A case of a periprosthetic humeral fracture in which early bone union was achieved through concomitant use of teriparatide

The Mayo type 2 periprosthetic humeral fractures are difficult to treat because they may involve a loosened stem. We report a case of a periprosthetic humeral fracture after unlinked-type total elbow arthroplasty in which early bone union was achieved through a combination of locking plate fixation and teriparatide therapy. Although the osteogenesis-promoting effect of teriparatide on fresh fractures is still controversial, we considered that administration of teriparatide is meaningful for the treatment of potentially refractory fractures.
