Bisphosphonate-coated external fixation pins appear similar to hydroxyapatite-coated pins in the tibial metaphysis and to uncoated pins in the shaft
BACKGROUND AND PURPOSE External fixation pins tend to loosen with time, especially from cancellous bone. A coating that releases a bisphosphonate has been shown to improve the fixation of dental implants in humans. We now tested a bisphosphonate coating on steel pins for external fixation. The primary hypothesis was that coated pins would be better fixed in the diaphysis. METHODS 20 patients ...
متن کاملSynthesis and Antimicrobial Activity of Silver-Doped Hydroxyapatite Nanoparticles
The synthesis of nanosized particles of Ag-doped hydroxyapatite with antibacterial properties is of great interest for the development of new biomedical applications. The aim of this study was the evaluation of Ca(10-x)Ag(x)(PO4)6(OH)2 nanoparticles (Ag:HAp-NPs) for their antibacterial and antifungal activity. Resistance to antimicrobial agents by pathogenic bacteria has emerged in the recent y...
متن کاملPreparation and Characterization of Hydroxyapatite Nanopowders Doped with Silver Ions
Silver doped hydroxyapatite was prepared by the precipitation method, using the precursor of hydroxyapatite, CaCl2-0.5M and (NH4) 2HPO4-0.3M; silver sulfate (Ag2SO4) is added to the precursors in order to bring the ions of silver (Ag at 10%) in the structure of hydroxyapatite. The morphology, structure and composition of prepared samples were characterized by X-ray diffraction, the complex ther...
متن کاملAntimicrobial Activity Evaluation on Silver Doped Hydroxyapatite/Polydimethylsiloxane Composite Layer
The goal of this study was the preparation, physicochemical characterization, and microbiological evaluation of novel hydroxyapatite doped with silver/polydimethylsiloxane (Ag:HAp-PDMS) composite layers. In the first stage, the deposition of polydimethylsiloxane (PDMS) polymer layer on commercially pure Si disks has been produced in atmospheric pressure corona discharges. Finally, the new silve...
متن کاملBone-hydroxyapatite interface in retrieved hydroxyapatite-coated titanium implants: a clinical and histologic report.
Two hydroxyapatite-coated implants were retrieved after 12 months of loading because of a fracture of the abutments. The specimens were treated to obtain thin ground sections, and a microprobe chemical analysis was done under a scanning electron microscope equipped with an energy-dispersive x-ray analysis and cathodoluminescence system. Under light microscopy, close contact between the bone and...
