Trabecular Metal Collars in Endoprosthetic Replacements: Do They Osteointegrate?
Description
In this presentation, Ewen Fraser, a core trainee in Northern Ireland, discusses a study on trabecular metal collars used in endoprosthetic replacements and their osteointegration process. Conducted in Glasgow, the study addresses the growing incidence of primary bone malignancies in the UK and the need for effective limb salvage surgeries that ensure stability and allow weight-bearing functions. The research aims to determine whether radiological bone growth occurs with trabecular metal collars and how long osteointegration takes, utilizing a modified version of the Stanmore Radiographic Assessment System to analyze cases from 2010 to 2021.
The methodology involves assessing various aspects of radiolucency around the implant and measuring the effectiveness of osteointegration through x-ray evaluations. Preliminary findings suggest that approximately 65% of patients showed signs of osteointegration by the final x-ray, with results indicating that significant bone growth can occur as early as three months post-procedure. While the study highlights the effectiveness of trabecular metal collars, it also notes that the radiographic assessment method used may not be the most optimal for evaluating osteointegration outcomes.
