Minimally invasive surgery

What it is

Minimally invasive surgery is not a different operation — it is a different corridor to the same surgical goal. Where a traditional open approach uses a longer incision and retracts broad swaths of muscle to see the spine, a minimally invasive approach reaches the target through a small, precisely planned passage. The decompression, the implant, the fusion — the work itself — is unchanged; what changes is how much healthy tissue is disturbed getting there.

Smaller corridors mean less muscle stripping, less blood loss, and less postoperative pain — which typically translates into a faster recovery and a shorter hospital stay.

The tools

Dr. Choi uses instruments designed for narrow corridors: tubular retractors that gently dilate muscle rather than cutting it, the operative microscope for magnified illumination, and endoscopic visualization — a high-definition camera and fine instruments working through a channel roughly the width of a fingertip. Computer-assisted navigation can add real-time guidance for precise trajectories.

Each is a tool, not the operation itself. Open, traditional minimally invasive, and endoscopic approaches share the same surgical goal and generally the same outcomes — what differs is the corridor: incision size, muscle disruption, anesthesia, and recovery speed. The corridor is chosen around the patient's anatomy and the pathology being treated.

When it may be considered

Many decompressions, discectomies, and fusions can be performed through minimally invasive corridors — but not every case is a candidate. Complex deformity, certain revision scenarios, and multilevel pathology may still call for a traditional approach. The right corridor is a patient-specific decision, made from a clear diagnosis with an honest discussion of the tradeoffs.

What to discuss at consultation

• Goals: treat the exact target with the least disruption to healthy tissue.
• Alternatives: a traditional open approach, or continued nonoperative care where appropriate.
• Recovery: typically less pain, a shorter stay, and a faster return to activity than the open equivalent — though timelines still depend on the procedure itself.
• Risks: the risks of the underlying operation remain; a smaller incision does not make surgery risk-free — discussed plainly before any decision.
