The herniation of the lumbar disc occurs due to degeneration of the disc, causing the nucleus pulposus to protrude backwards from the ruptured annulus fibrosus, compressing the spinal cord and nerve roots, thus leading to a series of symptoms. There will be pain in the lumbar region, and restricted flexion and extension movements of the waist. Symptoms may include numbness in the lateral calf and dorsum of the foot, weakness in walking, decreased muscle strength in the dorsiflexion of the big toe and ankle. In severe cases, there may be loss of control over urination and defecation. Therefore, when a disc herniation occurs, it is important to diagnose and treat it early to avoid worsening of symptoms.

Can a second surgery be performed for lumbar disc herniation?

Firstly, it should be clarified that for patients with lumbar disc herniation, if the condition recurs after surgery, a second operation is completely feasible. This is because there are many intervertebral discs involved, including L3-L4, L4-L5, and L5-S1, all of which can lead to lumbar disc herniation and subsequently cause symptoms of back and leg pain. Even if the patient has already undergone surgery for L4-L5, it cannot be guaranteed that L3-L4 or L5-S1 will not develop disc herniation. Therefore, it is possible for patients with lumbar disc herniation to undergo a second surgical treatment.

How to relieve stiffness in the lower back caused by lumbar disc herniation?

Lumbar disc herniation is very common in clinical settings. The peak incidence age is around forty, typically in middle-aged adults, though some cases occur in the elderly due to degenerative lumbar changes, bone proliferation, or osteoporosis-induced herniation. Patients with lumbar disc herniation usually experience discomfort in the lower back, muscle spasms, and sometimes numbness and soreness in the legs. If such stiffness and discomfort occur, one approach is to rest in bed. Additionally, applying heat, gentle massage, and treatments to relieve muscle spasms can be beneficial. Treatments such as acupuncture and physiotherapy can also help alleviate muscle spasms in the lumbar region, thus easing the stiffness.

What are the methods for diagnosing lumbar disc herniation?

The diagnostic methods for lumbar disc herniation are essentially three-dimensional; that is, clinical symptoms plus physical examination combined with auxiliary examinations. First, let's talk about clinical manifestations, which include pain, functional impairment, and local sensory abnormalities in cases of lumbar disc herniation. Second, in the physical examination of lumbar disc herniation, the intervertebral disc often shows some deformation, and the most common is a reduction or disappearance of the lumbar spine's forward physiological curvature, referred to colloquially as "flatback," where the back appears flat like a board. Other findings may include spinal scoliosis and specific tender points, usually located next to the protruding vertebrae. Percussing these tender points may induce radiating pain to the buttocks or lower limbs. Additional examinations might reveal abnormalities in the strength or sensation of lower limb muscles at different stages, as various muscles and sensory areas are affected differently. Special tests such as the straight leg raise test, femoral nerve stretch test, and neck flexion test are generally positive. The most routine auxiliary examination involves taking x-ray images, followed by CT scans, which can directly visualize the location and extent of the disc herniation. Currently, magnetic resonance imaging (MRI) is also used, which has significant advantages. MRI provides three-dimensional images, showing the sagittal, coronal, and axial planes, which helps in better assessing the condition of herniated discs. Therefore, these are the areas covered in diagnosing lumbar disc herniation.

How to diagnose a lumbar disc herniation?

Lumbar disc herniation often occurs due to degeneration of the lumbar spine, where the nucleus of the disc protrudes through the ruptured annulus fibrosus backward, compressing the spinal cord or nerve roots. This results in pain in the lower back, limited mobility of the lumbar region, and symptoms such as numbness, pain, and weakness in the lower limbs. For lumbar disc herniation, it is recommended to visit the orthopedic or spine surgery clinic of a standard hospital. Diagnosis should be confirmed with a physical examination by a doctor, along with imaging tests such as CT or MRI. These tests help determine the presence and extent of the disc herniation, and the affected segments. The treatment approach should be chosen based on the severity of the herniation.
