Lumbar spondylosis is a relatively common orthopedic disease in our life. So what are the common symptoms of this disease? Here are a few common features of lumbar spondylosis for your reference. Sciatic nerve tenderness Along the path of the sciatic nerve, there can be tenderness from the buttocks to the naevus at the back of the posterior thigh, below the front of the fibular head to the back of the inner and outer ankles, etc. The cause is the medulla of the intervertebral discs. The reason is that the nucleus pulposus of the intervertebral disc presses on the nerve root, and the sciatic nerve becomes more sensitive, sometimes pressing on the relevant branch of the sciatic nerve can also cause pain. When lumbar disc herniation occurs acutely, the paraspinal muscles are tense, which can cause stiff gait, forward leaning, forward flexion of 10°-20° and different degrees of lateral position; lumbar muscle spasm with the affected side of the pelvis shifted upward and the lower limbs in a slightly flexed position, often with the toes of the feet on the ground, using the hands to support the hips, claudication, etc. These signs are a kind of protective reaction. These signs are a protective response to avoid sciatic nerve tension. Restriction of spinal movement More than 90% of patients have different degrees of limitation of lumbar activities, the more obvious one is limitation of forward bending. This is because lumbar activities, such as standing, walking, bending or weight bearing, can increase the pressure on the intervertebral discs and aggravate the results of low back pain. Pressure points in the lumbar region Most patients with significant clinical symptoms have significant pressure points at the rupture of the annulus fibrosus. After heavy pressure, it may radiate along the sciatic nerve to the lower extremities. The proportion of signs with a significant pressure point is about 80%. This is relevant for diagnosis and localization. Spinal deviation This is one of the characteristic signs of lumbar disc herniation. The reason for this is that the physiologic anterior protrusion of the lumbar spine is reduced or absent in most patients. Scoliosis arises as a protective response that still aims to reduce nerve root compression and tension.
