• Vanguard MacNeal Hospital Acheives Gold Standard in Nursing Excellence.

    Vanguard MacNeal Hospital has achieved Magnet® recognition by the American Nurses Credentialing Center's (ANCC) Magnet Recognition Program®, which ensures that rigorous standards for nursing excellence are met.

    Magnet is the highest recognition an organization can receive for nursing care as established by the ANCC, a division of the American Nurses Association (ANA). This award recognizes health care organizations that provide the very best in nursing care and uphold the tradition of professional nursing practice. Of the more than 140 hospitals in the state of IL, MacNeal is proud to be one of only 33 in the state and 7 within the Chicago land area to hold this prominent designation.

  • Study shows direct correlation between linear wear of hip implants and patient activity

    German and American researchers have conducted one of the first studies indicating a direct link between patient activity and the rate of linear wear in total hip replacements using alumina heads and conventional polyethylene.

    Using univariate regression analysis, Finn and colleagues were able to assess weight, age at surgery, peak activity, medium intensity steps, high intensity steps, inclination angle and acetabular anteversion, according to the abstract. Age, weight, gender and cup position were not associated with the linear wear rate.

  • Tough gel stretches to 21 times its length, recoils, and heals itself - may pave the way to replacing damaged cartilage in human joints

    A team of experts in mechanics, materials science, and tissue engineering at Harvard have created an extremely stretchy and tough gel that may pave the way to replacing damaged cartilage in human joints.
    "Conventional hydrogels are very weak and brittle - imagine a spoon breaking through jelly," explains lead author Jeong-Yun Sun, a postdoctoral fellow at the Harvard School of Engineering and Applied Sciences (SEAS). "But because they are water-based and biocompatible, people would like to use them for some very challenging applications like artificial cartilage or spinal disks. For a gel to work in those settings, it has to be able to stretch and expand under compression and tension without breaking."

  • Pioneering plan for stem cell hip replacements

    SCOTS researchers have revealed plans to create a revolutionary new hip implant that will use the latest stem cell technology to allow patients to grow their own bone, removing the need for regular replacement surgery.

  • Minor exercise can protect premenopausal women's bones

    According to new research, premenopausal women who engage in physical activity can significantly reduce a known inhibitor of bone formation called sclerostin.

    The study, which will be published in the October issue of Endocrine Society's Journal of Clinical Endocrinology and Metabolism (JCEM), also found that physical activity improved IGF-1 levels, which have a positive impact on bone formation.

    "Physical activity training is conceptually simple, inexpensive, and can serve practical purposes including reducing the risk of low bone mass, osteoporosis, and consequently fractures. Our study found that even minor changes in physical activity were associated with clear effects on serum levels of sclerostin, IGF-1 and bone turnover markers."

  • Osteoarthritis after ACL surgery

    Your anterior cruciate ligament, or ACL, is one of four ligaments in the knee. If your ACL tears, you may need surgery. Unfortunately, many patients develop osteoarthritis after surgery, regardless of the type of surgery.

    Patients who have undergone single bundle ACL reconstruction surgery may not have a greater osteoarthritis risk than those who have undergone double bundle ACL reconstruction.

  • Low Rates of Knee Arthritis in Women

    Knee osteoarthritis is one of the main health burdens in the United States. Because of this condition, there is a need to better understand the course of disease to prevent and slow knee arthritis.

    Middle-age women develop osteoarthritis at fairly low rates. However, in women who already have the condition, symptoms are likely to get worse within 15 years.

  • Robot assistance simplifies placing patient-specific UKA prostheses in pilot study

    A new robotic device led to placement of unicompartmental knee arthroplasty implants matched to the patient's anatomy that exceeded the accuracy of placements involving traditional procedures and components, according to results of a pilot study presented at the British Orthopaedic Association Congress 2012, here.

    Preoperatively surgeons made operative plans for all these cases using input from CT scans that guided component position, orientation and selection of component size. Intraoperatively the surgeon holds the burr used to remove bone, but the robot provides haptic and visual feedback, Andrews said.

  • PCL repair surgery did not lead to growth problems in pediatric, adolescent patients

    Following failed conservative treatment, PCL repair or reconstruction is a safe and viable treatment option for pediatric and adolescent patients with multiligament or isolated PCL injuries, according to recent study results.

  • Patients with high BMI show similar improvements in patient-reported outcomes after TKA

    Researchers from the United Kingdom have reported similar improvements in patient-reported outcomes after elective total knee arthroplasty regardless of patient body mass index, according to a recent study published in the Journal of Bone & Joint Surgery.

    “Patients achieve equivalent improvements in knee function and general health irrespective of their preoperative BMI,” Baker told ORTHOPEDICS TODAY. “Obese patients gain as much benefit from knee replacement as patients with a ‘normal’ BMI, even if they do not end up at a similar postoperative level. Accordingly, we feel that the obese should not be excluded from the benefit experienced by their fellow patients with lower BMI from undergoing total knee replacement.”
