In a distant era, a mysterious malady called sacroiliac joint syndrome emerged, an enigmatic troublemaker that inflicted severe discomfort in the lower back. It ruled the pain and earned its illustrious moniker, the "SI Joint Epoch." However, in 1934, the tides shifted dramatically with the arrival of Jason Mixter, MD, which revealed a groundbreaking treatise on intervertebral disc lesions, triggering the "Dynasty of the Disc." This seismic transformation cast doubt on the very existence of SI joint syndrome, leaving the medical community in a state of perplexity. But amidst the uncertainty, a visionary manipulative osteopath named Fred Mitchell Sr. emerged from the shadows, reigniting curiosity with his innovative biomechanical framework. Thus, a new era of exploration and enlightenment was set in motion.
