A patient on the table. Their action, my fixed points at the scapula. Together we create a specific net movement: the humerus drops inferiorly, decoaptates.
In that moment, tension loads into the capsule, the labrum, the long head of biceps and triceps attachments, the frenulum capsulae. Pressure inside the synovial capsule drops.
I hold that space. I hold that tension.
Then the patient relaxes, and I control what happens next. I delay the release, the tendons, ligaments, and periosteum slowly losing tension while pressure builds back into the synovial compartment.
That delay is the pump.
Fluid moves through the capsule, through the fascia (the tendons and ligaments are fascia), through the collagen tubules and the ECMatrix surrounding them.
This is what decoaptation is for. Not just space. Movement, at the fluid level.
