Significant glenoid bone loss linked with less osteolysis of the coracoid bone graft after Latarjet procedure

Results of this study highlight the role of glenoid bone loss in osteolysis of the coracoid bone graft following Latarjet procedures.
Researchers followed 34 patients treated with a mini-plate Latarjet procedure. Patients who had glenoid bone loss greater than 15% were placed into group A, while patients with no glenoid bone loss were in group B. All patients underwent a CT scan evaluation with 3-D reconstruction so researchers could evaluate coracoid bone graft osteolysis.
According to CT scan analysis, group A and B experienced different distributions of osteolysis. Statistical analysis also showed a significant difference between group A and B for proximal/lateral/superficial, proximal/medial/deep, distal/lateral/superficial and distal/lateral/deep. Compared with group B, researchers found the coracoid grafts in group A showed less osteolysis on average.
“This study allows us to conclude that the bone block is important in restoring the osseous arc and therefore plays a role in cases with significant glenoid bone loss,” the researchers wrote in the study. “In cases without significant bone loss, the graft undergoes so much osteolysis that the stabilizing effect of the Latarjet procedure must be due to other components of the technique (sling effect, capsular effect).”
