'linesmen' is the definition.
The definition and answer can be both people as well as being plural nouns.
Maybe there's a link between them I don't understand?

'broken leg is set' is the wordplay.
'broken' indicates anagramming the letters.
'leg'+'is'+'set'='legisset'
'legisset' is an anagram of 'ELEGISTS'.

'by' is the link.

(Other definitions for elegists that I've seen before include "Poets of a kind" , "pensive poems penned by us?" .)
