How does your system break down myofascial adhesions, scar tissue and other abnormalities which prevents a persons skeleton being in the perfect position?

Personally, I have a lot of these issues. Chiros have given up on me as any adjustments made to my skeleton do not hold. The tethering from my hip to throat, scapula to throat and other various criss-crosses can not be adjusted or "overridden" by the strong myofascial component.
