Introduction Low-intensity pulsed ultrasound (LIPUS) has been reported, by various authors, to promote bone healing. The aim of our review was to review the available literature and evaluate the effectiveness of LIPUS in the treatment of various types of complicated fracture union. Materials and methods Different search engines including MEDLINE, EMBASE and the Cochrane Library were used, and t...

OBJECTIVE To analyze the possible effects of low-intensity ultrasound on induced tibia fracture of rats in a dose commonly used in physical therapy treatments. METHODS Twenty male Wistar rats were divided into two groups with 10 animals each. In the ultrasound group (USG), the animals were submitted to bone fracture and treatment with therapeutic ultrasound (TUS). Ultrasonic parameters are: f...

The rate/temperature dependent fracture behaviour of plain and glass-filled polystyrene has been investigated over the crack speed (a) range of 10 -6 to 10 -2 m sec -1 and in the temperature (7-) range of 296 to 363 K. The Kc (a, T) relationships obtained, where Kc is the stress intensity factor at fracture, are shown to follow those given by the Williams/ Marshall relaxation crack growth model...

BACKGROUND Low-intensity pulsed ultrasonography (LIPUS) is a form of mechanical stimulation that is delivered via a special device to the fracture site for the acceleration of fracture healing. We conducted a meta-analysis to assess the effect of LIPUS for fresh fractures in adults. METHODS MEDLINE, EMBASE and the Cochrane Library searched between Jan 1980 and Nov 2016. Studies should be quas...

The risk of fractures is multifactorial and is related to the ability of bone to resist fracturing, which depends on its material and structural properties, and on the intensity, frequency and impact of trauma. Low BMD is a major determinant of bone strength and fracture risk. However, most patients with a fracture have no osteoporosis and BMD explains <50% of bone strength and fracture risk. B...
