Recurrent glenohumeral instability is challenging to treat when large bony defects are present in the anterior glenoid and there is a large Hill–Sachs lesion. We present a case with extensive glenoid and humeral bone loss treated with open Latarjet procedure combined with posterior arthroscopic Remplissage. 3.5 years after surgery, there have been no dislocations or any subjective signs of instability. After half a year, the patient was able to return to work as an airline pilot. Constant score has improved from 33 to 74 and the Oxford instability score from 8 to 46. We find that in young patients with difficult instability combining the Latarjet and Remplissage is a good and replicable method.
