Case:
A 68-year-old male, status post revision right reverse total shoulder arthroplasty (RTSA) for periprosthetic fracture, suffered a periprosthetic joint infection necessitating 2-stage revision. Imaging revealed 8.6 cm of ipsilateral proximal humeral bone loss (PHBL) including loss of the greater and lesser tuberosities. A 2-stage revision was performed using an antibiotic spacer, followed by a custom long-stem RTSA for definitive reconstruction. Two years postoperatively, the patient had significantly improved pain and functional range of motion.
Conclusion:
Custom long-stem RTSA could serve as a potentially viable reconstructive option in patients with severe PHBL.
