All normal humans have their femur attached to the acetabulum via the acetabulofemoral joint. The distal, medial and the superior region of the femur do not rotate independently of each other. Also, the distal part of the femur is attached to a synovial joint, which does not rotate, but only hinges. Hence, mentioning ‘acetabular’ for an ext/int rotation of the leg is moot. On the other hand, it is proper when speaking of impingement or other degenerative diseases as I’ve mentioned before.
What my question is, how did you deduce that the OP had internal/ext rotation on either leg?
“Someone in his position will “favor” their right hip over their left, not vice versa. More specifically, they will be in a state of acetabular femoral internal rotation on their right and external rotation on their left. The pelvis would also expected to be abducted and rotated to the right.”
We were speaking of his spine shape until you threw this curveball… And just wanna point out that if someone did have internal rotation on their right leg, and ext rotation on the left, that it’s more likely that the pelvis be rotated to the left, due to an inactive/inhibited piriformis on the right hip and overactive glute and piriformis on the left.
“Again, the distinction between AF and FA internal rotation is relevant.”
What is the distinction?
“I did not “squeeze it in.” You can expect all anatomically normal humans to favor stance on their right leg because it provides support for their larger, stronger, better-positioned right diaphragm. In cases of situs inversus, this is swapped so you can expect them to favor their left.”
This is quite strange because I personally favor my left. And I attribute that to grappling for nearly two decades, and driving off my left leg when I went in for a double. Strangely enough, a lot of my teammates and rolling partners are the same, vice versa if they are lefty. Maybe we all have situs inversus? It’s very difficult to assume which hip a person would favor in the manner in which you do. From my experience, many athletes who drive off their left leg (ie righty wrestlers and basketball players) favor their left leg/hip.

If you want to discuss, let’s discuss. Hurling your hurt ego won’t get you far. The sole purpose was to lend some help to a dude from New Zealand who asked for advice. Not to berate his or any of our intelligence.
