DynamicHipVision

DynamicHipVision is a public educational app that turns an authorized pelvic teaching image into an interactive landmark-geometry and mathematical-model experience for Apple Vision Pro. No organization affiliation, invitation, account, private server, or special registration is required. Every user receives the same standalone app. GUIDED 19-LANDMARK WORKFLOW Import an authorized, preferably de-identified image from Photos or Files. Enter non-identifying reference-series values, calibrate the image with a visible marker, and follow the exact 19-landmark sequence. A stable concentric-circle selector supports precise placement, pan, zoom, one-unit nudging, undo, replacement, and next-point guidance. TRANSPARENT MODEL OUTPUTS After a complete sequence, the app displays image-derived geometry and transparent mathematical model outputs, including: - calibration scale; - centre-edge and supporting-angle descriptors; - acetabular-depth ratio; - lever-arm relationships; - R/G5 and P/G5 model indices; - model contact-area estimate; - model-equivalent force term; - reference-series comparisons; - sigma and theta graphs. DynamicHipVision does not directly sense force or pressure. These outputs are estimates derived from the selected image, calibration, reference-series inputs, user-placed landmarks, and disclosed equations. REVERSIBLE MANUAL GEOMETRY DEMONSTRATION Use a separate manual scenario to explore how model outputs respond when the user changes femoral position or orientation. This demonstration is reversible and never overwrites the original 19 landmarks or baseline result. The app does not choose a correction, rank alternatives, recommend a procedure, select an implant, or provide a patient-specific target. NATIVE SPATIAL REVIEW Open a native visionOS volume or immersive space to study: - registered and manual-scenario landmarks; - femoral-head spheres and contact cylinders; - anatomical lines and reference axes; - cyan model-load vectors; - red model-pressure and edge-sensitivity vectors; - live updates after a user-controlled scenario change. The model can be inspected from different viewpoints, and floating controls can be hidden so the geometry remains unobstructed. X and Y are calibrated from the image. Depth and axial rotation are explicit visualization assumptions; the result is not CT, MRI, biplanar reconstruction, or patient-specific volumetric anatomy. LOCAL-FIRST AND USER-CONTROLLED Images, landmarks, calculations, local recovery data, and scenarios are processed within the app. Nothing is automatically uploaded to Orthopractis. Text, CSV, and annotated-image exports are created only when the user requests them. IMPORTANT SAFETY NOTICE DynamicHipVision is educational landmark-geometry, mathematical-model, and spatial-visualization software. It is not intended for diagnosis, treatment, surgical planning, procedure or implant selection, component prescription, or navigation. Its outputs are model-derived estimates and are not direct physiological, cartilage, bone, or implant measurements. Do not use an app result as the sole basis for patient care. Always seek advice from a qualified physician in addition to using this app and before making any medical decision. - Public access: no account, invitation, organization affiliation, private server, or external entitlement is required. - Public Release safety boundary: operation-specific optimization, treatment ranking, best-candidate selection, guided therapeutic correction, implant/component targeting, and automatic candidate application are not available. - A Release-only public-education compilation condition prevents research controls from being enabled by launch arguments. - Legacy recovered planning state is cleared before the public workspace opens. - Reference inputs are now labelled as non-identifying reference-series values rather than as a patient profile.
