In athletes, osteoarthritis of the symphysis pubis is an uncommon cond
ition that should be promptly differentiated from pubic pain due to mi
crotrauma. The symphysis pubis is infected via the bloodstream, usuall
y by a staphylococcus. Pubic pain with fever and severe disability sug
gests the diagnosis. Increased uptake of bone-seeking radionuclides is
an early finding. Microbiological and histological studies of specime
ns obtained under radiological guidance confirm the diagnosis. Two new
cases of pubic osteoarthritis in young athletes are reported. In one
case the causative organism was a Peptostreptococcus, a gram-positive
commensal organism normally found on the skin and mucous membranes.
