TotalHipArthroplastyToolboxAR 17+

Good surgical technique and accurate implantation of the components of total hip arthroplasty (THA) are critical factors for good performance and longevity of THA. Common complications like decreased range of movements, increased rates of impingement, wear rates, acetabular migration, recurrent dislocations, osteolysis, ‘squeaking, and early failure rates requiring early revision surgery are attributed mainly to poor operational techniques.
Although Computer-assisted navigation systems (CAOS) have been developed and explored in total hip arthroplasty (THA) and in our days is proven that improve the precision and help the Orthopaedic Surgeon during operation, remains expensive and time consuming modality available in a handful of orthopaedic centres worldwide. The apps take advance of augmented reality (AR) merged with Computer Assisted Orthopaedic Surgery (CAOS) techniques- and convert iPhones to handy navigational systems in which the surgeon can augment intra operatively the subjective reality. Also major guidelines extracted and distilled by international literature, converted in knowledge and expertise merged with AR, making readily available intra operatively during procedures.
The Applications included in Toolbox are merging Augmented reality with Computer Assisted Orthopaedic Surgery (CAOS) techniques and principles in effort to help an orthopaedic surgeon during operation without the need of expensive CAOS equipment. The TotalHipArthroplastyToolboxAR toolbox contains :
-a. NaviToolHip App. The app is a navigation tool in augmented reality (AR ) for improving intraoperative navigation during cup positioning in total hip arthroplasty. App can accurately help adjust objectively the anteversion and inclination of the cup either during sequently reaming or during final impaction of the cup accordingly
-.b. ScrewCupNaviAR App.The App developed for augmented reality (AR) helping the surgeon during operation to navigate and position of the screw properly in cup. The App increase the accuracy, during trans acetabular screw placement. Helps finding not only the optimal positions of screw-holes on cups but to allow also and predict safe screw trajectories courses -insertion depth in mm- avoiding bearings that could jeopardise periacetabular neurovascular and musculotendinous structures in real time objectively.
-c. FemurOsteotomyTHR App allows the surgeon to expedite intraoperatively in augmented Reality (AR )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.
-d. CupAnteversionInclinationApp The app offers in a simple standard AP pelvic radiograph, 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.(Widmer’s method) taking into account the pelvic tilt.
-e. AcetabularAnteversionApp The App computes the acetabular anteversion based on a pelvic AP radiograph without the need of CT. The angle of anteversion is calculated through the formula according to Heftis nomogram. The acetabular orientation (anteversion/retroversion) is determine , important to know before performing total hip arthroplasty.
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.
