A lumbar disc prolapse is actually a type of lumbar disc herniation. The lumbar disc herniation, as commonly referred to by the people, contains disc bulge, disc herniation, disc prolapse, and even disc free. The lumbar disc shedding is the lumbar disc prolapse, which is already the third stage and is a more serious stage of disc damage, and the continued development is the free, i.e. the herniated fragments completely fall into the spinal canal to compress the nerves. Generally speaking, the diagnosis of lumbar disc prolapse must be a nuclear magnetic diagnosis, CT or X-ray can not make the diagnosis. The treatment is as follows: 1. If there are no symptoms of leg pain at all, the next step is conservative treatment or surgery according to the MRI diagnosis; 2. If the condition is more serious, accompanied by leg pain, and the condition is more than 3 months old, it is an indication for surgery and must be treated surgically. If there are problems with urination and defecation and foot drop, even emergency surgical treatment is required, otherwise it may lead to disability. Overall, prolapsed lumbar disc is a more serious condition and most will likely require surgical treatment.
