There is a lack of studies on obesity measured by outer abdominal fat (OAF), which describes abdominal subcutaneous adipose tissue thickness with regard to spino-pelvic parameters. We investigated OAF and its physiologic values on computed tomography (CT) scans with regard to age, gender, facet joint (FJ) arthritis, FJ orientation, lumbar lordosis (LL) and pelvic incidence (PI).
OAF, lumbar FJs, LL and PI were evaluated on CT scans.
CT scans of 620 individuals with a mean age of 42.5 years were reviewed. OAF showed a mean value of 19.7 millimeters (mm). It significantly increased with age until 70 years and decreased thereafter (p 0.0001). There was no significant gender difference. OAF was significantly increased with FJ arthritis (p = 0.01), but not with FJ orientation, LL or PI.
OAF on CT scans seems to have a mean value of 19.7 mm. It is higher in the older age groups until 70 years and declines again afterward. As a novelty finding, OAF significantly increases with higher degrees of FJ arthritis, but is not related to gender or other spino-pelvic parameters such as FJ orientation, LL or PI. Differences in fat distribution may be found at other anatomic sites, such as visceral fat. Obese patients may benefit from weight loss by decreasing their FJ arthritis, which may potentially decrease associated back pain, which may be worth further investigations.
目前缺乏关于通过腹部外周脂肪（OAF）测量肥胖的研究，OAF描述了腹部皮下脂肪组织厚度与脊柱骨盆参数的关系。我们在计算机断层扫描（CT）上研究了OAF及其生理值与年龄、性别、小关节（FJ）关节炎、FJ方向、腰椎前凸（LL）和骨盆入射角（PI）的关系。
在CT扫描上评估OAF、腰椎FJ、LL和PI。
回顾了620名平均年龄为42.5岁个体的CT扫描结果。OAF的平均值为19.7毫米（mm）。在70岁之前，OAF随年龄显著增加，此后下降（p<0.0001）。性别之间无显著差异。OAF在FJ关节炎患者中显著增加（p = 0.01），但与FJ方向、LL或PI无关。
CT扫描上的OAF平均值似乎为19.7mm。在70岁之前的老年人群中较高，之后再次下降。作为一个新发现，OAF随FJ关节炎程度的增加而显著增加，但与性别或其他脊柱骨盆参数如FJ方向、LL或PI无关。在其他解剖部位如内脏脂肪可能存在脂肪分布差异。肥胖患者通过减轻FJ关节炎可能会受益于体重减轻，这可能会潜在地减轻相关的背痛，这值得进一步研究。
