Resumen (ES)
The supplementary fixation with screws non-cemented
acetabular hemispheric components is used to provide primary
stability to the implants. However, their use has been associated
to a bigger risk of neurological and vascular damage, characteristic
complications of the screws and osteolysis. The Xrays
of 30 non-cemented acetabular cups model Bihapro supplemented
with screws have been studied retrospectively with a 5
year-old minimum follow-up. It was also used an analysis program
and computer store of ¡mages. No neurological or vascular
damage took place. Any mobilization of the cup was not appreciated
and only in one case of an osteolytic area was observed
around a screw in a patient who unfderwent revision surgery. The
digitization of images is a technique that allows among other
advantages to graduate periprosthetic bone densities facilitating
an early diagnose of lytic areas and prosthetic micromovements
eliminating the observer's subjectivity.
