“…The stiffness was calculated (in N/mm) by applying an anteriorly directed quasistatic 80-N force [27][28][29][30][31][32] to the humeral head while measuring head translation on the glenoid with the optical motion-capture system. This was continued until glenohumeral dislocation occurred or until a soft-tissue end point was reached without dislocation (stability).…”

“…Significant glenoid defects lead to increased risk of recurrence following arthroscopic shoulder stabilisation techniques [1,2]. The choice of operative procedure for shoulder instability is predominantly based on the calculation of glenoid bone loss [3][4][5].…”

Purpose The main purpose of this study is to establish which of two methods is more reliable in glenoid assessment for instability in pre-operative planning. Accordingly, we have studied the intra-and inter-observer reliability of glenoid parameters with the use of two-dimensional (2D) and three-dimensional (3D) reconstructed computed tomography (CT) images. Methods One hundred glenoids were measured with the use of 2D-CT and 3D-CT (in 3D orientation) by two independent observers (one experienced and one inexperienced). Measurements were repeated after one week for 30 randomly selected glenoids. Results The intra-class correlation coefficient (ICC) for interobserver reliability was significantly greater for 3D-CT (0.811 to 0.915) than for 2D-CT (0.523 to 0.925). All intra-observer reliability values for 3D-CT were near perfect (0.835 to 0.997), while those for 2D-CT were less reliable (0.704 to 0.960). A dependent t-test showed that, for both observers, almost all glenoid parameters (except R and d) differed significantly (p < 0.05) between 2D and 3D measurement methods. Conclusions Therefore, it can be concluded that 3D glenoid reconstructions are more reliable for glenoid bone loss assessment than 2D-CT. The results suggest that quantifying a glenoid defect with the use of 2D image only-even if performed by an experienced orthopaedic surgeon-is prone to errors. Differences in measurements between and within observers can be explained by plane setting and identifying glenoid rim in 2D -C T. Accordingly, we recommend that glenoid measurements should be performed in 3D orientation using 3D reconstruction obtained from CT images for pre-operative assessments, which are crucial for surgical planning.

“…Cadaveric biomechanical studies have suggested that anteriorinferior glenoid bone loss accounting for 19% to 21% of the glenoid width significantly compromises the stability of soft-tissue repair alone. 19,20 However, lower percentages of "subcritical" bone loss have been correlated with inferior clinical outcomes in the setting of arthroscopic soft-tissue stabilization. 14 According to the glenoid track concept, as glenoid bone defect size increases, the glenoid track decreases in width and increases the probability that a Hill-Sachs lesion can engage the glenoid rim.…”

Anterior glenohumeral instability is a common clinical entity, particularly among young athletic patient populations. Nonoperative management and arthroscopic treatment of glenohumeral instability have been associated with high rates of recurrence, particularly in the setting of glenohumeral osseous defects. Coracoid transfer, particularly the Latarjet procedure, has become the treatment of choice for recurrent anterior glenohumeral instability in the setting of osseous deficiencies greater than 20% to 30% of the glenoid surface area and may also be considered for the primary treatment of recurrent instability in the high-risk contact athlete, even in the setting of limited osseous deficiency. The following Technical Note provides a diagnostic approach for suspected glenohumeral instability, as well as a detailed description of the congruent-arc Latarjet procedure, performed with a deltoid split, with its postoperative management.
