Adequate cohesive strength cannot be obtained when lipids are present on the surface to be joined by alkyl 2-cyanoacrylates. Oxidized regenerated cellulose gauze soaked in a highly concentrated fibrinogen solution was inserted into the partially hollowed fracture ends to arrest the flow of oozing blood from the medullary canal. Anhydrous ether was used to sponge off any residual lipid from the bone surfaces. The displaced fracture ends were aligned and narrow strips of bone were secured around the fracture line resulting in a barrel stave arrangement. Roentgenograms indicated successful reduction of transverse (midshaft) fractures in eight rat (femur) and seven rabbit (tibia) models. In some cases, casts were used as supplementary fixation. Using the ethyl and isobutyl 2-cyanoacrylates, reduced fractures were maintained in a stable position for up to five and six days, respectively. Further study of the 2-cyanoacrylates is recommended. By using a standardized surgical method for testing the usefulness of future adhesives in vivo, consistent interpretation of results will be facilitated.","PeriodicalId":75597,"journal":{"name":"Biomaterials, medical devices, and artificial organs","volume":"10 4","pages":"247-65"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3109/10731198209118784","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17921906","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}

Since this region is loaded in compression during gait, a simple fatigue fracture explanation is not sufficient to account for these cracks. It has been suggested that they are related to residual stress. It is known that residual stress can contribute a large part of the strain energy near a crack tip. Four failed T-28 femoral stems have been analyzed after surgical retrieval. All of them had multiple visible cracks on the medial side in the region 2-5 cm distal to the calcar collar. All had failed by transverse fractures connecting with a crack on the medial side. These stems have been examined for residual stress by x-ray diffraction methods; significant levels of residual stress were found to be present in the sections tested. Stresses in the transverse direction (medial to lateral) were found to be strongly tensile near the lateral edge and changed to compressive near the medial edge. The area in the center of the sections was found to have nearly zero residual stress.","PeriodicalId":75597,"journal":{"name":"Biomaterials, medical devices, and artificial organs","volume":"11 1","pages":"13-20"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3109/10731198309118790","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17672023","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}
