Zimmer MIS 2-Incision Total Hip Replacement Procedure

Tue, 31 Jul 2007 05:13:25 -0400

http://www.or-live.com/zimmer/1606 Tucson, AZ – On Tuesday, December 5, at 4:30 pm (MT), Tucson Medical Center in Tucson, Arizona, will broadcast a live Zimmer MIS 2-Incision Total Hip Replacement procedure featuring the VerSys® Epoch® FullCoat Hip Prosthesis and the Trabecular Metal™ Modular Acetabular System with Longevity® Highly Crosslinked Polyethylene. The VerSys Epoch Hip Prosthesis' distinct composite stem design has a low modulus of elasticity to address concerns about proximal bone resorption resulting from stress shielding, as well as concerns about thigh pain that can result from a bending stiffness mismatch between the prosthesis and natural bone, particularly with larger stems. It was created to offer an extensively porous-coated implant in larger stem sizes without a significant increase in stem stiffness when compared to smaller sizes or proximally coated implants. The Trabecular Metal Modular Acetabular System incorporates the clinically successful benefits and ingrowth potential of Trabecular Metal material into a proven, modular implant design resulting in a versatile system that not only meets surgeon demands for initial and long-term stability, but also provides a wide variety of shell and liner options to address specific patient needs. Longevity Highly Crosslinked Polyethylene liners were designed to resist wear and to possess design-appropriate mechanical properties. This Zimmer Minimally Invasive Solutions™ (MIS) 2-Incision Hip Procedure is one of the least invasive hip replacement procedures available today. This surgical approach and the innovative instrumentation allow surgeons to confidently place the same, proven hip implants as a standard surgery through two small incisions. The potential benefits for patients of Zimmer MIS 2-Incision Hip Replacement include: Less tissue trauma Faster and less painful rehabilitation Smaller incisions and scars Shorter hospital stay; 1 to 2 days, rather than 3 to 5 days for traditional surgery Russell G. Cohen, MD, Director, Total Joint Replacement Services at Tucson Orthopaedic Institute in Tucson, AZ will perform the surgery. The webcast will be moderated by John A. Maltry, MD, Joint Replacement Specialist, also at the Tucson Orthopaedic Institute. Questions from surgeons and the general public can be sent in via email during the broadcast. The Zimmer MIS 2-Incision Hip Procedure was developed in collaboration with leading surgeons from around the world and is the culmination of their evolving experience. Dana Mears, M.D. of the University of Pittsburgh helped pioneer the Zimmer MIS 2-Incision Hip Procedure, launching an industry-wide drive in orthopaedics to make total joint replacement surgery less invasive, less painful and easier for patients to recover from. "From my personal experience, exceeding 1200 MIS 2-Incision Hip Procedures, this technique is suitable for most clinical situations. Improvements in the instrumentation and implants have greatly simplified the surgical technique and afforded excellent visualization of the hip. Typically, after one night in the hospital, a reasonably fit patient is discharged to home and rapidly resumes a fully, active lifestyle," said Mears. This program is part of an ongoing effort to provide convenient, innovative educational opportunities to orthopaedic surgeons worldwide and is intended to help orthopaedic surgeons enhance their skills to build confidence in providing the best orthopaedic care possible for their patients.

