1. The mean attenuation coefficients of trabecular and cortical bone in the radius were measured in 32 female patients with fractured proximal femur, and in 28 age-matched female controls, with a special-purpose computed tomography-scanner. 2. The largest difference between the two groups was in the mean attenuation coefficients for trabecular bone in the distal radius. The mean value for fract...
The bone diagnostic instrument (BDI) is being developed with the long-term goal of providing a way for researchers and clinicians to measure bone material properties of human bone in vivo. Such measurements could contribute to the overall assessment of bone fragility in the future. Here, we describe an improved BDI, the Osteoprobe IItrade mark. In the Osteoprobe IItrade mark, the probe assembly...
OBJECTIVES Oral and maxillofacial defects often require bone grafts to restore missing tissues. Well-recognized donor sites include the anterior and posterior iliac crest, rib, and intercalvarial diploic bone. The proximal tibia has also been explored as an alternative donor site. The use of the tibia for bone graft has many benefits, such as procedural ease, adequate volume of cancellous and c...
The internal fixing materials made from shape-memory alloys (SMAs) have recently been reported for long bone fracture. We present a new internal fixation technique using a cylindrical SMAs implant in a rat femoral fracture healing. The implant was designed in a shape to circumferentially fix the fractured bone using resilient SMA claws. To evaluate the fixing ability of the implant, three-point...
The objective of this study was to assess bone density measurements for analysis of repairing fractures in rats using direct digital radiography under Dexamethasone effects. Thirty (30) young adult male Wistar rats were used, with an average weight of 200g, which were submitted to general anesthetics by ethyl ether. One rib of each animal was fractured by surgical technique. The rats were divid...
BACKGROUND Several techniques have been designed to treat fifth metacarpal fractures reported to be effective. However, these methods cannot be easily applied to the fourth metacarpal due to its central anatomical position. In this study, we sought to analyze the functional outcomes of patients who underwent transverse pinning for a fourth metacarpal bone fracture. METHODS A total of 21 patie...
Human bones are the hard organs that protect vital such as heart, lungs, and other internal organs. Fractures of a prevalent issue among humans. Bone fractures may develop from an accident or another circumstance when there is great pressure on bones. It be difficult time-consuming to determine site fracture in patient who suffering discomfort. The manual examination during radiological interpr...
Monoclonal gammopathies of undetermined significance (MGUS) have been shown to be associated with an increased risk of fractures. This study describes prospectively the bone status of MGUS patients and determines the factors associated with vertebral fracture. We included prospectively 201 patients with MGUS, incidentally discovered, and with no known history of osteoporosis: mean age 66.6±12.5...
Age related bone diseases such as osteoporosis are considered among the main causes of reduced bone mechanical stability and bone fractures. In order to restore both biological and mechanical function of diseased/fractured bones, novel bioactive scaffolds that mimic the bone structure are constantly under development in tissue engineering applications. Among the possible candidates, chitosan-ba...
A man with Paget's disease of bone was admitted with a fractured neck of femur. On admission he was normocalcaemic, but with immobilization he rapidly became hypercalcaemic, despite a normal diet and no medication. The hypercalcaemia responded to calcitonin. Although hypercalcaemia is often quoted as complicating the immobilization of such patients, well documented uncomplicated cases have rare...
