Sacral stress fractures in athletes are rare but important to recognize because the symptoms often mimic sciatica and can lead to delay in diagnosis and treatment. The radiographic findings are characteristic and can facilitate early diagnosis and lead to appropriate treatment.
The clinical presentation of runners with sacral stress fractures can mimic disk disease. However, stress fractures in athletes, especially long-distance runners, must be treated differently. The imaging characteristics appear as linear abnormal signal intensity paralleling the sacroiliac joint on MR imaging and linear sclerosis with cortical disruption on CT. Imaging with bone scintigraphy shows increased uptake that parallels the sacroiliac joint.
运动员的骶骨应力性骨折虽罕见，但因其症状常类似坐骨神经痛，可能导致诊断和治疗延迟，所以识别出来很重要。其影像学表现具有特征性，有助于早期诊断并进行恰当治疗。
患有骶骨应力性骨折的跑步者的临床表现可能类似椎间盘疾病。然而，运动员尤其是长跑运动员的应力性骨折必须采用不同的治疗方法。影像学特征在磁共振成像上表现为与骶髂关节平行的线性异常信号强度，在计算机断层扫描上表现为伴有皮质破坏的线性硬化。骨闪烁显像显示与骶髂关节平行的摄取增加。
