How long does a femur fraction typically take to recover?

3 to 6 months. Duration depends on age of patient, severity and complexity of fracture, location of fracture and method of treatment.
Varies. This varies depending on the location of the fracture (mid bone or closer to the joint), your age, smoking status, health status, and method of treatment (internal fixation, cast, etc). The bone may be healed by 6-8 weeks, but muscle strength and full recovery may take up to a year.
