The GLENOID BONE LOSS SYSTEM offers you a range of technique, alternatives to match your preferred decision-making process and procedural style: Using a fresh bone graft, treatments like the mini-open Latarjet or arthroscopically assisted bone block are both intended to help restore joint stability. Two approaches to addressing glenoid bone loss within one comprehensive system. An approach that is intended to be precise and effective at every stage for the best possible location of the bone graft.
Arthroscopic Latarjet – Bone block Tray
First introduced by Michel Latarjet in 1954 and made famous by Walch and Patte, coracoid transfer to treat anterior shoulder instability is becoming more and more common in cases of glenoid deficit and in revision anterior stabilization.
The method offers three benefits:
- It enables the replacement of lost glenoid bone (static bone effect)
- By bringing the conjoined tendon closer to the joint and lowering the inferior section of the subscapularis, it strengthens the weak and strained inferior glenohumeral ligament (dynamic sling or seatbelt effect)
- It enables “triple locking” of the shoulder when combined with the reattachment of the labrum and capsule. With a low rate of recurrent instability, a high rate of returning to sports at preinjury levels, and a high rate of patient satisfaction, the surgery produces positive results.
We have created a novel surgical technique and fixation method that uses a guided surgical approach for graft positioning and the use of specific suture buttons for fixation in an effort to make the arthroscopic Latarjet procedure safer and to lessen complications associated with the traditional screw fixation. In a recent clinical trial, we assessed the computed tomography (CT) accuracy of graft location and healing in 76 patients who were followed prospectively.
We have shown that:
- the coracoid bone graft can be precisely positioned with the use of the guiding technique
- cortical button fixation is an alternative to screw fixation that allows predictable and reproducible bone union and minimizes complications reported with screw fixation
- neurological and hardware complications, traditionally reported with screw fixation, have not been observed with this guided technique and novel fixation method.
