Intraoperative cell salvage reduces postoperative allogeneic blood transfusion and shortens off-bed time in simultaneous bilateral total hip arthroplasty: a single-center retrospective study.

Background: Simultaneous bilateral total hip arthroplasty (SI-THA) results in more blood loss and a greater need for postoperative allogeneic blood transfusion (ABT).

However, there are few studies on the role of ICS in SI-THA.

Study on glass-forming ability and corrosion performance of Ca-based biomedical materials.

Stress shielding and the need for secondary surgery are the two major challenges faced by permanent metallic implants, and the emerging Ca-Mg-Zn calcium-based bulk amorphous alloys, with Young's modulus comparable to that of human bone, good biocompatibility, and in vivo degradation, are highly promising materials for bioimplants.
