PLIF without Reduction in Non-traumatic Lumbar First to Second Degree Spondylolisthesis. A 3-Year Follow-up Study
OBJECTIVE: To investigate whether reduction of 1st to 2nd degree spondylolisthesis is required to relieve low back pain. The hypothesis was that spinal stabilization with arthrodesis using titanium cages might be enough to treat the patients' symptoms.METHODS: 32 cases of 1st to 2nd degree degenerative spondylolisthesis were operated upon with laminectomy and interbody fusion using titanium cages during the last 3 years. No additional instrumentation, such as a pedicle screw system, was used. Neurological symptoms and signs if present and low back pain were assessed preoperatively and monitored postoperatively for at least 2 years. RESULTS: Fusion was assessed radiologically. Solid fusion of the operative intervertebral level was achieved in 25 cases (78 %), and nonunion was detected in 7 cases (22 %). Excellent (90-100%) or very good (80-90%) pain relief was observed in 68.8 % of the patients. Eight patients had a good recovery with full resolve of neurological symptoms and adequate low back pain relief. One patient developed spondylitis with vertebral body erosion and displacement of the cages, and another one, hardware failure. CONCLUSIONS: Stabilization of the lumbar spine alone without reduction of 1st to 2nd degree spondylolisthesis might be sufficient to relieve pain. In the majority of the cases, it is a clinically safe, easy, and economic technique to treat lumbar degenerative spondylolisthesis.
