Description

This video recording details a surgical procedure for addressing chronic instability of the right AC joint in a 43-year-old male patient. The surgeon begins by explaining the patient's condition, which appears to be a grade three dislocation based on imaging, although there are clinical indications of grade four instability. The procedure is explained step-by-step, starting with positioning the patient in the 'beach chair' position for optimal access.



The surgical approach involves making an incision along the underside of the clavicle centered on the coracoid for an extensile exposure, vital in addressing the AC joint and associated ligaments. Throughout the procedure, careful dissection and exposure of the clavicle, coracoid, and CA ligament are emphasized, as well as the necessity to manage scar tissue and redundant tissue resulting from the chronic dislocation.



The technique outlined includes drilling holes in the clavicle and coracoid, creating a socket for the CA ligament, and using a tightrope construct for ligament stabilization. The surgeon ensures the anatomical repositioning of the clavicle and secures the superior capsule with sutures. The procedure concludes with the patient being placed in a sling for four weeks to protect the repair before resuming full activities. Each technical detail underscores the surgeon's cautious approach to achieve a secure repair while minimizing complications.
