How long does it take a fatigue fracture of the pars to heal?

• A. 2-3 weeks
• B. 6-8 weeks
• C. 12-16 weeks
• D. 6-8 months

Answer: (B)

Fatigue fracture of the pars interarticularis heals with rest and stability, especially in young athletes. The bone needs time to form callus and remodel, and with appropriate immobilization, healing typically occurs in about six to eight weeks. Shorter healing times don’t allow enough bone healing, while much longer periods (like several months) are unlikely unless there are complications or delayed healing. So the standard healing window is roughly six to eight weeks.
