Stress fractures are a frequent cause of lower extremity pain in athletes, and especially in runners. Plain imaging has a low sensitivity. Magnetic resonance imaging (MRI) or bone scan scintigraphy is the criterion standard, but expensive. We present the case of a young female distance runner with left shin pain. Plain radiography was unremarkable. Ultrasound showed focal hyperechoic elevation of the periosteum with irregularity over the distal tibia and increased flow on Doppler. These findings were consistent with a distal tibia stress fracture and confirmed by MRI. Examination of our case will highlight the utility of considering an ultrasound for diagnosis of tibial stress fracture.
应力性骨折是运动员下肢疼痛的常见原因，在跑步者中尤为常见。X线平片敏感性较低。磁共振成像（MRI）或骨扫描闪烁造影是标准检查方法，但费用昂贵。我们报告一例年轻女性长跑运动员左小腿疼痛的病例。X线平片未见明显异常。超声显示胫骨远端骨膜局灶性高回声隆起，表面不平整，多普勒血流增加。这些表现符合胫骨远端应力性骨折，并经MRI证实。对本病例的检查将突出超声在诊断胫骨应力性骨折中的作用。
