Most patients with lumbar spondylolisthesis are asymptomatic at first, so they do not pay attention to it even if they are unintentionally detected during a physical examination, but over time, they develop symptoms of low back pain and radiating pain and numbness in the lower extremities. There are also some patients with low back pain who do not even know about lumbar spondylolisthesis, so today we will take you to understand what kind of disease it is. What are the symptoms of lumbar spondylolisthesis? Vertebral slippage, also known as degenerative lumbar slippage, refers to a vertebra in the human spine that has slipped in relation to its adjacent vertebrae, and is a lumbar spine polyvalent and common disease. Patients often experience the following symptoms: 1. Restricted activity: the lumbar spine is restricted in its activities, and the pain is often aggravated by forward flexion. Pressure pain at the spinous process of the affected vertebrae can be palpated and the previous spinous process can be moved forward, resulting in the formation of a local step sensation; 2. Intermittent claudication: if the nerve is compressed or combined with lumbar spinal stenosis, intermittent claudication symptoms often occur; 3. Lumbosacral pain: the pain involves the lumbosacral region, mostly dull pain, and very few patients can experience severe caudal pain. The pain may appear gradually after exertion or persist after a single sprain. The pain may be aggravated when standing or bending, and reduced or disappeared after bed rest; 4. Equine caudal nerve involvement or compression symptoms: when the slippage is serious, the involvement of equine caudal nerve may lead to lower limb weakness, saddle area numbness and urinary and fecal dysfunction; 5. Sciatic nerve involvement: the fibrous connective tissue or hyperplastic bone scabs at the isthmus break may compress the nerve root, and the lumbar 5 or sacral 1 nerve root is stretched when slipping, resulting in lower limb radiating pain and numbness The straight leg raise test is mostly positive, and the Kemp’s sign is positive. What are the routine tests required for severe lumbar spondylolisthesis? These are the possible symptoms of lumbar spondylolisthesis, which require timely hospital consultation, while the real diagnosis of lumbar spondylolisthesis in children requires a number of tests, including X-ray, CT and MRI, each of which has a certain purpose; 1. X-ray: including full-length frontal and lateral spine films, which are used to assess the overall balance of the spine and pelvis, and spinal hyperextension and hyperflexion films, which are used to assess the stability of lumbar spondylolisthesis segments; Patients with scoliosis require lateral flexion radiographs; 2. CT examination: to assess changes in the bony structure of the vertebral body, including the morphology of the small joints and isthmus, developmental deformities (cryptoceles, etc.), the degree of bony spinal stenosis, etc.; 3. MRI examination: to more accurately assess the intra-vertebral canal and soft tissue lesions, mainly the degree of spinal stenosis, other developmental deformities, etc.; after suffering from this disease, people not only lumbar spine will have this performance, but also cause symptoms in the legs, such as intermittent claudication, and if the nerve is compressed or combined with lumbar spinal stenosis then intermittent claudication symptoms often occur. The cauda equina nerve is strained or compressed symptoms, and when the slippage is serious, the involvement of the cauda equina nerve may cause symptoms such as weakness of the lower limbs, numbness in the saddle area and dysfunction of urination and defecation. Anterior lumbar convexity increases and hip lordosis. If the above symptoms are found, early medical attention should be sought to avoid delaying the condition.
