Coracoid graft osteolysis after the Latarjet procedure for anteroinferior shoulder instability: a computed tomography scan study of twenty-six patients

Background tarjet procedure has been advocated as an option for the treatment of anteroinferior shoulder instability in certain patients. However, progression of the transferred coracoid bone graft to osteolysis has been reported in the literature. We propose that the coracoid bone graft osteolysis could be one of the causes of failure of the Latarjet procedure. als and methods uted tomography scan analysis was done of 26 patients prospectively followed-up after the Latarjet procedure to determine the location and the amount of the coracoid graft osteolysis. s st relevant osteolysis was represented by the superficial part of the proximal coracoid, whereas the distal region of the coracoid bone graft, especially in the deep portion, was the least involved in osteolysis and had the best bone healing. sion knowledge, this is the first study to quantify and localize coracoid osteolysis after Latarjet procedure for anteroinferior shoulder instability using CT scan analysis. sion udy suggests that the bone-block effect from the Latarjet procedure may not be the principal effect in its treatment of anteroinferior shoulder instability in patients without significant bony defects.
