Chronic back strain

Introduction to chronic waist strain Lumbar muscle strain is a chronic injury to the lumbar muscle and its attachment fascia, or even periosteum, which is a common cause of low back pain. Frequent repeated accumulation of minor damage (strain) can cause pathological changes such as congestion, edema, exudation, fibrous tissue hyperplasia and adhesion of muscle attachment points, periosteum, ligaments, etc., and stimulate and compress nerve endings to cause low back pain. basic knowledge The proportion of sickness: 0.5% (more common in heavy physical labor, the incidence rate is about 0.5%) Susceptible people: no special people Mode of infection: non-infectious Complications: muscle atrophy

Causes of chronic strain of the waist

Strain (95%):

Frequent repeated accumulation of minor damage (strain), can cause muscle adhesion, periosteum, ligament and other tissue congestion, edema, exudation, fibrous tissue hyperplasia and adhesions and other pathological changes, stimulation and compression of nerve endings lead to low back pain, lesions occur Later, in order to reduce the activity of the lesion, some muscles are often paralyzed, and persistent lumbar tendon can also cause accumulated strain of soft tissue, which aggravates the pathological changes of the tissue, and some occupations need to work in a fixed posture. It is also an important cause of strain. If the acute soft tissue sprain fails to recover completely, it may turn into chronic strain.

Chronic strain prevention at the waist

1, in order to prevent the occurrence of lumbar muscle strain, first of all should maintain a good posture, the correct posture should be head-up, abdomen, chest, maintain the normal curvature of the spine, especially for school-age children to maintain a good posture is most important, It is also necessary to strengthen physical exercise, so that the waist muscles, ligaments, and joint capsules are in a good state of healthy development, the waist muscles are strong, the ligaments are elastic, and the chance of lumbar muscle strain is greatly reduced.

2, should pay attention to body position in normal labor or work, should try to avoid long hours of work and labor in a bad position, people in a single labor posture should adhere to the exercise, or use the waist to protect the waist; for chronic diseases, Malnourished, obese people should pay more attention to work and rest, do more rest, should not be overworked; after acute acute sprain injury should be thoroughly treated in time and pay attention to the waist to keep warm, to avoid cold at the waist.

Lumbar chronic strain complications Complications muscle atrophy

Patients with this disease develop pain and protective tendon due to muscle imbalance in the lower back, and a series of pathological changes occur. For example, muscle weakness can not maintain the normal lumbar functional position, which causes the deep ligament to be involved; the peripheral nerves and blood vessels in the muscle are squeezed and circulated. Insufficient, metabolite accumulation and inflammatory substances, and then form new pain points, and even lead to muscle atrophy, contracture, degeneration, adhesion and tissue fibrosis; one side ligament and soft tissue shortening and other side relaxation, balance imbalance, pain spread The autonomic nervous system disorder, involving the upper limbs, also has a series of compensatory symptoms.

Symptoms of chronic strain at the waist Common symptoms After lumbar exercise, low back pain, low back pain, soft waist, can not straight up the side of the abdominal wall or the back of the lower back has tender muscle induration, the third lumbar vertebrae...

Most of the strains are chronic, and there is no clear history of acute trauma; some patients have a history of heavy physical labor, strenuous exercise or trauma; some patients have poor posture or have long bent over. Symptoms are light and heavy, generally improve after a break, increase after exertion, can not sit for a long time, must change position frequently. Some patients have different degrees of tenderness in the interspinous, posterior iliac spine, ankle or lumbosacral joints, and at the second and third transverse processes of the lumbar vertebrae. Some patients have a wide range of tenderness or no fixed tenderness. X-ray examination generally has no abnormal findings.

Examination of chronic strain of the waist

The main points and methods of examination of this disease are as follows:

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.

Diagnosis and differentiation of chronic liver strain

The disease needs to be differentiated from sciatica. The lumbar muscle strain has a long history of low back pain, repeated attacks, and the side or both sides of the lumbosacral region are sore and uncomfortable. When it is light and heavy, it is not lingering. According to different parts of the strain, there may be Extensive tenderness, but generally not obvious, its soreness is exacerbated after exertion, relieved after rest, and is associated with climate change.
