Critical radiological analysis after Austin Moore hemiarthroplasty.

摘要: The aim of this study is to investigate the causes prosthesis loosening in patients treated with Austin Moore hemiarthroplasty (AMA). clinical and radiological outcomes were documented a quantitative manner after 7 years follow-up 144 patients. At time final follow-up, 52 had died 48 lost leaving total 44 for analysis. Immediate post-operative X-rays studied initial alignment prosthesis, fit degree osteoporosis. on latest evidence loosening. All assessed clinically hip score hospital special surgery. It was found that pain significantly related subsidence pivoting (P = 0.014 0.035, respectively). Significant increase noted if stem not fitting well within shaft femur 0.006). When patient younger than 73 old at operation, there more 0.001). concluded fill AMA should be greater 70% avoid early Relatively acute fracture neck by methods other cementless AMA.
