A study of 77,947 patients found that those over 80 and with low initial ADL scores benefited from holiday rehabilitation. This suggests prioritizing interventions for elderly and independent individuals can lead to better outcomes.
Researchers from UPF and 3D-Shaper Medical developed a new computational system to predict and prevent the risk of hip fracture among people with osteoporosis. The system, which simulates the functioning of hip bone tissue using 3D images and finite elements modeling, has been shown to be a robust alternative to current clinical methods.
Scientists have discovered that studying 7% of the bone mass can accurately predict whether a woman with osteoporosis will suffer a hip fracture. The new computational model has an accuracy rate of 95%, allowing for personalized treatments tailored to specific areas of need.
Researchers identified two major steps in the evolution of human bipedality, involving a shift in the growth plate and changes in bone formation. These genetic shifts, driven by genes such as SOX9 and PTH1R, fundamentally altered the pelvis geometry, enabling humans to walk upright.
A cohort study found that patients with obesity undergoing joint replacement who experienced significant weight loss after initiating anti-obesity medications had a lower risk of 5-year and 10-year revision. This suggests that safe and sustainable weight loss may improve implant survivorship in obese patients.
A $10.8 million trial will enroll 600 patients aged 60+ to determine whether a hip replacement or internal fixation surgery is better for certain types of hip fractures. The study's patient-focused approach aims to inform clinical guidelines and help patients make informed decisions about their care.
A study comparing traditional and new hip replacement stems found larger contact areas in certain femur regions with the new stems. Traditional HA stems, however, demonstrated superior long-term preservation of bone density.
Bone mineral density (BMD) and finite element analysis (FEA) reflect actual femur strength, making them effective surrogate markers for hip bone strength. These estimates predict hip fracture risks, potentially leading to shorter and less expensive clinical trials.
The Oreopithecus bambolii skeleton reveals that this late Miocene hominoid was not optimized for efficient 2-leg walking or climbing like living great apes. The species lacked key adaptations, such as pelvic stabilization and trunk stability during bipedal gait.
Research from USC and NHM found that whale pelvic bones serve a purpose and are influenced by sexual selection. The study compared the size of pelvic bones to testis size, revealing a correlation between more competitive mating environments and larger pelvic bones.
A recent study used hip bone mineral density (BMD) measurements to predict fracture risk in postmenopausal women who stopped taking bisphosphonate therapy. The findings suggest that older age and lower hip BMD at the time of discontinuation were associated with higher rates of clinical fractures.
A new study by Johns Hopkins Children's Center researchers found that most children with severe cerebral palsy have asymmetric pelvic bones, which can affect surgical procedures. The study highlights the importance of considering pelvic asymmetry in surgeries to correct scoliosis and other spine-related issues.
Researchers identify 110 million-year-old tyrannosaur hip bone from Australia, challenging the idea that tyrannosaurs only existed in the northern hemisphere. The discovery sheds new light on the group's evolutionary history and raises questions about why they evolved into giant predators like T. rex only in the north.
A landmark review of 25-year cases shows hemicorporectomy can add years and quality of life to survivors with severe pelvic bone infections. About a third of patients survived at least nine years after the procedure, which is often considered a last resort due to limited indications.
A study of 3,269 older men found that those taking loop diuretics had faster rates of hip bone mineral density decline compared to non-users. The risk was highest among continuous users, with a rate two-and-a-half times greater than non-users.
A recent study suggests that exercise is the predominant lifestyle determinant of bone strength in young women, with daily calcium intake showing little impact on adult bone mass. The research found that physical activity accounted for between 16% and 22% of variation in hip bone mineral density and bending strength.
A study of 6,044 women aged 65 and older found that those taking epilepsy drugs lost bone mass at nearly twice the rate of non-users. This increases the risk of hip fractures by 29% over five years. Researchers recommend screening for osteoporosis and counseling on calcium and vitamin D supplements.
The study found that astronauts lost bone at a rate of 0.8-0.9 percent per month, with trabecular bone loss being more significant than cortical bone loss. The researchers used three-dimensional x-ray computed tomography to quantify bone loss in the hip and estimate changes in hip bone strength.
