Yes, there will be limitations now that the pec minors are not able to support certain arm movements. I am not able to tie my shoes well or carry anything 'away' from my body.

basically anything that requires pulling apart (opening a package of coffee, making a bow with shoelaces, etc) OR pushing hands together (remember isometrics to make chest muscles bigger?, or picking up a box, or a child) is not possible for me now.

also, your sternum and shoulder muscles will be compensating for the loss of stabilization the pec minors give - so these can become weakened and even torn. be cautious and much more reserved in your movements!
