Poor, poor Mr. taz.... Suffering severe back pain at the moment (we've dealt with this before, though), and then suddenly, last night - pop! - he snaps a tendon in his finger... I looked this up, and it's called an “Extensor Tendon Injury” or "Mallet Finger" / "Baseball Finger". (About this injury.)→[More:]

Of course, he had to work first thing this morning (an episode shoot for a TV series with a whole crew, and he's kind of irreplaceable - so it's not the sort of thing he wouldn't show up for unless it was a serious emergency), and of course, it's Sunday. (What is it? Some kind of rule that this stuff has to happen on a Sunday?) So... he's going to try to get to an emergency room today, if possible, though, obviously, it would be better to see an orthopaedic specialist, which won't be possible 'til tomorrow. In any case, in the meantime, we've actually splinted it ourselves (o_O)

So... Any personal experience with this specific injury? Any general advice? It's relatively painless, so we're pretty sure there is no accompanying fracture of the bone.
