Summary

This study compares two types of nerve blocks for pain control after hip surgery: the PENG block and the femoral nerve block. Researchers will measure pain levels and leg muscle strength in 100 adults aged 40 and older. The goal is to find which method provides better pain relief while preserving muscle function.
