Abstract

Purpose: This study examined the predictive value of the gluteal muscle index (GMI) for diagnosing sarcopenia in patients with degenerative lumbar disease (DLD), highlighting the need for effective diagnostic markers in this population.

Methods: This prospective observational study included 202 elderly patients scheduled for lumbar spine surgery. Muscle indices for psoas, paraspinal, and gluteal muscles were measured using multiaxial computed tomography. Sarcopenia was diagnosed per the 2019 Asian Working Group for Sarcopenia (AWGS) criteria. Statistical analysis comprised univariate and multivariate logistic regression to identify predictors of sarcopenia.

Results: Of patients, 77% were diagnosed with sarcopenia. The GMI and psoas muscle index (PMI) were identified as significant predictors of sarcopenia in the univariate analysis. Multivariate analysis confirmed their predictive value, with higher indices correlating with a reduced risk of sarcopenia (GMI odds ratio [OR] = 0.95, 95% confidence interval [CI] = 0.92-0.97; PMI OR = 0.95, 95% CI = 0.92-0.98, both P < .001).

Conclusion: The GMI serves as a reliable predictor of sarcopenia in elderly patients undergoing lumbar spine surgery for DLD, suggesting a significant role of gluteal muscles in diagnosing sarcopenia. Incorporating GMI into clinical assessments is critical to better manage and diagnose sarcopenia in this population.

多轴 CT 扫描显示的臀肌横截面积是诊断腰椎退行性疾病患者肌肉疏松症的预测指标。

目的：本研究探讨了臀部肌肉指数（GMI）对诊断退行性腰椎病（DLD）患者肌少症的预测价值，强调了该人群对有效诊断指标的需求：这项前瞻性观察研究纳入了 202 名计划接受腰椎手术的老年患者。使用多轴计算机断层扫描测量了腰肌、脊柱旁肌和臀肌的肌肉指数。根据 2019 年亚洲肌肉疏松症工作组（AWGS）标准诊断肌肉疏松症。统计分析包括单变量和多变量逻辑回归，以确定肌少症的预测因素：结果：77%的患者被诊断为肌肉疏松症。在单变量分析中，GMI 和腰肌指数 (PMI) 被确定为肌少症的重要预测指标。多变量分析证实了它们的预测价值，指数越高，患肌肉疏松症的风险越低（GMI 比值比 [OR] = 0.95，95% 置信区间 [CI] = 0.92-0.97；PMI 比值比 [OR] = 0.95，95% 置信区间 [CI] = 0.92-0.98，均为 P 结论：GMI 是预测因 DLD 而接受腰椎手术的老年患者肌肉疏松症的可靠指标，这表明臀肌在诊断肌肉疏松症中发挥着重要作用。将 GMI 纳入临床评估对于更好地管理和诊断这类人群的肌肉疏松症至关重要。

期刊介绍： "European Spine Journal" is a publication founded in response to the increasing trend toward specialization in spinal surgery and spinal pathology in general. The Journal is devoted to all spine related disciplines, including functional and surgical anatomy of the spine, biomechanics and pathophysiology, diagnostic procedures, and neurology, surgery and outcomes. The aim of "European Spine Journal" is to support the further development of highly innovative spine treatments including but not restricted to surgery and to provide an integrated and balanced view of diagnostic, research and treatment procedures as well as outcomes that will enhance effective collaboration among specialists worldwide. The “European Spine Journal” also participates in education by means of videos, interactive meetings and the endorsement of educative efforts.
