Surgical treatment involves placement of an internal screw or screwsĪcross the fracture. Research shows wearing a cast has an 80-100% success rate.Ĭertain patients, including professional athletes, may choose surgical treatment to allow them to return to activity more quickly and reduce the risk of developing another stress injury. Non-surgical treatment includes wearing a cast or boot without weightbearing for 6-8 weeks. First, you must stop the activity that results in the pain of the stress fracture. Non-surgical options to treat navicular stress fractures. Your foot and ankle orthopaedic surgeon may recommend surgical or Imaging beyond X-rays such as CT, MRI, and bone scans can be helpful in showing a stress fracture at the navicular if X-rays can't do this. However, X-rays may appear normal in the early Standing X-rays may reveal a fracture line. Physical examination will show tenderness across the top of the foot. Incorporate stretching, particularly of the calf muscles and Achilles tendon, prior to exercise.Ī history and physical exam are important ways for diagnosing a navicular stress fracture. Do not increase your walking or running distance increments by more than 10% per week. Start your new training routine slowly, especially after a period of relative inactivity. Supportive shoes typically have a stiff sole with lots of cushioning in the shoe, especially at the arch. Select supportive footwear before you start an exercise or training routine and replace your shoes after 300-500 miles of use. There are steps you can take to help prevent navicular stress fractures: Repetitive forces that could result in a navicular stress fracture include running/jumping sports (such as basketball) and similar activities, increased exercise, or even walking after a period of inactivity. The bone may break down because of excess force, underlying bone weakness, or a combination of these two factors. This makes it more susceptible to repetitive forces that canĬause damage. The navicular is covered by cartilage and lacks a rich blood supply, especially at its center. The navicular bone helps transfer force from the ankle to the forefoot (the ball of the foot). Pain usually improves with rest and support but then returns when activity resumes. Patients with navicular stress fractures usually have gradual onset of aching pain across the top and/or middle of the foot. These fractures often are due to overuse, ongoing forces, and/or stress on the bone rather than a sudden injury. A navicular stress fracture is a crack or break in the navicular bone, which is a boat-shaped bone in the middle of the foot.
