Shoulder Arthroplasty for Patients With Proximal Humeral Paget's Disease.

Poorly controlled Paget's disease leads to excessive blood loss following total hip arthroplasty. The effect in shoulder arthroplasty is unknown. The authors reviewed 3 patients with Paget's disease involving the proximal humerus, comparing them with 17 patients with Paget's disease but no humeral involvement. The 3 patients had an estimated blood loss of 1400 mL, 1100 mL, and 350 mL, compared with an average of 280 mL in the control group. The first 2 cases required 4 units of packed red blood cells intraoperatively, and both were not managed with bisphosphonates. Paget's disease of the humerus leads to more intraoperative blood loss and higher blood transfusion requirements, particularly in cases not managed with bisphosphonates. [. 2021;44(4):e614-e619.].
