Video Transcription

Video Summary

This presentation discusses a CT-based algorithm for preoperative planning of the Latarjet procedure used to treat critical anterior glenoid bone loss. The study developed a reproducible method to measure coracoid graft dimensions via CT scans, finding significant variability, especially thinner coracoids (<10 mm) in 75% of females. The classic Latarjet effectively restored up to 30% bone loss, but beyond that, the congruent arc modification might be necessary, despite risk of graft fracture in thin coracoids. The algorithm assists in selecting the appropriate technique to ensure a stable, on-track shoulder postoperatively, reducing surgical surprises.