Zimmer® Gender Solutions™ High-Flex Knee Replacement

Tue, 29 May 2007 10:21:00 -0400

Philadelphia, PA – On Thursday, September 14, at 6:30 p.m. EDT, Pennsylvania Hospital in Philadelphia, PA will broadcast a live total knee replacement procedure featuring the Zimmer Gender Solutions High-Flex Knee, the first knee replacement shaped to fit a woman's anatomy. Knee replacements have long been available in many sizes, but merely using a different size for women doesn't resolve anatomical differences. Various studies show that women's knees significantly differ in shape from men's knees. Pioneering research conducted for Zimmer precisely maps out those differences and is the foundation for the design and development of the Gender Solutions Knee. When placing traditional implants, some surgeons accommodate women's differences by removing more bone or repositioning the implant during surgery, but their ability to make the implant precisely conform to the patient is limited. The Gender Solutions High-Flex Implant was designed so the surgeon can more closely match the female patient's knee anatomy. Robert E. Booth, Jr., M.D., Chief of Orthopaedic Surgery at Pennsylvania Hospital, Philadelphia, PA, will perform the surgery. The webcast will be moderated by Giles R. Scuderi, M.D., Director, Insall Scott Kelly Institute, and Assistant Clinical Professor of Orthopaedic Surgery, Albert Einstein College of Medicine, New York, NY. Questions from both surgeons and the general public can be sent in via email during the broadcast. "Mounting research indicates that a woman's knee is not simply a smaller version of a man's knee. The differences involve the bones, ligaments and tendons in the joints," said Dr. Booth. "Women can wear men's clothing and shoes, but most prefer clothing and shoes made for them. That's because women are shaped differently than men. It's the same with knees, and it makes perfect sense to design knee implants with women in mind, particularly considering that women are by far the majority of the knee replacement patient population." Nearly two-thirds of the more than 400,000 annual knee replacement patients are women, according to the National Center for Health Statistics, and the numbers continue to increase each year. Research shows that while both women and men vastly underuse knee replacement, women are three times less likely than men to undergo the procedure, although they suffer from more knee pain and resulting disability. "Less invasive procedures are helping patients get back to enjoying their lives faster than ever before. Now that we have a knee shaped to fit women's anatomy, we expect far more women will want to consider knee replacement," said Dr. Booth. The Gender Solutions High-Flex Knee, the first of several gender innovations to come from Zimmer, is based on the company's more than 20 years of clinical success with total knee implants. Further, it can be placed using Zimmer Minimally Invasive Solutions ™ (MIS ™) Procedures, which typically offer smaller scars, shorter hospitalization and quicker rehabilitation and recovery; and safely accommodates high flexion (up to 155 degrees), which is necessary for many activities, such as climbing stairs, sitting in a chair, gardening and golfing. "Even though most women are happy with their results after joint replacement, some still have residual pain in the front of the knee around the kneecap, or say their artificial knee just doesn't feel or move the way their own knee did when it was healthy," Dr. Booth said. "Knee implants have been functioning very well for men and women, but we want to meet women's unique needs by making knee replacements that feel, fit and function even better. The Gender Solutions Knee is the best of both worlds. It's based on the NexGen® Knee, a highly successful implant with great mechanics and 10 years of clinical success. Only the shape is different, to make it feel more natural." The knee joint is composed of three bones: the end of the femur (thighbone), the top of the tibia (shinbone) and the patella (kneecap), which are all held together by tendons and ligaments and cushioned by cartilage. Knees can become painful, due to arthritis, injury and infection, which cause deterioration of the cartilage. When the cartilage is gone, the bones of the knee grind against each other, wearing away and typically causing severe pain. Total knee replacement involves removing the portion of bone that is damaged and resurfacing the knee with metal and plastic implants. This program is part of an ongoing effort to provide convenient, innovative educational opportunities to orthopaedic surgeons worldwide and is intended to help orthopaedic surgeons enhance their skills to build confidence in providing the best orthopaedic care possible for their patients.

Minimally Invasive Treatment of Hydrocephalus

Fri, 16 Jan 2009 19:38:18 -0500

http://www.or-live.com/NYP/2553 The typical treatment for the life-threatening condition of hydrocephalus has been revolutionized with advanced minimally invasive endoscopic approaches. Standard practice for children or adults with "water on the brain" or hydrocephalus, has been to insert a shunt, a tube-like structure from inside the brain to the abdominal compartment. These devices, although very effective, are known to carry a substantial life-long risk from problems including infection and blockage. With the development of small caliber endoscopes, minimally invasive techniques are now possible in the brain. One procedure that has gained wide spread appeal replaces the need for placing shunts in patients with hydrocephalus. This minimally invasive procedure, called endoscopic third ventriculostomy (ETV), involves making a small 3-4 mm communication between the third ventricle and the subarachnoid space. The procedure can be done is as little as 15 minutes through a small incision behind the hairline. The majority of patients stay in the hospital for only 1 night. Because there is no implanted device there is no risk of shunt infection or mechanical malfunction. In the ensuing OR Live segment a young child with hydrocephalus is treated with ETV. You will meet the child and his family, listen to a detailed discussion regarding the treatment and how ETV compares with shunting, hear about the potential risks of ETV, and learn which patients are candidates for this exciting and newest available treatment for hydrocephalus. Additionally, you will actually witness this minimally invasive surgery as an observer in the operating room and through the lens of the endoscope within the brain.

