Christina:

Snape tells Cissy and Bella that Dumbledore "sustained a serious
injury."  I agree that he wanted LV to think DD weaker than he
actually was.  BUT, IIRC, he does not disclose the nature of the
injury.  Voldemort surely must know a thing or two about Horcruxes,
having made quite a few of them himself.  An "injury" may signal
simple weakness to Voldemort, but if charbroiling is a common injury
facing Horcrux-destroyers - well then, Dumbledore surely wouldn't want
Voldemort to know about *that*.  So...we're still left with the tricky
question as to why DD practically flaunts his injury all year,
although I suspect that JKR meant to put a lot of focus on the hand
simply as a clue to the reader.
