Actually, 1D & 38A weren't hard, but some of the unclued were, as they aren't produced in NA.
Other than the ambiguity at 22D (Doc's trademark), all done except for 32A, which gives a total of nine.
I don't know whether I'm missing something, but according to my Chambers there's only one word that fits and can mean both split and shoulder, and it ends with L.
