The TwinLoop FLEX Instrumentation System contains five different drill guides. The standard and reverse mouth drill guides are designed with a 12° or 25° curved tip and a straight option is also available. These guides are designed to enable the surgeon to reach farther around the glenoid rim to more securely position the anchor. In addition, the need to create an inferior anterior portal is eliminated, therefore helping to reduce the risk of damaging soft tissue adjacent to the inferior glenoid.
