Bony deficiency of the anterior glenoid rim may signiﬁcantly contribute to recurrent shoulder instability. Today, based on clinical and biomechanical data, a bony reconstruction procedure is recommended in patients with bone loss of greater than 20–25% of the glenoid surface area. Recent advances in arthroscopic instruments and techniques presently allow minimally invasive and arthroscopic reconstruction of glenoid bone defects and osteosynthesis of glenoid fractures. This article underlines the role of glenoid bone deficiency in recurrent shoulder instability, provides an update on the current management regarding this pathology and highlights the modern techniques for surgical treatment.
