Summary

This study looked at a special metal nail used to fix broken hip and thigh bones. The nail has a coating to help prevent infection. Researchers followed 149 adults for 12 months to see how well the bone healed and if there were any problems. The goal was to confirm the nail is safe and works as intended.
