Arthroscopic Bilateral Autologous Iliac Crest Bone Grafting for Restoring Large Bipolar Bone Loss in Anterior Shoulder Dislocation.

In anterior shoulder dislocation, the bipolar bone defect is a severe condition that could impair the stability of the shoulder joint. The bone-grafting technique is an effective method to restore the glenoid defect. For the large defect on the humeral side, several studies have suggested the addition of remplissage procedure; however, there is no consensus. Thus, we describe a bilateral autologous iliac crest bone grafting for patients with severe bipolar bone defect that creates a native anatomical structure and microenvironment for tissue repair. This technique will provide a reliable choice in addressing anterior shoulder dislocation with severe bipolar bone loss.
