The use of magnetic resonance imaging in the diagnosis of stress fractures of the foot and ankle: four case reports.
Stress fractures result when bone is subjected to repeated loading which causes fatigue, cracking of the bone, and, eventually, a complete fracture. Stress fractures of the foot and ankle are common injuries affecting a broad range of the population, from the young to the elderly, the fitness enthusiast to the chronically debilitated. The diagnosis of stress fracture is not always obvious because radiographs are often negative, especially on initial presentation. In this report, we present four cases in which, after appropriate initial studies proved inconclusive, magnetic resonance imaging (MRI) was used to establish the diagnosis of stress fracture. We propose that MRI is a useful diagnostic modality in a select group of patients with suspected stress fractures of the foot and ankle.
