One hundred cases of hip prosthesis failure were classified on the basis of the different types of tissue reaction occurring around alloplastic material. The results revealed infectious phlogosis in 32% of the cases, phlogosis due to wear in 42%, phlogosis due to allergy in 1% and mixed phlogosis in 25%. The distribution of the type and degree of intensity of the phlogosis, in relation to the duration of the implant, is also highlighted. This new grading technique yields reproducible results.
根据异体材料周围出现的不同类型组织反应，对100例髋关节假体失败病例进行了分类。结果显示，32%的病例为感染性炎症，42%为磨损性炎症，1%为过敏性炎症，25%为混合性炎症。还强调了炎症类型和强度程度与植入时间的关系。这种新的分级技术产生了可重复的结果。
