Abstract：
UNASSIGNED: Sumo wrestling is a traditional sport in Japan and becoming popular worldwide. Risk factors for lower back injuries in sumo wrestlers are heavier weight and larger body mass index (BMI). The mawashi (loincloth belt) worn by sumo wrestlers has been shown to restrict motion of the lumbar spine.
UNASSIGNED: To study the effects of sumo wrestling on the lumbar spine of high school and freshmen collegiate wrestlers, investigating the relationship between radiological findings, wearing of the mawashi during training, and lower back symptoms.
UNASSIGNED: Case series; Level of evidence, 4.
UNASSIGNED: From 2001 to 2017, a total of 197 members of the Japanese Sumo Federation (55 high school and 142 college freshman students) underwent routine radiographic examination of their lumbar spines and answered a questionnaire regarding lumbar symptoms. Wrestlers were classified as symptomatic and asymptomatic based on responses to a custom questionnaire. We used the unpaired t test to evaluate patient demographics and the chi square test to analyze radiographic lumbar spine abnormalities between symptomatic and asymptomatic wrestlers.
UNASSIGNED: The wrestlers\' mean height, weight, BMI, and duration in the sport were 174.0 ± 6.7 cm, 107.1 ± 22.4 kg, 35.2 ± 6.4, and 8.0 ± 3.2 years, respectively. There were 91 participants in the symptomatic group (46.2%) and 106 (53.8%) in the asymptomatic group. Ten wrestlers (5.1%) had osteophyte formations in the lumbar body; 8 of the 11 osteophytes (72.7%) appeared in the upper lumbar spine. Of the total, 48 wrestlers (24.4%) had deformities (Schmorl nodules) in the lumbar body, and 23 of 50 (46.0%) and 10 of 16 (62.5%) deformities were found in the upper lumbar spine of collegiate and high school wrestlers, respectively. Five wrestlers of the total 197 athletes (2.5%) had disc space narrowing in the lumbar body, with 3 of the 5 cases of disc space narrowing (60.0%) found in the upper lumbar spine. Spondylolysis in the lumbar body was found in 25 wrestlers (12.7%); 19 of the 91 symptomatic wrestlers (20.9%) had spondylolysis, compared with 6 of the 106 (5.7%) asymptomatic wrestlers (P = .0028).
UNASSIGNED: Almost one-third of sumo wrestlers had ≥1 abnormal radiological finding in the lumbar spine. There was a significant relationship between symptomatic wrestlers and spondylolysis.

摘要：
相扑摔跤在日本是一项传统运动，并在世界范围内流行。相扑运动员下背部受伤的危险因素是体重较重和体重指数（BMI）较大。相扑手佩戴的mawashi（腰布带）已被证明可以限制腰椎的运动。
■为了研究相扑对高中和新生大学摔跤手腰椎的影响，调查放射学发现之间的关系，在训练中穿着mawashi,下背部症状。
■案例系列；证据级别，4.
■从2001年到2017年，日本相扑联合会的197名成员（55名高中和142名大学新生）接受了腰椎的常规影像学检查，并回答了有关腰椎症状的问卷。根据对自定义问卷的回答，摔跤手分为有症状和无症状。我们使用非配对t检验来评估患者的人口统计信息，并使用卡方检验来分析有症状和无症状摔跤手之间的影像学腰椎异常。
■摔跤手的平均身高，体重,BMI,运动持续时间为174.0±6.7厘米，107.1±22.4kg,35.2±6.4和8.0±3.2年，分别。有症状组91例（46.2%），无症状组106例（53.8%）。十名摔跤手（5.1％）在腰椎中有骨赘形成；11种骨赘中有8种（72.7％）出现在上腰椎。在总数中，48名摔跤手(24.4%)腰椎畸形(Schmorl结节),在大学和高中摔跤手的上腰椎发现了50例畸形中的23例（46.0％）和16例畸形中的10例（62.5％），分别。总共197名运动员中有5名摔跤手（2.5％）的腰椎椎间盘间隙变窄，5例中有3例椎间盘间隙狭窄(60.0%)见于上腰椎。在25名摔跤手（12.7％）中发现了腰椎滑脱；91名有症状的摔跤手中有19名（20.9％）发生了滑脱，与106名无症状摔跤手中的6名（5.7％）相比（P=.0028）。
■几乎三分之一的相扑摔跤手在腰椎有≥1个异常放射学发现。有症状的摔跤手与脊椎裂之间存在显着关系。
■为了研究相扑对高中和新生大学摔跤手腰椎的影响，调查放射学发现之间的关系，在训练中穿着mawashi,下背部症状。
