A multiplanar tomographic modeling–based comparison of coracoid process transfer techniques for anterior shoulder instability
Aims: This study aimed to compare the standard and congruent arc Latarjet techniques in anterior shoulder instability using a multiplanar computed tomography–based modeling approach, with particular focus on coracoid process morphology, glenoid reconstruction capacity, and graft contact surface area.
Methods: A total of 200 patients were included for coracoid measurements and 156 patients for glenoid measurements. Coracoid length, width, and thickness were evaluated, and glenoid width was measured on computed tomography images. The potential glenoid bone defect reconstruction capacity and graft to glenoid contact surface area were calculated for both techniques. Sex-based anatomical differences were also analyzed.
Results: Coracoid dimensions were significantly larger in males than in females. The congruent arc Latarjet technique allowed reconstruction of a larger proportion of the anterior glenoid bone defect (mean 55%) than the standard Latarjet technique (mean 37%). In contrast, the standard technique provided a larger contact surface area between the transferred coracoid graft and the glenoid (452±126 mm² vs. 292±105 mm², p<0.001). Smaller coracoid dimensions, particularly in female patients, were associated with a smaller graft to glenoid contact area and the need for smaller fixation screws, which may reduce the mechanical stability of graft fixation.
Conclusion: While the congruent arc Latarjet technique allows reconstruction of larger glenoid bone defects, the standard technique offers a greater contact surface area that may favor graft healing and fixation stability. Coracoid process morphology, especially in smaller-sized coracoids, should be considered during surgical planning. Preoperative evaluation of coracoid process dimensions may help optimize technique selection and reduce the risk of complications.
