Summary
Graf ligamentoplasty offers sustained relief for degenerative disc disease, with 62% of patients reporting good or excellent outcomes. This less invasive spinal stabilization procedure demonstrates long-term benefits in low-back pain management.
Area of Science:
- Spine surgery
- Orthopedic surgery
- Degenerative disc disease treatment
Background:
- Graf ligamentoplasty is a less invasive alternative to spinal fusion for symptomatic degenerative disc disease.
- Previous studies reported mixed early results due to unclear indications.
- Current indications for Graf stabilization are now better defined.
Purpose of the Study:
- To evaluate the long-term efficacy and patient outcomes of Graf ligamentoplasty.
- To assess the sustained benefits of the procedure in patients with degenerative disc disease.
- To correlate clinical outcomes with validated patient-reported measures.
Main Methods:
- Postal follow-up with 40 patients from an initial cohort of 50 who underwent Graf stabilization.
- Independent review of clinical records and radiographs.
- Assessment using Oswestry Disability Score, MSPQ, Zung Depression Index, and DRAM.
Main Results:
- 31 of 40 patients still had Graf instrumentation in situ after an average of 7.4 years.
- 62% of patients reported excellent or good subjective outcomes.
- Mean Oswestry Disability Score improved significantly from 59% pre-operatively to 37.7% post-operatively.
- Statistically significant correlation found between Oswestry scores and subjective outcome (P=0.009).
Conclusions:
- Graf ligamentoplasty provides sustained beneficial effects for low-back pain in the long term.
- The procedure remains effective despite the presence of ongoing degenerative processes.
- Long-term follow-up confirms the viability of Graf stabilization for specific degenerative spinal conditions.
