Sophisticated app for pre-operative planning of osteotomies and limb correction.
Although it has a catchy name and cute icon, Bone Ninja is neither a toy nor a game. This is a sophisticated and serious app created by the International Center for Limb Lengthening to teach planning for limb lengthening and alignment surgery. The app was primarily used as a tool for the deformity course that they host, and I advise that anyone interested in the app either take the course or watch one of the introductory lectures.
The app itself includes a library of images for practicing and learning. This includes both frontal and saggital plane views of limbs with various angular deformities. The user can also upload their own image. Once an image is selected, you enter the editing mode. The features are impressive, and include calibration and enhanced editing tools such as various select functions, linking options, the ability to free-cut the image, angular and length measurement tools and rulers, and more. It even has “hardware” icons that can be added to the images.
