The purpose of this report is to describe a fifth metatarsal stress fracture that was not detectable using conventional radiographs and was identified with diagnostic ultrasonography (US), confirmed with computed tomography, and followed through symptom resolution with US.Clinical features:
A 68-year-old woman presented to a chiropractic teaching clinic for evaluation of right foot pain. Diagnostic US examination using an 8- to 15-MHz linear array transducer showed increased vascularity, periosteal elevation, and cortical disruption of the proximal diaphysis of the fifth metatarsal suggestive of a stress fracture. The patient was referred to an orthopedic specialist for comanagement.Intervention and outcome:
The patient was treated by an orthopedist who confirmed a stress fracture using computed tomography, and she was fit with a short-leg walking boot. Serial US images were obtained to document fracture healing and exclude complications. After 6 months, the patient was asymptomatic and had resumed all of her daily activities.Conclusion:
We report a case of a proximal fifth metatarsal stress fracture that was visualized with US and followed through symptom resolution by serial examinations.
