Abstract：
UNASSIGNED: Sacral fatigue fractures are a rare injury but should be considered as a differential diagnosis for low back and buttock pain in young adults. Collective reports are limited, most of which have focused on long-distance runners.
UNASSIGNED: To investigate the characteristics of sacral fatigue fractures in adolescents.
UNASSIGNED: Case series; Level of evidence, 4.
UNASSIGNED: We analyzed patient background characteristics, physical examination and imaging findings, and treatment courses of those diagnosed with sacral fatigue fractures using magnetic resonance imaging.
UNASSIGNED: Among 34 patients with sacral fatigue fractures, 15 and 19 were male and female patients, respectively, with an age range of 11 to 19 years (mean age, 15.0 years). Almost all patients were athletes, and 29 patients performed their sport ≥5 times a week. Long-distance runners were the most commonly affected, comprising 7 patients, and participants in other common sports such as baseball (6 patients), basketball (4 patients), and soccer (3 patients) were also affected. Physical examination revealed tension sign (Lasègue test) on the affected side in 6 patients and tight hamstrings in 24 patients. Imaging findings included 18 patients with right-side involvement, 12 with left-side involvement, and 4 with involvement on both sides. In 11 patients, spina bifida occulta was observed at S1 and 8 patients had a history of lumbar spondylolysis with 4 patients having concurrent sacral fatigue fractures. Physical therapy was performed concurrently with the cessation of exercise, and return to exercise was permitted if the pain had been relieved after 1 month. All patients returned to sports at a median of 48 days (range, 20-226 days) after symptom onset. However, 2 patients experienced recurrence (1 patient on the ipsilateral side and 1 patient on the contralateral side).
UNASSIGNED: Sacral stress fractures are not limited to long-distance runners in this population and can manifest as lower back pain or buttock pain in athletes participating in a variety of sports. Although the course of treatment was generally good, the possibility of recurrence must always be considered.

摘要：
■骶骨疲劳性骨折是一种罕见的损伤，但应该考虑作为年轻人腰痛和臀部疼痛的鉴别诊断。集体报告有限，其中大部分都集中在长跑运动员身上。
■探讨青少年骶骨疲劳性骨折的特点。
■案例系列；证据级别，4.
■我们分析了患者的背景特征，体格检查和影像学检查结果，和使用磁共振成像诊断为骶骨疲劳骨折的治疗过程。
■在34例骶骨疲劳性骨折患者中，15和19分别为男性和女性患者，分别,年龄范围为11至19岁(平均年龄，15.0年）。几乎所有的病人都是运动员,29例患者每周运动≥5次。长跑运动员受影响最普遍,包括7名患者，以及其他常见运动如棒球的参与者（6名患者），篮球（4名患者），足球（3名患者）也受到影响。体格检查显示，6例患者患侧有紧张迹象（Lasègue测试），24例患者的腿筋紧绷。影像学检查结果包括18例右侧受累患者，12与左侧参与，4双方都有参与。在11名患者中，在S1观察到隐性脊柱裂，8例患者有腰椎峡部裂病史，4例患者并发骶骨疲劳性骨折。在停止运动的同时进行物理治疗，如果疼痛在1个月后缓解，则允许恢复运动。所有患者恢复运动的中位数为48天（范围，症状发作后20-226天）。然而,2例患者复发（同侧1例，对侧1例）。
■骶骨应力性骨折不仅限于该人群中的长跑运动员，而且可以表现为参加各种运动的运动员的下背部疼痛或臀部疼痛。虽然治疗过程总体上是好的，必须始终考虑复发的可能性。
