Joint and Bone algorithm is an orthopedic specific app with step by step guidelines for diagnosis and treatment for a large number of orthopaedic specific issue. It was created by the Joint and Bone Science Master Center in Tehran, Iran. This app is a terrific resource to help students, residents and supporting staff through easy to read algorithms regarding basic orthopaedic problems. The strength of this app is the content and development of almost 100 musculoskeletal algorithms. I applaud the developers for the breadth of their content. While I feel the content could be presented in a more interactive manner, the content and thought that went into the algorithms is impressive. Obviously there are some serious concerns regarding the accuracy and copyright of the algorithms, outside of this major issue the algorithms are well done.
