Denosumab in Enhancement of Bone Bonding of Hip Prosthesis in Postmenopausal Women

• Status: Completed
• Trial end date: 2017-12-31
• Target enrollment: 0
• Participant gender: Female

Summary

This randomized clinical trial will evaluate the efficacy of an antiresorptive osteoporosis drug (denosumab) in prevention of periprosthetic bone loss and in promotion of implant osseointegration (bone bonding) in postmenopausal women after total hip replacement. The investigators assume that denosumab prevents periprosthetic bone loss and enhances bone bonding of the hip stem in postmenopausal women.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No
