Treatment for most stress fractures is NSAIDs, restriction of activity, and time. Immobilization and non-weightbearing status are seldom required. Exceptions are stress fractures of the navicular, 5^th metatarsal, and femoral neck.  These bones have avascular centers and healing may be prolonged, so immobilization and non-weight bearing status is recommended (4-6 wks for navicular and up to 20 wks for 5^th metatarsal). All require outpatient referral to an orthopedist.
