你真的了解X线平片上的黑线征吗?
The tibia is the most commonly involved site, and 90% of stress fractures in this bone occur along the distal third of the posteromedial cortex. Anterolateral fractures are relatively uncommon (4.6%), but are at higher risk of delayed healing, nonunion, and progression to complete fracture. On plain radiographs, nonunion is suggested by the “dreaded black line,” a horizontal cortical fracture caused by bony resorption.
