In Total hip Arthroplasty the orientation, namely anteversion and inclination of the new acetabular component -cup- influences wear, range of movement (ROM), and the likelihood of dislocation after total hip replacement (THR). Evaluating objectively of the cup anteversion, and inclination in hip arthroplasty replacement surgery is of paramount importance. Radiographs are the most important diagnostic means in the follow-up for evaluation of a total hip arthroplasty. Measuring anteversion and inclination in everyday clinical setting is a cumbersome work for a medical doctor. Computation requires a calculator, which requires an additional effort during practice and slows down workflow.
The App is medical software aimed for orthopaedic surgeons, providing a tool that allow doctors to:
-Securely import medical images directly from the camera or stored photos.
-By marking certain anatomical landmark and points in a simple standard AP pelvic radiograph, values for cup inclination and anteversion are being calculated. The app is based on Widmer’s method which is the proven that is the most accurate compared to others.
-The data are printed over to screen so each case can easily assessed
-Save the planned images, for later review or consultation.
The app offers an easy way to quantify cup anteversion and inclination a quick and comfortable manner without the use of a goniometer or a ruler or to calculate elaborated formulas.
All information received from the software output must be clinically reviewed regarding its plausibility before patient treatment! The App is 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 THA practice, the examiner to draw lines in X-rays, it is time consuming and cumbersome. Accessory instruments like calculators, protractors, hinged goniometers, well sharped pencils, rulers or even transparent papers must be available. This App is particular useful in clinical settings where you need a quick results without losing time. Please see tutorial videos at the developer’s web site www.orthopractis.com
