this study was carried out from October 1993 through November 1995(26 months).during this period 3472 patients(2743 male and 729 female) with long bone and/or pelvic fracture were admitted in different wards of Shahid Bahonar hospital of Kerman.based on the Gurd criteria,25 of these patients (24 male,1 female) were suffering from fat embolism sundrome(FES).incidence of FES in this study was ...

The healing of a fracture is one of the most remarkable of all the repair processes in the body since it results, not in a scar, but in the actual reconstitution of the injured tissue in something very like its original form. It is not to be expected therefore that the mechanisms controlling such a process will be easily elucidated and indeed they involve problems of cellular homeostasis which ...

Computational Methods of Ultrasound Wave Propagation in Healing Long Bones D. I. Fotiadis1 Summary Quantitative ultrasound has attracted significant interest in the evaluation of bone fracture healing. Animal and clinical studies have demonstrated that the propagation velocity across fractured bones can be used as an indicator of healing. Researchers have recently employed computational methods...

Between 2005 and 2009, 87 children (aged between 3-15 years) with multiple and combined trauma were examined and operated, using the apparatus of external fixation. In 68 (78.2%) of patients, stabilization of bone fragments was performed for the first 2 days of the accident. The study showed that using the early osteosynthesis for treatment of long bone fractures in multiple and combined trauma...

We compared the results of primary ultrasonographic examination of 163 children with 224 suspected fractures with the subsequent radiological findings. The aim was to assess the value of ultrasound in the diagnosis of fractures in children. We found a good correlation for fractures of the long bones of the upper and lower limbs. Ultrasound was most reliable for the detection of simple femoral a...

This thesis reports several methods for automated analysis and interpretation of bone X-ray images. Automatic segmentation of the bone part in a digital X-ray image is a challenging problem because of its low contrast against the surrounding flesh. In this thesis, we propose a fully automated X-ray image segmentation technique, which is based on a variant of entropy measure of the image. We hav...

Understanding the etiology of skeletal fragility during growth is critical for the development of treatments and prevention strategies aimed at reducing the burden of childhood fractures. Thus we evaluated the relationship between prior fracture and bone parameters in young girls. Data from 465 girls aged 8 to 13 years from the Jump-In: Building Better Bones study were analyzed. Bone parameters...

Bisphosphonates are potent inhibitors of bone resorption and widely used to treat osteoporosis. Extensive studies have shown that therapy with bisphosphonates improves bone density and decreases fracture risk. However, concerns have been raised about potential over-suppression of bone turnover during long-term use of bisphosphonates, resulting in increased susceptibility to and delayed healing ...

Bisphosphonate is notable for the treatment of osteoporosis in the world. But recently if Bisphosphonate is taken for a long time, it causes an insufficiency fracture by suppression of bone turn-over and it is reported rarely on femur neck. Here we report a case of insufficiency fracture on ipsilateral femur neck in woman treated with long term Bisphosphonate therapy.

Fatigue fractures of the femoral component of cementless hip prostheses are rare occurrences at present, but may become more widespread in the future as the demand increases for porous coated cementless hip arthroplasty in young, active, and heavy patients. Whereas the fatigue fracture of high strength forged alloys is unlikely, a risk of fatigue fracture may exist for sintered porous coated st...
