Summary

This study looked at 618 people aged 18 to 70 who had hip replacement surgery to see if they developed new low back pain afterward. Researchers tracked how many patients experienced their first episode of low back pain after the procedure. The goal was simply to observe and measure this link, not to test a treatment.
