No, sadly I can't. It seems that most of them that target that area are off-limits to me :( I've not tried the pronated triceps extensions, I will experiment and see if I can do that without pain, thanks for the link!
Some of my training partners are amazed that I can do deadlifts and front squats as well as I do - but the nature of my mechanical shoulder issue makes them highly stable in those positions so I can knock them out without any problem (thankfully).
