אוסטאופורוזיס
Hi,
First of all, please excuse my english, I'm not in israel and dont have a hebrew keyboard.
I'm not sure what you mean by saying your grandfather's right scapula (=shechem) "comes out", but perhaps you mean a situation called "Winging Scapula" which is usually due to muscle weakness, and is definitely treatable by physiotherapy.
, The physiotherapist will examine the entire shoulder girdle for Range-of-Motion deficiencies, muscle length and muscle weakness and will subscribe exercise and stretches to help restore full function.
Good luck,
Adi
