Don’t Dismiss Chronic Mid-to-Lower Back Pain as ‘Bad Posture’ or ‘Slouching’ — Dr. Moriwaki explains the pathology of thoracic facet syndrome that is increasing among 40s–60s desk workers, and clarifies what stem cell conditioned media periarticular injection into the facet joint can and cannot address between intra-articular inflammatory environment correction and reversal of the joint’s structural deformity itself

Deep, aching pain at the back of the neck after long desk work — how to avoid mistaking cervical facet syndrome for a cervical disc herniation or cervical radiculopathy: Dr. Moriwaki on facet degeneration at C5-6/C6-7, its referred pain to the occiput and interscapular region, and where stem cell conditioned media periarticular injection can address the intra-articular inflammatory environment — and where it cannot correct the underlying structural degeneration itself

sternoclavicular joint arthrosis — not mistaking aching at the junction of the sternum and clavicle from throwing, bench press, and heavy lifting for a distal clavicle fracture sequela, thoracic outlet syndrome, or Tietze syndrome: Dr. Moriwaki organizes the boundary between the intra-articular inflammatory environment that peri-sternoclavicular injection of stem cell conditioned media can target, and the bony deformity itself that it cannot reverse, in men aged 40 and above

Chronic Aching in the Middle of the Instep Isn’t Just a Lingering Sprain — Not Confusing Lisfranc Joint Osteoarthritis (Tarsometatarsal Arthrosis) With Ankle-Sprain Sequelae or Flatfoot Pain: Dr. Moriwaki on Where Stem Cell Conditioned Media Joint Injection Can Address Intra-articular Inflammation and Where It Cannot Correct Bony Deformity
