Abstract
Background: The utilization of total joint arthroplasty is rapidly increasing, due to a growing elderly population and acceptance of implementation of total joint replacement in younger and older patients. As a result of these shifting boundaries, more complications of arthroplasty have been noticed. Not only the incidence of (a)septic steel and cup loosening and dislocations have risen, there is an epidemic of periprosthetic fractures. As the population in which total joint arthroplasty is performed ages, there are more periprosthetic fractures around total hip prosthesis. Such fractures are serious adverse events, often needing surgical treatment. Recent studies suggest that some of these periprosthetic fractures could be due to osteolysis around femoral cement restrictor used in cemented total hip prosthesis. Methods: We performed a retrospective multicenter study to measure the amount of osteolysis around four types of cement restrictors under a Link Lubinus SPII steel prosthesis using the ratio. The differences between the degree of osteolysis between the different cement restrictors were compared. Additionally we determined the incidence of periprosthetic fractures due to cement restrictor osteolysis. Results: The results of this study show that the Hardinge and the OptiPlug cause osteolysis in a five year period of follow-up. The OptiPlug causes the greatest number of osteolysis (T0-T2 13.25% (interquartile range 6.82-23.08)). In this study containing 953 patients divided on 3 cement restrictors, periprosthetic fractures were not directly related to osteolysis around femoral cement restrictors. Conclusion: The amount of osteolysis depends on the type of femoral cement restrictor, with the OptiPlug showing the greatest osteolysis. No clinical relevant periprosthetic fractures occurred in the follow-up period of five years. In the future, all implants should be registered and follow-up should be done more accurately.
