Abstract:
Shoulder joint instability can lead to bone loss on both the glenoid side and the posterior part of the humeral head, known as bipolar bone loss. To restore glenoid defects, bone procedures like the Latarjet operation or free bone block transfer from the iliac crest are the primary options, restoring defects of up to 25% to 30%. However, in some cases, the glenoid defect may exceed 40%. This article discusses a unique technique for restoring glenoid bone defects up to 50%, using 2 bone grafts-a free graft from the iliac crest and the coracoid process with conjoint tendon complex. This technique is called "double block sandwich technique."
