Abstract :
Background res of the glenoid frequently require surgical treatment. A comprehensive and reliable scapula classification system involving the glenoid fracture patterns is needed to describe the underlying pathology. The AO Scapula Classification Group introduces an appropriate novel system that is presented along with its inter-rater reliability and accuracy. als and Methods rative consensus process (involving a series of face-to-face meetings and agreement studies) with an international group of 7 experienced shoulder surgeons was used to specify and evaluate a scapular fracture classification system with a focus on fracture patterns of the glenoid fossa. The last evaluation was conducted on a consecutive collection of 120 scapular fractures documented by both plain radiographs and computed tomography scans including 3-dimensional surface rendering. Inter-rater reliability was analyzed with κ statistics, and accuracy was estimated by latent class modeling. s scapular fractures, 46 involved the glenoid (38%), with 38 classified as F1 articular rim fractures. The overall median sensitivity and specificity in identifying these fractures were 95% and 93%, respectively. Surgeonsʹ accuracy in classifying F1 fractures ranged from 86% to 100% (median, 94%). Subsequently, classification of simple F1 fractures resulted in a proportion of 36% of anterior rim fractures, 19% of posterior rim fractures, and 45% of short oblique fractures, with accuracies ranging from 85% to 98%. sion ew system for scapular glenoid fractures has proved to be sufficiently reliable and accurate when applied by experienced shoulder surgeons. Further validation of the most detailed system, as well as involvement of surgeons with different levels of training in the framework of clinical routine and research, however, should be considered.
