What Is Instrumentation Surgery?
Question: In which situations is instrumentation surgery considered?
Answer: When instability (abnormal mobility) between vertebrae is detected, the goal is to stabilize the spine using screws and rods. Its medical name is instrumented fusion.
Question: Are there disadvantages?
Answer:
- Reduced spinal movement at the operated level
- Risk of adjacent segment disease in the long term
- Studies in the literature report adjacent segment problems over the years in an approximate 10–30% range
Which questions should be asked before deciding on fusion?
- Is there truly instability?
- Are motion-preserving alternatives suitable?
- What are the long-term lifestyle effects?
