Comparison of cement pressurisation in flanged and unflanged acetabular cups
BACKGROUND This biomechanical study examined difference in cement pressures generated by flanged and unflanged acetabular cups in hip arthroplasty. METHOD Using a model acetabulum, cement was inserted and pressurised followed by cup insertion and pressurisation. Pressures were recorded using transducers in the acetabulum. We compared Charnley Ogee (flanged), Exeter contemporary (flanged) and ...
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 کاملAn improved acetabular cementing technique in total hip arthroplasty. Aspiration of the iliac wing.
We have evaluated the effect of vacuum aspiration of the iliac wing on the osseointegration of cement into the acetabulum. We entered a total of 40 patients undergoing primary total hip arthroplasty into two consecutive study groups. Group 1 underwent acetabular cement pressurisation for 60 seconds before insertion of the acetabular component. Group 2 had the same pressurisation with simultaneo...
متن کاملComparison of flanged and unflanged acetabular cup design
BACKGROUND AND PURPOSE Adequate depth of cement penetration and cement mantle thickness is important for the durability of cemented cups. A flanged cup, as opposed to unflanged, has been suggested to give a more uniform cement mantle and superior cement pressurization, thus improving the depth of cement penetration. This hypothesis was tested experimentally. MATERIALS AND METHODS The same cup...
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 ...
