Fracture of the ceramic head of a replacement arthroplasty of the hip has been encountered in 2 patients. After studying the literature the causation of such fractures has been assessed. Defects in manufacture of the prosthesis, damage during its handling and incorrect use may be responsible, with the tapered neck being the principal instrument of failure. The use of a new head with a used tapered neck is not recommended. Care must be taken in placing the head on the neck and a precise fit is required with no interposition of soft tissue.
在2例患者中出现了髋关节置换术中陶瓷股骨头骨折的情况。在研究文献后，对这类骨折的病因进行了评估。假体制造缺陷、操作过程中的损坏以及使用不当可能是原因所在，锥形颈部是主要的失效部位。不建议将新的股骨头与用过的锥形颈部一起使用。在将股骨头安装到颈部时必须小心，需要精确配合，不能有软组织夹在中间。
