AcetabularAnteversionApp vs ICODE Hip US Calculator

Acetabular version refers to the anteroposterior orientation of the acetabular opening relative to the true horizontal axis of the pelvis. The normal human acetabulum is anteverted in order to allow impingement free range of motion including flexion, adduction, and internal rotation. Abnormal acetabular version has been correlated with pathologic hip conditions including femoroacetabular impingement (FAI) and developmental hip dysplasia.The association between acetabular version and hip pain has been well established in recent years as a source of contributing to early hip osteoarthrosis and labral tears. Recognition and appropriate treatment of abnormal acetabular version is crucial to preventing irreversible damage to the hip Acetabular version is conventionally evaluated on CT scans but excessive radiation doses associated with routine use of computed tomography (CT). An objective radiographic tool which provides measurements comparable in accuracy to CT measurements has been developed by Dr. Hefti (Nomogram).Tedious and time-consuming calculation has to be done in simple X-rays in order to calculate the acetabular anteversion. The primary goal of this App is to help determine radiographic values of acetabular anteversion in a practice in a blink of an eye and avoiding CT scans. The 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. -By marking certain points in a simple standard AP pelvic radiograph, geometric parameters are being calculated. The App computes the acetabular anteversion based on a pelvic AP radiograph. The angle of anteversion is calculated through the formula according to Heftis nomogram. The acetabular orientation (anteversion/retroversion) is determine by the app by the measurement of the angles between the center of the femoral head and the anterior (φ) and posterior (φ’) acetabular rim. Once you choose correctly the anterior and posterior acetabular rims the app calculates the acetabular anteversion based on nomogram. -The data are printed over to screen so each case can easily assessed -Save the planned images, for later review or consultation. Disclaimer. Regarding its plausibility app offers no diagnosis or treatment. App provide an early indication that further evaluation may be warranted by Speciality Doctor. Explicitly is announced that the apps are not for diagnosis. Clinical judgment and experience are required to properly use the software. App alone do not replace an M.D. or specialist. All information received from the App output must be reviewed before any attempted treatment. The software is not for primary image interpretation. Any influence to the operators in making decisions remains user own responsibility and experience. App does not dispense medical advice. Patient should seek a doctor’s advice in addition using the app and /or before making any medical decisions for themself. Never substitute or replace doctors advice or change treatment modalities based on any measured outcome. App indicated for assisting healthcare professionals for scientific and research reason. Clinical judgment and experience are required to properly use the app and further research and validation is pending in coming future.

The application is intended for use only by healthcare professionals. The main goal of the application is to be an easy-to-use and useful tool for calculating a babys hip type. The healthcare professional will provide some basic information about the baby after examination like the baby birth date, date of examination and both infant hip angless (in degrees). Based on an algorithm the application will display a result abount the infant's hip type. Also instructions are displayed based on the result. Healthcare professionals who use it, do so at their own risk and should exercise their own clinical judgment as to the information they provide to the patients. We have tried to create content to conform to the standards of professional practice that prevailed at the time of development. However, standards and practices in medicine change as new data become available and the individual medical professional should consult a variety of sources. Medical information changes rapidly.
