BoneGauge vs Bone Ninja Sensei

BoneGauge allows you to approximate an individual's bone density and quality from a mobile platform. BoneGauge helps you make measurements of cortical thickness of the second metacarpal from either hand or wrist x-rays. Use your smart phone camera to take a photo of the second metacarpal on an x-ray, or make measurements from an image saved in your photo library. BoneGauge accurately calculates 2nd metacarpal cortical percentage (2MCP) in a semi-automated fashion. 2MCP has been shown to correlate with hip bone mineral density and T scores from DXA scans. Measurements made in the app will be uploaded to a central database. When combined with a patient's age, gender, and DXA score, past measurements will also help the improve the accuracy of future measurements. This app allows you to estimate an individual's global T score in an office or hospital setting, by simply taking a photo of the 2nd metacarpal. While this measurement may not completely replace DXA, it may help a clinician screen a patient's bone quality to assist in treatment decisions and determine who may benefit from further bone density testing or osteoporosis treatment.

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.
