Acetabular Cup Revision
The use of acetabular cup revision arthroplasty is on the rise as demands for total hip arthroplasty, improved life expectancies, and the need for individual activity increase. For an acetabular cup revision to be successful, the cup should gain stable fixation within the remaining supportive bone of the acetabulum. Since the patient's remaining supportive acetabular bone stock plays an importa...
متن کاملA technique for removing an intrapelvic acetabular cup.
We describe a simple, retroperitoneal approach for the removal of acetabular components that have migrated into the pelvis. The dense fibrous tissue layer which surrounds the implant protects the iliac vessels during removal of the cup by this method.
متن کاملThe assessment of Charnley acetabular cup malposition.
Technical errors are the commonest cause of dislocation of hip prostheses (Hamblen 1984). An excessively anteverted or retroverted acetabular component is often responsible. The deleterious effects of such malposition have been documented by Ackland, Bourne and Uhthoff (1986), Fackler and Poss (1980) and Lewinnek et ab (1978). These workers were abbe to measure anteversion or retroversion by ut...
متن کاملMeasurement of the acetabular cup anteversion on simulated radiographs.
Widmer (J Arthroplasty 2004;19:387) reported a protractor for measuring the anteversion of acetabular cups on radiographs but with limited precision. We intended to improve its precision by trigonometric mathematics. We measured the anteversion of the acetabular cups on 336 simulated radiographs using aforementioned 2 methods. The anteversion measured by Widmer's protractor ranged from 7 degree...
متن کاملSevere osteolysis after third-body wear due to hydroxyapatite particles from acetabular cup coating.
One concern about the fixation of HA-coated implants is the possible disintegration of the surface, with the migration of HA granules into the joint space, producing third-body wear. We report a study of six revisions of HA-coated polyethylene RM cups at 9 to 14 years after successful primary arthroplasty. In all six hips, we found HA granules embedded in the articulating surface of the polyeth...
