Dear patient. Greetings from health care magic!!! I am Dr Thakker and shall be answering your question. MRI is an imaging technique which helps us to delineate the soft tissue anatomy in a body part. I will explain the results of your MRI as follows: 1)Mild loss of lumbar lordosis: Human spine has an s shape given by nature. Spine has the following parts: cervical (neck); thorax (chest); lumbar (back), sacrum, coccyx. Of these, the lumbar area had a convexity forward in a normal state. This convexity of the spine is lost in your case. This could be because of muscle spasm secondary to disc prolapse. 2) Flaval hypertrophy noted from L1-2 to L4-5: Ligamentum flavum is a yellow colored ligament that supports the vertebra to each other and stabilises the joints in the vertebra especially between the spinous processes. This ligament is thickened in your case. It means it has been exposed to serious strain causing it to get thickened. 3)Posterior disc bulge with small right paracentral disc herniation at L3-4, indenting thecal sac minimally abutting the traversing right L4 nerve root : The vertebra in the human spine are separated from each other by a cushion called as the intervertebral disc. In your case the cushion between the 3rd and the 4th lumbar vertebra has slipped and moved back. because of this it compresses the nerves which are present behind the cushion in the spina cord. this cushion is touching yout right 4th lumbar nerve. This implies you have a prolapsed intervertebral disc with nerve abutment. You may need traction treatment, lumbar discectomy as a modality of treatment. Supportive treatment in the form of pain relievers and muscle relaxants can be given. I would suggest you to take an opinion of an ortho doctor and plan the treatment ahead. I hope this helps you out. If you have any more questions, please do not hesitate to write back to me. Yours sincerely, Dr Thakker.
