'to restock?' is the definition.
Although both the answer and definition are verbs in their base form, I cannot see how one could define the other.

'fractured her spine? left' is the wordplay.
'fractured' is an anagram indicator.
'left' becomes 'l' (common abbreviation).
'her'+'spine'+'l'='herspinel'
'herspinel' anagrammed gives 'REPLENISH'.

'inside' is the link.
