What is the treatment protocol for a navicular stress fracture?

The treatment protocol for a navicular stress fracture primarily involves non-weight bearing for an extended period, typically around 6 weeks. This approach allows the fractured bone to heal without the stress of weight bearing, which could otherwise impede recovery and exacerbate the injury. Mobility restrictions are crucial in ensuring that the healing process is not disrupted, as the navicular bone is vital in the structure and function of the foot, particularly in activities that involve running or jumping.

Rest and ice may contribute to symptom management, but they are not sufficient alone for addressing the healing needs of a navicular stress fracture. Surgery is usually not the first course of treatment unless there are complications or the fracture is significantly displaced, which is generally uncommon in stress fractures. Similarly, while physical therapy may be beneficial for rehabilitation after initial healing, it is not the primary treatment in the acute phase of a navicular stress fracture. Therefore, non-weight bearing for 6 weeks is the most appropriate and evidence-based approach in this scenario.
