BackSCNR vs PJKPredict

BackSCNR (Back Scanner) is a scoliosis screening and monitoring support tool designed to aid in the management of Adolescent Idiopathic Scoliosis (AIS). Using advanced Surface Topography (ST), the app provides a radiation-free and non-invasive way to assess the 3D shape of the human torso, offering a safe alternative for frequent monitoring without exposure to harmful X-rays. Developed through years of leading academic research, BackSCNR is registered with Health Canada as a Class I Software as a Medical Device (SaMD). It is intended for use in individuals aged 10–18 years to assist clinicians in quantifying torso asymmetries and estimating curve angles associated with AIS. Key Features: - Flexible 3D Torso Capture: Capture high-accuracy 3D scans using either the Structure Sensor accessory or your iPhone’s built-in TrueDepth camera. - Asymmetry Analysis: Aids in identifying and tracking torso asymmetries over time. - Clinical Support: Provides detailed metrics, including estimated Cobb angles and deviation color maps, to support clinical decision-making. - Rapid Results: Upload and process models to receive analysis within minutes on our secure web platform. How it Works: 1. Select Your Hardware: The app automatically detects if a Structure Sensor is connected and will default to it for scanning. If no sensor is detected, the app defaults to the iPhone’s TrueDepth camera. 2. Capture the Scan: Follow the in-app guidance to take a 3D scan of the patient's torso. 3. Analyze & Report: Upload the data to the secure BackSCNR website for automated analysis and reporting. Compatibility: - TrueDepth:** Compatible with TrueDepth-enabled iPhones (iPhone X and newer). - OS: Supported on modern iOS devices (iPhone X and later) and compatible iPads. - Sensors: Optimized for Structure Sensor 3; also supports Mark II and Pro models.

Always seek the advice of a physician or other qualified healthcare provider with any questions regarding a medical condition. Use of the device for diagnosis should only be done in consultation with a qualified healthcare professional.

PJKPredict is an institutional-grade biomechanical simulator and clinical decision-support application engineered for orthopedic spine surgeons, neurosurgeons, and spine fellows managing adult spinal deformity (ASD). Key Capabilities: • Lafage-ISSG Clinical Score: Evaluates patient demographics, age, BMI, prior osteotomies, and pre-op deformity severity. • Yilgor Global Alignment and Proportion (GAP) Score: Full 5-component biomechanical analysis (RPV, RLL, LDI, RPA, Age Factor) categorizing constructs into Proportioned, Moderately Disproportioned, or Severely Disproportioned with predicted mechanical failure probability. • 120 FPS Sagittal Spine Canvas: Real-time vector spine morphing reflecting patient Pelvic Incidence, planned Lumbar Lordosis, and Thoracic Kyphosis with SVA plumb line and hardware rod rendering (Cobalt-Chrome, Titanium, Stepped Transition). • Dynamic UIV Stress Heatmap: Real-time comparison across all candidate upper instrumented vertebrae from T1 to L3. • Adaptive Evidence Calibration Engine: Evaluates peer-reviewed literature and dynamically updates predictive model weights according to Evidence Level (RCTs, prospective cohorts, OR/HR) with full clinical provenance. Disclaimer: PJKPredict is an educational clinical decision-support tool. It does not replace individualized surgical judgment or clinical diagnosis.
