The reconstruction assembly consists of: (i) a cross-shaped metal base (4) fixed in the cotyloid cavity; (ii) a metal cup (2) held in place by cement; and (iii) a polyethylene liner (3) fitted inside the cup, capable of multi-directional rotation. The reconstruction assembly, designed to receive a hip joint prosthesis, consists of: (i) a cross-shaped metal base (4) fixed in the cotyloid cavity; (ii) a metal cup (2) held in place by cement; and (iii) a polyethylene liner (3) fitted inside the cup and capable of multi-directional rotation. The cup has a beveled led inner edge (2f) to reduce any cam effect, and its outer surface is made up of two sections of a sphere with different radii, tangential at the pole, and a cement pressure collar (2b) with a series of semi-circular recesses to release surplus cement.
