... in bed having fractured ankle bone, perhaps covered (9)
I believe the answer is:
blanketed
'covered' is the definition.
(blanketing is a kind of covering)
'in bed having fractured ankle bone' is the wordplay.
'in' indicates putting letters inside.
'having' indicates putting letters inside.
'fractured' indicates an anagram.
'bone' becomes 't' (I've seen this in other clues).
'ankle' anagrammed gives 'lanke'.
'bed' going around 'lanke' is 'blankeed'.
'blankeed' enclosing 't' is 'BLANKETED'.
'perhaps' is the link.
(Another definition for blanketed that I've seen is " Covered all over, as with bed-clothes or snow".)
