An App that merges computer assisted orthopaedic surgery (CAOS) features with Apple's advanced Augmented Reality modules, helps orthopaedic surgeon to navigate ..

 The App is medical App software aimed for orthopaedic surgeons, providing a tool that allows the surgeon to expedite the stage of femur neck resection during hip replacement surgery effortlessly by adjusting intra operatively the femoral neck resection level according to preoperative measurements thus allowing accurate cutting of femur neck. The app works by offering:
-A red hazy plane appear perpendicular to yellow cylinder depicting the femoral neck the point of intersection between the planes, by pressing the + or - Button you can adjust intra operative in augmented reality the exact resection level of the femoral neck you plan and see simultaneously where resection level should be - depicted by the moving red plane in real time - The red plane intersect the distance from centrum of femur head to trochanter minor, the osteotomy length value is printed in real time continuously in screen and adjusted according to preoperative desired femur neck resection distance in mm.
- Three perpendicular planes around the saw blade appear with different hazy transparent colours (sagittal-blue, coronal-red, transverse-green) in augmented reality (AR ) over the tip of the bone saw blades extending to the end over the blade left-right span dimension.
-Over the screen in real time three angles corresponding to the direction of saw blade are depicted. Manipulating the Oscillating Bone Saw Cutting Machine Orthopedic Power Tool in real time the surgeon, values of all above mentioned angles change respectively, obtaining positional information and direction with accuracy in real time in augmented reality by observing the screen of the i-phone. Angle values in real time are printed in different colours in screen, whenever the values fall outside the normal ranges.
-The surgeon can be directed by augmenting his vision reality by taking into account the readings and calculations and perform resection osteotomy of femoral the neck accurate, without being mislead, simultaneously adjusting intra operatively in real time the osteotomy depth and distance objectively, aiming always to measured preoperatively planed osteotomy features.
The combination of Augmented reality environment and real surgery with planes and rulers appearing in operative field intra operatively, aiding the ability of surgeon to perform precise osteotomies brings a new dimension in operational surgery. The ability to integrate live accurate measurements of distances and angles and also simultaneously estimating the range of depth cut before the actual cutting in augmented reality makes the app particularly useful especially in minimal invasive operational settings where by default the vision of structures is sacrificed.
The software is not for primary image interpretation. Any influence the operators in making decisions during operation remains Surgeons own responsibility and experience. A surgeon must always rely on his or her own professional clinical judgement when deciding whether to use a particular technique when treating a particular patient. App does not dispense medical advice. It is recommended that surgeons must be trained in the use before using it in real surgery.
