An unstraight back may be caused by poor postural habits or organic diseases such as spinal stenosis or fractures, which can be corrected through functional exercises or surgery. 1. Poor postural habits: Poor daily postural habits such as prolonged bowing of the head, working at the desk, and sideways movement can lead to spinal deformities such as kyphosis or lateral curvature, resulting in an unstraightened back. When the degree of deformity is mild, it can be corrected by changing postural habits, functional exercises, wearing a brace to fix it, etc. If the degree of deformity is more serious, it needs to be corrected and fixed by surgery. 2. Organic diseases: If the patient has organic diseases such as spinal stenosis, fracture, etc., the back deformity and not straight, usually corrected by surgery and other reset, and then fixed by plaster or support. If the patient’s back is not straight, he needs to go to the hospital for examination and diagnosis before he can get an effective treatment plan, so as to avoid delaying the condition and affecting the patient’s daily life.
