Background and study aims
About 1% of children are born with a loose, abnormally shaped hip joint, known as a dysplastic hip. Early detection in infancy allows for successful treatment with a harness or brace. If missed, there is a high risk of developing early osteoarthritis. Current clinical tests for hip dysplasia primarily detect severe cases, and traditional ultrasound screening has several limitations: it can be overly sensitive to minor shape changes, measurements on images are unreliable, and it is challenging for technicians to perform on squirming infants.
Early tests indicate that the 3D shape of the hip joint can be easily scanned using the same 3D ultrasound probe commonly used for fetal scans. These 3D images allow for optimal viewing angles without relying on the technician’s skill. 3D sequences are now included in some routine scans in Edmonton, and pseudo-3D models can also be created from video 'sweep' images recorded during conventional 2D ultrasound scans.
3D hip models are being developed based on existing ultrasound data. This study aims to further test and develop 3D hip ultrasound by determining the severity of hip dysplasia (if any) at each child's first visit, and by following each child's hip development and outcomes over several years. The researchers believe the 3D method will be easier to use at the bedside, measure hips more accurately, and provide valuable information about abnormal hip shapes. They are also testing artificial intelligence (AI) to automatically detect abnormal hips from 3D ultrasound or 2D "sweep" images. If successful, these methods could be applied to handheld portable ultrasound devices used by lightly trained personnel, such as primary care clinic nurses, potentially enabling widespread DDH screening.

Who can participate?
Infants aged from newborn to 12 weeks born in Alberta attending wellness checks (around 6-8 weeks) at participating sites

What does the study involve?
Each participant will undergo an initial 3D ultrasound scan to screen for hip dysplasia. Follow-up assessments will be conducted at regular intervals over a 5-year period to monitor hip development and clinical outcomes. All assessments involve non-invasive ultrasound imaging and clinical evaluations.

What are the possible benefits and risks of participating?
The potential benefits include more accurate and reliable detection of hip dysplasia, which can lead to early and effective treatment. There are minimal risks associated with the study as it involves non-invasive ultrasound imaging.

Where is the study run from?
University of Alberta (Canada)

When is the study starting and how long is it expected to run for?
July 2012 to December 2032

Who is funding the study?
1. Arthritis Society Canada (Canada)
2. TD Better Health Program (Canada)
3. Women and Children's Health Research Institute (WCHRI) (Canada)
4. Alberta Machine Intelligence Institute (AMII) (Canada)

Scientific titleAssessment of developmental dysplasia of the hip screening in infants by AI-enhanced 3D point-of-care ultrasound: correlation with clinical and imaging findings at initial infant screening and follow-up
Study objectivesThree-dimensional (3D) ultrasound, either obtained with 3D probe or by cine sweep with conventional 2D probe, enhanced with artificial intelligence (AI), could improve the accuracy and reliability of developmental dysplasia of the hip (DDH) screening in infants, compared to current single-image two-dimensional (2D) ultrasound methods, by providing more comprehensive imaging and enabling automated diagnosis even when performed by minimally trained personnel.
Ethics approval(s)

Approved 01/10/2012, University of Alberta Health Research Ethics Board (116 St & 85 Ave, Edmonton, T6G 2R3, Canada; +1 (0)780 492 3111; reoffice@ualberta.ca), ref: MS23_Pro00032107

Ethics approval additional informationThe University of Alberta Human Research Ethics Board granted a waiver of consent for this project, given that ultrasound is a harmless imaging modality, but the researchers still included a brief assent discussion with each family prior to performing scans.
Health condition(s) or problem(s) studiedDiagnostic screening for developmental dysplasia of the hip (DDH) in infants
InterventionParticipants undergo initial screening for developmental dysplasia of the hip (DDH) using AI-enhanced 3D ultrasound (by 3D probe and/or cine sweep) at well-baby checkups (6-10 weeks old). All data collection is non-invasive, with ultrasound imaging and clinical evaluations conducted during routine pediatric visits.
Intervention typeDevice
Pharmaceutical study type(s)Not Applicable
PhasePhase I/II
Drug / device / biological / vaccine name(s)Exo Iris (Exo Inc., Santa Clara, CA, USA)
Primary outcome measureDiagnostic accuracy of DDH screening (using the US/AI model) against gold-standard conventional clinical ultrasound diagnosis, as assessed by sensitivity, specificity, positive and negative predictive value and AUC at the time of baseline ultrasound
Secondary outcome measures1. Implementation success, assessed using the Consolidated Framework for Implementation Research (CFIR) 5-point framework, measured starting at initial rollout (2021), and every 3 years thereafter until the conclusion of recruitment (2024, 2027, 2030)
2. Feasibility of DDH screening (using the US/AI model) in neonates vs conventional physical assessments conducted by a physician at baseline, assessed by.System Usability Score (SUS), qualitative analysis of user and patient/family feedback from semi-structured interviews, and economic analysis. This is assessed every 3 years as above, based on data collected continuously and reviewed annually.
