With all that swinging around at high speeds that he does, I think that one of Spider-Man’s powers is the ability to not have his arms constantly pop out and dislocate.
Henchmen for Hire
a webcomic in a world of Superheroes and Supervillains by Jeff Langcaon
Spider-Man has actually run into trouble with that, when he tried to web-sling while his strength was on the fritz. So, yes, it’s a side-effect of his other powers.
I like the attention to detail/explaination of grapler impossibilty. But yeah, generally super strength works in both senses of the word. You’re strong (Can lift heavy weights), and you’re strong (Resistant to damage)!

I saw today’s comic and I couldn’t help but see this. I had to share.
