Abstract
BACKGROUND:Recent studies indicate that osteolysis surrounding prosthesis is the main reason causing artificial joint loosening.The reason and development process of osteolysis surrounding prosthesis are not fully understood.OBJECTIVE:To observe the pathological changes of limiting membrane surrounding sterile loosened prosthesis of artificial hip ioint and compare that with cicatricial tissue surrounding internal fixation.DESIGN,TIME AND SETTING:Histological observation was done at The Second Hospital of Soochow University between September 2000 and December 2005.PARTICIPANTS:Limiting membrane surrounding prosthesis of eight artificial hip joints overhauled for loosening were removed during operation for pathological examination.METHODS:Specimens were fixed with 10%formaldehyde solution and embedded with paraffin,and were cut into sections,the sections were stained by hematoxylin-eosin(HE)staining and immunohistochemistry staining.The specimens were done bacterial culture.MAIN OUTCOME MEASURES:Histopathological changes.RESULTS:Wear particles,cellular proliferation and osteolytic factors were found in the limiting membrane surrounding loosening prosthesis.The bacterial culture results of the specimens were negative.CONCLUSION:Wear particles generated in the using process of prosthesis can activate osteolytic factors produced by inflammatory cells and is an important reason leading to sterile loosening of prosthesis.关键词
