Description
Technical Field
[0001] The utility model relates to the technical field of spinal examination, in particular to a spinal examination bed. Background Art
[0002] Lumbar spondylolisthesis refers to a disease in which the lumbar vertebrae are partially or completely misaligned. It is generally called spondylolisthesis in clinical practice, and usually the upper vertebra slips forward. It is generally believed that routine X-ray examinations of patients with low back pain have found that about 5% of adults have a tendency to lumbar spondylolisthesis.
[0003] At present, the cause of lumbar spondylolisthesis is still unclear. The most common cause of lumbar spondylolisthesis is degenerative lumbar spondylolisthesis that occurs with age, also known as pseudospondylolisthesis; the second most common cause is lumbar spondylolisthesis caused by sports injuries, congenital or unknown reasons, also known as true spondylolisthesis; lumbar spondylolisthesis often occurs between L4 and L5 vertebrae and between L5 and S1 vertebrae.
[0004] Lumbar spondylolisthesis caused by lumbar isthmic fracture is called true lumbar spondylolisthesis. The cause of isthmic fracture is not very clear at present. It may be related to the narrow and weak isthmus during the development of the lumbar spine. On this basis, the isthmus is prone to fatigue fracture and break, and then the fracture does not heal, resulting in isthmic fracture. It may also be caused by lumbar trauma during adolescence. Some young athletes who often do lumbar extension movements are also prone to lumbar isthmic fracture. The reason may be related to the repeated damaging stimulation of the isthmus during lumbar extension.
[0005] In the prior art, when checking whether there is lumbar spondylolisthesis, X-rays or bi-oblique images of the lumbar spine are generally used. However, when the condition is complicated, such as combined with lumbar disc herniation, lumbar spinal stenosis, or lumbar lesions are excluded, lumbar flexion and extension films should be taken to observe the stability of the slipped vertebral body. In addition, CT, MRI and other examinations are also required to understand the compression of the nerve roots.
[0006] For some experienced doctors, when the patient's spine is bent to a certain angle, a snapping sound will be heard and the doctor can tell by touch whether the patient has lumbar spondylolisthesis. This can save some examination costs during the initial examination. However, in the prior art, most examination beds are flat beds. Doctors let patients lie on their sides on the beds for examination, and the patients need to bend themselves to bend their spines. This is inconvenient to operate, and it is difficult for doctors to control the degree of bending of patients. Utility Model Content
