Lumbar muscle strain is one of the common causes of low back pain. It is a chronic injury inflammation of the lumbar muscles and their attachment points of fascia or even periosteum, and is a common low back pain disorder.
Causes
1.As a result of acute lumbar sprain, without timely and reasonable treatment, chronic traumatic scars and adhesions are formed, and the strength of lumbar muscle is weakened and painful.
2, from long-term accumulative trauma, most patients with occupational posture (such as: long-term sitting work, often in non-physiological position under the operation of the repairer, fixed posture workers, repair watches, typing and bending workers). Potential, cumulative tissue damage is formed over time.
Pathology
Lumbar muscle dysfunction, the formation of pain and protective muscle spasm, muscle hypertrophy, compensatory hyperplasia, long-term muscle tension and contracture, so that small blood vessel compression, peripheral nerve compression, insufficient circulation, insufficient oxygen supply, compensation products can not be discharged in a timely manner, and the formation of irritation, resulting in new injury inflammation, and even lead to further muscle atrophy, contracture, degeneration, adhesions and tissue fibrosis. In order to achieve stability of the spine and balance of muscle strength, correspondence compensatory adjustment and series of compensatory adjustments occur, new painful points intertwine, and the condition expands and worsens.
Clinical manifestations
1. Chronic pain without obvious causes is the main symptom, usually soreness and pain, which can be relieved after rest, recoil from bed for too long (morning pain), alleviate after activity, and worsen after too long activity.
2, has a fixed pressure point, mostly located in the starting and ending point of the muscle, neuromuscular combination point, pain point massage percussion, back pain can be reduced instead.
3.Sacral spasm.
4.The spine may have posterior protrusion and lateral protrusion deformity.
5.Recent history of overexertion injury related to low back pain exists. Posture-related occupations.
Differential diagnosis
1, myofascial fibrositis of the lumbar region: widespread pain in the lumbar region with no obvious pressure points and slightly high myotonic forces.
2. Transverse process syndrome of the third lumbar vertebra: symptoms resulting from friction with nearby soft tissues during lumbar activities due to the exceptionally long transverse process of the third lumbar vertebra, after stretching and compressive stimulation. Local pain, limited non-conduction, pulling pain when bending to the opposite side, local closure can be effective, if long-term non-healing, feasible transverse synovectomy.
3, spinal synovitis: the disease is also a chronic injury inflammation, the site of inflammation in the synovial membrane, with each weight-bearing symptoms increased, bending activities are limited, the spine next to the pressure pain, no lower limb radiation pain, available physical therapy massage and non-steroidal anti-inflammatory drugs, if the synovial tissue hypertrophy, frequent attacks, affecting life and work, feasible small joint capsule and synovectomy.
4, other causes of low back pain: abdominal pelvic tumor, inflammation, lumbar intervertebral herniation, lower lumbar instability.
Treatment
Prevention-oriented, reduce the incidence advocate the correct working posture, improve the posture regularly, and carry out physical exercise comprehensively. Timely treatment of acute injuries, work and rest should be combined with work and rest.
1, self-care: proper rest, lumbar and back muscle exercise, increase muscle strength, enhance the ability to compensate for regulation, the symptoms of the more serious people can be used to protect the waist circumference.
2.Physiotherapy, massage, massage.
3.Pain point local seal.
4.Non-steroidal anti-inflammatory agents are available for heavy pain, such as etofenacin gel and oral Nimesulide dispersible tablets are good for external use.
5.Chinese herbal medicine: relaxing the tendons and activating blood circulation, relieving pain: Shu tendons and activating blood circulation tablets, tambourine pills, safflower oil and pain relief cream.
