A 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 کاملA Powered Technique for Inserting Acetabular Cups
This work focused to investigate the use of a powered automatic technique to insert acetabular cup implants. The use of a percussion hammer tool as a surgical instrument to insert acetabular cup implants was investigated in current work. Pull-out, lever-out and torque tests were carried out on cup implants inserted into test block specimens of polyurethane (PU) using specifically designed exper...
متن کاملAcetabular 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 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 کاملSurvival of uncemented acetabular monoblock cups
BACKGROUND AND PURPOSE Monoblock acetabular cups represent a subtype of uncemented cups with the polyethylene liner molded into a metal shell, thus eliminating-or at least minimizing-potential backside wear. We hypothesized that the use of monoblock cups could reduce the incidence of osteolysis and aseptic loosening, and thus improve survival compared to modular designs. PATIENTS AND METHODS ...
