1. By pressing the cross over the middle of patella - the order of the side you choose is irrelevant - flexion and abduction angles (ABD1,FL1) are printed over the screen in relation to the imaginary sagittal and coronal plane for the side accordingly.

2. The degree of flexion and abduction of the thighs placed by the harness or the splint could be measured by using simple plastic orthopaedic goniometer but you have to measure two angle for each hip namely to measure four times and record manually the degree of four angles in each patient’s visit.

3. Next you mark - by the same manner the other side, aiming at the middle of the patella and pressing over the cross, flexion and abduction angle of the corresponding hip (ABD2, FL2) are calculated and printed on the screen.

4. The combined degree of abduction of both extremities in relation to the saggital plane is especially valuable during treatment because you can detect any asymmetry in abduction or flexion due to harness straps loosing and respectively corrected.

5. -By marking certain anatomical landmarks though a ’cross’ in front of your screen, determine the most accurate possibly way, in live images directly from the camera, in front of your screen in space, flexion and abduction of hips concurrently and objectively.

6. To achieve a favourable outcome in treatment of Developmental Dysplasia of the Hip (DDH) the surgeon must measure the degree of abduction or flexion objectively in each patients visit.

7. By recording each patient visit you can keep track of the changes in degrees either in flexion either in abduction and taken into account,you can adjust objectively the flexion and the adduction of a splint and harness.

8. According to surgeons’ experience the degree of abduction or flexion of the splint or flexion harness should be modulated.

9. Three anatomical landmarks points have to be marked in certain order namely one in a middle of the gluteal fold (P1), second in pubic symphysis (P2), and over the navel (P3) - an imaginary sagittal plane over patient’s body in the middle plane.

10. The Papadimitriou Harness AR App is a software develop for augmented reality helping the surgeon to evaluate and monitor the children under therapy with splint or harness.

11. By aiming the cross at the anterior superior iliac spines (ASK) left (S1) or right - (independent from order of selection) and pressing over the cross over the image - the (S1) point is marked.
