Tarsal navicular stress fracture in a young athlete: case report with clinical, radiologic, and pathophysiologic correlations.

BACKGROUND Tarsal navicular fractures are uncommon but important causes of foot pain. Being alert to this condition can help prevent a delay in the diagnosis. METHODS A literature search of MEDLINE was undertaken, and a case report of an adolescent with tarsal navicular stress fracture is described. RESULTS AND CONCLUSIONS Tarsal navicular fractures are often misdiagnosed for months. Because plain radiographs are unreliable, the diagnosis of tarsal navicular fractures requires the use of bone scan, fine-cut computed tomographic scans, or magnetic resonance imaging. Treatment requires strict non-weight-bearing activities to avoid complications. When the alert primary care physician can diagnose this condition, treatment of tarsal navicular fractures can be effective and rewarding.
