两组均为120名志愿者和120名腰痛（LBP）患者，年龄在20-79岁之间，对胸椎和腰椎进行了前瞻性椎体x线摄影分析，以比较几种对脊柱手术计划有用的x线摄影参数。测量以下x线参数：胸后凸、腰椎前凸、骶骨倾斜度、远端前凸（L4-S1）、每个椎体从T4-S1的倾斜度以及相邻椎体之间的相对椎体倾斜度。对照组胸椎后凸随年龄增加（p < 0.0001），骶骨倾斜度随年龄减少（p < 0.05）。对照组术后第60年胸后凸增加与腰椎前凸减少相关（p < 0.01），腰痛组相关性较低（p < 0.05）。与对照组相比，腰痛组胸椎后凸增加较多，但仅在第60年出现（p < 0.01）。与腰痛组相比，对照组腰椎前凸增加更多，但只有在第60年才显著增加（p < 0.001）。LBP患者L5-S1节段前凸明显多于对照组（p < 0.001）。在两组中，腰椎前凸与骶骨倾斜密切相关（p < 0.0001），在对照组中，尤其是在第60年（p < 0.001）。女性受试者的骶骨倾斜度明显高于男性受试者（p < 0.05）。前凸远端（L4-S1）分别占对照组和腰背部患者腰椎前凸总量的55%和49%。脊柱外科医生经常处理矢状面脊柱畸形，矢状面脊柱弯曲和椎体在矢状面倾斜的偏差，无论是正常人还是腰痛患者，都应该在临床上有所帮助。
Two homogenous groups of 120 volunteers and 120 low back pain (LBP) patients, age range 20-79 years, underwent a prospective roentgenographic segmental vertebral analysis of the thoracic and lumbar spine to compare several roentgenographic parameters useful for planning spine surgery. The following roentgenographic parameters were measured: thoracic kyphosis, lumbar lordosis, sacral inclination, distal lordosis (L4-S1), inclination of each vertebra from T4-S1, and relative vertebral inclination between adjacent vertebrae. Thoracic kyphosis increased (p < 0.0001) and sacral inclination decreased (p < 0.05) with age in the control group. Increased thoracic kyphosis correlated with decreased lumbar lordosis after the sixth decade in the control group (p < 0.01), less so in the LBP group (p < 0.05). Increased thoracic kyphosis was seen more in the LBP group than in the controls, but significantly solely in the sixth decade (p < 0.01). Lumbar lordosis was more increased in the controls than in the LBP group but significantly solely in the sixth decade (p < 0.001). The L5-S1 segmental lordosis was much more in the LBP patients than in the controls (p < 0.001). Lumbar lordosis was strongly correlated with sacral inclination in both groups (p < 0.0001) and it was significantly greater in the controls, particularly in the sixth decade (p < 0.001). Sacral inclination was significantly more in the female than in male volunteers (p < 0.05). Distal lordosis (L4-S1) represents 55% and 49% of total lumbar lordosis in controls and low back patients, respectively. Spine surgeons frequently deal with sagittal spinal deformities and the deviations of sagittal spinal curvatures and vertebral inclination in the sagittal plane, both in normal subjects and LBP patients should be clinically helpful.
