There are two main treatment options for lumbar 4-5 disc herniation backward: the first treatment option is strictly conservative treatment, which requires strict lying flat on a hard bed without bending, getting up, or getting off the floor during the acute attack period. It is also combined with three-dimensional computerized traction of the lumbar spine, microwave physiotherapy, mannitol as well as dexamethasone for a short period of time to do dehydration treatment. If after 2-3 weeks of strict conservative treatment does not work, or if the lumbar disc herniation is more serious, surgery can be considered, and minimally invasive intervertebral foraminal therapy is preferred for surgical treatment. If there are surgical limitations of intervertebral foraminoscopy, you can consider doing incisional surgical treatment to completely remove the lumbar 4-5 disc.
