Research proposal abstract
Radial head arthroplasty (RHA) is increasingly used as a treatment for both traumatic and post-traumatic radial head fractures. Radial head prosthesis can be placed using either cemented or cementless fixation. (2,3,4) To date, controversy persist regarding the superior implant type and fixation method as most studies evaluate only a single type of stem fixation (7). To the best of our knowledge, studies reporting on different types of stem fixation within the same cohort are scarce and prone to bias, which limits the identification of superior designs and fixation techniques (12).
Therefore, the primary aim of this study is to assess the difference in implant survival between uncemented and cemented implants.
Patient and treatment characteristics will be compared and multivariable cox proportional hazards regression models will be used to assess a possible association between fixation method and implant survival.
Efforts will be made to combine the data from the LROI with data from other national registries, such as those of Australia, Norway, Sweden and New-Zealand.
