The suprascapular nerve (SSN) is an important nerve that contributes to shoulder joint sensation and movement. The anterior suprascapular nerve block (aSSNB) has the potential for noninferior analgesic effect compared with the interscalene block while preserving respiratory function. This study investigated the median effective volume (MEV) of 0.375% ropivacaine in aSSNB for analgesic effect among patients undergoing arthroscopic shoulder surgery. ⋯ To produce effective analgesic effect, the MEV50 is 6 mL, and the MEV95 is 13.88 mL in patients undergoing arthroscopic shoulder surgery who receive an aSSNB using 0.375% ropivacaine for analgesia.

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.

Orthobiologics have shown promise in repair, restoration and regeneration of damaged and degenerated spine, joint and musculoskeletal tissues. The role of MSCs is to reduce inflammation, gliosis, and oxidative stress, while encouraging angiogenesis, neuronal proliferation, cell survival, and differentiation. While autologous MSCs have homologous advantages, they present with challenges related to donor predisposition, harvesting skills, and processing times. In this regard, allogenic MSCs show promise, but face ethical challenges, contamination, and survival risks. Ongoing efforts to overcome challenges and enhance performance include bioprinting, tissue engineering, artificial intelligence, nanotechnology, and microenvironmental alteration, among many others. Genetically programmed MSCs are being explored and tissue regeneration is now considered a real possibility. In this article, we discuss some of the leading-edge technologies in the process of being developed and perfected for widespread clinical application. ⋯ The role of MSCs in regenerative medicine is still emerging, but their promise for spinal cord injury and other disorders of the spine is clear. Using allogenic or autologous MSCs can help stimulate healing and neural regeneration remains a tantalizing possibility.

In the medical setting, clinicians frequently attend to patients with chronic musculoskeletal pain. Recent literature demonstrates diet may play a role in inflammation and musculoskeletal pain. ⋯ Clinicians can play a role in the well-being of patients with chronic musculoskeletal pain through holistic interventions such as a dietary emphasis on plant-based regimes. Further research is necessary to elucidate the relationship between diet, inflammatory markers, and disease states, as well as the safety and contraindications of these dietary changes.

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.
