Arthrography for the assessment of pain after total hip replacement. A comparison of arthrographic findings in patients with and without pain
WR Murray and JJ Rodrigo
Arthrography in twenty-five painful hips of twenty-one patients after total
hip replacement and in fifty-three asymptomatic hips of forty-two patients
after this procedure showed that arthrographic evidence of loosening was
not always associated with pain. More than one-fifth of the asymptomatic
hips had arthrographic evidence of loosening. Furthermore, the loosening
shown by arthrogram could be confirmed in only seven of twelve hips that
were subsequently explored. In addition, there was no apparent relationship
between arthrographic loosening and the presence of a Trendelenburg sign.
This study casts doubt on the value of an arthrogram in the diagnosis of
the cause of pain after total hip replacement.
