RI.HIP NAVIGATION

Overview

Take control. Get better.

With increasing patient expectations, it becomes more important than ever to deliver individualized component alignment.​

RI.HIP NAVIGATION empowers the surgeon with an assessment of individual patient pelvic tilt, a predicted view of the post-op AP X-ray in surgery and a digital measurement of leg length and offset changes.​

Take control with patient-specific cup placement

  • Compensate for pelvic tilt
  • Display in real time your cup orientation on the pre-op AP X-ray, simulating the post-op X-ray result
  • Provides confidence and controls outliers

Take control of leg length and offset

  • Allows a more accurate measurement of leg length and offset change compared to the conventional technique1-3
  • Pinless femoral reference
  • Only two registration steps required
  • Available as a standalone measurement or with cup positioning

Take control of your time with simplified registration1*

  • Take accurate control of pelvic tilt as well as leg length and offset while still being able to perform your total hip surgery in as little as just over 30 minutes for the most straightforward cases4

Get better more from your investment

Literature shows that improving patient satisfaction may lead to higher hospital reimbursement rates and increased patient loyalty.5-6

RI.HIP NAVIGATION is designed for the hospital or Ambulatory Surgery Center, with cost-efficiency and scalability as top requirements.

  • Image-free technology, no CT required
  • Small footprint platform
  • Scalable platform solutions with additional navigation or robotic-based TKA applications
  • Optional digital integration to EMR, PACS and PROMS

Get more reproducible results

  • Reduce outliers**
  • Improve acetabular positioning, as well as achieve more consistent leg length restoration compared to conventional techniques1-3

Get better performance with POLAR3♢7
Polarstem

  • POLARSTEM Cementless Stem
  • OXINIUM with XLPE
  • R3 Acetabular System​

**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.
