Iliac bone graft usually is not required with this technique, as the intramedullary rod is a load-sharing construct that allows compression at the fusion site and facilitates union. Rod removal usually is optional, and the long intramedullary beam effect of the rod can function as an internal splint if fibrous or hypoplastic union occurs. Early mobilization is possible, sometimes with only minimal splinting. The results with use of this technique over a ten year period of time in ten wrists (nine patients) with endstage radiocarpal joint instability are reported.</p>","PeriodicalId":79846,"journal":{"name":"Contemporary orthopaedics","volume":"24 4","pages":"393-400"},"PeriodicalIF":0.0,"publicationDate":"1992-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21021959","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}

A stemmed tibial component was used in 125 cases and an identical artificial knee without a stem was used in 307 cases. Follow-up was two to six years. Sinkage occurred in 0.8% of the cases with stemmed tibial components and in 3.5% of the nonstemmed tibial components, among which two (0.8%) required revision. The clinical results for both groups were similar. A small group of 34 patients who had a stemmed tibial component on one side and a nonstemmed component on the other also were examined.

Concerns have been expressed regarding cobalt-based alloys and the possibility of a future realization of a gross carcinogenic reaction from chrome-cobalt alloy implants. In this report, selected issues are reviewed and categorized for independent analysis to stimulate more comprehensive future research and theory formulation. Issues examined include those relating to metallic corrosion and potential local and systemic carcinogenic effects. The ionic valences of constituent materials, the electrochemical properties of the implant, and the proposed pathophysiological pathway of ions reportedly released from implants are traced. Tables listing 20 cases of primary neoplasia associated with total joint arthroplasty and seven cases reported in a 1975 study are discussed, compared, and contrasted. Finally, a selected bibliography is provided as a foundation for future study and research. In the author's opinion, the 50-year clinical experience and history of the use of cobalt-chromium as an implant material in orthopaedics, dentistry, and plastic surgery more than adequately establish its safety and effectiveness.</p>","PeriodicalId":79846,"journal":{"name":"Contemporary orthopaedics","volume":"24 3","pages":"265-78"},"PeriodicalIF":0.0,"publicationDate":"1992-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21043481","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}
