Revision femoral stem SMR

cemented or non-cemented

The SMR revision stem for the hip is a modular system designed for hip resurfacing in cases of severe bone loss (type II, III and IV Società Italiana di Riprotesizzazione G.I.R. classification and type II and III Paprosky classification). With more than 20 years of clinical history, the femoral implant consists of three elements: a proximal component; a distal component; a locking screw. The SMR stem allows customized reconstructions thanks to the wide range of modular combinations of proximal and distal components. Materials Titanium alloy Ti 6Al 4V ELI, which guarantees excellent biocompatibility and mechanical resistance. The surface finish is obtained by abrasion with corundum granules that increase the contact surface and facilitate prosthesis-bone anchoring. Proximal Component The mirror polishing in the neck area has been designed to reduce the wear of the polyethylene in contact with the neck during flexion. The mirror finish also eliminates the risk fatigue cracking. Distal Component The distal component is conical with longitudinal fins. This prosthetic design guarantees axial stability and resistance to torsional forces at the same time. Three holes are positioned radially at 120° in the distal portion to allow the possible use of cortex screws in the rare cases where they are needed. SMR & SMR Resection The distal component of the SMR Revision Stem is also used in conjunction with the proximal component of the SMR Resection Modular Stem. The surgeon therefore has the option of using cemented or uncemented distal components for both SMR and SMR Resection prostheses, with different indications.
