Final answer:
A malunion is a fracture that heals in an expected time frame but in an unsatisfactory position.
Step-by-step explanation:
A malunion is a fracture that heals in an expected time frame but in an unsatisfactory position. It occurs when a broken bone heals in a misaligned or deformed position. Unlike a delayed union, which is when a fracture takes longer than expected to heal, or a nonunion, which is when a fracture fails to heal at all, a malunion is a healing process gone wrong despite the expected timeframe of healing.
