Long-Term Radiographic Evaluation of Massive Proximal Femoral Replacements
Custom proximal femoral replacements have been designed and fabricated in the Department of Biomedical Engineering of the Institute of Orthopaedics since 1949. There have been many reports of their clinical results (Kemp 1987) as well as histological and mechanical studies of cemented intramedullary fixation (Scales et al., 1984; Wright et al, 1984). There are no reports, however, which document the radiographic changes which occur over time. This would provide an indicator of the likely durability of this method of fixation. In addition, a correlation could be attempted with clinical results. With the introduction of a new scheme for radiologic evaluation of prostheses after bone tumor resection and endoprosthetic replacement (ISOLS), we thought that such a radiographic study would provide useful data on application of the scheme.
