Does the Dynamic Sling Effect of the Latarjet Procedure Improve Shoulder Joint Stability? A Biomechanical Evaluation

The Latarjet procedure, a transfer of the coracoid and the conjoint tendon, is commonly used to treat anterior glenoid bone loss due to instability. The transferred conjoint tendon is thought to provide a stabilizing sling effect; however, the significance of this mechanism is unknown. The purpose of this in-vitro study was to evaluate the effects of coracoid transfer, with and without conjoint tendon loading, on shoulder stability and range of motion (ROM).
