This patient is a 63-year-old man who has suffered with lower back pain and right leg pain for several years. His pain tends to increase with standing and ambulation. When his pain initially began, he got relief with over-the-counter medications (i.e. Advil, Tylenol). He then began to receive epidural steroid injections, which lasted for a while but the pain soon returned.
His MRI lumbar spine showed a herniated disc at L2/L3 and a grade 1 spondylolisthesis at L4/L5. Both of these findings were contributing to the patients back and leg pain.
The grade 1 spondylolisthesis at L4/L5 requires both decompression at the L4/L5 level but also fusion because of the instability with motions. Here are three standing x-rays: one in the neutral position, one in flexion, and one in extensions. Notice the movement in the vertebral bodies at L4 and L5. This is abnormal motion and it can contribute to back pain and increase stenosis in certain positions. Thus, it requires decompression and stabilization with fusions.
The herniated disc only requires decompression and removal of the herniated disc. Notice in the same flexion extension dynamic x-rays. There’s no abnormal motion at the L2/L3 level.
Dr. Imani was able to decompress both the L2/L3 level (with disc herniation removal) and the L4/L5 level. Additionally, L4/L5 level was fused using titanium screw and an expandable interbody cage. This was performed with a very small incision. The patient has no more leg pain and back pain, and is doing very well!
