Revisions of fractured, uncemented and extensively porous-coated femoral stems are challenging. In this article, we report three cases of revision surgeries for broken, cementless, and extensively porous-coated femoral stems with Solution™ stems (DePuy, Warsaw, Indiana). In all cases, minimally invasive endofemoral revision was successfully performed without femoral osteotomy or cortical fenestration. Removal of distal broken femoral stem was performed with hollow trephine technique under fluoroscopy. For revision arthroplasty of the femoral component, Solution™ stems of larger diameter were used. Endofemoral approach reduces duration of surgery and the amount of blood and bone loss. Minimally invasive technique for broken and uncemented femoral stem is recommended.
