Grade 1 Spondylolisthesis New York City
A 54-year-old male management-consultant and fitness enthusiast presented to Dr. Stieber complaining of low back pain. The patient had experienced low back pain for more than one year and graded it at a 10/10 at its worst and 7/10 on average.
Previous treatments include anti-inflammatory medications, Prednisone, Vicodin, muscle stimulation, formal physical therapy, therapeutic massage, and epidural steroid injections. Non-surgical treatment only provided limited relief.
The patient’s exam revealed markedly decreased lumbar (low back) spine range of motion secondary to substantial pain with palpable muscle spasm.
Pre-operative x-rays demonstrated a Grade I degenerative spondylolisthesis with instability on flexion-extension radiographs (Figures 1, 2). MRI findings (Figure 3) revealed disc bulging and uncovering of the intervertebral disc in addition to spondylolisthesis.
