Abstract
Osteoporosis and osteopenia can affect patients undergoing arthroplasty of the hip, which is typically recommended for patients with severe osteoarthritis or elderly patients with a femoral neck fracture. Preoperative screening for this type of bone loss could be helpful to patients and prevent poor outcomes due to the rate of underdiagnosis of osteoporosis, which can reach 73% in patients undergoing hip arthroplasty. Complications associated with low bone mineral density include periprosthetic fractures as well as an increased revision rate. Although the benefit of antiresorptive medications postoperatively has been demonstrated, when administered preoperatively, worse outcomes were reported compared to its non-usage. Surgical management is as important as pre-medication. According to general recommendations, cemented implants provide greater benefit in osteoporotic patients. However, when using cementless implants, ribbed stems, straight tapered stems, stems with medial calcar contact, and titanium-composed stems can be used to prevent periprosthetic loss of bone mineral density; however, they should not be placed in a varus position. These stems can also be coated with zoledronate and other products.
