“…The results confirmed that PCD on PCD have the best tribomechanical characteristics [3]. The proper selection of materials, the manufacturing technology and application of appropriate coating on implants reduce the possibility of pseudotumor formation, apoptosis, inflammation, and allergic reactions of the body [4]. Application of anti-frictional coatings on hip implants reduces the frictional heating in hip implants and therefore, there is no degradation of the material, which leads to better stability and longer work life of the implant [5].…”

This paper presents short review of existing clinical solutions for artificial joints (knee joints, hip joints, shoulder joints, elbow joints, and spine segments). One of the main objectives in design of these implants is to minimise and eliminate friction and wear in moving elements and to provide full adhesion and cell proliferation for stable parts, such as for hip stem. Knee joint surgeries are important for young people, especially in sport, and they can be total or partial replacements. Hip joint surgeries are among the most performed procedures today, with increased number of young people undergoing it. Trabecular Metal technology, with porous structure, has emerged as the efficient approach to provide cell proliferation and adhesion of the hip stem. CoCr, Ti and stainless steel, together with polymers and ceramics are used for production of elements in hip replacement solutions. Shoulder joint replacements are very complex and require careful planning. Replacements of elbow joints are less present in comparison with other types of artificial joints. Solutions for vertebra, segments composing the spine, are the most important area of orthopedic trauma since it directly influences the quality of life in all the ways. This is important area of research that impact lives of millions humans. Beside standard production technologies and application of advanced CNC machines, 3D printing has emerged as efficient production technology offering custom design of personalised implants, very fast production with excellent quality, without significant postprocessing as required in standard technologies, such as casting or forging.

The increasing number of hip replacement surgeries in the worldwide practice causes the progressive increase in revision cases. The treatment of patients with instability of the hip implants requires the individual approach, taking into account the size of the defect, the loss of bone mass and the structural state of the bone in each case. Objective. To show the technical opportunities of the revision cementless implants in combination with 3D-modeling for the treatment of acetabulum massive defects. Methods. It was shown the clinical case of hip replacement surgery of the patient with the aseptic instability of endoprosthesis components. A 3D-model of the pelvis and femur was created on the basis of the СT scan in order to make an analysis of bone tissue defects and to select the exact size of implant components for revision surgery. Results. It was suggested a standardized methodology of the preoperative examination to make the high-tech operation easier and maximally effective. It is necessary not only to take into account the results of the X- ray analysis, but also to pay attention to all changes in the damaged segments. It was shown that the real plastic model make the work of the surgeon easier during all steps of the treatment. The opportunity to use the standard revision components for the restoration of the complex geometrically shaped bone was demonstrated with the good nearest clinical and radiological and functional results. Conclusions. The success of the revision arthroplasty depends on the carefully preoperative planning, the maximum approximation of the parameters of the artificial joint to the anatomical parameters of the patient and biomechanics of the hip join. No less important is the individual recovery program during the postoperative period.

“…One of the most commonly used Ti-alloy is Ti-6Al-4V. It occupies approximately 45% of the total industrial production of Ti-based bioimplants [74]. The Young's modulus of Ti alloys is in the range of 55-110 GPa, which is higher than that of a native bone [52].…”

“…The Young's modulus of Ti alloys is in the range of 55-110 GPa, which is higher than that of a native bone [52]. Therefore, the stress shielding effect remains an issue that can only be reduced, but currently impossible to avoid [74]. Ti and its alloys are non-toxic and inert at in vivo environment due to their corrosion resistant properties [73].…”

Materials for Orthopedic Bioimplants: Modulating Degradation and Surface Modification Using Integrated Nanomaterials

et al. 2020

View full text Add to dashboard Cite

Significant research and development in the field of biomedical implants has evoked the scope to treat a broad range of orthopedic ailments that include fracture fixation, total bone replacement, joint arthrodesis, dental screws, and others. Importantly, the success of a bioimplant depends not only upon its bulk properties, but also on its surface properties that influence its interaction with the host tissue. Various approaches of surface modification such as coating of nanomaterial have been employed to enhance antibacterial activities of a bioimplant. The modified surface facilitates directed modulation of the host cellular behavior and grafting of cell-binding peptides, extracellular matrix (ECM) proteins, and growth factors to further improve host acceptance of a bioimplant. These strategies showed promising results in orthopedics, e.g., improved bone repair and regeneration. However, the choice of materials, especially considering their degradation behavior and surface properties, plays a key role in long-term reliability and performance of bioimplants. Metallic biomaterials have evolved largely in terms of their bulk and surface properties including nano-structuring with nanomaterials to meet the requirements of new generation orthopedic bioimplants. In this review, we have discussed metals and metal alloys commonly used for manufacturing different orthopedic bioimplants and the biotic as well as abiotic factors affecting the failure and degradation of those bioimplants. The review also highlights the currently available nanomaterial-based surface modification technologies to augment the function and performance of these metallic bioimplants in a clinical setting.
