Two parameters have been assessed: macroporosity and external shape (beads and parallelepipeds). In vitro, the ceramic beads were soaked in a Vancomycin-aqueous-solution, and the load of the antibiotic was then evaluated: it was 9.3% of the weight of the 40%-porosity beads and 4.6% of the weight of the 20%-porosity beads. The release has been evaluated by elution in phosphate-buffered-saline (PBS). With a 20% porosity, 12 beads (6.3 mm, 279 +/- 38 mg) demonstrated a short an massive release which ended within the 32 first hours. On the opposite, the release was sustained until the third week for the 40%-porosity beads (6.9 mm, 353 +/- 25 mg), while only one third of the load was released during the first 24 hours. A macroporosity of 40% of the ceramic could allow a deep incorporation of the antibiotic in the beads and thus decrease the rate of release. The in vivo study compared the bone concentrations of antibiotics obtained after implantations of either parallelepipedical or spherical devices in the distal femurs of 14 sheep. The bone concentrations of Gentamicin obtained with parallelepipeds until the end of the third week were from 5 to 10 times the minimum inhibitory concentration of this antibiotic for staphylococci. On the opposite, beads achieved only low concentrations of Vancomycin and nearly no detectable Gentamicin in the bone. We hypothesize a negative effect of the fibrous tissue which fills the gaps between the beads, and which could impair the diffusion of the antibiotics into the bone.</p>","PeriodicalId":10182,"journal":{"name":"Chirurgie; memoires de l'Academie de chirurgie","volume":"121 9-10","pages":"663-6"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20086821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is now well-established that the extent of bone loss around a total hip arthroplasty stem is related to stress shielding process. Due to a modulus mismatch between the bone and the implant material, the load transfer to the stem decreases the mechanical stimulus needed by the bone to maintain its structure. Because of its low modulus of elasticity and its good resistance to fatigue in aeronautical applications, the Fiber Carbon/Peek composite could potentially replace some of the metal alloys used in hip stem implant. After a literature survey on biomechanical performances of some fiber carbon composites, including AS4/Peek, experimental quasi-static and fatigue compression tests have been performed on AS4/Peek hip implants. The structural and mechanical characterization of the injection moulded composite material has been realized. The prosthesis compression and fatigue behaviour have been studied with a joint-stimulating apparatus immersed in a physiological solution temperature controlled. Instead of the low specimen homogeneity, no fatigue damage has been revealed either by X-ray observations of stiffness measurements, till ten millions of cycles. The quasi-static compressive fracture morphology has been analyzed by S.E.M. and have shown a good fiber matrix bonding. This mechanical results would suggest that AS4/Peek hip stem are worthy of further investigation as implantable prostheses.</p>","PeriodicalId":10182,"journal":{"name":"Chirurgie; memoires de l'Academie de chirurgie","volume":"121 9-10","pages":"658-62"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20086820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
