Bone Ninja Sensei vs OsteoPlan

Bone Ninja is a teaching tool developed by two orthopedic surgeons who specialize in limb deformity correction: Dr. Shawn Standard and Dr. John Herzenberg. It is designed to help surgeons learn to analyze long bone deformities. Bone Ninja comes pre-loaded with radiographs of normal legs and deformed legs. You can analyze the provided cases or upload your own. Once your analysis is complete, you can then use the cut-out tool to try different osteotomy solutions. Suggested solutions for the provided cases are available for comparison. Bone Ninja includes tools for drawing lines, measuring angles, measuring lengths, and calibrating the magnification. The cutting tool allows you to manipulate one or more fragments to simulate correction of single or multilevel deformities. The analysis of the radiographs is based on methodology taught at our annual Baltimore Limb Deformity Course (BLDC), now in its 22nd year (DeformityCourse.com). We developed this app to supplement the BLDC and look forward to feedback from attendees and other users. Bone Ninja is not presented as a clinical tool, but rather an educational tool. It will not “automatically” analyze deformities. The student must first learn the methodology of analyzing and planning deformity correction in order to use Bone Ninja. Bone Ninja is a 21st century mobile alternative to pencil, ruler, goniometer, and paper. Bone Ninja will be periodically updated by adding more case examples, more explanations, and more tools. The name “Bone Ninja” is intentionally whimsical and reflects our philosophy of teaching as “infotainment.” Enjoy! Disclaimer The Bone Ninja App is designed for educational purposes only. The intent is to train physicians how to analyze long bone deformities. The Bone Ninja App is not intended to be used for medical diagnosis or treatment.

OsteoPlan is an all-in-one orthopaedic planning, measurement, operative note, and case management app for surgeons and trainees. Designed by an Orthopaedic Surgeon, it is built around real clinical workflows for planning, documentation, teaching, and follow-up. Measure coronal and sagittal limb alignment, classify knee phenotypes, plan osteotomies, simulate corrections, calculate wedge sizes, and document cases with structured images, notes, scores, follow-ups, and exports. All core tools are included free. Key Features Limb Alignment Analysis Measure HKA, MPTA, LDFA, JLCA, PTS, PDFA, SJLA, and other coronal/sagittal knee alignment parameters using point-based marking, draggable landmark labels, and visual axis display. CPAK Classification Use knee alignment measurements to generate CPAK classification with type-specific visual results. Osteotomy Planning Plan and simulate HTO, DFO, and Double-Level Osteotomy. Calculate correction angles, wedge sizes, predicted alignment, and visualize correction on radiographs. Clinical Measurement Tools Dedicated workflows for knee, shoulder, hip, spine, trauma, and general orthopaedic measurements. Spine Tools Measure Cobb angle, coronal balance, sagittal vertical axis, pelvic parameters, thoracic kyphosis, and lumbar lordosis. Trauma Tools Assess common trauma angles including distal radius parameters, Böhler’s angle, Gissane’s angle, Meary’s angle, Kite’s angle, Baumann’s angle, neck-shaft angle, acetabular index, and critical shoulder angle. Structured Case Storage Store patient details, BMI, clinical scores, images, intra-operative findings, post-operative records, OT notes, and follow-ups in organized folders. OT Notes & Templates Create structured operative notes with guided templates for common orthopaedic procedures, implant details, rehabilitation protocols, and review dates. Export & Backup Export annotated images, PDFs, OT notes, or complete case folders as ZIP files. Supports cloud backup options for safer data continuity. Designed for iPhone, iPad, and Mac, with Apple Pencil support on iPad.
