Types of Surgery and Their Risks — What Families Should Know
Three Main Surgical Approaches
Surgery
What it does
Physical burden
Hospital stay
Decompression
Removes bone and ligament pressing on the nerves
Relatively low
About 1–2 weeks
Fusion
Stabilizes the spine with screws and rods
High
About 2–4 weeks
SCS (Spinal Cord Stimulation)
Uses electrical pulses to relieve pain
Low
About 1–2 weeks
Risks That Are More Common in Elderly Patients
In addition to standard surgical risks, older patients face:
Risk
What it is
How common
Delirium
Temporary confusion and disorientation after surgery
About 13% after spine surgery in people aged 65+[1]
Pneumonia
A complication of general anesthesia
More common in older adults
Deep vein thrombosis (DVT)
Blood clots from post-surgical bed rest
Preventive measures are available
Infection
Surgical site infection
Healing is slower in older patients
Slower recovery
Takes longer than in younger patients
Varies greatly between individuals
Having risks does not mean surgery should be ruled out. The risks of surgery must be weighed against the risks of not having surgery, such as losing the ability to walk or becoming bedridden.
If Fusion Surgery Is Recommended — Proceed with Extra Caution
Why Fusion Surgery Requires Careful Consideration
Compared to decompression (which simply relieves pressure on the nerves), fusion surgery (which stabilizes the spine with screws) involves:
Factor
Decompression
Fusion
Surgery time
1–2 hours
3–5 hours
Blood loss
Low
Higher
Post-operative pain
Mild
Significant
Hospital stay
Shorter
Longer
Long-term risks
Fewer
Adjacent segment disease
When multi-level fusion (fusion at two or more levels) is needed, the physical toll is substantial, and there is an added risk of adjacent segment disease, in which the vertebrae above and below the fused section begin to break down over time.
SCS as an Alternative to Fusion
When multi-level fusion is being considered, SCS (Spinal Cord Stimulation) may be an alternative:
Comparison
Multi-level fusion
SCS
Physical burden
High
Low
Test stimulation before implanting
No
Available if you wish (these days the device is usually implanted in one go)
5. An Important Note About SCS (Spinal Cord Stimulation)
This page has mentioned SCS as one of the treatment options. SCS is not yet widely known as a treatment. This section explains why.
Why Isn't It Better Known?
SCS is well established in Western countries, but in some regions it has not yet been widely adopted by all orthopedic or neurosurgical spine specialists. As a result, your parent's current doctor may not be familiar with SCS. That does not mean it is unproven. Awareness of newer therapies can lag behind the evidence.
The Perspective of This Site's Supervising Physician
The orthopedic spine surgeon who supervises this site has over 20 years of experience treating spinal conditions. Based on that clinical experience, particularly for elderly patients who would need multi-level fusion surgery, SCS is worth exploring before committing to a major operation.
For Family Members
Start by reading about SCS on this site to see if it might be relevant to your parent's situation
Bring it up with your parent's doctor. A doctor who is open-minded will be willing to discuss it or refer you to a specialist center
If the current doctor is not familiar with SCS, don't give up. Specialist centers and consultations are available
SCS is not an unproven treatment. It is a recognized medical procedure covered by health insurance, using regulatory-approved medical devices. Not every doctor knows about it yet. Learning about it helps your parent have access to every available option.
Questions to Ask Your Doctor
Consider asking these questions at your next appointment:
"Is my parent's overall health good enough for surgery?"
Understand the assessment beyond just age
"What are the specific risks for someone with their medical history?"
Get a personalized risk assessment, not just general statistics
"What is the expected timeline for recovery?"
Set realistic expectations for rehabilitation and return to daily life
"If we try conservative treatment first, what signs should prompt us to reconsider surgery?"
Know the triggers for revisiting the surgical option
