Advances in Spine Care Could Save the U.S. Healthcare System Billions David P. Rouben, M.D. River City Orthopedic Surgeons Louisville, Ky. September, 2005

Cost of Low Back Pain Costs U.S. Billions The Common Cold-only medical condition treated more frequently than Low Back Pain 80% of U.S. Population experiences Low Back Pain Low Back Pain Incidence- 4 times faster growth than U.S. Population

Treating Low Back Pain Costs U.S. Billions 126 million in the U.S. Workforce Aging workers= Declining U.S. workforce 20% Workers Disabled for up to 6 mo/yr Injured Workers Lose Pay but Gain Disability Employers Face Recurring Costs of Injured Worker Medical Care Lost Productivity New Worker Recruiting-Retraining-Benefits

Cost of Low Back Pain Costs U.S. Billions U.S. Work Comp Injuries Cost $160 Billion in 2005 41% of Injuries are Low Back Pain 25 million Workers are off for 6 months 630,000 (2.5%) Workers Fail Non-Operative Tx

Cost of Low Back Pain Costs U.S. Billions Only 50% of Workers treated via “Traditional Open Lumbar Fusion Techniques” will return to work Only 27% of Workers undergoing More than One back surgery will Return to Work 50% of “Successful” Open Fusions Experience a Recurrence of Pain and Disability

Treating Low Back Pain Minimally Invasive Decompression Non-Surgical Treatments have Changed Little for 20 years Technical Advances in Surgery offer Improved Results Minimally Invasive Decompression Minimally Invasive TLIF / PLIF

Surgical Treatment Low Back Pain Goals- Speedy Return to Work Reproducible- Consistent-Efficacious Treatment Minimize Lifestyle Change-Disability

OPEN TLIF

MAST TLIF

MAST TLIF vs. OPEN TLIF By Comparison MAST TLIF Patients spend: 88% Less time in the Hospital 50% Less time in Recovery Room 50% Less Narcotics in Hospital 33% Less Blood Loss, No Transfusions 39% More Return to Work

MAST TLIF vs. OPEN TLIF Overall Savings: 45% Less or $24,336 Major Hospital/Procedural Cost savings: Recovery Room Charges: 59% Less, $682 In-Patient Hospital Charges: 97% Less, $13,601 Blood Transfusion Charges: 100% Less, $2,518

MAST TLIF vs. OPEN TLIF  

MAST TLIF vs. OPEN TLIF

MAST TLIF BENEFITS 70% Less Pain than before Surgery 90% Return to Work within 10 weeks

MAST TLIF only represents a small number of total TLIFs Training and Additional Data is needed to make MAST TLIF the new “Gold Standard”

Potential Cost Savings MAST TLIF 213,000 lumbar fusions will be performed in the U.S. in 2005 15% of all Lumbar Fusions (31,000)- Traditional Open TLIF’s

Potential Cost Savings MAST TLIF Change 31,000 Open TLIF’s To MAST ? $754 Million Savings

Potential Cost Savings MAST TLIF If All Lumbar Fusions performed as MAST $5.2 Billion Savings

MAST TLIF Published Data Schwender JD, Holly LT, Rouben DP, Foley KT. Minimally Invasive Transforaminal Lumbar Interbody Fusion (TLIF). Journal Spinal Disorders Technique. Volume 18, supplement 1, February 2005. 49 patients MAST TLIF Operative time averaged 240 minutes. Estimated blood loss averaged 140 mL. Mean length of hospital stay was 1.9 days. Improvements in average Visual Analogue Pain Scale and Oswestry Disability Index (preoperative to last follow-up) scores were 7.2-2.1 and 46-14, respectively. At last follow-up, all patients had solid fusions by radiographic criteria.
