“…Fracture healing assessment is part art, part science, and somewhat subjective, so it would be helpful to have an objective tool for providing additional information over and above that provided by radiological and clinical measures [5], [22]. To this end, ultrasound has been proposed, as early as 1958, to assess fracture healing, although there is still no effective method in use [23], [24]. Simulation has recently begun to assist in this development, as, for example, in a study reported by Dodd et al [25].…”

The manner in which ultrasound interacts with bone is of key interest in therapy and diagnosis alike. These may include applications directly to bone, as, for example, in treatment to accelerate the healing of bone fractures and in assessment of bone density in osteoporosis, or indirectly in diagnostic imaging of soft tissue with interest in assessing exposure levels to nearby bone. Because of the lack of analytic solutions to virtually every "practical problem" encountered clinically, ultrasound simulation has become a widely used technique for evaluating ultrasound interactions in bone. This paper provides an overview of the use of ultrasound simulation in bone. A brief description of the mathematical model used to characterize ultrasound propagation in bone is first provided. A number of simulation examples are then presented that explain how simulation may be utilized in a variety of practical configurations. The focus of this paper in terms of examples presented is on diagnostic applications in bone, and, in particular, for assessment of osteoporosis. However, the use of simulation in other areas of interest can easily be extrapolated from the examples presented. In conclusion, this paper describes the use of ultrasound simulation in bone and demonstrates the power of computational methods for ultrasound research in general and tissue and bone applications in particular.

“…Mechanical impedance, natural frequency, vibration analysis, stress wave propagation, ultrasonic-measurements, impact response technique, electrical potential measurements and mechanical tissue response analysis are some of the techniques, which have been attempted by different investigators for the assessment of in vivo bone condition in the past [30,31,32,33,34,35,36,37,38,39,40]. However, in all these studies, the intervening soft tissues, whose quantity and quality changes with individual to individual, affected the results.…”

The paper deals with the review of acoustic emission technique in biomedical field. The re-view is done with the aim to provide an overview of the use of AE technique in biomedical field, mainly concentrated on the AE behavior of bone under different loading conditions, its depend-ence on strain rate, in osteoporosis, monitoring the fracture healing process of bone. The over-all conclusion from the review was that almost all the studies in bone indicated that the initial AE occurs only in the plastic region and just prior to yield. That means the use of AE tech-nique for clinical application cannot be consid-ered as a safe technique, but the early occur-rence of AE events from callus promises the application of AE technique for monitoring the fracture healing process. The negligible effect of soft tissues on AE response of bone prom-ises AE to become a non-invasive method for assessment of bone condition

“…The healing processes of the fractures are main clinical problem in human and animals (Barden and Brinker, 1976;De Lutio di et al, 1993;Dickens et al, 1994;Fery-Lemonier et al, 1993;Anast et al, 1958;Friedrich and Volkenstein, 1991). Considering the nonhealing hypothesis and long term healings many investigations have been performed about the case in recent decades.…”

Abstract:We would like to thank to the Faculty of Specialized Veterinary Sciences research council. Science and Research Branch of Islamic Azad University, Punak Tehran for approval and financial support to finish this project. Problems statement: The purpose of this research was to determine the biological effect of cartilage graft as a bone defect filler and osteogenetic stimulation to speed up bone healing too. Approach: Sixteen adult male New Zealand white rabbits having body weight ranged from 3.0-3.5 Kg. Under general anesthesia, a segmental full thickness bone defect of 10 mm in length was created in the middle of the right radial shaft in all rabbits. They were divided into two groups of 6 rabbits each. Group I was considered as control and the fractured site was fixed using finger bone plate with 4 screws, whereas the ear cartilage of 1×1 cm graft was used to fill the gap after fracture fixation in Group II. Rabbits in two groups were subdivided into 2 subgroups of 1 and 2 months duration with 4 rabbits in each. Radiography and two dimensional and color Doppler sonography were done before and after creating defects and on 15, 30 and 60 days to evaluate local reaction as far as new blood vessels network and callus formation are concerned. Results: On the radiographs during the whole process, bone repair in Group I was not as perfect as those in Group II samples and trace of internal callus filled the gap incompletely in 60 days in Group I, whereas in Group II internal callus almost was formed on 30 days and in addition intercortical callus was seen supporting to cover and filled the gap completely in this group. Sonographic findings confirmed the protrusion of newly formed blood vascular network in 30 days in Group I and from 15 days in Group II and remarkably increased till end of observation period. Conclusion: Cartilage graft is suitable alternative bone filler and radiography and sonography are reliable techniques to trace local reaction at proper time.
