Orthopaedics: Structural support

In the 1960s, a remarkable substance called etidronate came into use as an effective treatment for bone problems. Etidronate is a bisphosphonate, a class of material known since the late 1800s to inhibit metal crystallization and corrosion, a feature that led to its wide usage in the oil and gas industry. More than 60 years later, researchers at Proctor & Gamble found that bisphosphonates are just as effective at preventing the destruction of bones in the human body as they are at stopping metal degradation. Proctor & Gamble began marketing etidronate as Didronel, and it soon became a standard treatment for muscle calcification, Paget's disease of bone, heterotropic ossification (in which bone is formed outside the skeleton), menopausal osteoporosis and, finally, bone degradation in multiple myelomaNature 480, S56–S57; (15 December 2011) PDF

Effects of in vivo mechanical loading on large bone defect regeneration.

Fracture healing is highly sensitive to mechanical conditions; however, the effects of mechanical loading on large bone defect regeneration have not been evaluated. In this study, we investigated the effects of functional loading on repair of critically sized segmental bone defects. Boerckel JD, Kolambkar YM, Stevens HY, Lin AS, Dupont KM, Guldberg RE. J Orthop Res. 2011 Dec 14.

Does team training save lives? A new science gives it a rigorous evaluation

Whether the task is flying a plane, fighting a battle, or caring for a patient, good teamwork is crucial to getting it done right. That's why team-building and training courses are big business in the U.S., and have been for decades. But lately something has changed: "There's a demand for evaluations—an emphasis on showing that team training makes a difference in safety, decision-making, communication, clinical outcomes—you name the ultimate criteria the industry has," says Eduardo Salas, an organizational psychologist at the University of Central Florida.

The answer to that demand is the subject of a new article in Current Directions in Psychological Science, a publication of the Association for Psychological Science. Eurekalert!

A case series featuring extremely short below-knee stumps.

Lower limb amputations should be evaluated carefully, especially with regard to the possibility of preserving the knee joint to enable a more physiological gait and lower energy consumption. Below-knee amputations were performed immediately below the tibial tuberosity with maintenance of the insertion of the patellar tendon, resulting in very short, but functional stumps. This case study examined whether very short below-knee stumps allow a more functional gait, as compared to more proximal amputations. Carvalho JA, Mongon MD, Belangero WD, Livani B. Prosthet Orthot Int. 2011 Dec 14.

Now in Part 2, we’ll look at Papers, Sente, and PDF Expert – and name our pick for best PDF management app for healthcare professionals. iMedicalApps

Team designs a bandage that spurs, guides blood vessel growth

Researchers have developed a bandage that stimulates and directs blood vessel growth on the surface of a wound. The bandage, called a "microvascular stamp," contains living cells that deliver growth factors to damaged tissues in a defined pattern. After a week, the pattern of the stamp "is written in blood vessels," the researchers report. A paper describing the new approach will appear as the January 2012 cover article of the journal Advanced Materials.

"Any kind of tissue you want to rebuild, including bone, muscle or skin, is highly vascularized," said University of Illinois chemical and biomolecular engineering professor Hyunjoon Kong, a co-principal investigator on the study with electrical and computer engineering professor Rashid Bashir. "But one of the big challenges in recreating vascular networks is how we can control the growth and spacing of new blood vessels." Eurekalert!

University of Maryland finds restricting post-surgery blood transfusion is safe for some hip patients

More than half of the older, anemic patients in a New England Journal of Medicine study did not need blood transfusions as they recovered from hip surgery, according to new research co-authored by University of Maryland School of Medicine scientists. The findings could immediately change the way such patients are treated.

Doctors have long assumed that transfusions strengthen patients weakened by anemia, improving their chances at recovery from surgery after hip fracture. But the North American study of more than 2,000 patients found no significant difference in rate of recovery between patients who received transfusions at a moderate level of anemia and those who did not receive transfusions until their anemia was more advanced.

Review of Vue Motion Medical Image Viewer, the first HTML5 based and FDA approved radiology viewer

As we recently reported, Carestream has received FDA clearance for its Vue Motion HTML5 based medical image viewer. This is a major step forward in ensuring cross-platform availability, theoretically making it accessible from any device that has a web browser.

Although other vendors have released apps for the iPad and other tablets to access their PACS systems, Vue Motion is the first web-based viewer that we know of that can be accessed from tablets without installing additional software. iMedicalapps

Patients at risk of knee joint complications when new technology is used

Orthopaedic surgeons face a steep learning curve to get used to new prostheses, and the instruments and methods that go with them, before new total knee replacement procedures are as safe and effective as conventional methods. Patients who undergo the first 15 operations using a new device in a hospital are 48 percent more likely to need early revision surgery, than patients undergoing an operation to fit a prosthesis previously used in the hospital. The work by Mikko Peltola from the National Institute for Health and Welfare in Finland, and colleagues, is published online in Springer's journal, Clinical Orthopaedics and Related Research.

It's all in the wrapping: Mimicking periosteum to heal traumatic bone injury

Tested on sheep in Switzerland, the surgical elastic "implant device," essentially a wrapping that mimics bone's own sock-like sheath called periosteum, delivered stem cells, growth factors and other natural components of the periosteum to heal a defect that would not heal on its own if left untreated. In experimental groups exhibiting best outcomes, a dense network of new bone filled the defect, from the surgical elastic wrapping on the outside towards the steel intramedullary nail that stabilized the bone on the inside, bridging old with new bone.

Melissa Knothe Tate, a joint professor of biomedical engineering and mechanical & aerospace engineering at Case Western Reserve University; Ulf Knothe, an orthopedic surgeon at the Cleveland Clinic, as well as Hana Chang and Shannon Moore, graduate students in Knothe Tate's lab, report their work in today's issue of PLoS ONE.

Helical plate fixation for treatment of comminuted fractures of the proximal and middle one-third of the humerus.

When an operative treatment is indicated for comminuted fractures of the proximal and middle one-third of the humerus, plate fixation is one of the better options. However, a long plate must be applied from the lateral aspect of the greater tuberosity to the shaft of the humerus, which requires dissection of the deltoid muscle insertion.

Regenerative Tendon and Ligament Healing: Opportunities with Recombinant Human Platelet-Derived Growth Factor BB-homodimer (rhPDGF-BB).

Intrinsic tendon healing in response to injury is a reparative process which often results in formation of scar tissue with functional and mechanical properties inferior to those of the native tendon. Development of therapies which can promote regenerative, rather than reparative, healing hold the promise of improving patient recovery from tendon and ligament injuries by producing tissue that is morphologically and functionally equivalent to the native tissue. One therapeutic approach that has been a frequent topic of investigation in the preclinical literature is the use of recombinant human platelet-derived growth factor-BB (rhPDGF-BB) to augment tendon and ligament repair. Hee CK, Dines JS, Solchaga LA, Shah V, Hollinger JO. Tissue Eng Part B Rev. 2011 Dec 6.
