CASE
We describe 2 patients who sustained a periprosthetic humeral fracture with a loosened long-stemmed Coonrad-Morrey total elbow prosthesis. As noted in the literature, the success rate for a major revision with use of strut grafts is around 70%; therefore, both cases were managed without revision of the prosthesis. A submuscular locking plate was placed following typical fracture fixation principles. Screws that interfered with the humeral stem and the distal flange stabilized both the distal fragment and the humeral stem.
CONCLUSION
At 2 years postoperatively, both fractures had healed, with increased endosteal bone stock. In each case, the prosthesis was successfully salvaged, and radiographic reconstitution of the implant-bone interface was noted after 2 years.
