1, pharmacogenetics, MOS-Sleep, opioids, chronic noncancer pain, sleep related problems, sleep problem index SLP-6 and SLP-9.
