Aseptic glenoid loosening is the most frequent cause of revision and can be associated with severe cavitary, segmental, or combined glenoid bone defects. In this study, we describe a glenoid reconstruction technique using tricortical iliac crest graft supplemented with resorbable bone cement. We report on the results of this technique in 6 patients with an average follow-up of 15 months. The average Constant score improved from 36.8 to 59.8 points after revision. Subjectively, 5 of the 6 patients were satisfied with their results and 1 patient was disappointed. We observed satisfactory healing of the graft and maintained homogenous density of the graft in 5 of 6 cases. There was severe erosion of the graft in the case with poor healing and graft resorption, possibly due to a low-grade infection, although this was not proven. There was a partial erosion of the graft observed in 2 additional cases, whereas the remaining 3 cases had no, or only minimal, erosion. Although long-term follow-up is necessary, we have been pleased with the early results of this technique for glenoid reconstruction in the presence of severe glenoid bone loss, an extremely difficult and challenging surgical problem.
