“…Primary endoprosthetic replacement of a hip joint is therefore ranked sixth among the most common surgical procedures in Germany (Federal Statistics Office 2016). By international comparison and based on OECD figures, Germany is in second place amongst OECD countries and the USA, with its 287 primary hips replacements per 100 000 inhabitants [1].…”

Retrospective Comparative Study of the Influence on Quality of Primary Total Hip Arthroplasty by the EndoCert-Certification System in a Communal Hospital

et al. 2020

The EndoCert®-Initiative system sets specific requirements for the structural, process and result quality in certified Arthroplasty Centers in Germany. However, it remains unclear to what extent the certification process can increase the quality in total hip and knee arthroplasty. Aim of the comparative retrospective study is to analyse the change in quality of total hip arthroplasty in a communal hospital before and after the certification process. All primary total hip arthroplasties (n = 366) between 2013 and 2016 were included in the study retrospectively and grouped by treatment period. Treatment was performed in group 1 without clinical pathways, in group 2 pathway-controlled without a valid certificate and in group 3 pathway-controlled after final completion of the certification process. Outcome quality was analysed using quality indicators defined by the EndoCert-Initiative and further predefined indicators. Results show quality improvement under certified pathway-controlled treatment, e.g. time of surgery, cup and stem positioning, blood transfusion rate, periprosthetic fractures. However, improvements were not significantly in all cases and limitations must be recognized. Positive effects of the certification process legitimate capital investment and efforts. Further quality indicators may be implemented in the certification process to improve quality of treatment in arthroplasty.

“…Die Gründe hierfür liegen zum einen in der wachsenden Hinterfragung der Indikation zur endoprothetischen Versorgung von symptomatischen Gonarthrosepatienten. In den letzten Jahren hat in Deutschland die Anzahl der Knie-TEP-Erstimplantationen erstmals keine weitere Steigerung erfahren [1]. Man kann postulieren: Die Indikation zum Kniegelenkersatz wird aufgrund steigender Zahlen von Knie-TEP-Wechseloperationen [1] wegen Knie-TEP-Infektionen und -Lockerungen zurückhaltender gestellt.…”

Microstructure‐dependent crevice corrosion damage of implant materialsCoCr28Mo6,TiAl6V4andREX734 under severe inflammatory conditions

et al. 2022

View full text Add to dashboard Cite

Fretting corrosion is associated with increased risk of premature implant failure. In this complex in vivo corrosion system, the contribution of static crevice corrosion of the joined metal alloys is still unknown. The aim of this study was to develop a methodology for testing crevice corrosion behavior that simulates the physiological conditions of modular taper junctions and to identify critical factors on corrosion susceptibility. Samples of medical grade CoCr28Mo6 cast and wrought alloy, TiAl6V4 wrought alloy and REX 734 stainless steel were prepared metallographically and the microstructure was investigated using scanning electron microscopy (SEM). Crevice formers that mimic typical geometries of taper junctions were developed. Crevice corrosion immersion tests were performed in different physiological fluids (bovine serum or phosphate buffered saline with additives of 30 mM H 2 O 2 at pH = 1) for 4 weeks at 37 C. SEM with energy dispersive X-ray spectroscopy as well as focused ion beam were used to characterize the surface morphology, investigate present damages and identify the chemical composition of residues. Macroscopic inspection showed increased crevice corrosion susceptibility of TiAl6V4 and REX 734 under severe simulated inflammatory conditions. CoCr28Mo6 cast alloy exhibited degraded areas next to Cr-and Mo-rich precipitations that were located within the opposed crevices. The results indicate that aggressive electrolyte composition and crevice heights of 50-500 μm are critical influencing factors on crevice corrosion of biomedical alloys. Furthermore, manufacturing-related microstructure of common implant alloys determines the deterioration of corrosion resistance. The developed method should be used to enhance the corrosion resistance of common implant biomaterials by an adapted microstructure.
