A middle-aged patient was admitted to the hospital with the complaint of “recurrent low back pain with left lower extremity radiating pain for more than 2 years, with pain worsening and difficulty walking for 10 days. A few years ago, he developed lumbar distension and pain after exertion, accompanied by hip and left lower extremity posterior radiating pain, which could be relieved by lying down at rest. 10 days ago, due to prolonged bending, the hip and left lower extremity posterior radiating pain increased, and the pain was severe when standing and walking, accompanied by left plantar numbness and weakness of left foot lifting, which could not be relieved by lying down at rest. On examination, the left Achilles tendon reflex was weakened, the left plantar flexor strength of the left underside of the toes was decreased, and the left plantar sensation was slightly decreased. MRI of lumbar spine showed: lumbar 5-sacral 1 disc herniation with prolapse and sacral 1 nerve root compression. After admission, neurotrophic and dehydration treatment and epidural nerve block treatment were given, and the symptoms were relieved, but the pain and numbness from bed activities were still obvious. The patient’s pain and numbness in the waist and left lower extremity were relieved immediately, and muscle strength was restored. 3 days after surgery, MRI showed that the herniated disc was removed and the nerve roots were repositioned. This patient had “recurrent lumbar pain with left lower extremity radiating pain for more than 2 years, pain aggravated with walking difficulty for 10 days”, and had a herniated lumbar disc 2 years ago, probably because the herniation was not large and the pressure on the nerve root could be relieved by rest. This time, the nucleus pulposus tissue prolapsed again from the rupture of the fibrous ring to the spinal canal due to prolonged bending, stimulating the compression of sensory and motor fibers of the nerve roots, causing pain, numbness and decreased muscle strength in the lumbar and lower limbs. MRI of the lumbar spine showed that the lumbar 5-sacral 1 disc was herniated with prolapse and the sacral 1 nerve root was compressed. The patient was considered to have “lumbar disc herniation (lumbar 5-sacral 1 prolapse type)” by combining medical history, physical examination and imaging and other auxiliary examinations, and “percutaneous foraminoscopic removal of herniated disc” was performed to relieve the nerve compression, and the patient’s symptoms were immediately relieved. In fact, lumbar disc herniation is not terrible, as long as the diagnosis is clear, foraminoscopic minimally invasive technology to accurately remove the herniated disc, immediate relief of pain, less trauma, less risk, low cost, fast recovery.
