Latarjet/Coracoid Process Transfer for Glenoid Deficiency

Traumatic glenohumeral dislocation or chronic glenohumeral dislocation/subluxation can cause damage to or fracture the glenoid rim. The resulting bone loss leads to anterior instability that cannot be corrected with soft tissue/labral repair alone. Thus, a Latarjet/Coracoid Process Transfer is performed based on pre-operative diagnostic imaging and arthroscopic evaluation of the percentage of bone loss. The increase in bone area by securing the coracoid to the glenoid and resultant soft tissue sling from tendon attachments on the coracoid leads to a stabilized glenohumeral joint.

Congruent Arc Latarjet

The Glenoid Bone Loss Set includes unique instrumentation and implants to make the open Latarjet technique more consistent and repeatable. TheCongruent Arc Latarjet Technique developed by Dr. Stephen Burkhart, Dr. Ian Loand Dr. Sven Lichtenberg involves dissecting the CA ligament and pectoralis minor from the coracoid and performing a coracoid osteotomy. A grasping CoracoidDrill Guide is used to prepare two parallel holes in the coracoid graft which then mate with one of the Glenoid Parallel Drill Guides. The cannulated guide allows the graft to be positioned on the glenoid while guide wires are placed through the graft and into the glenoid. Self-drilling, self-tapping 3.75 mm titanium cannulated screws are then placed over the guide wires securing the graft into position.
