Acute lumbar sprain, commonly known as flash waist, is an acute laceration caused by sudden overstretching of soft tissues such as lumbar muscles, fascia, and ligaments due to external forces. . Acute lumbar sprain can tear tissues such as the attachment points of the lumbosacral muscles, periosteum, fascia, and ligaments.
Causes of acute lumbar sprain
There are two main reasons for lumbar soft tissue injury:
1. Lumbar sprain
It is mostly caused by walking, slipping, jumping, twisting the body, and running, and it is mostly caused by the restraint of muscles and ligaments, so the damage is relatively minor.
2. Lumbar contusion and laceration
It is a more serious injury, such as excessive force or excessive force in the process of climbing, pulling, and carrying heavy objects. Improper posture and improper coordination can cause injuries and tears to the muscle fascia, ligaments, intervertebral facet joints and joint capsules of the waist.
Symptoms of acute lumbar sprain
The patient has low back pain immediately after the injury, which is persistent and severe, and may be caused by local bleeding, swelling, low back pain the next day More serious; some just twisted the waist slightly, and there was no obvious pain at the time, but the next day after the rest, the waist was painful.
Limited movement of the waist, unable to straighten, difficulty in pitching, tilting, and twisting, and exacerbating pain when coughing, sneezing, and urinating.
He often supports his waist with his hands when standing, and supports his hands on a chair when sitting to relieve pain.
Pain on one or both sides immediately after a psoas sprain; sometimes the pain may not appear until half a day or overnight after the injury, the movement of the lower back is hindered, the pain is milder at rest, and the pain is worse when moving or coughing. During the examination, local muscle tension, tenderness and traction pain were obvious, but there was no congestion.
How to deal with a sprained waist
1. Lie down as soon as possible
As soon as possible after a sprained waist Lie down and reduce the stress on the myofascial tissue or the pressure on the lumbar spine to relieve pain. Severe sprains should rest in bed for at least 5-7 days.
2. Cold compress
Wrap the ice cube in a plastic bag and wrap it with a thin towel, or directly soak the towel in cold water and apply it to the painful area , can directly relieve pain, and more importantly, cold compresses can constrict capillaries and reduce bleeding of muscle and fascia. Change the towel every 1-3 minutes, 5-10 times in a row. The time of application should not be too long, otherwise it will affect the normal circulation of blood and be counterproductive.
3. Do not massage
Do not blindly massage in the acute stage, otherwise it will aggravate the bleeding of the muscle and fascia, or cause intervertebral disc damage.
4. Hot compress
After 48 hours, the damaged capillaries have stopped bleeding, and hot compress can be used at this time. Hot compress can promote the absorption of congestion and blood circulation, so that the soft tissue can be repaired as soon as possible.
5. Physical therapy
After the symptoms of pain and spasm are improved, some physical therapy can be done appropriately to speed up the recovery of the injury. There are many ways of physical therapy, including manual reset, infrared rays, local massage, acupuncture and external application of traditional Chinese medicine, etc., which should be determined according to individual circumstances.
6. Medication
During bed rest, topical analgesic and antispasmodic, hemostasis and swelling ointments (such as Voltaren cream, Yunnan Baiyao spray, etc.) can be used, But be careful not to use it when the skin is damaged. When necessary, anti-inflammatory analgesics and neurotrophic drugs can be added.
TIPS: If you only have low back pain, and no symptoms of nerve compression such as leg pain, numbness, weakness, and bowel and bladder disorders, it is recommended not to rush to the hospital for examination. If there are symptoms of nerve compression, it is very likely that a lumbar disc herniation has occurred, and it is recommended to go to the hospital for examination. If there is only low back pain and it does not improve after 3-5 days of bed rest, it is recommended to go to the hospital for examination and treatment to avoid developing chronic low back pain.
Treatment of acute lumbar sprain
Acute lumbar sprain should be bed rest. Those with obvious tender points can use 1 percent procaine (or add 1 ml of hydrocortisone acetate) to seal the pain points, supplemented by physical therapy. Local application of blood-activating, stasis-dispelling and pain-relieving plaster can also be applied. After the symptoms are relieved, gradually start the exercise of the lower back muscles.
Prevention of acute lumbar sprain
1. It is necessary to publicize and educate employees, strictly abide by operating procedures, be familiar with production techniques, prevent recklessness, and prevent and reduce work-related injuries. incidence.
2. Improve working conditions as much as possible and replace heavy manual labor with mechanical operations. Pay attention when working, especially when collectively lifting heavy objects, you should work together and move in unison under unified command.
3. Master the correct working posture. For example, when carrying and lifting heavy objects, try to keep the chest and waist straight, and bend the hips and knees. When you stand up, you should focus on the lower limbs. When moving and lifting heavy objects, you should take a semi-squatting position, so that the objects are as close to the body as possible.
4. Strengthen labor protection, and use belt
support when doing heavy physical labor such as carrying, lifting, moving, and lifting to help stabilize the lumbar spine, increase abdominal pressure, and enhance muscle work efficiency. If you work in a cold and humid environment, you should take a hot bath to remove the cold and dampness and relieve fatigue. Try to avoid working in stooping forced positions for too long.
