Behind the scenes

• In the GBC version of Harry Potter and the Chamber of Secrets, Lockhart uses this spell, instead of Brackium Emendo, to "fix" Harry Potter's broken arm bones. This seems a hint to his ineptitude as a wizard, as the spell's etymology seems to clearly identify its effects
• The incantation is only uttered by Lockhart in the French and Portuguese translations of the game; in English, Lockhart says "This should fix it".

Appearances

• Harry Potter and the Chamber of Secrets (video game) (First appearance)
