Reading articles on Pub Med

 Does anyone here use Pub Med?

There's an article I want to read on Dupuytren's treatment, and I don't know how to read it.

I'm willing to pay to read it if I can work out how to do so.  The British Dupuytren Society (if we can afford it) probably need to get access to all these online medical journals.

What I'm not sure of is whether Pub Med has the full article or only the abstract.

How does one access online medical journals - what sort of cost is one looking at?

All advice welcomed.
