摘要

背景:腰椎峡部裂是一种常见于青少年运动员,尤其是棒球运动员的腰椎弓应力性骨折。腰椎前凸角(LLA)的增加会增加椎弓上的压缩应力,影响LS的发展。然而,LLA对青少年棒球运动员LS发展的影响尚不清楚。因此,有必要阐明影响LS发展的危险因素。本横断面研究旨在调查LLA对青少年棒球运动员LS发展的影响。方法:患者为11-18岁的男性棒球运动员,他们在2018年1月1日至2021年10月31日期间以腰椎疼痛为主要主诉前往骨科诊所,并接受了核磁共振成像(MRI)检查。LLA定义为由平行于L1和S1的上终板的线形成的角度。数据分析师以外的其他人从MRI中测量了三次LLA,平均值用于数据分析。进行Logistic回归分析,以LS的存在或不存在为目标变量,LLA、年龄和以前的投球经验为解释变量。结果:在纳入的112名受试者中,LS组79名,非LS组33名。LS组的LLA为45.42±8.19°,非LS组为36.68±8.26°,两组之间存在显著差异。逻辑回归分析显示,即使在调整了年龄和以前的投球经验后,LLA也存在显著差异,优势比为1.140(95%置信区间:1.070-1.21)。结论:LS组青少年棒球运动员的LLA明显高于非LS组,这可能影响LS的发展。

Effect of lumbar lordosis angle on the development of lumbar spondylolysis in adolescent baseball players: A cross-sectional study

Background

Lumbar spondylolysis (LS) is a lumbar vertebral arch stress fracture that often occurs in adolescent athletes, especially baseball players. An increase in lumbar lordosis angle (LLA) increases the compressive stress on the vertebral arch, influencing the development of LS. However, the effect of LLA on LS development in adolescent baseball players is unknown. Therefore, it is necessary to elucidate the risk factors that influence the development of LS. This cross-sectional study aimed investigate the effect of LLA on LS development in adolescent baseball players.

Methods

Patients were male baseball players aged 11–18 years who visited an orthopedic clinic with a chief complaint of lumbar pain and underwent a magnetic resonance imaging (MRI) examination between January 1, 2018, and October 31, 2021. LLA was defined as the angle formed by the line parallel to the superior endplate of the L1 and S1. A person other than the data analyst measured LLA three times from the MRI, and the average value was used for data analysis. Logistic regression analysis was performed, with the presence or absence of LS as the objective variable and LLA, age, and previous pitching experience as explanatory variables.

Results

Of the 112 subjects included, 79 were in the LS group and 33 in the non-LS group. The LLA was 45.42 ± 8.19° in the LS group and 36.68 ± 8.26° in the non-LS group, with significant differences between the groups. Logistic regression analysis showed that LLA significantly differed with an odds ratio of 1.140 (95% confidence interval: 1.070–1.21), even after adjusting for age and previous pitching experience.

Conclusions

LLA in adolescent baseball players was significantly greater in the LS group than in the non-LS group, which may influence the development of LS.
