Marshall Health Network neurosurgeon marks 300th surgery for sacroiliac (SI) joint dysfunction

Wednesday, July 22, 2026

Marshall Health Network-St. Mary’s Medical Center neurosurgeon Dwight Saulle, M.D., FAANS, has reached a significant milestone after successfully performing his 300th surgery to treat sacroiliac (SI) joint dysfunction using SI-BONE's® iFuse Implant System.  

The SI-BONE procedure is a minimally invasive surgical solution designed to relieve chronic pain in the SI joint, which connects the spine to the pelvis and can be an often-overlooked source of lower back, hip and leg pain. Saulle’s extensive experience places him among the leading providers of SI joint care. This milestone demonstrates surgical skills as well as a commitment to helping patients regain mobility and quality of life. 

“Reaching this milestone reflects the trust patients place in our team and our commitment to offering advanced spine care close to home,” said Saulle, a board-certified neurosurgeon with more than 18 years of experience. “SI joint dysfunction can have a major impact on everyday life, and it is rewarding to help patients find relief, restore function and return to the activities they enjoy.” 

Patients undergoing the SI-BONE procedure often experience reduced pain, improved stability and quicker recovery times compared with traditional surgical methods. The triangular shape of the implant helps prevent movement in the SI joint, providing immediate stabilization. Over time, the bone grows around the implants, leading to long term fusion and pain relief.
