Description[edit | edit source]
The Latarjet procedure is a possible surgical procedure to treat patients with anterior shoulder instability and accompanied bone loss. It involves transferring the coracoid process and its attached conjoint tendon to the anterior glenoid rim. In 1954, Latarjet first proposed the transfer of the coracoid tip by suggesting that the horizontal limb of the coracoid process be fixed to the anteroinferior margin of the glenoid with a screw[1]
Biomechanics of Latarjet[2] -
- The conjoint tendon acts as a sling to the inferior subscapularis and anteroinferior capsule when the arm is abducted and externally rotate.
- The addition of bone to the glenoid rim increases the anteroposterior (AP) osseous diameter.
- The inferior capsule is reinforced with a portion of the coracoacromial ligament.
A study evaluated the contribution to stability of the bone block, sling, and capsule repair and concluded that the sling effect provided 76-77% and capsule 23-24% of the stability at the end-range arm position and the sling contributed 51-62% and the bone block 38-49% at the mid-range position.[3] This is known as the triple blocking effect of the Latarjet procedure, and it should be noted that each portion of the procedure contributes to the overall stability of the GHJ.
Indication[edit | edit source]
The Latarjet operation employs a triple blocking mechanism, including lengthening the glenoid arc by adding a coracoid graft to the anterior glenoid rim. In the presence of significant glenoid bone loss, various bone-block methods have been used, most commonly the open Latarjet procedure[4]
- Instability with glenoid bone loss
- Combinations of glenoid and humeral bone loss
- Complex soft-tissue injury
- Revision of a Bankart repair
- Patients engaged in high-risk sports (climbing, rugby) or occupations (carpentry), or who have a high risk of recurrence due to the intensity and action of their activity (throwers), are ideal candidates for the Latarjet procedure
