Low-intensity pulsed ultrasound accelerates bone maturation in distraction osteogenesis in rabbits.
We investigated the effects of low-intensity pulsed ultrasound on distraction osteogenesis in a rabbit model. Callotasis of the right tibia was performed in 70 male Japanese white rabbits using mini-external fixators. In the first part of the study in 64 animals using normal distraction (waiting period seven days; distraction rate 0.5 mm/12 hours; distraction period ten days), we evaluated the ...
متن کاملLow-intensity pulsed ultrasound accelerates osteogenesis at bone-tendon healing junction.
This study was designed to evaluate low-intensity pulsed ultrasound (LIPUS) in acceleration of mineralization and remodeling of the new bone formed at the healing interface of bone-tendon junction. Thirty-two mature New Zealand white rabbits underwent partial patellectomy and direct repair of the patellar tendon and proximal patella. Animals were then divided into LIPUS treatment group (20 min/...
متن کاملLow Intensity Pulsed Ultrasound Accelerates Bone -tendon Junction Repair
INTRODUCTION: Many trauma surgeries and reconstructive surgeries involve re-establishment of a bone-tendon (B-T) junction, such as repair of patella fractures. In case of comminuted patella fractures, partial patellectomy has become a option of surgical repair . But direct B-T junction repair is slow due to poor regenerative capability of its junctional fibrocartilage zone. Biophysical interven...
متن کاملLow-intensity pulsed ultrasound accelerates osteoblast differentiation and promotes bone formation in an osteoporosis rat model.
OBJECTIVE We examined the effects of low-intensity pulsed ultrasound (LIPUS) on cell differentiation, bone mineralized nodule formation and core-binding factor A1 (Cbfa1) expression in a normal human osteoblast (NHOst) cell line and bone formation in an osteoporosis animal model. METHODS NHOst cells were cultured in vitro in medium with or without LIPUS stimulation. The ultrasound stimulation...
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...
