2007 Live Webcast Birmingham Hip Resurfacing Procedure

On April 17, 2007, 5pm EDT, Wake Forest University Baptist Medical Center surgeons will demonstrate a Birmingham Hip™ Resurfacing procedure on www.OR-Live.com. Approved by the Food and Drug Administration in May 2006, the Birmingham Hip Resurfacing System is designed to remove less of the patient’s bone than traditional hip replacement surgery. “This is a breakthrough in total hip surgery that allows hip replacements to be performed in young and active patients and allows them to participate in sports activities without the limitations imposed on standard total joint patients,” said Riyaz Jinnah, M.D., Professor of Orthopaedic Surgery.

Four Recurrent Periprosthetic Knee Fractures

Case Report Four Recurrent Periprosthetic Knee Fractures from Medscape Orthopaedics & Sports Medicine eJournal[TM] 2001 Arne-Lembit Kööp, MD, Andres Kööp, MD, Irja Kiisküla, MD Introduction Periprosthetic fractures of the knee are challenging for the orthopaedist, but recurrent periprosthetic fractures are even more challenging. In this case, a 61-year-old female patient with a diagnosis of gonarthrosis deformans suffered 4 ipsilateral periprosthetic fractures during the 4.5-year period following her primary total-knee arthroplasty. A detailed case report is presented here and the classification systems, risk factors, and treatment strategies for periprosthetic fractures are discussed.

Minimally Invasive Computer Assisted Total Knee Replacement

A minimally invasive computer assisted, total knee replacement surgery will be performed live over the Internet from Tampa General Hospital on April 18, 2007 at 4 p.m. ET. The procedure involves resurfacing the ends of the bones by making a small incision through which physicians place an implant that prevents bones from rubbing against each other. Because the minimally invasive procedure cuts less or no muscle, it gives the patient the potential for the fastest possible recovery.

Kenneth Gustke, M.D., Florida Orthopaedic Institute, founding member of the American Association of Hip and Knee Surgeons, will perform the procedure that will be narrated by Steven Lyons, M.D., a surgeon at the Florida Orthopaedic Institute.

Osteonecrosis of the Femoral Head

Osteonecrosis of the Femoral Head from Medscape General Medicine™ Posted 05/07/2003 Brett Levine, MS, MD, William Jaffe, MD Introduction Osteonecrosis of the femoral head (ONFH) is the end point of a variety of disease processes resulting in decreased blood flow and, ultimately, cellular death within the femoral head.[1] This debilitating disease typically affects younger patients (average age at treatment, 33-38 years old[1,2]) and results in destruction of the hip joint. Between 10,000 and 20,000 new cases of ONFH are diagnosed each year in the United States and treatment costs of these patients is estimated to be more than $1.6 billion.[3] Modern surgical technological advancements have improved outcomes for these patients. However, due to the relatively young age of onset, these patients are often subjected to multiple operative procedures during their lifetime.
