Short-term Functional Recovery Between Early- and Late Bisphosphonate Treatment Following Hemiarthroplasty

• Status: Unknown status
• Trial end date: 2017-10-01
• Target enrollment: 0
• Participant gender: All

Summary

Femoral neck fracture in the elderly is one indication for initiating osteoporosis treatment. Bisphosphonates remain the first line therapy; however, many orthopaedic surgeons concern regarding their effects on fracture healing process. Therefore, therapy is usually delayed for a period of time. To the best of our knowledge, there is no scientific data to support whether bisphosphonate treatment should be given immediately after the surgery or it should be delayed.

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

Details
