Comparison of post surgical results in medial and lateral lumbar spine herniated discs: own case series experience

Lumbar disc herniation is a frequent condition. It causes radicular pain with irradiation along a lower limb or localized to the back. Disc herniation can be lateral or medial, with different clinical features. Medial disc herniation is more frequent, characterized by immediate good outcome after surgical treatment. Lateral disc herniation shows a greater delay in improvement on pain after surgical treatment, especially in the elderly. Some factors affect the surgical outcome, such as old age, alterations of the vertebral body, ligaments, intervertebral level. Our study is in line with these data, highlighting the better outcome, immediately after the surgical treatment in patients with medial disc herniation, while results has not been immediate in patients with lateral disc herniation, Finally, there was disappearance of the pain for both groups, as demonstrated in the long-term follow-up, after the surgical treatment
