Evaluation of functional spinopelvic imaging in lateral radiographs in sitting and standing positions is of importance, especially in patient before total hip replacement surgery. Patients with concomitant hip and spine pathology undergoing primary total hip were identified as being at high risk for dislocation. Instability-prone patients arhtroplasty (THA) should appropriately assessed for the presence of deformity and abnormal spinopelvic mobility. The preoperative planning for THA should encompass evaluation of functional spinopelvic imaging in lateral radiographs in sitting and standing positions. Before planning cup position the surgeon should taken into account also anterior pelvic plane (APP) the coronal (functional) plane and the anterior pelvic plane tilt APPt or pelvic tilt and abnormal spinopelvic mechanics from standing to sitting. The App is software aimed for orthopaedic surgeons, and allow to: -securely import medical images directly from the camera or stored photos. - mark certain points at the image of X-ray, and calculate at once the anterior pelvic plane tilt (APPt) or pelvic tilt , Pelvic incidence (PI), Sacral slope (SS), Lumbar lordosis (LL), Pelvic incidence Angle (PI) minus Lumbar lordosis Angle (LL)(PI–LL). -to classify the patient into one of four Categories of the Hip-Spine Classification (1A,1B,2A,2B) by integrating spinal alignment (spinal deformity defined at PI-LL mismatch >10 degree(1) -cases are categorised to group-specific recommendations for acetabular cup position respectively thus with minimal measurements will effectively identify the complex “hip-spine” THA patient at high risk for postoperative instability (1). -save the planned images, for later review or consultation.The measured values are exported as txt file, ready to print or to input as cells to excel for research. -in case of wrong selection powerful undo feature is present. -According to measured parameters in standing and sitting lateral x- rays - based n a busy everyday practice, app offers a convenient way to perform radiographic measurements for spine, at the spinopelvic juncture - combing sitting and standing X-Rays, in a blink of an eye in front of your screen. The build in features of the app, allows results to be categorized and may help identify the complex “hip-spine” THA patient at high risk for postoperative instability and helps planning the optimum cup placement. All information received from the software output must be clinically reviewed regarding its plausibility before patient treatment! App indicated for assisting healthcare professionals. Clinical judgment and experience are required to properly use the software.The software is not for primary image interpretation.
