Normative values of sagittal alignment are used as references for the diagnosis and treatment of spinal pathologies. There are currently no reference values for the normative sagittal alignment of Lebanese subjects. The objective is to describe normative values of full body sagittal alignment parameters in asymptomatic Lebanese adults and to compare the sagittal alignment of this population to that of populations of various origins.
Included subjects were aged 18 to 28 years old. Each subject underwent a full body biplanar X-ray exam with measurement of spine, pelvis and lower limb parameters of sagittal alignment. The sagittal alignment of the Lebanese population was compared to that of other ethnicities, previously reported in the literature, using one-way ANOVA.
Ninety-two asymptomatic Lebanese young adult volunteers (48 males, 44 females, age=21.5±2.2 years) were enrolled in this study. The mean curvature in the cervical spine was kyphotic (-4.3°) in women, while it was lordotic in men (5.4°). Men were found to be significantly more kyphotic than women (-58.3° vs. -53.0°; p<0.01) but both sexes were found to have similar lordosis (61.6°) and pelvic incidence (52.0°). Lebanese subjects had intermediate pelvic incidence compared to other ethnicities but showed significantly higher thoracic kyphosis (p<0.01) and lumbar lordosis (p<0.01) compared to all other ethnicities.
This study established reference normative values for young adult Lebanese subjects. Most women were found to have kyphotic cervical spines. The sagittal alignment of Lebanese subjects differed significantly compared to that of other ethnicities.
Level IV - cross sectional study.
矢状面排列的正常值被用作诊断和治疗脊柱病变的参考。目前还没有黎巴嫩受试者正常矢状面排列的参考值。目的是描述无症状黎巴嫩成年人全身矢状面排列参数的正常值，并将该人群的矢状面排列与其他来源人群的矢状面排列进行比较。
纳入的受试者年龄在 18 至 28 岁之间。每位受试者均接受全身双平面 X 射线检查，测量脊柱、骨盆和下肢矢状面排列参数。使用单因素方差分析将黎巴嫩人群的矢状面排列与文献中先前报道的其他种族进行比较。
本研究共纳入 92 名无症状黎巴嫩年轻成年志愿者（48 名男性，44 名女性，年龄=21.5±2.2 岁）。女性颈椎曲率呈后凸（-4.3°），而男性呈前凸（5.4°）。男性明显比女性更后凸（-58.3° vs. -53.0°；p<0.01），但男女的前凸（61.6°）和骨盆入射角（52.0°）相似。与其他种族相比，黎巴嫩受试者的骨盆入射角处于中间水平，但与所有其他种族相比，他们的胸椎后凸（p<0.01）和腰椎前凸（p<0.01）明显更高。
本研究为年轻的黎巴嫩受试者建立了参考正常值。大多数女性颈椎呈后凸。与其他种族相比，黎巴嫩受试者的矢状面排列有显著差异。
