Anterior Hip Replacement Using the Tri-Lock® Bone Preservation Stem

Thin geometry and optimized length minimize the amount of bone removed from the patient.

Your Time:
From Bozeman Deaconess Hospital in Bozeman, MT

In a live Internet web cast on November 20, 2008, at 5:00 p.m. Eastern Time, Daniel Gannon, M.D., will perform a direct Anterior Approach total hip arthroplasty (THA) with the Tri-Lock® Bone Preservation Hip Stem. The Tri-Lock Hip System is a new tapered-wedge titanium stem from DePuy Orthopaedics, Inc. that is engineered to help preserve the patient's bone as compared to a traditional dual tapered stem.

"The new Tri-Lock Bone Preservation Stem is less invasive when compared to more traditional systems while maintaining the 27-year clinical heritage of the Tri-Lock philosophy, with advancements in implant and instrument design enabling the surgeon's preferred technique," explains Dr. Gannon. "This hip system is engineered to offer a high level of stability and can be combined with many of DePuy's high performance bearing products, including metal-on-metal and ceramic-on-polyethylene, that can potentially reduce wear." 

The live surgery will be performed at the Bozeman Deaconess Hospital in Bozeman, Montana. As one of the designing surgeons for the Tri-Lock Hip System, Dr. Gannon has been instrumental in surgeon education with this new product offering. DePuy Orthopaedics, Inc., a company that has taken a leading role in educating surgeons, is making the broadcast available for free via www.OR-Live.com.

Traditional Hip Replacement Vs. the Direct Anterior Approach
Dr. Gannon will use the direct Anterior Approach to total hip replacement during this procedure. The direct Anterior Approach is a tissue-sparing technique for total hip replacement. With the direct Anterior Approach, surgeons approach the hip joint from the front as opposed to the side or back so they can work between the muscles without detaching them from the hip or thighbones.

"The advantages of the direct Anterior Approach are that it allows for a smaller incision and less tissue disruption, when compared to traditional total hip replacement, which can shorten the recovery process. Additionally, patients may bend their hip and bear full weight sooner after this surgery than other types of hip replacement surgery," says Dr. Gannon.

About Hip Replacement
The demand for hip replacement is growing rapidly. It is estimated that the number of primary total hip replacements will increase by 174 percent -- to 572,000 -- in 2030. This is due in part to the growing number of Baby Boomers with osteoarthritis and the rise in obesity among the population.1

Important Safety Information
As with any medical treatment, individual results may vary. Only an orthopaedic surgeon can determine whether an orthopaedic implant is an appropriate course of treatment. There are potential risks, and recovery takes time. The performance of the new joint depends on weight, activity level, age and other factors.
