Axial Vibration of Threaded External Fixation Pins: Detection of Pin Loosening
Kay, M. W., Roe, S. C., Stikeleather, L. F., Mahmoud, A., & Abrams, C. F., Jr. (1998, May 1). Annals of Biomedical Engineering, Vol. 26, pp. 361–368.
author keywords: vibration; external fixation pin; interface; loosening; nondestructive
MeSH headings : Animals; Bone Nails; Bone and Bones / pathology; Dogs; External Fixators; Osteolysis / diagnosis; Vibration
topics (OpenAlex): Bone fractures and treatments; Dental Implant Techniques and Outcomes; Orthopedic Surgery and Rehabilitation
TL;DR:
Frequency and quasistatic tests of dissected pin–bone structures revealed a good correlation between natural frequency and pin-bone interface stiffness, and the measurement of natural frequency was more sensitive to bone structure changes at the pin–bones interface than low-load quasi-static stiffness.
