low intensity pulsed ultrasound treatment increases rabbit radial fracture healing

چکیده
in order to study the effect of ultrasound (us) on bone healing, a complete transverse fracture was made in the right radius of adult male rabbits by a cutter. 52 rabbits were used: group i. control (n= 17): group 2. test (n:=: 15): group 3, intact (n= i) and group 4 (n= 12) who were examined only for evaluation of the cutter effects in detail. 7 animals were operated with a gigli saw. the test group received us treatment at 0.5 w /cm2• i mhz, 2 msec on-8 msec off for 10 min/day, from the day after surgery until complete fusion was observed. radiological studies indicated that mean healing duration and rate of healing was significantly more in the test group than in controls. histological evaluation showed the presence of ossified callus at week 3 in the test group. but in controls fibrous callus was still seen at week 5 after surgery. bone mineral analyses by stereoelectron microscope showed that the mineral component of the treated bone revert to normal, similar to the composition of intact bone. and sooner than that of the control. however, our results revealed no deleterious effects of us on treated and untreated ipsilateral and contralateral bones during the experiment or one month after complete fusion of the bones, at which time us was terminated

Low-intensity pulsed ultrasound in the treatment for fracture
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...
متن کاملTHE BEST DURATION OF LOW INTENSITY PULSED ULTRASOUND FOR ACCELERATING FRACTURED-RADIAL BONE REPAIR
We have already shown that low intensity pulsed ultrasonic treatment increases rabbit radial fracture healing. The present experiment was undertaken to find out the best duration for treatment. A complete transverse fracture was made in the right radial bones of21 adult male rabbits by a Stanley knife. The animals were divided into 4 groups: group 1, control groups 2, 3, and 4, experimental...
متن کاملOsteoporotic Bone showed Enhanced Fracture Healing Response with Low Intensity Pulsed Ultrasound
Introduction: Most fractures in elderly are fragility fractures occurring in osteoporotic bones. Delayed in treatment may cause morbidity and mortality with many complications and social burdens. Our previous clinical study had shown that the use of low intensity pulsed ultrasound (LIPUS) could provide a beneficial effect on complex fracture. This promising efficacy was further consolidated thr...
متن کاملAcceleration of tibial fracture-healing by non-invasive, low-intensity pulsed ultrasound.
Sixty-seven closed or grade-I open fractures of the tibial shaft were examined in a prospective, randomized, double-blind evaluation of use of a new ultrasound stimulating device as an adjunct to conventional treatment with a cast. Thirty-three fractures were treated with the active device and thirty-four, with a placebo control device. At the end of the treatment, there was a statistically sig...
