Bone Ninja App for iPad
Bone Ninja is an iPad app teaching tool developed by Dr. Shawn Standard and Dr. John Herzenberg at the International Center for Limb Lengthening. It is designed to help surgeons learn to analyze long bone deformities by drawing lines, measuring angles, measuring lengths, and manipulating bone fragments to make osteotomies. There have been over 11,850 downloads of the Bone Ninja app since it was released in 2012.
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.
The analysis of the radiographs is based on methodology taught for more than two decades at our annual Baltimore Limb Deformity Course. 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. Click here to view the Bone Ninja User Guide.
