The success of total hip arthroplasty depends on the experience surgeon, and one ways surgeon currently determines final implant insertion depth is to listen change in audible pitch hammering sound. We investigated use acoustic vibration emissions as a novel method for quality assessment. A non-invasive contact microphone-based measurement system estimation, fixation fracture detection was developed using simplified vitro bone/implant (n=5). 2583 audio recordings were analysed obtain energy spectral density functions. Out four main resonant peaks under conditions, broach statistically correlates increasing 3rd 4th peak frequencies. Degree also observed higher goodness fit (0.26-0.78 vs. 0.12-0.51 between two sizes, latter undersized). Finally, however, moment could not be predicted. cadaver situ pilot study suggests comparable frequencies same order magnitudes with bone model. Further understanding signal patterns are needed an early warning diagnostic imminent fractures, damage, improving accuracy future procedures.
