“…The femoral implants used in this study had a double‐tapered wedge shape and mimicked those used in cemented THAs in humans, with excellent mid‐term clinical results . The results of the present study indicated that the bone‐bonding ability of TBC was superior to that of commercial PBC under weight‐bearing conditions.…”

We developed a composite cement containing lowcontent bioactive titania fillers dispersed among specific polymethylmethacrylate (PMMA) polymers and investigated the mechanical properties and bioactivity of this titania bone cement (TBC) under load-bearing conditions in cemented total hip arthroplasty (THA) in adult female beagles. TBC and PMMA bone cement (PBC) were compared using custom-made prostheses. The dogs were killed 1, 3, 6, and 12 months postoperatively. The acetabulum was harvested to evaluate the osteoconductivity of the cement, whereas the femur was harvested for the pushout test and histological analyses. The compressive strength of TBC was significantly higher than that of PBC (p < 0.001), whereas the flexural and tensile strengths, as well as fracture toughness, were equivalent. The bonding strength values for TBC and PBC were 72.9 and 58.0 N/mm at 1 month, 69.4 and 57.2 N/mm at 3 months, 106.1 and 85.0 N/mm at 6 months, and 114.3 and 100.7 N/mm at 12 months, respectively. Histologically, TBC was in direct contact with bone without intervening with fibrous tissue over larger areas and newly formed bone was observed along the cement. The excellent mechanical properties and apparent bioactivity of this novel bone cement indicate its potential utility in clinical practice.

“…Results clearly show that titanium arthroprostheses have a high survival rate up to about 10 years of follow-up, but then show a steep decrease between 10 and 30 years. These devices are extremely reliable, and the failure is prevalently caused by patient-associated conditions, such as advanced age [ 372 , 373 , 374 , 375 , 376 , 377 , 378 , 379 , 380 , 381 , 382 , 383 , 384 , 385 , 386 , 387 , 388 ]. Most late failures are caused by osteoporosis and other risk factors that were not present (or not as advanced) at the time of implantation and, overall, mechanical failures and infections only account for about 15% of the total [ 389 ].…”

Titanium alloys have emerged as the most successful metallic material to ever be applied in the field of biomedical engineering. This comprehensive review covers the history of titanium in medicine, the properties of titanium and its alloys, the production technologies used to produce biomedical implants, and the most common uses for titanium and its alloys, ranging from orthopedic implants to dental prosthetics and cardiovascular devices. At the core of this success lies the combination of machinability, mechanical strength, biocompatibility, and corrosion resistance. This unique combination of useful traits has positioned titanium alloys as an indispensable material for biomedical engineering applications, enabling safer, more durable, and more efficient treatments for patients affected by various kinds of pathologies. This review takes an in-depth journey into the inherent properties that define titanium alloys and which of them are advantageous for biomedical use. It explores their production techniques and the fabrication methodologies that are utilized to machine them into their final shape. The biomedical applications of titanium alloys are then categorized and described in detail, focusing on which specific advantages titanium alloys are present when compared to other materials. This review not only captures the current state of the art, but also explores the future possibilities and limitations of titanium alloys applied in the biomedical field.

“…So konnten Hinrichs et al Eine 13-Jahres-Überlebensrate von 95,4 % bei glatter Oberfläche (R a 1,3 µm, R z ~10 µm) im Gegensatz zu einer 8-Jahres-Überlebensrate von 76,7 % bei rauer Oberfläche (R a 4,3 µm, R z ~25 µm) und sonst identischem Prothesendesign und identischer Implantationstechnik nachweisen [27]. Ähnlich gute Ergebnisse konnten in weiteren Studien für konische, zementierte Titanprothesen mit glatter Oberfläche (R a 0,2-0,4 µm) nachgewiesen werden [27,28]. Im Gegensatz hierzu berichtete Lichtinger et al In der Auswertung von grob gestrahlten Trios-Schäften über signifikant schlechtere Ergebnisse im Vergleich zu konventionellen femoralen Schäften mit einer Standzeit von 72% nach 3 Jahren [29].…”

ZusammenfassungDie Vorteile von Titanlegierungen gegenüber den herkömmlichen Stahl-, Kobalt-Chrom- und Chrom-Nickel-Legierungen als Material für Endoprothesen sind eine gute Dauerschwingfestigkeit, eine exzellente Biokompatibilität, ein niedrigeres Elastizitätsmodul und eine hohe Korrosionsbeständigkeit. Teilweise schlechte klinische Ergebnisse, vermutlich ausgelöst durch Spaltkorrosion, haben jedoch zu einer verminderten Benutzung geführt. Um einen sicheren Einsatz zu gewährleisten, sollte das Design optimiert werden (ausreichender proximaler Durchmesser, proximaler Kragen), um übermäßige Verformungen besonders im proximalen Anteil zu reduzieren, und auf eine raue Oberfläche (Ra > 2,5 µm) verzichtet werden. Eine Weiterführung der Forschung über Oberflächenbearbeitung, wie z. B. eine Silikat-/Silan-Beschichtung, könnte weitere Verbesserungen bewirken.
