“…[10][11][12][13] However, the restricted area of interrogation associated with strain gauges is considered to be a limitation of the technique and recently, non-destructive optical measurement methods such as Digital Image Correlation (DIC) have gained popularity because of their full-field data-rich strain measurement capability. [14][15][16] DIC is a well-established non-contact optical metrology method that extracts full-field deformation measurements of objects subjected to external loads. 17,18 It is particularly useful for measuring deformations in complex geometries with inhomogeneous material properties, like human bone, by finding spatial correspondences between different digital images.…”

Alterations in bone strain as a result of implantation may contribute towards periprosthetic bone density changes after Total Hip Arthroplasty (THA). Computational models provide full-field strain predictions in implant-bone constructs; however, these predictions should be verified using experimental models wherever possible. In the present work, finite element (FE) predictions of surface strains in intact and implanted composite femurs were verified using digital image correlation (DIC). Relationships were sought between post implantation strain states across seven defined Gruen zones (GZ) and clinically observed longer term bone density changes. Computational predictions of strain distributions in intact and implanted femurs were compared to DIC measurements in two regions of interest. Regression analyses indicated strong linear correlation between measurements and predictions (R = 0.927 intact, 0.926 implanted) with low standard error (SE = 38µε intact, 26µε implanted). Pre-to postoperative changes in measured and predicted surface strains were found to relate qualitatively to clinicallyobserved volumetric bone density changes across seven Gruen zones: marked proximal bone density loss corresponded with a 50-64% drop in surface strain, and slight distal density changes corresponded with 4-14% strain increase. These results support the use of DIC as a pre-clinical tool for predicting post implantation strain shielding, indicative of long-term bone adaptations.

Original scientific paper Experimental and numerical research of mechanical behaviour of hip replacement implant is presented. Experimental analysis was based on standard methods for testing mechanical properties and application of Digital Image Correlation (DIC) technique, while the Finite Element Method (FEM) was used for numerical simulation. A hip prosthesis extracted from a patient after revision surgery was used as the specimen. An adapter for the implant testing was constructed to enable the condition of a proximally loosened stem. During FEM analysis, a solid model was made of the assembly. An analysis of presented results indicated good agreement of experimental and numerical research.

Eksperimentalno istraživanje je bazirano na standardnim metodama ispitivanja mehaničkih svojstava i na primjeni tehnike digitalne korelacije slike, dok je metoda konačnih elemenata (MKE) primijenjena u numeričkim simulacijama. Umjetni kuk je izvađen iz pacijenta prilikom revizijske operacije kako bi se iskoristio kao uzorak za ispitvanja. Konstruiran je adapter za ispitivanje takvog uzorka kajo bi se dobili uvjeti što sličniji realnim. Za MKE analizu napravljen je model cijelog ispitivanog sklopa. Dobiveni rezultati ukazuju na dobru sukladnost eksperimentalnog i numeričkog istraživanja.Ključne riječi: digitalna korelacija slike; metoda konačnih elemenata; umjetni kuk

“…Digital image correlation (DIC) has also been used to assess surface strains experimentally. For example, Sztefek et al measured surface strain using DIC and reported that after tibial loading, the surface strains were reduced and more uniform than before loading [73], suggesting that bone responds to mechanical stimulation as a means of reducing strain.…”

Prevention of fracture through improved bone mechanical strength is of great importance given the large number of bone disease-related fractures each year, the decreased quality of life associated with fractures, and the large anticipated increase in fracture incidence over the upcoming years due to the aging population. Exercise and other forms of mechanical stimulation have been shown to increase bone mass, suggesting improved strength. However, while bone mass is a good indicator of strength, other components (such as bone quality) also contribute to bone mechanical integrity. While increased bone mass has been explored considerably using both exercise and targeted loading models, the role of mechanical stimulation in altering bone quality has been explored to a lesser degree. Understanding how to improve both the quantity and quality of bone is critical to increasing fracture resistance. Herein, we discuss quantity and quality-based improvements that have been observed using both exercise and targeted loading models of bone adaptation.
