A new study published in Spine examines adjacent segment disease risk factors for patients 10 years or more after posterior lumbar interbody fusion.
The study authors examined patients with disc degeneration and spinal stenosis on an MRI to identify risk factors for developing early-onset radiographical adjacent segment disease using the multivariate logistic regression analysis.
The researchers found:
1. Ten years after surgery, the patients showed at the caudal-adjacent level:
• Changes in disc height: 12 cases
• Vertebral slip: 36 cases
• Intervertebral angle on radiographs: 17 cases
