Assessment of bone condition by acoustic emission technique: A review

Abstract

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

Avalanche criticality during compression of porcine cortical bone of different ages

“…Cortical bone has also been examined by AE to monitor microdamage during fatigue, although large data scatter prohibited further data analysis [21]. Numerous biomedical applications of AE analysis demonstrate its potential as a non-invasive method to determine bone state under in vivo conditions [22]. This includes characterization of bone healing [23] and monitoring of implants [24].…”

Biomarkers for knee osteoarthritis: new technologies, new paradigms

“…In recent years there has been increasing interest in translational applications of acoustic science to inform the diagnosis and management of several different health [31][32][33][34][35][36][37][38][39] and dental conditions [40,41]. In this context, the development of techniques to measure highfrequency AE in knee joints [16][17][18][19] offers the potential to develop a biomarker reflecting the integrity of interactions between knee joint components during weightbearing movement.…”

Novel approaches to measure acoustic emissions as biomarkers for joint health assessment

“…Shrivastava, and Prakash reviewed the use of acoustic emissions for assessing bone condition [8]. Frank et al concluded that the analysis of knee joint sounds could be used for distinguishing normal from abnormal cartilage surfaces, and for classifying disorders of the joint [9].…”
