What is it about?

Radiographic evaluation of the acetabular morphology is paramount importance for diagnosis, treatment, and follow-up management in dysplasia of the hip in children. One useful index for objective evaluation, how deep the acetabulum is, is the Acetabular Depth Ratio (ADR) or Acetabular Index of Depth. The app helps to measure the acetabular depth and acetabular width and calculates the Acetabular Depth Ratio (ADR). The behaviour of ADR as the child ages normally changes and increases as the acetabulum deepens with grow and reaches in adulthood its normal value usually over 48%. Monitoring the ADR index during treatment of hip dysplasia is crucial. The ADR offers an objective value in order to evaluate the acetabular remodelling.

App Store Description

Radiographic evaluation of the acetabular morphology is paramount importance for diagnosis, treatment, and follow-up management in dysplasia of the hip in children. One useful index for objective evaluation, how deep the acetabulum is, is the Acetabular Depth Ratio (ADR) or Acetabular Index of Depth. The app helps to measure the acetabular depth and acetabular width and calculates the Acetabular Depth Ratio (ADR). The behaviour of ADR as the child ages normally changes and increases as the acetabulum deepens with grow and reaches in adulthood its normal value usually over 48%. Monitoring the ADR index during treatment of hip dysplasia is crucial. The ADR offers an objective value in order to evaluate the acetabular remodelling.
The Acetabular Depth Ratio App is medical software aimed for orthopaedic surgeons, providing tools that allow doctors to:
-Securely import medical images directly from the camera or stored photos
-Offers a very convenient way to determine the most accurate possibly way the acetabular depth in percentage. By clicking three points and inserting the age, the gender and the side of the patient in the App, the measured value is compared with values from normal reference database. In case the measured value is beyond the normal range according to reference database, the hips are categorised as borderline, mild or severe dysplastic.
-Save the planned images, for later review or consultation.
The software is a class II medical device in the FDA. All information received from the software output must be clinically reviewed regarding its plausibility before patient treatment! Acetabular Depth Ratio App indicated for assisting healthcare professionals. Clinical judgment and experience are required to properly use the software. The software is not for primary image interpretation.

In a busy everyday practice measuring in X-rays in clinical settings it is time consuming and cumbersome. Accessory instruments like protractors, goniometers, well sharped pencils, rulers or even transparent papers must be available. The app offers a very convenient and accurate way to measure the value of Acetabular Depth Ratio by clicking three points. Also offers the ability all the data to be compared with medical reference database and help decide what could be considered normal or pathologic.
The app is not a simple goniometer, is an enhanced product which help to monitor objectively during the course of the treatment how much is deepening the acetabulum and evaluate the remodelling. This App is particular useful especially in clinical settings where you need a quick results without losing time in looking for reference data in textbooks. Please see tutorial videos at the developer’s web site