Anterior Hip Replacement Surgery

Thu, 28 Feb 2008 16:59:46 -0500

http://www.or-live.com/prohealthcare/2189 Hip Replacement: – ProHealth Care will continue its educational Web cast series with the live online broadcast of an anterior hip replacement surgery at Oconomowoc Memorial Hospital on Wednesday, March 26, at noon. This will be the fourth in a series of Web casts that offer patients and consumers a first-hand look at both routine and state-of-the-art surgeries occurring at ProHealth Care hospitals. Matthew Bong, MD, orthopedic surgeon, will perform the anterior hip replacement surgery, and Scott Schneider, MD, orthopedic surgeon, will moderate. Viewers will have the opportunity to send questions directly to the operating room during the surgery. Anterior hip replacement is one of the newest procedures available to ProHealth Care Orthopedic Center patients needing hip replacement surgery. Oconomowoc Memorial Hospital was the first in the metro-Milwaukee area to offer this minimally invasive surgery using the HANA table. The special operating table allows the surgeon to more effectively move the leg during surgery to best position the hip socket, ball and femur insert for proper fit. The HANA table also allows the surgeon to take X-rays during the procedure to ensure precise fit and placement of all components. "Most patients who are candidates for traditional hip replacement surgery are also candidates for the anterior procedure," Dr. Bong says. Patients benefit from the anterior approach to hip replacement in a number of ways: Accelerated recovery time. Fewer restrictions during recovery. Patients can often more freely bend their hip and bear their full weight immediately or very soon after surgery. Possible reduced scarring. The anterior approach allows for one relatively small incision. Less discomfort during the recovery period. ProHealth Care has partnered with surgical broadcast leader OR-Live out of West Hartford, Connecticut, to produce this live event. For more information, a preview of the event, interviews with our surgeons, and to access replays of previous ProHealth Care Web casts, including a knee replacement, brain surgery and robotic prostatectomy, visit www.prohealthcare.org/OR.

Robot - Assisted Heart Bypass with Cardiac Catheterization

Sun, 15 Jul 2007 00:41:14 -0400

http://www.or-live.com/umm/1713 On February 28, 2007, at 4 PM EST watch the premiere showing of a very unique surgical webcast from the University of Maryland Heart Center in Baltimore. See for yourself an operation called the HYBRID. This is an innovative approach to double or triple vessel coronary artery disease that combines minimally-invasive, robotic coronary artery bypass surgery with stented angioplasty, performed in just one operation. The University of Maryland Medical Center is among the first hospitals in the U.S. to offer this combined surgery, and is now the only Medical Center to offer this surgery with the use of robotic technology. Cardiac surgeon, Dr. Robert Poston, an assistant professor of surgery at the University of Maryland School of Medicine, with the assistance of Dr. Charles Drummond, a clinical instructor at the University of Maryland School of Medicine, will use the daVinci-S surgical robot to harvest the left internal mammary artery, which will then be used to bypass the blockages in the heart. Unlike traditional open surgery, there is no large incision made during this operation. Several tiny incisions, which measure smaller than the diameter of a dime, are made between the ribs so that the robotic instruments can be used inside the chest cavity. While sitting at a computer console outside the actual operating room, Dr. Poston looks through lenses that provide a three-dimensional and highly magnified view of the inside of the body. He then uses wristed instruments to make very precise movements in the chest wall. Dr. Poston will harvest the left mammary artery and then through a two and half-inch incision in the chest, Dr. Poston will redirect one end of the artery to the heart surface and hand-sew the artery beyond the blockage, therefore increasing blood flow to the heart. Once this bypass portion of the surgery is complete, Dr. David Zimrin, an assistant professor of medicine and director of cardiac catheterization, will perform angioplasty to restore normal blood flow in the remaining blocked arteries. The hybrid takes place in an operating room that is both a fully equipped surgical suite and a state-of-the-art cardiac catheterization laboratory. This combined OR presents a tremendous advantage, because if for some reason doctors are unable to get a satisfactory result from the angioplasty side, they can convert to an open bypass operation. The patient won't have to be moved to another room because they will already be in a fully-equipped operating room. There are many clear advantages to the patients who undergo the hybrid. It is convenient and less stressful to have bypass surgery and stenting performed at the same time and not two separate days. During this approach, the heart remains beating throughout. Because the heart-lung machine is never used to maintain circulation, it is safer and there are fewer side effects. Also, since all incisions are very small, the rate of recovery is much faster and patients can usually go home in two days. Ideal candidates for the hybrid procedure have a blockage in a major vessel called the left anterior descending (LAD) artery, which supplies 60 percent of the blood to the heart, as well as blockages in non-LAD arteries that can be treated with a stent.

