distraction osteogenesis (do), firstly introduced to the medical world by russian scientist ilizarov for long bone lenghtening in orthopedics can be considered as an appropriate substitute in the treatment of maxillofacial deformities. natural events occuring during the repair of a fractured bone segment not only lead to the desired bone length but also prevent from the undesired disadvantages ...

A patients with atlantoaixial instability and osodontoideum underwent atlantoaixial fusion (Harms and Melcher technique) with demineralized bone matrix. But, unfortunately, the both pedicle screws in C2 were fractured within 9 weeks follow-up periods after several suspected episode of neck hyper-flexion. Fractured screws were not contact to occipital bone in several imaging studies, but it coul...

vertical root fracture (vrf) has been a great challenge in dentistry; most fractures often result in tooth extraction. inflammation of tissues around the fractured root is the main reason for tooth extraction. based on the strategic importance of some fractured teeth, treatment may be necessary and often complicated. however, performing a proper repair or even splinting the fractured segments m...

A new computer-based method for measuring periaxial rotation of healthy and fractured femurs from preoperative CT during closed femoral fracture reduction surgery is described. The method provides a comparative quantitative measure to align the distal and proximal femur fragments based on periaxial rotation. The periaxial rotation is defined in terms of patient-specific bone features. An algori...

Cathepsin K inhibitors have been demonstrated to restore bone mass in both animal model and postmenopausal osteoporotic patients. In the present study, we performed to investigate the pharmacological effect of icariin in the healing potential and biomechanical properties of femoral neck in a mice fractured model. The results showed that the mRNA and protein expression of cathepsin K was markedl...

The clavicle is the most frequently fractured bone in humans. General anesthesia with or without Regional Anesthesia (RA) used for surgeries due to its complex innervation.

OBJECTIVES The exact aetiology and pathogenesis of microdamage-induced long bone fractures remain unknown. These fractures are likely to be the result of inadequate bone remodelling in response to damage. This study aims to identify an association of osteocyte apoptosis, the presence of osteocytic osteolysis, and any alterations in sclerostin expression with a fracture of the third metacarpal (...

A 64-year-old woman, with amyloid related kidney failure (On renal dialysis) had a bone scan because of pain in the right upper femur. The 99m Tc-MDP images revealed marked hepatic uptake. In addition, there was right proximal femoral concentration of radiotracer, which corresponded to a fracture site. As an added finding, the same femor demonstrated circumferential uptake at the lower po...
