OBJECTIVE:
Pulsed ultrasonic waves have been shown to accelerate bone healing. The aim of this study was to evaluate the effects of low-intensity pulsed ultrasound on bone healing.
STUDY DESIGN:
Thirty-two femurs from 16 skeletally mature male Wistar albino rats were used. Two defects were produced in each femur with a 3-mm-diameter trephine bur and then autogenous cortical grafts were placed in 1 defect. The animals in the experiment group received a daily 20-minute ultrasound treatment for 15 days. All animals were killed on the 18th postoperative day.
RESULTS:
Dual-energy x-ray absorptiometry values and biochemical markers in the experimental side were significantly higher than those in the control side at the early period of bone healing.
CONCLUSIONS:
Low-intensity pulsed ultrasound treatment accelerates bone healing both in bone defects and in bone defects filled with cortical autogenous block graft.
