This clinical trial focuses on patients undergoing surgery for hallux valgus, commonly known as a bunion, which is a foot deformity where the big toe points toward the other toes. The study examines the use of ropivacaine, a local anesthetic medication that blocks pain signals, administered through an ankle block procedure where the medication is injected around the nerves of the ankle.
The purpose of this research is to compare how different strengths of ropivacaine (0.25%, 0.5%, and 1%) affect the duration of pain relief after bunion surgery. The medication will be given before the surgery using ultrasound guidance to ensure accurate placement. Patients will receive one of these three different concentrations of the medication.
During the study, which lasts 48 hours after surgery, the medical team will monitor how long the pain-blocking effects last, how quickly the medication starts working, and how it affects leg movement. They will also track pain levels and the need for additional pain medication. The study uses specialized techniques to deliver the medication precisely to the nerves around the ankle to provide pain relief during and after the surgery.
