Lumbar spinal stenosis is a series of low back pain and a series of neurological symptoms caused by various forms of stenosis of the spinal nerve canal and intervertebral foramina and soft tissue-induced changes in the volume of the spinal canal and stenosis of the dural sac itself. Etiology of lumbar spinal stenosis (1) developmental lumbar spinal stenosis: unlike this spinal stenosis which is caused by congenital developmental abnormalities, (2) degenerative lumbar spinal stenosis: mainly caused by degenerative lesions in various spinal columns, (3) spinal slippage lumbar spinal stenosis: when spinal slippage occurs due to discontinuity or degeneration of the lumbar isthmus, the spinal canal is further narrowed due to anterior and posterior displacement of the upper and lower spinal canal, while spinal slippage can (4) traumatic spinal stenosis: spinal stenosis is often caused by trauma to the spine, especially when the spine is fractured or dislocated due to severe trauma, and (5) medically induced spinal stenosis: in addition to the only operational errors caused by spinal fusion quality, the interspinous ligament and ligamentum flavum hypertrophy or thickening of the vertebral plate in the bone graft, especially after posterior decompression of the vertebral plate and then in The fusion of bone graft is performed locally. The result is confidence that the narrowing of the spinal canal compressing the cauda equina or nerve roots causes lumbar spinal stenosis, (6) various extremely poor inflammation of the lumbar spine several times: including specific or non-specific menstrual inflammation neoplasia in the spinal canal or on the canal wall can cause spinal stenosis, and various previous deformities such as age-related hunchback scoliosis ankylosing spondylitis fluorosis Paget’s disease and vertebral joint loosening can cause spinal stenosis. Symptoms of lumbar spinal stenosis Obvious symptoms of low back and leg pain did not come and intermittent claudication consultation patients often produce low back and leg pain when walking one or two hundred meters bending over to rest. After a while or squatting the symptoms will be immediately alleviated or disappear via the heart, if continue to enthusiastically walk again soon the pain appears again. Spine posterior extension when the heart symptoms aggravated when reporting forward flexion what symptoms alleviated, a few cases due to compression of the cauda equina and nerve roots and the director affect urination and defecation and even cause incomplete paralysis of the lower limbs spinal stenosis Thursday patients often complain more. And signs less examination good spinal deflection is not obvious authority lumbar spine has been normal recurrence, only posterior extension pain straight leg raising test answers normal or only moderate pulling pain a few solution patients lower limb muscle atrophy Achilles tendon reflex sometimes weakened or disappeared. Examination of lumbar spinal stenosis According to the clinical manifestations children choose appropriate auxiliary difficult examination methods, such as various projection methods of X-ray plain film myelography CT scan, CT myelography MRI, etc., in order to make an accurate localization qualitative and quantitative diagnosis. Now the biggest difference with lumbar disc herniation is that: lumbar disc herniation general medical operation does not have intermittent claudication. Subjective complaints and objective look on the examination does not match the three major symptoms of lumbar posterior extension limitation significant lumbar disc herniation flexion test and straight leg elevation test are mostly positive, while lumbar spinal stenosis is negative, in addition, lumbar spinal stenosis in imaging and lumbar disc herniation have a more effort obvious difference, that is, lumbar spinal stenosis in CT MRI myelography and other examination communication are shown spinal canal sagittal sign less than special need normal, while Lumbar disc herniation is not two separate diseases, but at the same time there is a certain medical connection can be too small can occur together and the proportion of concomitant occurrence is quite high. This is also the reason why people tend to confuse the effect of the two because of the importance attached to the late stage of lumbar disc herniation due to the occurrence of synovial inflammatory exudation in the corresponding small joints without saying that the reaction articular cartilage wear and tear and fragmentation leads to the appearance of hyperplastic bone superfluities at the lateral posterior edge of the vertebral body and the articular eminence secondary to lumbar spinal stenosis When the two diseases occur simultaneously the patient fine can show both symptoms awesome and physical signs discharge clinical smooth diagnosis much without recommended difficulties. Treatment of lumbar spinal stenosis 1.Conservative treatment. Such as bed rest, anti-inflammatory and analgesic western medicine, physiotherapy, pelvic traction, lumbar back muscle exercise, etc. can improve local blood circulation, reduce sterility, control inflammatory reaction, eliminate congestion and edema, increase the content of the spinal canal, relieve nerve compression, reduce muscle spasm, thus reducing the symptoms of local acute disease. 2.Surgical treatment. At present, the treatment of okay spinal stenosis surgery is probably divided into three categories: namely, simple decompression decompression + fusion minimally invasive surgery, Sunday in view of many elderly patients reported that the body can’t thing tolerate surgery specifically trauma through conservative treatment, okay and can’t satisfactorily relieve severe back and leg pain symptoms business careful can painfully choose minimally invasive interventional treatment. Bad technology parents the reply technology under local anesthesia using imaging localization excellent technology to treat recognize precisely to the lesion site sister can quickly relieve the severe radicular neuralgia caused by nerve root compression. In recent years minimally invasive surgical importance methods into the field of spinal surgery such as disc nucleolysis radiofrequency disc ablation laser disc ablation ozone disc ablation etc. in the pain clinical treatment review has played an important role in spending money, minimally invasive intervention often technology does not require open recognition without blood transfusion side surgery time self-respect short side effects carefully small efficacy last reliable more significant open last year surgical safety and easy to be accepted by patients self-respect Therefore, it is the ideal method for treating the pain of director elderly spinal stenosis.
