Comminuted periprosthetic humeral fracture after reverse shoulder prosthesis.

Periprosthetic fractures represent a severe complication after joint replacement. A case of comminuted displaced humeral fracture around the stem of a SMR reverse shoulder prosthesis is reported. The patient was a 81-year-old lady who had had a total shoulder replacement 28 months previously. The surgical solution consisted of a partial revision of the modular implant with conservation not only of the glenoid component but also of the prosthetic humeral body, which was well fixed in the humeral metaphysis. The humeral stem was removed and a long uncemented revision stem was implanted providing fracture stabilisation and allowing early mobilisation.
