Below I will answer from five aspects.
First, it's easy to give away.
Lumbar disc herniation generally occurs between the ages of 20 and 40, and the incidence rate of young adults is about 80%. It is more common in men, and people who are too fat or too thin are prone to lumbar disc herniation. The labor intensity is relatively high, and people who often work at their desks and often stand are more common.
Lumbar muscle strain is common in the following situations: acute lumbar sprain of heavy manual workers will cause lumbar muscle strain if it is not treated in time or handled improperly. Athletes or people who have been engaged in strenuous exercise for a long time cause long-term injury to waist muscles during strenuous exercise. Sitting and studying for a long time, or sitting badly at work, can also form chronic lumbar muscle strain.
Second, low back pain
Low back pain is the first symptom of most patients with lumbar disc herniation, and the incidence rate is about 9 1%. It is characterized by dull pain. Because the outer layer of fibrous ring and posterior longitudinal ligament are stimulated by nucleus pulposus, low back pain is caused by sinus nerve, sometimes accompanied by hip pain.
In contrast, lumbar muscle strain often manifests as back pain or swelling pain, and some of them have tingling or burning sensation. The degree of waist pain is sometimes strong and sometimes weak, and it begins to show intermittent pain, gradually becomes persistent pain, and gradually intensifies. The pain changes with the weather, and it will get worse in cold or rainy days. The pain is deeper, aggravated during exercise and relieved after bed rest.
Third, radiation pain
High lumbar disc herniation (lumbar 2 ~ 3, lumbar 3 ~ 4) can cause femoral neuralgia, but it is rare in clinic, less than 5%. The vast majority of patients are lumbar 4 ~ 5, lumbar 5 ~ sacrum 1, showing sciatica. Typical sciatica is radiation pain from the lower back to the hip, the back of thigh, the outside of calf and the foot, which will be aggravated when the abdominal pressure increases such as sneezing and coughing. Most of the limbs with radiation pain are on one side, and only a few patients with central or paracentral nucleus pulposus protrusion show symptoms of both lower limbs.
Lumbar muscle strain is usually just low back pain, that is, the pain of muscles on both sides of the lower back.
Fourth, the bidding point.
Lumbar disc herniation: Some patients have tenderness in the spinous process or space, and the tenderness point is mainly located beside the spinous process, that is, the middle of the back. When tenderness occurs, radiation pain of lower limbs along nerve roots may occur.
Lumbar dorsal muscle strain: usually there is no tenderness between lumbar spinous processes, but there is tenderness in local areas of lumbar dorsal muscles, mostly at the anchorage point of sacrospinous muscle, iliac spine back, sacrospinous muscle behind sacrum or lumbar transverse process. That is, the muscles on both sides of the back away from the midline of the back.
If the specific location of the pain site is not clear, there is no obvious tenderness point when pressing, which is more likely to be low back pain caused by lumbar intervertebral disc.
Verb (abbreviation for verb) symptoms of ponytail
In patients with lumbar disc herniation, the nucleus pulposus directly behind it or the detached intervertebral disc tissue compresses cauda equina nerve, which is mainly manifested as dysuria and dysuria, and abnormal perineum and perianal sensation. In severe cases, symptoms such as uncontrolled defecation and incomplete paralysis of both lower limbs may occur, which are rare in clinic.
Lumbar muscle strain will not appear the above symptoms.
Written in the back: lumbar disc herniation and lumbar muscle strain are common and frequently-occurring diseases in orthopedics; But there are obvious differences in etiology and treatment between them. Therefore, it is our ultimate goal to make a simple difference between the two in life, to be aware of it, to find it early and to treat it early.
