Periprosthetic bone densitometry of the hip: influence of prosthetic design and hydroxyapatite coating on regional bone remodelling.
OBJECTIVE To determine the influence of femoral hip prosthesis design and composition on regional periprosthetic bone remodelling as a function of time in asymptomatic patients. MATERIALS AND METHODS Bone mineral density (BMD) changes surrounding two differently designed porous-coated femoral prostheses (S-ROM, n=111; and Multilocki, n=62) were determined serially over a 24 month interval. Th...
متن کاملBONE DENSITOMETRY OF MENOPAUSAL WOMEN IN TEHRAN
Using a cluster sampling method, a group of menopausal women from three geographic areas in Tehran were asked to participate in the study. Demographic data was obtained using a questionnaire. Subjects were than referred to perform bone mass densitometry (BMD). The relationship between various variables (i.e. age of menarche, number of years of endogenous estrogen exposure, ... ) with minera...
متن کاملSynthesis and Characterization of Hydroxyapatite Layer on Cobalt Alloys through Dip Coating Method as a Prosthetic Bone Implant Candidate
This research aims to determine the effect of dip coating process parameter, which are the concentration of the suspension, withdrawal speed and sintering temperature on the crystallinity, surface morphology, shear strength and the thickness of hydroxyapatite (HA) coating on cobalt alloys substrate as a prosthetic bone implant material candidate. The coating is done at 3 different concentration...
متن کاملEvaluation of Influence of Zeolite/Collagen Nanocomposite (ZC) and Hydroxyapatite (HA) on Bone Healing: A Study on Rabbits
Bone healing is still a great challenge in orthopedic surgery and clinical practice. There is a dearth of research investigating the effect of Zeolite/Collagen (ZC) nanocomposite on bone regeneration. In the present study, a critical segmental defect of the rabbit femur was repaired using defects in femurs repaired by ZC nanocomposite, and the effects were examined histologically. In total, 45 ...
متن کاملCoating of titanium with hydroxyapatite leads to decreased bone formation
OBJECTIVES An experimental rabbit model was used to test the null hypothesis, that there is no difference in new bone formation around uncoated titanium discs compared with coated titanium discs when implanted into the muscles of rabbits. METHODS A total of three titanium discs with different surface and coating (1, porous coating; 2, porous coating + Bonemaster (Biomet); and 3, porous coatin...
