Compression of the anterior edge of the dural sac and the intervertebral foramen may be caused by disc herniation, calcification of the posterior longitudinal ligament, and so on. There are different treatments for different causes, and common treatments include general treatment, physical therapy, medication, and so on.
1. Herniated disc: A herniated disc will compress the dural sac and intervertebral foramen located behind it, resulting in pressure on the spinal cord and nerve roots, and symptoms such as difficulty in movement and numbness in the limbs. Lumbar traction therapy can be used to increase the lumbar spinal space, allowing the herniated disc to partially retract. Physical therapy such as acupuncture and massage can also be used to promote blood circulation.
2. Calcification of the posterior longitudinal ligament: When calcium salts are deposited in the local tissues of the posterior longitudinal ligament, calcification of the ligament is likely to occur, which compresses the nearby dural sac and intervertebral foramen. Hot compresses can be applied to the affected area, or ultrasound, electromagnetic wave and other physical therapy can promote local blood circulation, which is conducive to the recovery of calcification of the posterior longitudinal ligament. Drugs that activate blood circulation and eliminate blood stasis such as Panax ginseng ointment can also be used to repair the posterior longitudinal ligament.
In addition, the compression of the anterior edge of the dural sac and the intervertebral foramen may also be due to vertebral fracture, lumbar spondylolisthesis and so on. It is recommended to go to the hospital in time to identify the cause of the disease and treat the symptoms under the guidance of the doctor.
