Specializing in Spine Surgery Treatment of the Injured Back & Adult Reconstruction
Mathew Phillips, M.D.

Spine surgeon, is a member of the Spine Care Team at the Orthopaedic Center of Southern Illinois. 

Dr. Mathew Phillips is fellowship trained in Advanced Spine surgery and Sports Medicine. He grew up in Central Illinois and went to University of Illinois for his undergraduate degree, then attended medical school at Rush University, Chicago. His Orthopaedic surgery residency was performed at Saint Louis University Hospital, St. Louis, Missouri, and Orthopaedic Spine Surgery Fellowship at Spine Surgery PSC, in Louisville, Kentucky. Dr. Phillips also completed an Orthopaedic Sports Medicine Fellowship at Cincinnati Sports Medicine and Orthopedic Center in Cincinnati, Ohio.

Dr. Phillips has special interests in acute and chronic conditions involving the cervical, thoracic, lumbar spine, as well as SI Joint Fusion

Whether you are looking to alleviate back and neck pain, improve movement or simply participate in everyday activities, the Spine Care Team is here to help - from an initial assessment to a customized treatment plan that is right for you. Understanding your spine and how it works can help you better understand some of the problems that occur from aging or injury.

Watch as Dr. Mathew Phillips and Braedon Haertling, PA-C discuss "Low Back Pain's Missing Piece - Diagnosing the Sacroiliac Joint" during a webinar sponsored by Orthopaedic Center of Southern Illinois and SI-Bone, Inc.

Dr. Phillips has clinics at the Mt. Vernon and Centralia locations. To schedule an appointment with Dr. Phillips, please click here.

SI Joint Fusion With The iFuse Implant System®

The procedure used by Dr. Phillips is the most common: the iFuse Implant System, developed by SI-Bone, Inc., of San Jose, California.

The iFuse is a minimally invasive surgical option, designed to be easier and less invasive than traditional open surgical SI joint fusion. The iFuse Implant System is indicated for sacroiliac joint fusion for conditions including sacroiliac joint disruptions and degenerative sacroiliitis. The procedure typically involves three small titanium implants surgically inserted across the SI joint. It is designed to create a durable construct to stabilize the SI joint. The procedure is done through a small incision and takes about an hour. The surgeon determines the release time based upon post surgical progress and occupation. Post-operative pain is usually isolated to the incision area. 

With the iFuse Implant System, there is no need for: BMP in conjunction with autologous bone graft, additional pedicle screws and rods, hollow modular anchorage screws, cannulated compression screws, threaded cages within the joint, or fracture fixation screws.

In a randomized controlled trial, 80 percent of the patients that had the iFuse procedure med the strict success criteria, and 90 percent of the patients were satisfied and would have the procedure again. Long-term pain relief and improved function have been demonstrated in three publications, sharing results up to five years.

iFuse Potential Benefits:

  • Less invasive than traditional open SI joint fusion surgery with no extensive soft tissue stripping
    • Plus: minimal incision size (approximately 2-3 cm long) and minimal tendon irritation
  • Straight forward minimally invasive surgical approach
  • Designed for maximum joint stability
    • Triangular implant profile minimizes rotation and an interference fit minimizes micromotion
    • Rigid titanium constructs provide enhanced stability
    • Porous plasma spray coating
    • Larger implant surface area designed to maximize post-surgical weight bearing capacity
    • Biomechanically rigorous implant designed specifically to stabilize the heavily loaded SI joint
    • The iFuse implant has 3X shear and 7X bending strength compared with screws1

Simplified surgical procedure with iFuse

  • Pin, drill, broach, insert implants, and close
  • Procedure takes about an hour
  • Potential for less blood loss and reduced soft tissue stripping
