HipDysplasiaPro

Hip dysplasia leads to premature osteoarthritis of the hip and accounts for many of total hip replacements in patients. The early diagnosis is extremely important and is based mainly on the radiological findings. In a radiographs correctly performed measurements of Indexes like the Hip Value (HV), Acetabular Index (AI), or the Acetabular Index of the Weight-Bearing Zone (AIW) , the Center-Edge (CE), the Acetabular Depth-Width Ratio (ADR), the femoral head extrusion index or Reimer Index (RI), the Congruity Index (CI), the Sharp’s angle (SA), Tonnis grade of dislocation (TG), Congruence Index (CG) and the Acetabular Center Margin angle (ACM) are important for an the orthopaedic surgeon who wants objectively to asses and monitor optimally on standard radiographs the hips. These measurements usually performed in one X-ray by the traditional way which is time-consuming and cumbersome. The app approximate and combines true biomechanical conditions in hip as realistically as possible and can measure load and pressure on the affected hip. With measurements by the App and having numerical data it is possible to evaluate the efficacy or even predict it of the various procedures not on the basis of experience any more.

Simply by marking certain anatomical landmarks at each hip you measure in an instant, all these indexes ,and biomechanical status of the joint is calculated. The app also compares the results with normal age, gender and side specific reference databases retrieved from the international literature.

The Hip dysplasia PRO 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 eleven Indexes of hip dysplasia at once. By inserting the gender the age and marking certain anatomical landmarks -points at the same X-ray, at each hip, the App calculates the eleven above mentioned indexes (AI, AIWB, CE, RI, ADR ,CI, SA,TG, CG,HV,ACM) without to have to repeat each measurement separately. You measure all radiographic Indexes in one picture. Gender age and side-specific normal reference databases are used and in cases where values are out of normal ranges, the hips are categorized according the measured Index normal categorization.

- The App computes weight-bearing contact surface, the load (R) and stress (P) on the measured hip. Data from load and pressure distribution in the hip - like in a real biomechanicals tests- are being measured and depicted graphically as vectors over the X-ray in the screen over the joint. The distribution also of compressive stresses over the acetabulum, which is usually associated radiographic sclerosis over the acetabular margin, are printed in real time over the screen and thus can be easily and objectively evaluated.

-Besides that, the App provides for all Indexes and measured data an export module for diagrams of load (R) pressure (P), which each can be plotted as a curve allowing easy comparison with normal data and thus help decide the orthopaedic surgeon which procedure is objectively indicated.

-The data are printed over to screen so each case can easily assessed

-Save the planned images, the measured values and results compared by normal reference databases are exported as txt file, ready to print or to input as cells to numbers or excel ready for chart printing and further research or later review.
