This study investigated the impact of post-traumatic kyphosis (PTK) on the lumbar spine using a local Cobb angle of 30° as the cutoff point. The measurements included the local Cobb angle, lumbar lordosis angle (L1-L5), intervertebral space angle (IVSA), lumbar disc degeneration, and posterior wall height loss (PWHL). Patient characteristics such as sex, age, disease duration, American Spinal Injury Association (ASIA) grade, fracture site, bone mineral density (BMD), Oswestry Disability Index (ODI), and visual analogue scale (VAS) score were also recorded. Patients were divided into two groups based on the thoracolumbar local Cobb angle: Group 1 (local Cobb angle > 30°, n = 48) and Group 2 (local Cobb angle ≤ 30°, n = 28). Comparative analysis revealed that Group 1 had a significantly longer disease duration, higher VAS and ODI scores, greater lumbar lordosis angle, increased L4/5 IVSA, and more severe lumbar disc degeneration (p < 0.05). Furthermore, across all patients, disease duration, lumbar lordosis angle, and L4/5 IVSA were positively correlated with the local Cobb angle (p < 0.05). These findings suggest that when the local Cobb angle exceeds 30°, PTK may aggravate lumbar degeneration.
本研究以30°的局部Cobb角作为截断点，调查创伤后脊柱后凸（PTK）对腰椎的影响。测量指标包括局部Cobb角、腰椎前凸角（L1-L5）、椎间隙角（IVSA）、腰椎间盘退变和后壁高度丢失（PWHL）。还记录了患者的特征，如性别、年龄、病程、美国脊髓损伤协会（ASIA）分级、骨折部位、骨密度（BMD）、Oswestry功能障碍指数（ODI）和视觉模拟量表（VAS）评分。根据胸腰椎局部Cobb角将患者分为两组：第1组（局部Cobb角>30°，n = 48）和第2组（局部Cobb角≤30°，n = 28）。比较分析显示，第1组的病程明显更长，VAS和ODI评分更高，腰椎前凸角更大，L4/5 IVSA增加，腰椎间盘退变更严重（p < 0.05）。此外，在所有患者中，病程、腰椎前凸角和L4/5 IVSA与局部Cobb角呈正相关（p < 0.05）。这些发现表明，当局部Cobb角超过30°时，PTK可能会加重腰椎退变。
