IB Lab HIPPOTM
HIP POsitioning Assistant
The measurement of hip angles is relevant in that doctors can take appropriate measures and therapies for early signs of hip disease. These include, for example, hip arthritis and hip dysplasia. HIPPO supports the objective and standardized measurement of the most important hip angles based on digital x-rays. These include, for example, the CCD and LCE angles as well as numerous other relevant angles.
IB Lab HIPPOTM
HIP POsitioning Assistant
For measurement of hip positioning and pelvic morphology.
10 radiological findings and measurements including:
LCE-angle, acetabular dysplasia, femoroacetabular impingement, CCD-angle, coxa vara, coxa valga, pelvic obliquity/leg length difference
NEW acetabular coverage measurements: Tönnis angle, sharp angle, extrusion index / femoroacetabular coverage
This product is CE-certified.
Not for clinical use in the USA.
Femoroacetabular impingement and hip dysplasia are the two main causes of hip degeneration, with the an end stage being total hip arthroplasty. Hip arthroplasty will grow from 1.8 million/year in 2015 to 2.8 million/year in 2050 in OECD countries , resulting in an increased workload for radiologists. Reading pelvic x-ray images requires in-depth knowledge of 3D pelvic morphology to correctly interpret the 2D projection. This is hard, subjective and error-prone. And on top of that, there will be a lot more of it in the coming years. Stress and reporting fatigue lead to differing levels of performance on x-ray interpretation, especially for non-experts, with certain measurements on hip radiographs shown to have high inter-rater variability . Unstructured reporting further leads to inconsistencies in the diagnosis process. Radiologists read an average of 10 hip radiographs per day, accounting for approximately 40 minutes of the daily workload .
IB Lab’s diagnostic support tool HIPPO uses deep learning technology for automated and precise measurement of hip angles such as Corpus-Collum-Diaphysis (CCD) angle (also known as Neck-Shaft angle) and the Lateral Center-Edge Angle (LCE). On bilateral standing AP hip radiographs, HIPPO supports the medical expert in the detection of the presence or absence of leg length difference. Readings are precise and reading and reporting time can be reduced from 3.5 minutes to 30 seconds per image when using HIPPO .
HIPPO highlights relevant clinical findings by applying the latest international medical standards to enable timely and accurate decision making. The findings are summarized in a visual output report, attached to the original x-ray image and saved automatically in the PACS system. The AI-results are fed as text into the predefined RIS-template for accelerated reporting. HIPPO eases disease progression monitoring by facilitating comparison of radiographic disease parameters over time. See how it works.
- Increases patient throughput by automating report workflows
- Enables instant, verifiable decision making in difficult cases
- Reduces effects of inter-rater variability when assessing pelvic morphology
- Facilitates monitoring of disease progression
Training & Validation
- Deep learning algorithms trained on over 4,000 individual pelvis and hip radiographs
- Data from five large longitudinal multi-center datasets in the US and Europe
- Reproducible to automatically recognizes and localize anatomically relevant landmarks on the hip and pelvis (teardrops)
- The AI follows the established radiological workflow: measurement of anatomical distances and angles, recognition of disease symptoms, standardized classification and reporting
- Consensus grading of each radiograph: Each detection step is done by an ensemble of three AI-models voting for the best result increasing precision
- Automatically detects implants at the hip
