lumbar muscle strain
Introduction
Introduction to lumbar muscle strain Lumbar muscle strain, also known as functional low back pain, chronic lower back injury, lumbar gluteal muscle fasciitis, etc., is a chronic injury inflammation of the lumbar muscle and its attachment point fascia or periosteum, is one of the common causes of low back pain, the main symptoms It is pain or soreness in the waist or lumbosacral region. It can be repeated and the pain can change with the climate change or the degree of exertion. For example, during the day, the fatigue will be aggravated, and the rest can be relieved when it is light and heavy. It is a common clinical disease, frequently-occurring disease, and disease factors. More. basic knowledge The proportion of illness: 0.12% Susceptible people: no specific population Mode of infection: non-infectious Complications: lumbar disc herniation lumbar spinal stenosis
Cause
Lumbar muscle strain cause
Weight-bearing activities (30%):
When the trunk is under weight-bearing activity, the lower the position, the greater the weight, so the waist is most stressed and concentrated. The stability of the trunk is mainly in the spine. When the spine structure is unstable, the back muscles that assist the stabilization will work overloaded to stabilize the trunk. In the long run, the muscles produce compensatory hypertrophy and hyperplasia.
Poor sitting position (30%):
Long-term bending workers, the waist muscles continue to be in a state of tension, causing small blood vessels to be compressed, insufficient oxygen supply, accumulation of metabolites, stimulating local and forming injurious inflammation. If such a chronic strain occurs in a group of muscles, it will surely produce a corresponding change in the corresponding muscles to compensate for the dysfunction after the lesion at the round point, which is called the corresponding compensation adjustment. If the muscle of the primary lesion remains unable to maintain normal function after corresponding compensation adjustment, the upper, lower or contralateral muscles can be recompensated, which is called series compensation adjustment. The above changes, clinically manifested as a site of low back pain can develop up, down or contralaterally with time. Some patients may also be treated as chronic lumbar muscle strain due to improper treatment of acute lumbar trauma.
Climate and environmental conditions (30%):
Chronic lumbar muscle strain has a certain relationship with climatic and environmental conditions. Too low temperature or too much humidity can promote or aggravate lumbar muscle strain.
Prevention
Lumbar muscle strain prevention
basic method
1. Prevent moisture, cold and cold. Do not sleep in a damp place at will. According to the change of climate, add clothes at any time, after sweating and raining, you should change the wet clothes or dry your body in time. Use electric blankets or sleep hot steamed buns when it's cold.
2, acute lumbar sprain should be actively treated, rest assured to prevent chronic changes.
3. When preparing for sports or strenuous activities, be prepared for activities.
4, correct bad working posture, such as bending over too long, or the case is too low and so on.
5, to prevent overwork, people like a machine, excessive operation or overloaded use, will inevitably lead to damage to certain parts or the entire machine. As the center of human body movement, the waist is overworked, which inevitably causes injury and low back pain. Therefore, pay attention to work and labor in all work or labor.
6, using a hard padded bed, sleep is one of the important parts of people's lives. The suitability of the bed directly affects the health of the person. A soft mattress cannot maintain the normal curvature of the spine, so it is best to add a 10 cm thick cushion to the board.
7, pay attention to weight loss, weight control, the body is too fat, will inevitably bring extra burden to the waist, especially middle-aged people and women postpartum, are easy to gain weight, control diet, strengthen exercise is necessary.
8, temperamental matters, "waist is the house of the kidneys", the frequency of sexual intercourse must be detrimental to the kidney, kidney loss is low back pain.
9, labor, labor posture is not correct, easy to cause lumbar muscle strain. Now list some correct labor postures to help you prevent lumbar muscle strain. When carrying heavy objects, the chest and waist are slightly bent forward, the hips and knees are slightly bent 5, the steps are stable, and the steps are not large.
Complication
Lumbar muscle strain complications Complications lumbar disc herniation lumbar spinal stenosis
If the patient repeatedly attacks lumbar muscle strain or lumbar muscle fasciitis, it is easy to accelerate the degeneration of the lumbar vertebrae. Over time, it may easily cause more serious lumbar disc herniation or lumbar spinal stenosis.
Symptom
Symptoms of lumbar muscle strain Common symptoms Lumbar unstable lock-up phenomenon Lumbar muscle tendon fatigue When the waist is sore or painful Low back pain, excessive back pain, buttocks, soreness, lumbar degeneration, pain, lumbar muscle spasm
1. The waist is sore or painful, partly stinging or burning.
2. Increased when tired, relieved at rest; appropriate activities and frequent changes in position, and excessive activity.
3. Can not insist on bending over, often forced to stretch at all times or hit the waist with a fist to relieve pain.
4. There is tenderness in the waist, mostly in the sacral spine, the posterior tibial spine, the posterior tibial spine muscle or the lumbar vertebrae.
5. There is no abnormality in the shape and movement of the waist, and there is no obvious lumbar muscle spasm. A few patients have limited waist activity.
Examine
Lumbar muscle strain examination
1, X-ray examination: no abnormalities, a small number may have bone hyperplasia or spinal deformity.
2, elderly or osteoporosis patients can choose ECT examination, bone density examination, there is a view that osteoporosis can also cause chronic low back pain.
Diagnosis
Diagnosis and diagnosis of lumbar muscle strain
Diagnose based on
1. The range of tenderness in the lower back is wider. The tender points are mostly in the sacral spine, the transverse process of the lumbar vertebrae and the posterior margin of the palate.
2, tendon: lumbar muscle tension when palpation, or induration and hypertrophy.
3, X-ray examination: a small number of patients may have congenital malformations and bone hyperplasia in elderly patients, no abnormal findings.
Differential diagnosis
It is differentiated from lumbar protrusion.
