Abstract
Abstract An apparatus for facilitating the filling up of a shaft bored into human femoral bone during hip replacement surgery with gelatinous methyl methacrylate bonding cement for receipt of an artificial hip prosthesis so as to maximally prevent loosening of the prosthesis after hardening of the cement consisting of a hollow cylindrically shaped applicator tube, a top end of a hollow first portion thereof which is characterized by the presence of threading threreabouts and a bottom end of which first portion has affixed to it, a top end of a hollow second portion about a centrally located through hole in a base of the first portion with there being affixed to a bottom end of the second portion a circular shaped flexible tip component.
