The design of the extra medullary section improves the biomechanics of the stem. The low profile neck increases the range of motion of the stem within the cup before the neck impinges on the cup. Taper captures completely the femoral head reducing the potential for impingement of the cup. 150 μm hydroxyapatite coating on the grit-blasted surface of the FINER stem induces rapid osteointegration. The HA coated medial to lateral taper resists axial / torsional stresses and promotes osteointegration for optimum fixation. The design of the FINER stem, with its SS/Titanium alloy and its full hydroxyapatite coating ensures load transfer without abnormal peak forces3 and allows a very low incidence of thigh pain.
