↵4-150 The SI is a sum score, based on the presence of a knee/hip prosthesis (2 points), diagnosis of rheumatoid arthritis (1 point), comorbidity (1 point), age of 80 and over (1 point) (see table 3). For a 60 year old patient, the SI ranges from 0 to 4 because age does not pose an additional risk.
