现在,有许多中小学生背起了双肩背的书包,以避免单肩背书包时由于单肩负重而造成的脊柱变形(也叫脊柱弯曲异常)。但是,有些家长却误以为只要用上双肩背书包,孩子脊柱变形的问题就解决了。其实不然。形成脊柱变形的原因很多,单肩负重只是原因之一。为了弄清楚孩子的脊柱为什么会变形,了解一下脊柱的生理弯曲是有必要的。人的脊柱由二十六块脊椎骨和韧带、肌肉等构成。如果发育正常,从后面看脊柱是笔直的,而从侧面看脊柱则具有向前的颈弯、腰弯和向后的胸
Nowadays, many schoolchildren have shouldered backpacks to avoid spondylolisthesis (also known as abnormal curvature of the spine) caused by shoulder weighting in the shoulder bag. However, some parents mistakenly believe that as long as the use of double shoulder bag, the child’s spine deformation problem is solved. actually not. There are many reasons for the formation of spine deformation, one shoulder weight is only one reason. In order to understand why the child’s spine is deformed, it is necessary to understand the physiological curvature of the spine. The human spine consists of twenty-six vertebrae and ligaments, muscles and the like. If the development is normal, the back of the spine is straight, while the spine from the side has a forward neck bend, lumbar curve and backward chest
