Fig. 1From: Total hip arthroplasty with femoral osteotomy and modular prosthesis for proximal femoral deformityModular S-ROM prosthesis. The prosthesis consists of a porous-coated sleeve proximally for press-fit fixation and a fluted and slotted stem distally for producing an intramedullary nail fixation effect. The intramedullary filling of the prosthesis distally and proximally can simultaneously achieve stable fixation of the distal and proximal femurBack to article page
