Arthroscopic Technique for Bone Augmentation With Suture Button Fixation for Anterior Shoulder Instability

Area of Science:

• Orthopedic Surgery
• Arthroscopic Shoulder Surgery
• Bone Grafting Techniques

Background:

• Recurrent shoulder instability is often linked to glenoid bone loss.
• Current bone graft augmentation methods (autograft, allograft) have limitations, including screw fixation challenges like medial portal requirements and osteolysis risk.
• Suture button suspensory fixation is established for iliac crest grafts but not for osteochondral grafts.

Purpose of the Study:

• To describe a novel arthroscopic technique for glenoid bone augmentation using distal tibial allograft.
• To evaluate the feasibility and technical aspects of using suspensory suture button fixation for osteochondral allografts in the glenoid.

Main Methods:

• Arthroscopic glenoid bone augmentation using a distal tibial allograft.
• Application of suspensory suture button fixation for graft securement.
• Detailed description of the surgical technique, including portal placement and fixation method.

Main Results:

• Successful arthroscopic fixation of a distal tibial allograft to the glenoid using suspensory suture buttons.
• Demonstration of a technically viable alternative to traditional screw fixation.
• Potential to overcome limitations associated with screw fixation, such as medial portal needs and osteolysis.

Conclusions:

• Arthroscopic distal tibial allograft glenoid augmentation with suspensory suture button fixation is a feasible technique.
• This method offers a viable alternative for managing glenoid bone loss and shoulder instability.
• Further studies are warranted to assess long-term outcomes and compare with existing methods.
