【摘要】：分析比较下腰椎各节段椎间盘退变程度与脊柱-骨盆矢状面各平衡参数间的关系。选取符合选择标准的130例腰椎退行性疾病患者均拍摄脊柱全长X线片以及腰椎MR,依据Pfirrmann分级评定病变节段椎间盘的退变程度;利用院内影像归档与通信系统(PACS)测量以下矢状面参数:矢状面躯干位移(SVA)、腰椎前凸角(LL)、胸椎后凸角(TK)、骨盆倾斜角(PT)、骨盆入射角(PI)、骶骨倾斜角(SS)。将所有患者按PI测量值分为小于正常范围组(A组)、正常范围组(B组)和大于正常范围组(C组),分节段比较各组椎间盘退变程度;以矢状面平衡各参数的测量数值与椎间盘退变等级为依据进行分组,比较各节段椎间盘退变等级与矢状面平衡参数间的关系。L_5~S_1椎间盘退变对脊柱-骨盆整体参数具有重要影响,是导致躯干失衡的重要因素。大于正常范围的PI可导致或加重L_5~S_1节段椎间盘的退变;PT及PI与下腰椎椎间盘退变程度显著相关。
[Abstract]:Comparison of segmental lumbar disc degeneration and the spine pelvis sagittal balance of the relationship between the parameters. A total of 130 patients with lumbar degenerative disease were taken according to the selection criteria of total spine X-ray and MR lumbar degeneration, according to the Pfirrmann grading lesions of intervertebral disc; use the hospital image archiving and communication system (PACS) to measure the following parameters: the sagittal sagittal trunk shift (SVA), lumbar lordosis (LL), thoracic kyphosis (TK), pelvic tilt (PT), pelvic incidence (PI), sacral slope (SS). All patients were measured by PI value is less than the normal group (A group), normal group (group B) and more than the normal group (C group), comparison of segmental disc degeneration; parameters of the sagittal balance of the measured value and the intervertebral disc degeneration grade were grouped according to the comparison, each segment disc degeneration The relationship between.L_5~S_1 intervertebral disc degeneration grade and sagittal balance between parameters has important influence on the whole spino pelvic parameters is an important factor leading to trunk imbalance. More than the normal range of PI can cause or aggravate L_5~S_1 segment of intervertebral disc degeneration; PT and PI were significantly correlated with a lower lumbar intervertebral disc degeneration.
