Exactly. Christopher (my son) has/had a subluxed shoulder which he just had corrective surgery for. His humeral head was slightly malformed which was making his shoulder blade (scapula) "wing", and not allowing him to come up higher than 90 degrees with his arm. Because of the mispositioning of his shoulder, he didn't/couldn't put the correct pressure on his arm to crawl correctly.
Think of it this way... a normal shoulder socket looks like an ice cream cone with the ice cream on top. From what we saw on the MRI, Christopher's shoulder had the ice cream at about a 10:00 position, so he couldn't get correct positioning unless he was braced and the shoulder was "put" into position.
We initially did the botox to get him to bend his arm at the elbow and put his hand to mouth. Prior to this he was getting to his hand to his mouth by coming from the side which is because his triceps and brachial radialis were much stronger than his biceps, which was needed to get the correct motion. He was going to get a 2nd round of Botox, but Dr. Brushart (from Dr. Belzberg's team) said if he's still doing the hand to mouth the correct way, then it's not necessary.
If you'd like, I can give you Dr. Belzberg's information. He was extremely nice and spent over an hour with us both times we've seen him, and would like to monitor his progress even though we've done the surgery with Kozin. He's pretty honest about whether surgery is needed or not, and we felt comfortable with his information because he was a neurosurgeon familiar with this type of injury where the others (Waters, Kozin, Nath, Grossman, Price) are Orthopedic Surgeons.
Hopefully this sort of makes sense
