"ICODE Hip US Calculator": a mobile phone aid for screening with Graf's sonographic technique.

Aim: Aiming to offer a diagnostic tool to aid examiners with correct hip typing and decision-making about patient management, members of the Board of the International Interdisciplinary Consensus Committee on DDH Evaluation (ICODE - https://www.icode.expert), introduced the cross-platform mobile application (Android and iOS) called "ICODE Hip US Calculator". Material and methods: The examination steps of Graf's hip sonography technique were converted into computer code and formed the basis for the development of a mobile phone application. An algorithmic approach, based on a series of conditional sentences, was followed for the development of the application (e.g. if … and … or … then). Coding of the algorithm was carried out by a Greek software development company. Results: A cross-platform mobile phone application which calculates Graf's hip type (according to the date of birth, the date of examination, and the alpha and beta angles) was constructed. The calculated hip type is then linked to simple management recommendations (discharge, rescan, refer). Conclusions: "ICODE Hip US Calculator" may be used by trained health professionals to help them decide upon the hip type and the management of the baby after the scan. Hip typing is precisely calculated, and management proposals are simple and straightforward. This means that the application may be used in screening settings to help with patient management, increase the examiner's confidence, and improve patient flow.
