How long does it take to heal a fractured tibia?

2-3mo: While most bones heal on average in 6 wks, the tibia is prone to delayed healing or even non healing. Partially as this bone is not fully encased in vascular muscle tissue and vascularity= healing. It isn't unusual for this bone to take upwards of 3+ mo to heal. And in adults often warrants surgery as well to stabilize the break while it heals.

Varies: It varies quite a bit based upon the type of fracture, but in general about 8-12 weeks. Nicotine and NSAIDs should be avoided as theses can slow bone healing.
