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 pole. th...

Applications of biological methods and systems found in nature to the study and design of engineering systems and modern technology are defined as Bionics. The present paper describes a bionics application of shape memory alloy in construction of orthopedic implant. The main idea of this paper is related to design modular adaptive implants for fractured bones. In order to target the efficiency ...

On 28th January, 1919, the leg was operated on and the fractured area exposed. I, found the upper end of the lower tibial fragment feebly united to the fibular fragments. The fractured surface of the upper tibial fragment was completely covered over by the tendon of the tibialis anticus, which was firmly united to it by dense fibrous tissue. A spur of bone, shown in the first plate, arched over...

Genetic susceptibility to fractures may be detectable in early childhood. We evaluated the associations between the polymorphic PvuII site of the COL1A2 gene and bone properties assessed by different modalities (dual-energy X-ray absorptiometry; peripheral quantitative computed tomography; gel coupling scanning quantitative ultrasonometry; ultrasound bone sonometry), bone turnover markers, and ...

AIM To confirm whether implanting pedicle-screw at the level of fractured vertebra increases adverse effects on fracture healing. MATERIAL AND METHODS CT follow-up was conducted for 28 patients who sustained thoracic or lumbar burst fracture and underwent posterior pedicle-screw instrumentation and reduction including implanting screws into the fractured vertebra at the same time. The time fo...

OBJECTIVE To compare grip strength and bone mineral content in the forearm in women and to test the effects on bone mineral content of short periods of exercise that stresses the skeleton. DESIGN Assessment of both wrists in 69 volunteers and of the non-fractured wrist in 30 patients followed by an exercise regimen entailing squeezing a tennis ball as hard as possible for 30 seconds each day ...
