[Value of false profile of the pelvis in the monitoring of total hip prosthesis].
The authors used a retrospective series of cases of total hip replacement with a follow-up of between 6 and 12 years, including 10 undergoing reoperation for slipping of the prosthesis, to define the value of the false lateral view of the pelvis in the monitoring of such patients. This view provides earlier detection than AP views of wearing of polyethylene which manifests itself by penetration of the femoral head into the acetabular implant. This penetration, which can be measured radiologically, is better visualised in the false lateral view of the pelvis for simple reasons of radiological incidences. The false lateral view of the pelvis has another use in the monitoring of total hip replacements. It enables visualisation of the posterior part of the acetabulum which is generally the site of first appearance of the earliest signs of slipping in the form of a thin line.
