Summary

This study looked back at the medical records and X-rays of 100 adults who had surgery for a broken thigh bone just above the knee. The goal was to see how well different types of metal plates held the bone together while it healed. Researchers checked for problems like the plate breaking or the bone not healing properly. This was a review of past cases, not a test of a new treatment.
