The iNSitu Hip System incorporates the latest technologies with core design principles to create a comprehensive total hip system designed for immediate and long-term success. 

The iNSitu Hip System is color coded. Liner groupings and head offsets are uniquely colored for quick reference during surgery.

 

Acetabular Cup

The titanium alloy acetabular cup is additively manufactured enabling a seamless integration of the engineered porous metal structure, porousTi™, and the solid substrate designed to ensure both solid initial fixation and long-term biologic fixation. An ideal three-holed screw pattern is accompanied with a large range of self-centering, self-tapping screws.

Acetabular Liner

The liners feature α-poly™, an Alpha-Tocopherol blended DCM polyethylene.  α-poly™ is a highly cross-linked, oxidation resistant, and ultra-low wearing material.  The liner is designed to provide optimal minimum poly thickness in critical loading zones and to allow for larger heads in smaller cup sizes. 

The liner "seats" in the acetabular cup prior to the final impact. Anti-rotational tabs and an interrupted annular (notched) locking ring are designed to provide stability and prevent wear.

 

Options Compatibility

  • Eleven sizes
  • Standard, face-changing and hooded liners available in all sizes

The iNSitu Hip System is color coded. Liner groupings and head offsets are uniquely colored for quick reference during surgery.

Along with the liner and head trials, the color coding is used for compatibility referencing on component packaging.

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 trunionosis. To promote superior proximal press fit, the stems feature a sintered asymmetric bead coating and are available in both standard and lateral offsets.

  • 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. A stem architecture designed to more accurately match anatomical variations and consistencies for optimal biomechanical reconstruction.

Femoral Head

Both BIOLOX® delta ceramic, known for their low wear and superior mechanical properties, and CoCr heads are available with several offsets to accommodate clinical needs.  Both head designs feature an ultra-smooth surface finish for optimal wear performance.

 

Options

  • Four sizes, multiple offsets
  • Size 40 heads available
  • BIOLOX® delta and CoCr
  • Skirted versions for high-offsets