Minimally Invasive Colon Surgery

Tue, 31 Jul 2007 13:55:28 -0400

http://www.or-live.com/duluthclinic/1754 St. Mary's Medical Center in Duluth, MN, plans to broadcast a minimally invasive colon surgery, live on the Internet. The webcast is slated for Wednesday, Jan. 24, 2007, at 6:30 p.m. CST. The public will be able to view a laparoscopic hemicolectomy, the removal of part of the colon through a small incision. Duluth Clinic colorectal surgeon Melissa Najarian, MD, will perform the procedure. Duluth Clinic surgeon Thomas Wiig, MD will help explain the surgery and answer questions e-mailed by viewers. Computer users must have high-speed Internet service and the Real Player program downloaded on their system. During a typical surgery, Dr. Najarian removes a section of colon about eight inches long. In many cases, Dr. Najarian operates on patients who have colon cancer or colon polyps. A patient suffering from Crohn's disease or diverticulitis could also be a candidate for the procedure. Because this surgery is done laparoscopically, Dr. Najarian makes an incision about two inches in length, along with three or four incisions that are less than half an inch. She inserts a camera and her tools through these small cuts to perform the surgery. An open procedure of this type would likely require an eight-inch incision. When the minimally invasive procedure is appropriate for a patient's individual situation, this technique can lead to quicker healing. "They have less pain and that speeds up the recovery as well," Dr. Najarian notes. As a specialist in colorectal surgery, Dr. Najarian has honed her skills in laparoscopic procedures. "It takes more training," she says. The operating room staff must also have extra training and be comfortable using the high-tech equipment that makes this type of procedure possible. Laparoscopic techniques are used in many surgeries at St. Mary's, including the removal of the appendix, gall bladder and spleen, along with weight loss surgery and hernia repairs. Dr. Najarian says she's excited to take part in a live surgical webcast. "It will really benefit patients," she says. "I don't think people always understand what's going on with their insides." She's also hoping to use the webcast as an opportunity to remind patients about the importance of colon screenings. "If everyone had regular screenings, we might not have to do this surgery," she explains. This will be the second live webcast from an operating room at St. Mary's Medical Center, which is part of SMDC Health System. The first live broadcast here set records for the number of people viewing a live surgery on the Internet. That webcast, which featured a knee replacement surgery, can still be viewed by going to www.duluthclinic.org

Brain Tumor Resection

Tue, 31 Jul 2007 13:55:33 -0400

http://www.or-live.com/texashealth/1666 Dallas, Texas - On November 30, 2006 neurosurgeons on the medical staff of Presbyterian Hospital of Dallas(PHD) will perform in a live web cast, a brain tumor resection case within the hospital's new Nancy B. Hamon intra-operative magnetic resonance imaging (MRI) neurosurgical suite. J. Michael Desaloms, M.D. and Richard L. Weiner, M.D. will perform the surgery. The state-of-the-art operating room, dedicated to precision and real-time imaging during brain surgery, is among the first of its kind in the world. On August 31, 2006, Dr. Desaloms performed the first U.S. surgical case using BrainSUITE technology in this new operating room. This breakthrough use of advanced computerized equipment provides neurosurgeons access to all-important clinical data about a patient's brain condition during surgery. The increased level of information — converging in real time — can assist in improving the precision and accuracy of procedures, which may reduce the need for repeat surgeries.

Dramatic Advance in Parathyroidectomy

Wed, 01 Apr 2009 12:53:21 -0400

http://www.or-live.com/christianacare/2349 NEWARK, DE - Hyperparathyroidism is a common disease that can cause depression or chronic fatigue, kidney stones and even osteoporosis. It is also a disease for which a focused surgical treatment—called a parathyroidectomy—has dramatic, almost instant results. On April 30 at 5 p.m. EDT, Christiana Care Health System will webcast an ORLive minimally invasive parathyroidectomy performed by Dr. Raafat Abdel-Misih. This procedure not only removes the enlarged parathyroid gland that is the cause of the disease; it incorporates a laboratory procedure that allows the surgeon to verify that the operation was successful while the patient is still in the operating room, which makes the entire process easier on the patient. "By measuring the patient’s hormone level immediately after the surgery, we know almost instantly that we have successfully removed all of the growth that was causing the symptoms," said Dr. Abdel-Misih. "This prevents a situation where we would have to bring the patient back into the operating room and redo the procedure." Most patients are able to go home within hours after the surgery, and the results are often dramatic. "Groans, stones, moans and bones. That's what we traditionally teach medical students when diagnosing hyperparathyroidism," said Dr. Michael Rhodes, Chair of Christiana Care's Department of Surgery and narrator for the live webcast. "Abdominal groans may occur from nausea and pain resulting from ulcers or pancreatitis, stones refer to the prevalence of kidney stones, occasional psychiatric moans may result from fatigue and depression, and the bones may be affected by osteoporosis. Often, patients who undergo the surgery discover within hours, days or weeks that their mood and energy level are greatly improved." Hyperparathyroidism is the result of a tumor on one or more of the parathyroid glands, which are four tiny glands in the front of the neck. They produce a hormone known as PTH (parathyroid hormone), which regulates calcium levels in the blood. When one of the glands becomes enlarged, it causes the body to move calcium out of the bones and into the bloodstream. Patients seldom realize that they have the disease, but it is typically detected in a routine blood test. Viewers will be able to e-mail live questions to the doctors during the procedure and receive answers in real time. This will be the first of several ORLive presentations from Christiana Care Health System.
