“…In contrast to oxide ceramics ( e.g. , alumina and zirconia) that are extensively used as articulation materials in hip and knee replacements [ 15 , 16 ], Si 3 N 4 is a non-oxide ceramic that was first used for lumbar fusion by Australian investigators. They reported successful arthrodesis outcomes after 15-years follow-up [ 17 ].…”

HighlightsSpinal infections are serious maladies affecting a growing number of patients worldwide.The diagnosis and treatment of these infections are often delayed because their symptoms mimic degenerative spinal disorders.Two cases of pyogenic lumbar discitis due to Escherichia coli and Candida albicans pathogens are presented.Resolution of discitis, and successful arthrodesis without hardware, were achieved in both cases with a silicon nitride spacer.

“…Although the most popular bearing couple of the artificial hip joint is composed of HXLPE acetabular liner and a cobalt‐chromium‐molybdenum (Co‐Cr‐Mo) alloy or ceramic femoral head, the friction coefficient for the bearing surface is higher than that of human articular cartilage. This difference may be caused by hydrophobicity of the HXLPE surface . Fluid film lubrication via the hydrated layer at the uppermost superficial articular cartilage is an essential mode of smooth joint motion, and a nanometer‐scaled phospholipid layer that covers the joint cartilage surface provides hydrophilicity and serves as an effective boundary lubricant .…”

Clinical safety and wear resistance of the phospholipid polymer-grafted highly cross-linked polyethylene liner

To reduce the production of wear particles and subsequent aseptic loosening, we created a human articular cartilage-mimicked surface for a highly cross-linked polyethylene liner, whose surface grafted layer consisted of a biocompatible phospholipid polymer, poly(2-methacryloyloxyethyl phosphorylcholine). Although our previous in vitro findings showed that poly(2-methacryloyloxyethyl phosphorylcholine)-grafted particles were biologically inert and caused no subsequent bone resorptive responses, and poly(2-methacryloyloxyethyl phosphorylcholine) grafting markedly decreased wear in hip joint simulator tests, the clinical safety, and in vivo wear resistance of poly(2-methacryloyloxyethyl phosphorylcholine)-grafted highly cross-linked polyethylene liners remained open to question. Therefore, in the present study, we evaluated clinical and radiographic outcomes of poly(2-methacryloyloxyethyl phosphorylcholine)-grafted highly cross-linked polyethylene liners 5 years subsequent to total hip replacement in 68 consecutive patients. No reoperation was required for any reason, and no adverse events were associated with the implanted liners. The average Harris Hip Score increased from 38.6 preoperatively to 96.5 5 years postoperatively, and health-related quality of life, as indicated by the Short Form 36 Health Survey, improved. Radiographic analyses showed no periprosthetic osteolysis or implant migration. Between 1 and 5 years postoperatively, the mean steady-state wear rate was 0.002 mm/year, which represented a marked reduction relative to other highly cross-linked polyethylene liners, and appeared to be unaffected by patient-related or surgical factors. Although longer follow up is required, poly(2-methacryloyloxyethyl phosphorylcholine)-grafted highly cross-linked polyethylene liners improved mid-term clinical outcomes. The clinical safety and wear-resistance results are encouraging with respect to the improvement of long-term clinical outcomes with poly(2-methacryloyloxyethyl phosphorylcholine)-grafted highly cross-linked polyethylene liners. © 2016 Orthopaedic Research Society.

“…Currently, this couple has been upgraded to fourth-generation ceramics using nanoscale zirconia particles stabilized with yttrium (25%), which are dispersed in an alumina matrix (74%) together with strontium (1%) to suppress crack propagation and, thus, higher strength (Chevillotte et al, 2011). However, despite the undoubted advantages of such a friction couple compared to others, it has a significant lack associated with the high probability of total hip joint revision arthroplasty due to the fragile fracture of its ceramic elements (Filippenko, 2013;Chang, 2014;Kumar et al, 2014), mainly in the tapered connection of the head with the neck of total hip joint stem when significant dynamic loads occur.…”

There is a global tendency to rejuvenate joint diseases, and serious diseases such as arthrosis and arthritis develop in 90% of people over 55 years of age. They are accompanied by degradation of cartilage, joint deformities and persistent pain, which leads to limited mobility and a significant deterioration in the quality of life of patients. For the treatment of these diseases in the late stages, depending on the indications, various methods are used, the most radical of which are methods of joint arthroplasty and, in particular, total arthroplasty. Currently, total arthroplasty is one of the most effective and high-quality surgical operations at the relevant medical indications. However, complications may also arise after it, leading, inter alia, to the need for repeated surgical intervention. In order to minimize the likelihood of complications, the artificial joints used in total arthroplasty and the technology of their fabrication are constantly being improved, which leads to the emergence of new designs and methods for their integration with living tissues. At the same time, at the moment, the improvement of traditional designs and production technologies has almost reached the top of their art, and their further improvements can be insignificantly or are associated with the use of the most up-today technologies, allowing for friction couples with low tribological properties to provide for them high ones, for example, gradient increase hardness in the couple titanium alloy on titanium alloy. This paper presents the current state of traditional technical means and technologies for joint arthroplasty. The main attention is paid to the analysis of the latest technologies in the field of joint arthroplasty, such as osseointegration of artificial joints, the improvement of materials with the property of osteoimmunomodulation, the improvement of joint arthroplasty technologies based on the modeling of dynamic osteosynthesis, as well as the identification of possible unconventional designs of artificial joints that contribute to these technologies, predictive assessment of areas for technologies improvement.
