i have scoliosis where the top of my spine curves to the right. It causes my shoulder blades to look like that. Also i can't bend my head down to see my left nipple.....and one arm has significantly less strength than the other :/
That, m'dear, is his rhomboid muscle, the trapezius is by far bigger and doesn't end in that pointy manner next to the spinal column, but rather terminates at the spinal colum, thereby forming sort of a triangle, with the base following the spinal column to the neck from the lower thoraic vertebraes, with the apex at the shoulder/scapulae, if I recall my anatomy right.
Just saw this, and Im sure you dont care, but why would there be such a defined muscle on one side, and not the other. Also, if you look at the length of the right trap/shoulder, it seems REALLY disproportionate. Maybe just the camera angle?
The rhomboid muscle is fairly small and only works in a limited range, so he could possibly have a slightly different position on his right side vs. his left, thereby inducing tension to his right rhomboid but not left.
