Extract
Surgical treatment choices for recurrent dislocation of the hip include
isolated soft-tissue
tightening1 or
revision of prosthetic components with use of an array of options, including
standard components implanted in satisfactory
position1,2,
constrained acetabular
devices1,3,
elevated-rim polyethylene
components3,4,
and the use of larger prosthetic femoral
heads3,5.
The last treatment option is facilitated by the recent availability of larger
prosthetic heads and cups that use highly cross-linked
polyethylene6,7.
We report the case of a patient who had recurrent dislocation after a total
hip replacement, in which the orientation of the acetabular component was
suboptimal and had been unsuccessfully treated initially with a large femoral
head. The patient was informed that data concerning her case would be
submitted for publication.
