THR BHR CEMENTED UNCEMENTED PRIMARY REVISION TUMORAL RESURFACING HEMI-ARTHROPLASTY LARGE HEAD

Cemented

•Approximately 10min

Cementless

•One year for good ingrowth

•Up to two years for 100% of

ingrowth bone (30% of the total

porous surface)

90% polymethylmethacrylate (PMMA) 10% Barium Sulfate

Particles from loose cement cause abrasive wear in the acetabular joint

Vacuum mixing decreases voids in the bone cement which decreases stress concentrations within the hardened cement
