This app, available only for iPhone and Android, is marketed as a “buzzword” study guide for the orthopaedic in-training exam (OITE). The app is divided into 4 sections: index, about, quiz, and contact. The index lists 51 buzzwords, such as zebra lines, throckmorton sign, sausage digit, pancake vertebra, etc. Unfortunately, when testing on an iPhone 4S device the content did not load for all of the content sections resulting in a blank screen. For screens in which content did load, images required up to 30 seconds to load, and text often required 10 seconds to load. The information provided for each topic is brief (2-5 sentences). No references of additional information is provided for any of the topics. The quiz section includes a gallery of thumbnail images that can be selected. Once again, the images take up to 30 seconds to load, thereby negating the purpose of the app for quickly reviewing buzzwords. In addition, the answers to the image pathology would not appear, and in some cases the images did not appear at all. The contact section provides a phone number, email and website: www.bonetumor.org. Interestingly, the site appears to be an incredibly detailed, expansive, and valuable listing of bone tumors and their presentation, diagnosis, and treatment accompanied by xray and pathologic images. Overall, this app appears to address a need among residents for OITE studying, however the implementation ranges from painfully slow to entirely non-functional, rendering this app useless at this point. I do hope that future versions become more stable and useful since this is a great idea for OITE studying.
