BACKGROUND
Magnetic resonance imaging (MRI) studies have shown that gymnasts have a high prevalence of radiological abnormalities, such as intervertebral disk degeneration (IDD) and anterior limbus vertebra (ALV). These 2 abnormalities may coexist at the same spinal level. However, the relationship between IDD and ALV remains unclear.
HYPOTHESIS
A significant relationship exists between IDD and ALV in Japanese collegiate gymnasts.
STUDY DESIGN
Case-control study.
METHODS
A total of 104 Japanese collegiate gymnasts (70 men and 34 women; age, 19.7 ± 1.0 years) with 11.8 ± 3.6 years of sporting experience participated. T1- and T2-weighted MRIs were used to evaluate ALV and IDD.
RESULTS
The prevalence among the gymnasts of IDD and ALV was 40.4% (42/104) and 20.2% (21/104), respectively. The prevalence of IDD was significantly higher in gymnasts with ALV than those without ALV, as determined using the chi-square test. Logistic regression analysis demonstrated a significant association between IDD and ALV (adjusted odds ratio [OR], 6.60; 95% confidence interval [CI], 2.14-20.35). IDD was further grouped by whether it was present in the upper lumbar region (L1-2, L2-3, and L3-4 disks) or in the lower lumbar region (L4-5 and L5-S1 disks). Upper IDD had a greater association with ALV (adjusted OR, 33.17; 95% CI, 7.09-155.25) than did lower IDD (adjusted OR, 6.71; 95% CI, 1.57-28.73).
CONCLUSION
In Japanese collegiate gymnasts, ALV is a predictor of IDD, especially in the upper lumbar region.
CLINICAL RELEVANCE
Information regarding ALV is important to prevent IDD in Japanese collegiate gymnasts.
背景
磁共振成像（MRI）研究表明，体操运动员的影像学异常发生率较高，如椎间盘退变（IDD）和前弓状缘椎体（ALV）。这两种异常可能在同一脊柱水平共存。然而，IDD 和 ALV 之间的关系尚不清楚。
假设
日本大学生体操运动员中存在 IDD 和 ALV 之间的显著关系。
研究设计
病例对照研究。
方法
共有 104 名日本大学生体操运动员（70 名男性和 34 名女性；年龄 19.7 ± 1.0 岁），运动经验 11.8 ± 3.6 年。使用 T1 和 T2 加权 MRI 评估 ALV 和 IDD。
结果
体操运动员中 IDD 和 ALV 的患病率分别为 40.4%（42/104）和 20.2%（21/104）。卡方检验显示，患有 ALV 的体操运动员 IDD 的患病率明显高于没有 ALV 的运动员。Logistic 回归分析显示 IDD 和 ALV 之间存在显著关联（调整后的优势比[OR]，6.60；95%置信区间[CI]，2.14-20.35）。进一步将 IDD 分为上腰椎区（L1-2、L2-3 和 L3-4 椎间盘）和下腰椎区（L4-5 和 L5-S1 椎间盘）。上腰椎 IDD 与 ALV 的关联更大（调整后的 OR，33.17；95%CI，7.09-155.25），而下腰椎 IDD 与 ALV 的关联较小（调整后的 OR，6.71；95%CI，1.57-28.73）。
结论
在日本大学生体操运动员中，ALV 是 IDD 的预测因子，尤其是在上腰椎区。
临床相关性
了解 ALV 信息对于预防日本大学生体操运动员的 IDD 很重要。
