Because of degenerative joint diseases and the reduced resistence in o
lder patients the correct diagnoses of joint-empyema is difficult. In
29 pat (> 60 y) the mean delay of diagnoses was 5.1 mounths. First loc
ation of the infection have been: urinary tract 12, pneumonia 6, skin
infection 10, and decubitus 3. Risk factors have been diabetes 4, poly
arthritis 3, gout 3 and tuberculosis 3. The species were: s. aureus 12
, s. albus 2, streptococcus 2, diphteroid 2, e. coli 2, pseudomonas 2,
proteus 4, enterobacter 3 and salmonella 1.8 patients demonstrated mi
xed infections. The high mortality (3 pat.) and the frequent general s
epsis (5 pat.) underline the importance of a missed joint-empyema in t
he elderly.
