Abstract
An orthopaedic prosthetic hip assembly and method for use during performance of a hip replacement procedure. The assembly includes a femoral stem component having a tapered trunnion and a femoral head component having a tapered bore. Upon insertion of the tapered trunnion into the tapered bore, a taper lock is formed and a seal provides a fluid-tight closure.

A method of assembling an orthopaedic prosthetic hip assembly, the method comprising:
- positioning a compressible seal in an annular slot of a femoral head component, the femoral head component being configured to engage a surgically-prepared acetabulum or a prosthetic acetabular cup,
- positioning a tapered trunnion of a femoral stem component in a distal opening of the femoral head component, and
- engaging a flange of the femoral stem component with the compressible seal.

- positioning a tapered trunnion of a femoral stem component in a distal opening of the femoral head component, and
- securing the compressible seal between the femoral stem component and the femoral head component to prevent fluid from advancing proximally along the tapered trunnion.
