Bone Grown From Human Embryonic Stem Cells

May 22, 2012 By Leave a Comment

A new study by Dr. Darja Marolt and colleagues, published in early online edition of Proceedings of the National Academy of Sciences on  May 14 shows that human embryonic stem cells can be used to grow bone tissue grafts for use in research and potential therapeutic application.

The study is the first example of using bone cell progenitors derived from human embryonic stem cells to grow compact bone tissue in quantities large enough to repair bone defects.

The work is considered a significant step towards replacements of bone losse in patients with birth defects, or patients who have suffered traumatic bone loss. [Read more...]

Magnetically Controlled Growing Rods Instrumentation For Scoliosis Treatment In Children

May 21, 2012 By Leave a Comment

A study published in the Lancet journal has reported results of an early study of using magnetically controlled growing rods instrumentation for scoliosis, a novel concept that avoids future repeat surgeries.

The study has been published by Kenneth Man-Chee Cheung and colleagues on 19 April 2012, in early online publication.

Conventionally, the scoliosis is treated with placing rods to straighten the spine and lengthening them with multiple repeat surgeries as the child grows.

Magnetically controlled growing rods obviate the need for repeat surgeries. In these rods the lengthening is carried by a handheld magnetic, a procedure that can be done on outpatient basis. [Read more...]

FlexLeg To Provide Increased Mobility To People With Lower Leg Injuries

May 21, 2012 By Leave a Comment

FlexLeg is a new mobility aid created to help those with temporary lower leg injuries, such as a broken ankle. Conventionally, a patient with leg injury is allowed to walk on the crutches and cannot walk fast and walking on the uneven terrain is difficult.

FlexLeg, from a couple of mechanical engineers from Brigham Young University in Utah, seeks to make life with an injured lower leg a little less burdensome.

FlexLeg is a hands-free alternative for people with temporary lower-leg injuries to help them walk with a more natural rhythm than using crutches and also makes them able to run. [Read more...]

Nanoparticles Deliver Higher Dose of Antibiotics to Sites of Infection

May 11, 2012 By Leave a Comment

A study reported in ACS Nano journal has reported development of nanoparticles capable of delivering higher antibiotic doses to sitexs of infection.

The study has been published on web on April 3, 2012 and is reported by Aleksandar F. Radovic-Moreno and colleagues

It si a well known fact that bacteriae have remarkable capacities to develop resistance to antibiotics. Some drugs may be effective at higher doses but the side effects of the drugs prohibit from administering higher doses to the patients.

To overcome this limitation researchers at Massachusetts institute of technologyand Brigham and Women’s Hospital have developed a nanoparticle that can deliver large doses of antibiotics right to the site of bacterial infection. [Read more...]

Playing Football On Turf Results In More Injuries Than Playing On Grass

May 3, 2012 By Leave a Comment

all on turf results in 40% more knee injuries in college football players than when played on grass. This finding has been published in American Journal of Sports Medicine, online on April 5.

The study was done to analyse the tears to the anterior cruciate ligament reported in National Collegiate Athletic Association Injury Surveillance System men’s football ACL injury database from the playing seasons of 2004-2005 through 2008-2009.

The other findings of the study are the players get more injuries in the actual game and scrimmages than practice.

The authors though have recommended to confirm the finding of more injuries on turf than grass. [Read more...]

A Prosthesis With Sensory Capability – Todd Kuiken On Future Robotic Arm

January 9, 2012 By Leave a Comment

Prosthesis development has taken big strides recently. Research has shown that targeted reinnervation enhance the capabilities of prosthetic arms  to allow the amputee to “feel” temperature, texture, etc.

Todd Kuiken is the doctor/engineer behind the concept.

Here is a video where he talks about future of the prosthetic arm

Orthopedicans Reluctant To Provide Health Care To Children With Fracture

October 17, 2011 By Leave a Comment

A new research California has suggested that orthopedic surgeons are less likely to accept children with fracture for treatment than a decade ago.

The study has been published online on Oct 13 in Journal of Pediatrics was conducted by Sabatini and colleagues.

For study, 50 randomly selected orthopedic practices were contacted twice with an identical scenario to request an appointment for a fictitious child with an arm fracture. Once it was told that the child had private insurance and once with Medicaid,the government-run health insurance program.

Access to appointments on the basis of insurance was compared with rates 10 years earlier. [Read more...]

Platelet Rich Plasma Augumentation Does Not Hasten Healing Of Small and Medium Rotator Cuff Tears

January 6, 2011 By Leave a Comment

A new study  published in does not support the use of platelet rich plasma augmentation for arthroscopic rotator cuff repair. This randomized controlled trial conducted by Roberto Castricinia and colleagues, and has been published online in American Journal of Sports Medicine.

Growth factor augmentation has been proposed to boost the healing the rotator cuff after its reinsertion on the humerus and researchers wanted to assess the efficacy and safety of growth factor augmentation during rotator cuff repair. [Read more...]
