Read full description

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.
