“…The static bending tests revealed distinct elastic–plastic deformation behavior between both plate constructs. The titanium plates demonstrated an early functional failure by fracturing of the plate at the proximal screw hole close to the osteotomy line, while the PEEK-carbon composite plate specimens failed because of distal screw back outs 20. The PEEK-carbon composite plates resisted higher dynamic loadings and had a higher static flexural rigidity.…”

Carbon-fiber-reinforced polyetheretherketone (CFR-PEEK) has been successfully used in orthopedic implants. The aim of this systematic review is to investigate the properties, technical data, and safety of CFR-PEEK biomaterial and to evaluate its potential for new innovation in the design of articulating medical devices. A comprehensive search in PubMed and EMBASE was conducted to identify articles relevant to the outcomes of CFR-PEEK orthopedic implants. The search was also expanded by reviewing the reference sections of selected papers and references and benchmark reports provided by content experts. A total of 23 articles were included in this review. There is limited literature available assessing the performance of CFR-PEEK, specifically as an implant material for arthroplasty systems. Nevertheless, available studies strongly support CFR-PEEK as a promising and suitable material for orthopedic implants because of its biocompatibility, material characteristics, and mechanical durability. Future studies should continue to investigate CFR-PEEK’s potential benefits.

“…In the past 10 years, many research labs have developed new methods to study hip joint biomechanics including: digital image correlation (Dickinson et al, 2012, Dickinson et al, 2011), roentgen stereophotogrammetric analysis (Dy et al, 2008, Myers et al, 2011), digital variable resistance transducers (Safran et al, 2011, Smith et al, 2011), real-time contact-pressure measurement (Lee et al, 2015, Rudert et al, 2014), fluid infusion devices (Cadet et al, 2012, Dwyer et al, 2014), optical tracking motion analysis (Lopomo et al, 2010, Signorelli et al, 2013), 3D digital reconstructions combining CT scans and motion tracking (Dwyer et al, 2014, Incavo et al, 2011), combined use of in-vitro and finite element modelling (Anderson et al, 2008, Dickinson et al, 2011, Elkins et al, 2011), custom built rigs in servo-hydraulic actuators/materials testing machines (Dickinson et al, 2012, Elkins et al, 2011, Ito et al, 2009, Song et al, 2012, van Arkel et al, 2015a, van Arkel et al, 2015b) and six-degrees-of-freedom robotic load/torque actuators (Colbrunn et al, 2013, Smith et al, 2014). Such variation in testing methodology not only allows new hypotheses to be tested but also prevents systematic bias that could result from using the same methodology with the same limitations.…”

Many innovative experiments are designed to answer research questions about hip biomechanics, however many fail to define a coordinate system. This makes comparisons between studies unreliable and is an unnecessary hurdle in extrapolating experimental results to clinical reality. The aim of this study was to present a specimen mounting protocol which aligns and registers hip specimens in the International Society of Biomechanics (ISB) coordinate system, which is defined by bony landmarks that are identified by palpation of the patient׳s body. This would enable direct comparison between experimental testing and clinical gait analysis or radiographic studies. To represent the intact hip, four intact synthetic full-pelves with 8 full-length articulating femora were assembled and digitised to define the ISB coordinate system. Using our proposed protocol, pelvis specimens were bisected into left and right hemi-pelves and femora transected at the mid-shaft, and then mounted in bone pots to represent a typical experimental setup. Anatomical landmarks were re-digitised relative to mechanical features of the bone pots and the misalignment was calculated. The mean misalignment was found to be less than 1.5° flexion/extension, ab/adduction and internal/external rotation for both the pelves and femora; this equates to less than 2.5% of a normal range of hip motion. The proposed specimen mounting protocol provides a simple method to align in vitro hip specimens in the ISB coordinate system which enables improved comparison between laboratory testing and clinical studies. Engineering drawings are provided to allow others to replicate the simple fixtures used in the protocol.

“…It has been widely used in biomechanics (Dickinson et al 2012;Hokka et al 2015) and is utilized for measuring cell deformation in this study. However, the measurement accuracy of DIC is closely related to the quality of the speckle pattern (Lecompte et al 2006;Pan et al 2010), which is a serious concern for cell deformation.…”

Effect of Freezing Rate on the Onion Cell Deformation Evaluated by Digital Image Correlation

Cell deformation induced by freezing is a phenomenon that is affecting food quality. In this paper, digital image correlation (DIC) was used to investigate the effect of freezing rate on onion cell deformation. In order to improve the measurement accuracy of DIC, a micro-scale speckle pattern was formed on the onion cell surface by evenly coating CuO nanoparticles before performing a freezing test. Then, freezing tests were carried out in three different frozen conditions and DIC analysis was performed. Test results show that the cell deformation is nonhomogenous. Relatively larger deformation usually occurs in the region near the cell wall, and the deformation in the central region of a cell is usually relatively smaller. Moreover, the range of the cell deformation field decreases with an increase in freezing rate. The relationship between the cell deformation and the freezing rate shows that a relatively smaller range of cell deformation corresponds to a better preservation quality of the onion. The deformation analysis presented in this study can be used to evaluate the quality of vegetables after being frozen.
