Background:
Correct placement of the un-cemented cup is important in terms
of stability and longevity of the hip. The X-pander® measures both the geom-
etry of the acetabulum and the bone quality. The current report is part of a
multicenter trial.
Purpose / Aim of Study:
The aim of this registrations study is to examine
whether the use of X-pander in primary hip replacement improves cup fixation
and adaptation among trainee doctors.
Materials and Methods:
Immediately after the operation, the surgeon fills out
an evaluation form.
Findings / Results:
Among the 14 evaluation forms filled out, the use of X-
pander led to change in cup size in 3 cases (21%) and further reaming in 2 cases
(14%). The surgeons (n=2) felt more secure with cup placement (12 / 14) and
did not find any drawbacks with X-pander (11 / 14).
Conclusions:
The surgeons involved have in general expressed their satisfac-
tion with the functionality and clinical value of X-pander®. The device has the
potential improve cup-placement by trainee surgeons. A radiological evaluation
is planned.
