Overview
Cervical stenosis can develop from osteoarthritis, bone spurs, disc herniations and degenerative disc disease. When conservative treatments are insufficient, a posterior cervical laminoplasty (PCL) may be recommended. Through a small posterior incision with the patient face-down, the surgeon partially cuts the lamina at both ends, creating a hinge on one side. The unhinged side opens like a door, increasing space around the spinal cord and reducing pressure. A spacer holds the door open in this open-door laminoplasty technique.
Benefits
- Outpatient basis or minimal hospital stay
- Smaller incisions reduce scarring and tissue trauma
- Faster recovery than open surgery with lower pain
- Low complication and infection risk
- No removal of spinal structures and typically no fusion required
- Less costly than rod-and-screw procedures; safer than anterior approaches
Who is a Candidate?
- Spinal compression symptoms or myelopathy
- Arm tingling or balance problems
- Loss of hand movement (assessed via X-rays and MRI)
Minimally Invasive vs Open Surgery
| Factor | Minimally Invasive | Open Surgery |
|---|---|---|
| Incision size | Small (often 8mm–2cm) | Large |
| Muscle damage | Minimal — muscles separated | More — muscles cut |
| Blood loss | Low | Higher |
| Post-op pain | Less | More |
| Hospital stay | Short (day-care to 1–2 days) | Longer |
| Scarring | Minimal | More visible |
| Return to activity | Faster | Slower |
| Infection risk | Lower | Higher |
