All his shoulder problems stem from that injury. He's had multiple subsequent dislocations (including the high five incident and one in October) and two surgeries - the forthcoming one will be his third. Even a brief look at medical literature shows this isn't a surprise, recurrence is common.That hasn't been his only injury though right?
Although there's probably not a fast bowler on the planet reaching 140 clicks or over who doesn't have a lengthy injury record, so his build probably doesn't have anything to do with it.
Does the idea that diving around in the field (or the expectation thereof) is causing more injuries to bowlers hold any water though simply because that's how he hurt his shoulder? Probably not. Unless there is conclusive evidence to suggest otherwise.
He's had four hamstring injuries and one surgery, but I don't see how that would be trigged by his not being tall. He actually put on a considerable amount of muscle to try stabilise his shoulder taking his weight from 75 to 81 kg, which is on the heavy side for a fit person of his height (for comparison, in this article Starc says he weighs 93 kg max, he's 7" taller). The extra weight could even be a cause, his legs would take more force. He's also had a side strain, extra muscle could be a factor here because it can be at the expense of flexibility, which is very important for a fast bowler. His action is subtly more open and less fluid that it used to be.
As for diving around the field, a dislocated shoulder can happen if it's not done well or something goes wrong. It's not a bowler exclusive thing, though Nathan Hauritz in 2011 was the first example I heard of and they may be at greater risk because they tend to field in the outfield rather than the slips or ring. O. Pope, Coulter-Nile, Rauf, Iyer and Lynn have all done it. I knew of some instances at my club when I played. It's a very real risk and just from examples I could find diving in the field seems to be the main cause in cricket. Therefore if you don't do it that risk would largely be eliminated. But players are obviously expected to because of the imperative of saving every possible run in limited overs cricket.
