Final answer:
The Bristow-Latarjet procedure is recommended when there is at least 25-30% bone loss on the Glenoid.
Step-by-step explanation:
The Glenoid is the socket of the shoulder joint. A Bankart lesion is a type of glenoid labrum tear, where the labrum is the ring of soft tissue that surrounds the Glenoid. The Bristow-Latarjet procedure is a surgical technique used to treat recurrent shoulder dislocations by moving a piece of bone from another part of the shoulder to the Glenoid, which helps stabilize the joint.
In terms of the percentage of Glenoid that must be involved to warrant a bone replacing procedure, it is generally agreed upon that if there is at least 25-30% bone loss on the Glenoid, a Bristow-Latarjet procedure is recommended. This amount of bone loss is considered significant enough to compromise the stability of the shoulder joint and require surgical intervention to prevent further dislocations.
