To some extent, however, roentgen stereophotogrammetric analysis (RSA) may be used to compare implants137. This technique is able to accurately measure three- dimensional implant migration (up to 0.1mm for translations and 0.1 degree for rotations). RSA has been shown to have early predictive properties for implant failure, and may be used in the process of adequate phased introduction of new implants137.
Although there have been tremendous improvements over the years, challenges remain in e ective treatment of musculoskeletal tumors and in optimization of reconstructive techniques. Again, (inter-)national collaborative studies are needed, aiming for a golden era of cancer therapy, when, in the words of Gordon-Taylor, “gross mechanical destruction of disease and cruel mutilation of tissue shall be no more”138.
