Loss of the sclerotic line of the glenoid on anteroposterior radiographs of the shoulder: A diagnostic sign for an osseous defect of the anterior glenoid rim

Radiographic sclerotic contour loss in the identification of glenoid bone loss

“…This radiographic finding was present to a lesser extent with smaller defects. Similarly, sclerotic contour loss was noted in glenoids with [21] found larger mean superoinferior and AP dimensions of glenoid lesions associated with radiographic loss of sclerotic contour compared to lesions associated with intact glenoid contours. However, area loss was not calculated.…”

The intra- and inter-observer reliability of the CT-scan based X index to quantify glenoid bone loss in chronic anterior shoulder instability and its impact on decision making

“…Sixty patients with X index C 0.4 were included. The mean age was 28 years (average [15][16][17][18][19][20][21][22][23][24][25][26]. There were 56 men and 4 women, with 40 right and 20 left shoulders.…”

“…According to the ISIS, the AP shoulder radiograph in neutral position was used in order to detect a loss in the SGL [20]. This assessment was done by the surgeon as a preoperative evaluation and was collected retrospectively from the medical file.…”

“…Several authors described different radiological methods of detecting and measuring these bony defects [2,5,20,26,27]. The loss of the anterior sclerotic glenoid line (SGL) in neutral rotation radiographs is currently widely used to detect anterior glenoid bone loss [20].…”

“…The loss of the anterior sclerotic glenoid line (SGL) in neutral rotation radiographs is currently widely used to detect anterior glenoid bone loss [20]. CT-scan measurement methods of anterior glenoid bone loss have been recently developed [4,17,24,29].…”
