Description

SMR System

The SMR hip revision stem is a modular system designed for prosthesis replacement in cases of serious bone loss (“Società italiana riprotesizzazione-GIR” grades II, III and IV and Paprosky grades II and III).With over 20 years of clinical history, the femoral implant consists of three elements: a proximal component, a distal component and locking screw.

The SMR stem allows customized reconstructions thanks to the wide range of modular combinations.

Proximal component

The modular proximal component solves the problem of restoring the physiological length of the limb and stabilizing the joint thanks to its four lengths 40, 50, 60 and 70mm and two CCD angles 125° and 135°.
The mirror polished neck area has been studied to decrease polyethylene wear during flexion. In addition, the mirror finish eliminates the risk of fatigue cracks.

Distal Component

The distal component is conical and has longitudinal fins, this prosthesis design guarantees axial stability and resistance to torsional forces at the same time;
The modular design has four lengths (100, 160, 200 and 240 mm) and ten diameters (14, 15, 16, 17, 18, 19, 20, 21, 22 and 24 mm);
The 200 e 240 mm distal components have a 3°anatomical pro-curvature to avoid point effects on the cortical;
The distal portion has three holes placed radially at 120° for cortical screws to be used in the rare cases they are needed.
