Percutaneous endoscopic interlaminar discectomy (PEID), which poses advantages for certain types of herniated disc, is gaining wider acceptance in clinical practice. We retrospectively analyzed the efficacy of the PEID technique in treatment of calcified lumbar disc herniation. ⋯ The PEID technique is an effective method in the treatment of calcified lumber disc herniation, although the rate of postoperative dysesthesia is higher in this group during the early postoperative period. Long-term TCM administration may be related to the calcification of herniated lumbar discs.

Randomized Controlled Trial Multicenter Study
MiDAS ENCORE: Randomized Controlled Clinical Trial Report of 6-Month Results.
Patients suffering from neurogenic claudication due to lumbar spinal stenosis (LSS) often experience moderate to severe pain and significant functional disability. Neurogenic claudication results from progressive degenerative changes in the spine, and most often affects the elderly. Both the MILD® procedure and epidural steroid injections (ESIs) offer interventional pain treatment options for LSS patients experiencing neurogenic claudication refractory to more conservative therapies. MILD provides an alternative to ESIs via minimally invasive lumbar decompression. ⋯ NCT02093520.

Headache is one of the most common debilitating chronic pain conditions in patients with mild traumatic brain injury. Conventional pharmacological treatments have not been shown to be effective in alleviating debilitating mild traumatic brain injury related headaches (MTBI-HA). Therefore, the development of an innovative non-invasive therapy in managing MTBI-HA is needed in the field of pain management. Repetitive transcranial magnetic stimulation (rTMS) utilizes a basic electromagnetic coupling principle in which a rapid discharge of electrical current is converted into dynamic magnetic flux, allowing the induction of a localized current in the brain for neuromodulation. The treatment is currently FDA approved for treating depression in the United States. Recent meta-analysis studies have implicated its usage in chronic pain management. ⋯ rTMS offers a non-invasive treatment option for MTBI-HA. The tested treatment protocol was well tolerated by the patients and can be adopted for future randomized controlled studies in further validating the treatment efficacy.

Pulsed radiofrequency (PRF) is a novel nondestructive interventional technique for the treatment of neuropathic pain (NP). However, this intervention is still lack of relevant regulation and the mechanism of action is insofar not clear. Historically, most studies have reported that PRF can relieve reduce hyperalgesia in multiple NP animal models by acting on the dorsal root ganglion. However, a few recent studies have shown that PRF can effectively treat hyperalgesia in pain models by a direct application on injured peripheral nerves. ⋯ The findings suggest that the application of PRF at the impaired SN relieved reduced the CCI-induced NP by through regulating the upregulation of the GDNF expression in the nervous tissues.

Randomized Controlled Trial
Randomized Controlled Study of Percutaneous Epidural Neuroplasty Using Racz Catheter and Epidural Steroid Injection in Cervical Disc Disease.
The efficacy of lumbar percutaneous epidural neuroplasty (PEN) as a minimally invasive technique has been relatively well investigated, but the clinical effectiveness of cervical PEN (C-PEN) has yet to be established. ⋯ C-PEN was superior to C-ESI in terms of better NDI recovery (at 6 months) and greater reduction in VAS score (until 12 months) in treating single level cervical disc herniation. Better outcomes with C-PEN may have been achieved via a more localized selective block in the epidural space closer to the dorsal root ganglion and ventral aspect of the nerve root.
