BoneXpert

by Visiana

AI Application
Low Confidence

BoneXpert is software that reads a child's hand X-ray, used in hospitals by radiologists, radiographers, endocrinologists and nurses. The vendor says it determines bone age autonomously by the Greulich-Pyle and Tanner-Whitehouse 3 methods, and also reports a Bone Health Index and Percent Adult Height, for patients up to 21 years old. It automatically rejects images it cannot analyse, such as a wrong hand pose, heavy post-processing or abnormal bone morphology, and the vendor says a radiologist should then assess the image. The vendor says the analysis needs no supervision by an expert, but also that its results must not be used as the sole basis for diagnosis, so a clinician interprets the reported bone age. BoneXpert Server runs on hospital hardware and exchanges images with the PACS and RIS; BoneXpert Online processes anonymised images on Visiana's own server, whose location is not stated. Each analysis makes a handshake with a central licence server.

Instructions for Use
Visiana states BoneXpert is for DICOM hand radiographs of patients up to 21 years, used by healthcare professionals; bone age ranges are 0-19 years (boys) and 0-18 (girls) for Greulich-Pyle and 2-16.5 (boys) and 2-15 (girls) for TW3; it is 'Contraindicated for use in children with achondroplasia'; images with severely abnormal anatomy or excessive post-processing may not be accepted (about 1%); and 'BoneXpert results must not be used as the sole basis for diagnosis' (https://bonexpert.com/ce-mark/, read 2026-10-20). The BoneXpert Online IFU v1.1 (May 2021) adds that ethnicity is not considered, that radiographs recorded on film must not be analysed, that the Bone Health Index is mainly for research use, and that rejected images should be assessed by a radiologist (https://visiana.zohodesk.eu/portal/en/kb/articles/bonexpert-online-instructions-for-use, read 2026-10-20).
