FORT LAUDERDALE, Fla., May 21, 2025 /PRNewswire/ -- In a landmark publication featured ahead of print in The Spine Journal , Dr. Kingsley R. Chin—board-certified orthopedic spine surgeon, professor, and founder and CEO of KIC Ventures—has achieved a major breakthrough for the interventional spine community. This multicenter, prospective randomized controlled trial is the first to rigorously evaluate the safety and procedural competency of sacroiliac joint (SIJ) fusion performed by interventional pain management (IPM) physicians trained using the Sacrix® posterior-oblique technique under direct supervision by board-certified spine surgeons.
SIJ fusion was traditionally the domain of spine surgeons, typically performed through a direct lateral approach. With the rise of percutaneous techniques, more IPM physicians are adopting the procedure—particularly in outpatient settings—prompting widespread debate around training standards and patient safety.
Study Highlights:
- 276 patients treated across multiple ambulatory surgery centers
- 47 IPM physicians trained by Dr. Chin using a standardized surgeon-developed curriculum
- Two randomized groups:
- Group 1: Supervised by board-certified spine surgeons
- Group 2: Supervised by clinical specialists or sales representatives
- Group 1 Results: 0% complications, deviations, or revisions
- Group 2 Results: 4.3% complication rate; 2.4% revision rate
"This study validates a new training paradigm that empowers IPM physicians to perform SIJ fusions safely and effectively when properly trained by spine surgeons," said Dr. Kingsley R. Chin. "As we move spine surgery into outpatient settings and embrace interventional approaches, surgeon-led education becomes more essential than ever."
To date, Dr. Chin and his team have trained over 400 interventional pain physicians in Sacrix® and LESS Exposure Spine Surgery techniques. In 2025, they launched the Visit. Education. Training. (VET) Tour at their headquarters at 6550 North Federal Highway, Suite 510, Fort Lauderdale, FL 33308 . The facility features state-of-the-art operating rooms designed for hands-on cadaver and didactic training, offering physicians the opportunity to:
- Discuss indications for surgery with expert faculty and key opinion leaders (KOLs)
- Practice instrument handling and procedural steps
- Provide real-time feedback on improving technologies
This immersive program fosters collaboration between surgeons and IPM physicians to ensure safe adoption of interventional spine procedures in outpatient settings.
The publication has received widespread praise from contributors and key opinion leaders:
"Wow… thank you so much for letting me be a part of this important study. It's truly an honor to be included among such a talented and dedicated group. You are both a gentleman and a scholar, and I'm grateful for your leadership in pushing our field forward. This publication is a huge win for the interventional pain community and a testament to what collaboration and vision can achieve." — Dr. Paul Ky, Interventional Spine Specialist
"As an orthopedic spine surgeon who has trained IPM physicians firsthand, I see this study as a blueprint for the future. It proves we can share techniques safely through structured education and elevate patient care across specialties." — Dr. Erik Spayde, MD, Harvard-Trained, Board-Certified Spine Surgeon
The study utilized the Sacrix® system with titanium screw fixation and NanoFuse Biologics—a synthetic, bioactive bone graft. The posterior-oblique approach was designed for reproducibility, safety, and efficiency, making it ideal for ambulatory surgery centers (ASCs) amid rising demand for LESS invasive spine procedures.
This publication marks a pivotal step forward in the evolution of interventional spine surgery. It offers a validated framework for bridging the gap between specialties through collaborative, surgeon-led training—ultimately delivering safer outcomes for patients worldwide.
