The Tanner-Whitehouse method is the bone age scoring system favoured by Paediatric Endocrinologists everywhere. It takes longer to do than the Greulich & Pyle, and we always put it off to the end of clinic because we have to find a computer and get the atlas out.

Now you can score it in clinic. Quickly. Bone Age contains a dictionary of the criteria to remind you of the grades for each bone - just select one for each bone and move on to the next. It will tell you when all the bones have been scored and generate a bone age (either TWII or TWIII) for the RUS or the carpal bones, or if you prefer TWII, a 'twenty bone' score as well.
