Long-term outcomes of coracoid bone block osteolysis: case report

Latarjet procedure is reliable and reproductible procedure for treatment of anterior shoulder instability. Results are durable but complications can occur: neurological injury, non-union, infection, stiffness, osteolysis of coracoid bone block, recurrence of dislocation, osteoarthritis. We present the case of two patients with complication not described in the literature: osteolysis of the neck of the scapula around screws discovered at 8 and 20 years after initial surgery. These patients presented with previous pain which motivated consultation. Imaging showed coracoid bone block osteolysis, extensive geode weakening articular surface of scapular glenoid, around screws which are not bi-cortical. Screws were removed, osteolysis was filled with iliac cancellous bone graft and joint capsule was re-tensioned. Results of this procedure at one year were clinical and radiological satisfactory.
