Adjacent segment disease (ASD) is a common complication following posterior disc decompression and fusion surgery. Percutaneous endoscopic lumbar decompression surgery (PELD) has been used to treat ASD through either a transforaminal or interlaminar approach. However, to our limited knowledge there are no reports comparing the 2 approaches for treating ASD. ⋯ Percutaneous endoscopic lumbar decompression surgery is a feasible option for ASD following lumbar decompression surgery with instruments. Compared with PETD, PEID seems to be a better approach to treat symptomatic ASDs.

Multicenter Study Observational Study
Results From a Prospective, Clinical Study (US-nPower) Evaluating a Miniature Spinal Cord Stimulator for the Management of Chronic, Intractable Pain.
Chronic, intractable, neuropathic pain is readily treatable with spinal cord stimulation (SCS). Technological advancements, including device miniaturization, are advancing the field of neuromodulation. ⋯ This clinical study demonstrated profound leg and low back pain relief in terms of overall pain reduction, as well as the proportion of therapy responders. The study patients reported the wearable aspects of the system to be very comfortable.

Many patients suffer from abdominal and thoracic pain syndromes secondary to numerous underlying etiologies. Chronic abdominal and thoracic pain can be difficult to treat and often refractory to conservative management. In this systematic literature review, we evaluate the current literature to assess radiofrequency ablation's (RFA) efficacy for treating these debilitating chronic pain conditions in the thoracic and abdominal regions. ⋯ A systematic review of the literature supports RFA as a viable option for managing abdominal and thoracic pain. Future randomized controlled trials are needed to investigate the efficacy of the various RFA modalities to ensure RFA is the source of pain relief as a large body of the current literature focuses only on observational studies.

Spinal cord stimulation is a technique in which different types of electrodes are placed in the spinal epidural space for neuromodulation. Surgical paddle electrodes (SEs) are usually implanted by a surgeon by performing open surgery with laminectomy. Recent advances in endoscopic spine surgery provide another option for minimally invasive SE implantation. ⋯ The results of this anatomical study show that the SEs can be satisfactorily implanted in cervical and thoracic segments using the unilateral biportal endoscopic technique.

Percutaneous balloon compression (PBC) has become one of the most common and effective minimally invasive treatments for trigeminal neuralgia (TN). However, the initial and long-term pain outcomes, as well as the complication rates of PBC for patients with TN with concomitant continuous pain (CCP) have yet to be specifically documented. ⋯ This is the first specifically reported experience treating TN with CCP with PBC. PBC can result in significant relief of both episodic and constant pain from TN with CCP. Patients with a longer duration of pain and prior neurodestructive procedures have a higher risk of poor outcomes. The presence of CCP is not associated with pain outcomes and should not be considered a contraindication to PBC.
