Abstract Anterior shoulder dislocation is associated with glenoid cavity and humeral head bone disorders. A Hill–Sachs lesion is a depression fracture of the humeral head, while a bony Bankart lesion is a fracture of the glenoid, both lesions represent bipolar bone loss, even though many diagnostic approaches have been devised to quantify bipolar bone loss, there is no universal agreement about how to measure glenohumeral bone loss. Many of these approaches require expensive software to assess these combined bone anomalies, which is not yet available in clinical settings. Objectives: First, examine the Clock method’s intra- and inter-observer reliability; second, assess the Clock method’s correlations with existing bone loss measurement methods, as well as with the results. Study Design: This study was conducted in a crosssectional manner. The research was carried out at the Suez Canal University Hospital in Ismailia, Egypt, in the CT unit of the Radiology department. We studied 16 individuals with recurrent anterior glenohumeral instability and eliminated patients who had no apparent bone loss on CT images. All subjects underwent a CT scan with a 16-slice scanner, the Activion 16 version TSX-031A-2012, and standard accessories (Toshiba Medical Systems). The Glenoid Ratio, Humeral Head Bone Deficit, Humeral Ratio, Combined Clock Method, Glenoid Clock Method, and Humeral Clock Method were the areas of interest in our research. |
