The DePuy Synthes PROTRUSIO Cage offers a useful treatment option for the revision acetabulum. The PROTRUSIO Cage may be considered as a method of enhancing cemented acetabular reconstruction when traditional biologic fixation with a hemispherical porous-coated acetabular component is not indicated or possible.
The PROTRUSIO Cage aids the surgeon in restoring the hip’s centre of rotation while gaining secure fixation to host or allograft bone through iliac and ischial fixation. By addressing medial wall deficiencies, antiprotrusio cages have proven to work well in the revision setting.1,2
