“…El arenado cambia la composición de la superficie [1][2][3] , aunque la presencia de las partículas residuales no parece tener un efecto en la osteointegración [4] . Datos obtenidos in vivo han puesto de manifiesto que las superficies rugosas producen una fijación mecánica u osteointegración mejor que la correspondiente a superficies lisas [5][6][7] . Este tratamiento tampoco compromete el buen comportamiento a corrosión in vitro de las aleaciones de titanio [3 y 8] .…”

“…Experimentally, Goldberg et al (1995) favored a grit-blasted titanium alloy surface of R a = 4 µm approximately rather than a polished or fiber-mesh surface of the same material. Titanium implants with a rough surface have the ability to promote extensive bone-implant contact, as demonstrated histologically in both experimental (Albrektsson and Johansson 2001) and human retrieval studies .…”

Background The long-term results of uncemented total hip arthroplasties vary widely due to differences in design, metal alloy, coating, surface structure, and porosity.Patients and methods We retrospectively studied 75 cementless Zweymüller SL stems in combination with Endler titanium-backed threaded cups (Z-E) in 70 patients. 35 patients were women, and the mean age at surgery was 52 (24-68) years. 16 patients died and 1 emigrated, 7 patients (of which 1 later died) subsequently underwent revision, and the remaining 47 patients with 50 original arthroplasties were followed up after a median of 16 (15-18) years.Results Revision of 8 hips resulted in an 18-year Kaplan-Meier estimated overall survival rate of 88% (CI: 79-96). 6 of 7 cup revisions were due to liner wear and osteolysis, and 1 was due to aseptic loosening. 2 of 3 stem revisions were due to femoral loosening and 1 was due to fracture of the neck of the stem. The clinical results were good, with a mean Harris hip score of 89 (54-100). Half of 70 hips in 65 patients had ectopic bone formation. All unrevised implants were radiographically stable, with a mean liner wear of 0.07 mm/year. Interpretation These long-term results demonstrate that the combination of a Zweymüller SL stem and an Endler titanium-backed screw cup is a good hip arthroplasty in young and active patients. A prefixed polyethylene liner is a drawback, necessitating exchange of the whole cup in cases with polyethylene wear.

“…A high frequency study using the Olympus UH3 SAM (Olympus Co., Tokyo, Japan) at Case Western Reserve University (CWRU) was performed using a 400 MHz burst-mode lens on histologically prepared samples of porous Ti plugs with and without hydroxyapatite coatings that had been inserted in rabbits at CWRU [146][147][148]. The SAM study showed that there were significant differences in formation and remodeling from woven to haversian bone as a function of both time of implantation and the presence or absence of hydroxyapatite coating in the pores [149].…”

This paper presents a review plus new data that describes the role hierarchical nanostructural properties play in developing an understanding of the effect of scale on the material properties (chemical, elastic and electrical) of calcified tissues as well as the interfaces that form between such tissues and biomaterials. Both nanostructural and microstructural properties will be considered starting with the size and shape of the apatitic mineralites in both young and mature bovine bone. Microstructural properties for human dentin and cortical and trabecular bone will be considered. These separate sets of data will be combined mathematically to advance the effects of scale on the modeling of these tissues and the tissue/biomaterial interfaces as hierarchical material/structural composites. Interfacial structure and properties to be considered in greatest detail will be that of the dentin/adhesive (d/a) interface, which presents a clear example of examining all three material properties, (chemical, elastic and electrical). In this case, finite element modeling (FEA) was based on the actual measured values of the structure and elastic properties of the materials comprising the d/a interface; this combination provides insight into factors and mechanisms that contribute to premature failure of dental composite fillings. At present, there are more elastic property data obtained by microstructural measurements, especially high frequency ultrasonic wave propagation (UWP) and scanning acoustic microscopy (SAM) techniques. However, atomic force microscopy (AFM) and nanoindentation (NI) of cortical and trabecular bone and the dentin-enamel junction (DEJ) among others have become available allowing correlation of the nanostructural level measurements with those made on the microstructural level.
