Bones from arm and tibia where odd parts dislodged (5)
I believe the answer is:
radii
'bones' is the definition.
(radius is a kind of bone)
'arm and tibia where odd parts dislodged' is the wordplay.
'where odd parts dislodged' indicates alternate letters (the letters in odd-numbered positions are removed).
'arm'+'and'+'tibia'='armandtibia'
The alternate letters of 'armandtibia' are 'RADII'.
'from' is the link.
(Other definitions for radii that I've seen before include "more than one spoke" , "Half diameters" , "Lines drawn from a circle's centre" , "parts for arms" , "Straight lines from the centre to the surface of a sphere" .)
