Summary

This study looks at how different strengths of the numbing drug ropivacaine affect how fast and how long an ankle block works for people having bunion surgery. About 174 adults will be randomly assigned to receive one of three concentrations. The goal is to find the best dose for quick, long-lasting pain control with fewer side effects.
