Developmental Dysplasia of the Hip (DDH) encompasses a spectrum of conditions where the hip joint is improperly formed, ranging from a mild acetabular shallowness to full dislocation. Early detection of DDH is crucial for effective management and prevention of long-term complications such as pain, limited mobility, or early-onset osteoarthritis.
Ultrasonography, rather than X-ray, is the preferred method for diagnosing DDH in infants, especially under the age of 6 months. Ultrasound provides a non-invasive and radiation-free way to visualize the soft tissues, cartilage, and bones in real time. The Graf method is the most widely used technique, where two critical angles—alpha (α) and beta (β)—are measured to assess the development of the acetabulum and classify the hip's condition.This application is designed to aid healthcare professionals—especially radiologists, orthopaedic surgeons—in evaluating DDH by calculating the alpha (α) and beta (β) angles quickl from saved ultrasound images of the patient hip.
Provide instant visual feedback by color-coding the angles:Alpha angle (α): red, Beta angle (β): yellow. Automatically also classify the hip joint based on the Graf method Type I,Type IIa/b,Type IIc,Type III, helping clinicians to have a quick glimpse and visualise the relationship between the angles ,real time.Healthcare professionals, particularly in busy departments, can save significant time by quickly loading ultrasound images and automating angle calculations, identify abnormal hips on the go . App can also be used as a training tool for medical students, residents, and junior clinicians, teaching them how to recognise key landmarks, make accurate measurements, and classify DDH using ultrasound images. By rapid visually displaying the measurements on the screen and generating easy-to-understand images, app helps clinicians explain the condition and its severity to parents.
App offers α and β angle measurement by dragging points on the ultrasound image to key anatomical landmarks, forming lines that define the acetabular roof and cartilaginous roof. The app automatically calculates the angles and classifies the hip condition based on these measurements in real-time.
Important feedback that help allow the user to adjust draggable points and see immediate changes in the angle values helping to fine-tune the position of the line
