Dental Implants: A Way to Improve Your Health and Confidence

It is unfortunate, but the rate of tooth decay and dental disease has increased in recent years. Dental implants can help you enhance your health and confidence by replacing missing teeth. They are metal posts that are surgically placed into the jawbone to replace lost or missing natural teeth. Dental...

When a child breaks a bone, it can be hard to spot on an X-ray

Q. My 12-year-old daughter was playing basketball last week, fell and banged her left elbow on the bleachers. Since she had significant pain and swelling, we brought her to urgent care. They took X-rays and said a break was not apparent but it was possible there was a fracture there anyway. My daughter was put in a splint and sling and told to see an orthopedic surgeon.

Toughening mechanisms for the attachment of architectured materials: The mechanics of the tendon enthesis

Architectured materials offer tailored mechanical properties but are limited in engineering applications due to challenges in maintaining toughness across their attachments. The enthesis connects tendon and bone, two vastly different architectured materials, and exhibits toughness across a wide range of loadings. Understanding the mechanisms by which this is achieved could inform the development of engineered attachments. Integrating experiments, simulations, and previously unexplored imaging that enabled simultaneous observation of mineralized and unmineralized tissues, we identified putative mechanisms of enthesis toughening in a mouse model and then manipulated these mechanisms via in vivo control of mineralization and architecture. Imaging uncovered a fibrous architecture within the enthesis that controls trade-offs between strength and toughness. In vivo models of pathology revealed architectural adaptations that optimize these trade-offs through cross-scale mechanisms including nanoscale protein denaturation, milliscale load-sharing, and macroscale energy absorption. Results suggest strategies for optimizing architecture for tough bimaterial attachments in medicine and engineering.

Student warns of e-moped risks after almost losing leg

A student who was badly injured in an e-moped crash in Rome has warned about the risks the machines pose after she almost lost a leg. Eleanor Young, from Nettleham, near Lincoln, suffered a double break of her right leg and a severed artery when she was collided with a Smart car while on holiday in the Italian capital in August 2020.

Bone Degeneration Therapeutics Market Growth in Future Scope 2021-2028 | Amgen, Inc., Fate Therapeutics, Inc., Bone Therapeutics SA, Juventus Therapeutics, Inc.

Bone Degeneration Therapeutics Market continues to expand with Amgen and UCB receiving the U.S. FDA approval for its osteoporosis medicine EVENITY. Bone Degeneration Therapeutics is the use of injected nutrients to promote bone growth and repair in sickle cell disease patients. Sickle Cell Disease is a hereditary blood disorder that causes the blood cells to be made primarily from a protein called Sulfate. This protein, when combined with an enzyme (Cysteine) makes a weak chain of proteins, one of which is called Sulfate. This weak sulfate chain of amino acids is what sickle cells use as their main form of fuel to move.

Nurses from Greece Bone Up on Fractures at an International Conference

ATHENS – Twenty-eight early-career nurses from Greece will have the opportunity to broaden their knowledge in the surgical treatment of fractures at an international conference taking place in Athens, Greece, November 25-26. At the conference, participants will take part in discussions and hands-on exercises on surgical technique, in addition to attending presentations.

STAT3 is critical for skeletal development and bone homeostasis by regulating osteogenesis

Skeletal deformities are typical AD-HIES manifestations, which are mainly caused by heterozygous and loss-of-function mutations in Signal transducer and activator of transcription 3 (STAT3). However, the mechanism is still unclear and the treatment strategy is limited. Herein, we reported that the mice with Stat3 deletion in osteoblasts, but not in osteoclasts, induced AD-HIES-like skeletal defects, including craniofacial malformation, osteoporosis, and spontaneous bone fracture. Mechanistic analyses revealed that STAT3 in cooperation with Msh homeobox 1(MSX1) drove osteoblast differentiation by promoting Distal-less homeobox 5(Dlx5) transcription. Furthermore, pharmacological activation of STAT3 partially rescued skeletal deformities in heterozygous knockout mice, while inhibition of STAT3 aggravated bone loss. Taken together, these data show that STAT3 is critical for modulating skeletal development and maintaining bone homeostasis through STAT3-indcued osteogenesis and suggest it may be a potential target for treatments.

Bone defect map of the true acetabulum in hip dysplasia (Crowe type II and III) based on three-dimensional image reconstruction analysis

The high hip center technique (HHC) is considered to be feasible for acetabular reconstruction in patients with DDH, but there is little in-depth study of its specific impact on Crowe type II and III DDH. The purpose of this study was to simultaneously analyze the effect of HHC on bone coverage of the cup (CC) in the acetabular reconstruction of type II and III DDH patients and to propose a map of acetabular bone defects from the perspective of the cup. Forty-nine hip CT data of 39 patients with DDH (Crowe type II and III) were collected to simulate acetabular reconstruction by cup models of different sizes (diameter 38mm"“50Â mm, 2Â mm increment) with the HHC technique. The frequency distribution was plotted by overlapping the portions of the 44Â mm cups that were not covered by the host bone. The mean CC of cups with sizes of 38Â mm, 40Â mm, 42Â mm, 44Â mm, 46Â mm, 48Â mm, and 50Â mm at the true acetabula were 77.85%, 76.71%, 75.73%, 74.56%, 73.68%, 72.51%, and 71.75%, respectively, and the maximum CC increments were 21.24%, 21.58%, 20.86%, 20.04%, 18.62%, 17.18%, and 15.42% (P"‰<"‰0.001), respectively, after the cups were elevated from the true acetabula. The bone defect map shows that 95% of type II and III DDH acetabula had posterosuperior bone defects, and approximately 60% were located outside the force line of the hip joint. Acetabular cups can meet a CC of more than 70% at the true acetabulum, and approximately 60% of Crowe type II and III DDH patients can obtain satisfactory CC at the true acetabulum by using a 44-mm cup without additional operations.

What Are Jones and Pseudo-Jones Fracture?

The metatarsals are the long bones of the foot. The fifth metatarsal base fractures are among the most common fractures of the foot. These fractures are prone to slow healing because of the restricted blood supply to the areas of the fifth metatarsal base. A Jones fracture is a transverse...

E-cigarette use may harm your bone health

While conventional cigarette smoking is an established risk factor for osteoporosis and osteoporotic fracture, the effects of electronic cigarette (e-cigarette) use on bone health have not previously been studied. In a new study from UPMC Pinnacle, researchers found that e-cigarette use was associated with a higher prevalence of fragility fractures.

Miesha Tate suffers multiple nose fractures in loss to Vieira, faces lengthy UFC medical suspension

One of the headliners from UFC Vegas 43 on Saturday night is facing an extended period away from the Octagon. Miesha Tate appears to have suffered multiple nose fractures in her unanimous decision loss to Ketlen Vieira. Tate needs clearance from an Ear, Nose and Throat (ENT) doctor to avoid the potential six-month suspension she was handed on Tuesday by the Nevada State Athletic Commission (NSAC). If she is not cleared, then ‘Cupcake’ will be on the sidelines until May of next year.
