WhereMyCup

WhereMyCup is a professional spinopelvic measurement aid for trained healthcare professionals, clinical teams, educators, researchers, and supervised users.

The app supports a standing and sitting radiographic workflow. Users can load or capture an authorized image, place guided anatomical points with a concentric-circle selector and centre crosshair, review measurement overlays, and export annotated images or text reports.

Key features:
- Separate standing and sitting image workflow.
- Floating guide showing the next anatomical point.
- Concentric pointer with centre-crosshair registration.
- Double-tap or Select to register the active point.
- Local calculations and overlays for APP tilt, lumbar lordosis, sacral slope, pelvic incidence, PI-LL mismatch, and related classification text.
- Undo, reset, final result review, annotated image export, and report sharing.
- In-app consent, privacy, terms, support, and professional-use reminders.

Camera compatibility:
The camera feature is optional and requires an Android device with a compatible camera
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 -Flatback deformity and mobility (stiffness- Defined as no change in Sacral Slope -SS between standing and sitting positions -ΔSS<10 deg )
-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
-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.
