Morton Grove, IL (PRWEB) January 14, 2007
Dr. Steven Haddad, an Illinois Bone and Joint Institute (IBJI) surgeon practicing in Glenview, Illinois, is one of only six surgeons in the country who have access to a new, upgraded version of the Agility Ankle LP Prosthesis that provides patients with a longer-lasting implant.
"There is remarkable improvement in the newly designed prosthesis," said Dr. Haddad. "This prosthesis is more stable than the previous design and poses a substantially lower risk of sinking into the patient's bone. This issue occurs as early as two to three years after the surgery, is one of the more serious complications of ankle replacement surgery and can lead to the failure of the implant."
The increased stability of the prosthesis is expected to result in less patients requiring additional surgery. Currently, about 35% of patients require additional surgery within 14 years following ankle replacement. Like unbalanced tires on a car, unstable artificial ankles wear unevenly due to friction between the metal edge of the prosthesis and the plastic liner within the joint. Such tilting of the components is possible due to the instability of the ankle ligaments or a pre-existing deformity and may require revision surgery to re-align the ankle implant. A more stable prosthesis has fewer tendencies towards tilt and enhances the durability of the implant, according to Dr. Haddad.
The three main reasons that patients require ankle prostheses are trauma, systemic conditions such as rheumatoid arthritis and general joint deterioration from osteoarthritis. Anyone requiring ankle replacement surgery will benefit from the improved design of the Agility Ankle LP, but individuals with softer bones such as those with rheumatoid arthritis, deformity or tilt will benefit the most.
Patients who have had prior deep infections, deformity that is extremely severe, or neuropathy from diabetes may not be candidates for this new technology. Such patients should still be evaluated by a surgeon, however, since individual variations may impact such an assessment and other options exist for treating ankle arthritis.
DePuy Orthopaedics, Inc., a Johnson & Johnson company, manufactures the Agility Ankle LP and chose a six member evaluation team for the prosthesis. DePuy designs, manufactures and distributes orthopaedic devices and supplies including hip, knee, extremity, trauma, orthobiologics and operating room products. The company's headquarters is in Warsaw, Indiana.
Dr. Haddad, a member of the evaluation team, is currently the only surgeon in Illinois with authorization to use the Agility Ankle LP. His colleagues on the evaluation team are from Pennsylvania, Baltimore, Minnesota and South Dakota. Later in 2007, the prosthesis will be made available to additional physicians. Dr. Haddad has used the newer technology in 15 patients since September, 2006. The Agility Ankle LP is not yet available nationally.
Dr. Haddad has been performing ankle replacement surgery since 1999 and in 2005 he was the surgeon with the third highest volume of ankle replacements in the United States. He estimates that he has performed ankle replacement surgery on at least one person in almost every state in the country, all of whom have traveled to Glenview for their procedures. Dr Haddad's experience led DePuy to choose him to participate on the evaluation team.
The Illinois Bone and Joint Institute is an orthopaedic medical practice that specializes in the diagnosis, treatment and management of injuries and diseases of the musculoskeletal system. IBJI has over 90 physicians and over 90 rehabilitation therapists at over 25 locations throughout the Chicagoland area.
