iNSitu™ Blade Femoral Stem

The unique, titanium alloy, stem design features a quadruple taper geometry designed to restore joint biomechanics, stability, and load transmission.  The head to stem taper junction has been specifically engineered to limit trunnionosis. To promote superior proximal press fit, the stems feature a sintered asymmetric bead coating and are available in both standard and lateral offsets.

Options

  • Size 1 - size 14 available

  • Standard and lateralized offsets for each size

Progressive Lateralization

A lateralized version of each stem is available, providing a progressively greater horizontal offset with each size, while still maintaining leg length, vertical offset and neck angle. The stem architecture is designed for a more accurate match with anatomical variations and inconsistencies, for optimal biomechanical reconstruction.
