Previous surgical procedures for the treatment of thoracic myelopathy (TM) due to ossification of the ligamentum flavum (OLF) were accompanied by significant trauma and risk. ⋯ Translaminar osseous channel-assisted p-PEF technique, with less tissue trauma and impact on the stability of the spine, can provide adequate decompression and satisfying outcomes in the treatment of OLF-related TM and should be considered as an alternative procedure for isolated OLF.

A Pilot Study of Full-Endoscopic Annulus Fibrosus Suture Following Lumbar Discectomy: Technique Notes and One-Year Follow-Up.
An annulus fissure or defect will inevitably be left on the posterior annulus fibrosus after almost all kinds of lumbar discectomy, which may lead to unsatisfying postoperative pain relief and recurrence of the disc herniation. ⋯ Full-endoscopic lumbar discectomy and annulus fibrosus suture through either the transforaminal or interlaminar approach are safe and effective minimally invasive spinal surgery techniques that can reduce the recurrence rate of lumbar disc herniation after full-endoscopic lumbar discectomy.

Interventional procedures are offered routinely to patients seen in McGill University's interdisciplinary cancer pain management program. However, publications on these procedures are scarce, making it difficult to predict which patients may benefit from them. ⋯ In this cohort of cancer pain patients, interventional cancer pain procedures provided effective pain relief and other benefits, including pain relief, reduced burden of symptoms, and reduction of opioid intake, while demonstrating a favorable safety profile. Patients with poorer ratings of depression and fatigue derived less benefit from procedures, suggesting that offering such procedures as part of patients' treatment plan would be sensible, rather than leaving interventions for later stages.

Lumbar facet joints are a clinically important source of chronic low back pain. There have been extensive diagnostic accuracy studies, along with studies of influence on the diagnostic process, but most of them have utilized the acute pain model. One group of investigators have emphasized the importance of the chronic pain model and longer lasting relief with diagnostic blocks. ⋯ This study demonstrated that the chronic pain model is more accurate and reliable with concordant pain relief. This updated assessment also showed prevalence and false-positive rates of 34.1% and 49.8%.

Discogenic pain is recognized as the most important and most common cause of low back pain (LBP). Intradiscal pulsed radiofrequency (ID-PRF) is used for the treatment of chronic discogenic pain. ⋯ ID-PRF was shown to be effective for the treatment of discogenic LBP regardless of duration of ID-PRF application (7 vs. 15 minutes).
