Osseointegration of Hydroxyapatite-coated Femoral Stems in Femoral Neck Fractures Over 80 Years

• Conditions: Femoral Neck Fractures
• Interventions: Procedure: Hemiarthroplasty with hydroaxyapatite coated stem

• Registration Number: NCT04773145
• Lead Sponsor: Central Hospital, Nancy, France

Brief Summary

This study aimes to prove that osseointegration of hydroxyapatite coated stem is possible for patients over 80 years with femoral neck fracture, without the risks of cemented stems.

The hydroxyapatite has a local effect which can improve cortical index.
