iNSitu™ MicroBlade™ Hip System

Designed with bone preservation in mind, our shorter-length stem keeps the same proven proximal geometry as our iNSitu Dual-Taper Blade Stem, but with a 30 mm reduction in length. The result is a conservative option that supports minimally invasive techniques and helps retain more native bone, providing surgeons with added flexibility for a range of clinical situations. The head to stem taper junction has been specifically engineering to limit trunnionosis. To promote early stability and bone ingrowth, the stems feature a 0.25 circumferential press fit and a proximal plasma spray titanium coating. Both standard and lateral offsets are available.

Options

• Size 5 - size 22 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 consistencies, for optimal biomechanical reconstruction.

Femoral Head

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

Options

• BIOLOX® delta, Mg-PSZ, and CoCr

• Four sizes, multiple offsets

• Size 40 heads available

• Skirted versions for high offsets

Quick Reference Color Coding

The head trials are uniquely colored for quick reference during surgery.

The titanium-alloy acetabular cup is additively manufactured, enabling a seamless integration of our engineered porous metal structure, porosiTi™, with the solid substrate. The cup's unique design features ensure both solid initial fixation and long-term biologic fixation. An ideal three-holed screw pattern is accompanied by a large range of self-centering, self-tapping screws. The Multi Holed Cup offers additional screw fixation through a unique hole pattern that optimizes screw trajectory and bony purchase.

Options

14 cup sizes: Size 42 - Size 68
*size 42 and 44 cups are solid

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

• Eleven sizes

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

Options

The iNSitu™ Collared 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.
