Sacroiliac (SI) Joint Fusion Simplified
Management
Led by an experienced team of business and medical professionals, SI-BONE is uniquely positioned to make a dramatic impact on the treatment
options available for patients suffering from chronic unresolved low back pain.
Dr. Mark A. Reiley, Chief Medical Officer, Inventor and Founder
Dr. Mark Reiley is a board certified orthopedic surgeon with 20 years of
experience creating ground breaking products for the orthopedic marketplace. He is widely known as the inventor of four successful products
used in orthopedic and spinal surgery. Most recently, he was the Chief Medical Officer of INBONE Technologies, which was sold to Wright
Medical in April 2008.
Dr. Reiley co-founded Kyphon, which revolutionized the treatment of vertebral compression fractures of the spine.
With a presence in 43 countries and 5,000 annual surgeries, the kyphoplasty technique has changed the standard of care worldwide.
Following Kyphon Dr. Reiley developed the product line of Archus Othopedics, specifically their
TFAS system. This novel spinal implant is designed to treat spinal stenosis, a condition in which degenerative
changes in the facet joints result in compression of spinal nerves producing neurological symptoms in the legs.
Dr. Reiley then turned his attention to the foot and ankle, developing two revolutionary treatment options for patients suffering
from foot and ankle pain. He created an intramedullary small bone fusion system (ENDO-FUSETM ) used throughout the foot
to eliminate the pain of arthritic joints. He also designed an innovative Total Ankle Replacement (TAR), which is the first and only total
ankle replacement system to use intramedullary guidance. The TAR system offers a level of precision never before seen in the ankle
marketplace, and was quickly established as the most versatile and customizable option for patients. The INBONE Total AnkleTM
and ENDO-FUSETM System were acquired by Wright Medical in April of 2008. Dr. Reiley subsequently started SI-BONE in the
Spring of 2008.
Dr. Reiley has received a variety of medical awards and given keynote speeches at spine symposia worldwide. Dr. Reiley has published a
number of articles and books (both fiction and non-fiction), and continues to invent devices to further advance medical care worldwide.
Dr. Reiley earned his M.D. at George Washington University School of Medicine in Washington, D.C., and completed both his orthopedic
residency and fellowship at the University of California at San Francisco. He was a founding member of Berkeley Orthopedics Surgical group,
where he practiced for over 20 years. Dr. Reiley recently retired from active practice in January of 2009.
An Advanced Approach to Surgical Management of SI Joint Dysfunction
Up to 25% of all low back pain is SI Joint in origin – but the diagnosis of SI Joint disease is frequently overlooked. (Cohen, et al.)
It is common to link low back pain with protruding disc even when neurological signs are absent. (Weksler, et al.)
It is common for pain from SI Joint dysfunction to mimic discogenic or radicular low back pain. (Weksler, et al.)
Many patients go on to receive lumbar fusion instead of SI Joint fusion – so SI Joint disease should be strongly considered in differential diagnosis of low back pain. (Weksler, et al.)
Now there is an approach to surgical management of SI Joint dysfunction that’s easier and less invasive than traditional open surgery.
The iFuse Implant System consists of porous plasma spray coated implants, surgically inserted across the SI Joint to create fixation leading to fusion—from the inside.
The iFuse creates a biomechanically rigorous fixation/fusion system, designed to support reliable fixation/fusion and acute weight bearing capacity.
With the iFuse Implant System, there is no need for BMP in conjunction with autologous bone graft or additional pedicle screws, rods or hollow modular anchorage screws or cannulated compression screws or threaded cages within the joint or fracture fixation screws.
iFuse benefits:
- Less invasive than traditional open surgery with no extensive soft tissue stripping
- straightforward surgical approach
- implant profile and design minimizes rotation and micromotion
- rigid titanium implants provide immediate post-op si Joint stability
- porous plasma spray coating with irregular surface designed to support stable bone fixation/fusion
- 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 System is designed to be the sacroiliac joint fusion/fixation method of choice for spine surgeons.
iFuse is a minimally invasive surgical solution to replace open surgical SI Joint fusion.
With iFuse there's minimal incision size, minimal soft tissue stripping, minimal tendon irritation and reduced risk of infection.
iFuse is a simplified minimally invasive surgical procedure.
Just drill, broach, insert Implants and close.
iFuse has a simple technique which reduces OR time to less than 1 hour.
iFuse has 3X shear and 7X bending strength compared with screws.
iFuse has improved patient perception of stability post-implant.
The incidence of SI joint degeneration in patients was 75% at 5 years post-fusion, which was significantly higher than in the non-fusion group, 38.2%. (Ha, et al.)
Among patients with one-segment fusion, 91% developed SI joint degeneration. (Ha, et al.)
Regardless of whether the fusion includes the sacrum, the SI joint is influenced by increased mechanical stress arising from lumbar/lumbosacral fusion. (Ha, et al.)
Posterolateral lumbar/lumbosacral fusion can be a cause of SIJ degeneration. (Ha, et al.)
