Abstract

Abstract : Quantifying bone loss is important to decide the best treatment for patients with recurrent anterior glenohumeral instability. Currently, there is no standard method available to make a precise evaluation of the Hill–Sachs lesion and predict its engagement before the surgical procedure. This literature review was performed in order to identify existing published imaging methods quantifying humeral head bone loss in Hill–Sachs lesions. Searches were undertaken in Scopus and PubMed databases from January 2008 until February 2018. The search terms were "Hill-Sachs" and "measurement" for the initial search and "Hill–Sachs bone loss" for the second, to be present in the keywords, abstracts and title. All articles that presented a method for quantifying measurement of Hill–Sachs lesions were analysed. Several methods are currently available to evaluate Hill–Sachs lesions. The length, width and depth measurements on CT scans show strong inter and intra-observer correlation coefficients. Three-dimensional CT is helpful for evaluation of bony injuries; however, there were no significant differences between 3D CT and 3D MRI measurements. The on-track off-track method using MRI allows a simultaneous evaluation of the Hill–Sachs and glenoid bone loss and also predicts the engaging lesions with good accuracy.
