High rate of bone graft resorption found after Latarjet procedure for shoulder instability

Researchers of this study note that although the open Latarjet procedure provided significant improvement in clinical scores for patients with anterior shoulder instability and glenoid bone loss, 90.5% of patients showed graft resorption on CT at 1-year postoperatively.

Investigators studied 63 patients who underwent open Latarjet procedures performed during a 3-year period. At 1-year postoperatively, four independent surgeons evaluated the severity of graft resorption on CT scans using a four grade classification system. The evaluations were done twice every 3 months. In addition, patients were evaluated with American Shoulder and Elbow Surgeons (ASES), Constant-Murley and Rowe scores. Follow-up evaluations were conducted at 6 weeks, 3 months, 6 months, 1-year and yearly until last follow-up. Investigators were able to clinically evaluate 57 patients at 2-year follow-up.

Finding showed ASES, Constant-Murley and Rowe scores all significantly improved from preoperative values. Investigators noted the coracoid bone resorption incidence was high with an incidence rate of 90.5%. Of the 63 patients, six patients were classified with grade 0 coracoid resorption, 26 patients with grade I, 25 patients with grade II and six patients with grade III. Investigators found excellent interobserver reliability and intraobserver reliability for the classification system. ‒ by Monica Jaramillo
