明确腰椎前凸和骨性关节炎及骨质疏松症的相关性。

该研究为横断设计对照研究，给予2016年1月至2017年1月本院门诊就诊的112例绝经后女性患者骨密度测定及脊柱X线片，腰椎前凸通过Cobb′s角测量法。将患者分为骨质疏松组、骨性关节炎组、骨质疏松＋骨性关节炎组、对照组，并记录所有患者的年龄、身高、体重、身体质量指数、日常活动量、基础代谢率。

4组间身高、体质量指数、日常活动、L1-5、L1-S1、L5-S1比较，差异均无统计学意义（P>0.05）。4组间年龄、体重、BMR（H-B）、BMR（Sch）比较，差异均有统计学意义（P<0.01），其中，与对照组比较，OP组和OP＋OA组的年龄均较高，体重及BMR（H-B）均较小，差异均有统计学意义（P<0.01或P<0.05）；与OA组比较，OP＋OA组的年龄较高，体重及BMR（H-B）较小，差异有统计学意义（P<0.01或P<0.05）。

尽管脊柱骨性关节炎、骨质疏松症有相似的特征，但是腰椎前凸不是其发生的主要原因。腰椎前凸和脊柱骨性关节炎、骨质疏松症没有直接相关性。

To determine whether lumbar lordosis correlates with osteoarthritis (OA) and osteoporosis (OP).

A cross-sectional, blinded, controlled design was implemented. One hundred and twelve postmenopausal women were evaluated for bone mineral density and underwent spinal radiography. Lordosis measurement was performed by Cobb′s method. The participants were divided into four groups: patients with OP, patients with OA, patients with both diseases, and controls. For all participants, age, height, weight, body mass index, physical activity, and basal metabolic rate were measured and recorded.

There were no statistically significant differences in height, body mass index, daily activities, L1-5, L1-S1 and L5-S1 between the four groups (P>0.05). The comparison between the four groups of age, weight and BMR (H-B), BMR (Sch) had statistically significant differences(P<0.01), and compared with control group, the age of the OP group and the OP + OA group had a higher age, a smaller weight and a smaller BMR(H-B), and the differences were statistically significant (P<0.01 or P<0.05); compared with the OA group, OP+ OA group had a higher age, a smaller weight and a smaller BMR(H-B), and the differences were statistically significant (P<0.01 or P<0.05).

Lumbar lordosis does not correlate with OP or OA.
