The Biomet Orthosize software is indicated for assisting health care professionals with the pre-operative planning of orthopedic surgery. The application allows for overlaying of prosthesis templates on radiological images, and includes tools for performing measurements on the image and for positioning of templates. The Biomet Orthosize app is not intended to replace the desktop application. The Biomet Orthosize app was designed as a companion app to enable the user to review and/or modify images that have previously been saved from the Biomet Orthosize desktop application. The Biomet Orthosize software requires all users to register an account with Biomet, accept the User Agreement, and is designed to template only Biomet products. The system allows surgeons to provide sales representatives with access to patient information, as part of the patient care process, for surgical planning preparation. However, surgeons are ultimately responsible for implant selection. Surgeons will need to provide Biomet with written permission for specified sales representative(s) to access patient data in furtherance of the care of such patient. Such permission requests should be emailed to orthosize@biomet.com. Visit www.orthosize.com to register for a user account.

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.
