Summary
Regional bone density variations exist in Favard E3 type glenoids, with higher densities found in the superior-anterior periphery. This finding may help optimize implant design and reduce loosening in reverse total shoulder arthroplasty.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Radiology
Background:
- Favard E3 type glenoids exhibit superior and global erosion patterns.
- Reverse total shoulder arthroplasty is a common treatment, but implant loosening is a concern with severe bone loss.
- Regional bone density variations in E3 glenoids are not well understood.
