RI.HIP NAVIGATION is a Smith+Nephew proprietary technology that is part of Real Intelligence, an ecosystem that creates a seamless connection through the continuum of care by combining robotics, software and data to improve outcomes.

To realize this vision Smith+Nephew has made significant investments in technology including: Bluebelt, Atracsys and Brainlab.

RI.HIP NAVIGATION relies on over 10 years of hip navigation by Brainlab to now deliver individualized component alignment. Next to the digital measurement of leg length and offset changes, it empowers the surgeon with an assessment of individual patient pelvic tilt and a predicted view of the post-op AP X-ray in surgery thanks to its seamless integration withTraumaCad.

*The references provided relate to previous versions of hip navigation which RI.HIP NAVIGATION is built on.
**Outliers are defined as cups outside the most commonly used safe zone, the Lewinnek Safe Zone. The Lewinnek Safe Zone describes an area of 40°±10° for cup inclination and 15°±10° for cup anteversion for which (Lewinnek et al. 1978) a reduced probability of postoperative dislocation was found. Hence the area is further addressed as a zone for safe cup placement in respect to dislocation. Despite concerns of its validity the Lewinnek Safe Zone is still the most commonly used safe zone for cup placement addressed in the literature.
